As we know that CNC machines are the most dependable, reliable and long-lasting parts of equipment for any woodworker. However, time and again, many complexities have been recorded in this durable machine. Programming complexities and due to the failure in some other components in the CNC machine have been a cause of malpractice and frustration.

Usually, there is a fact behind these issues. These small but irritating issues are compounded due to lack of attention towards the machine which can happen by either using it wrongly or poorly maintaining it.

Nevertheless, before going into the depths of the problems and their reasons; let us take a moment to understand what a CNC router machine is and how it works.

What is a CNC Router Machine?

CNC stands for Computer Numerical Control. A CNC machine is an electro-mechanical device that is used to manipulate and control the machine-shop tools and devices with the help of computer programming.

Mostly, CNC machines use a platform that allows for a computer-driven cutting tool to carve a material in all the dimensions. This, CNC machine, can be used by programming it to make precise, repeatable cuts on lowly elevated or flat wood or plastic projects. For high-level usage, a CNC machine can be used by applying it to plasma and laser cutters as well.

The recent changes in technology have led to the marketing programming methods which are used by competing for machine manufacturers. However, the G-code is still something that is the core of CNC machining.

Furthermore, because of innovation and modernization scrap is being reduced which has turned out to be a time and money saver for the companies using the CNC machine. Besides, it is also eliminating the damage to their machining centers by using simulation, verification, and optimization of software. With unique innovative ideas and features, many companies have started to supply these software packages.

What’s interesting is that besides allowing the manufacturer to replicate the machining of a new part, these software packages help in verifying the tool paths to eliminate collisions and crashing and optimize production. Apart from that, they also allow the detection of inconsistency by measuring and analyzing.

How does a CNC Machine Work?

A way to transform a normal piece of material like a block of wood into a finished product with the help of controlled material removal process is called a CNC machine. Similar to other forerunner development technology, CNC works on the digital instructions it receives from the computer-aided manufacturing or computer-aided design file.

Given digital instructions are interpreted for cutting prototype parts by the CNC machine. This practice automates the highly technical and labour-intensive task and thus, becomes a reason for an increase in productivity. When the material is critical, the prototype parts can be created by providing automated cuts. These automated cuts are a reason why the speed and accuracy of the overall process are improved.

Moreover, it has quite a few similarities to 3D printing. Just like 3D printing, CNC has a computer supplied digital code that is passed onto the tool which helps in creating a finished product. Since the entire creating process is installed in a set of precisely coded directions, the process is quite faster, more efficient and less error-prone in comparison to hand-work.

Quite often these processes involve the use of different sets of multiple tools to make the solicit cut. CNC machines can combine tools into common cells from which machines can draw the required work.

Basic machines rotate in one or two axes whereas the advanced machines rotate a little more laterally in the x and y-axis and longitudinally in the z-axis and sometimes these machines rotate either in one or more than two axes.

Multi-axis machines are good enough to flip parts over automatically thus, allowing you to remove material that was below it. This process removes the need for workers to flip the stock material, hence, removing the manual intervention and increase the productive time.

Some issues that can arise while using a CNC Machine and their Solutions

Irrespective of the fact that CNC machines are fast and efficient, there is a thing about these machines which is not unerring.

However, just like other machines, this machine too can develop issues over time. Maybe it can be due to the user’s wrong usage or due to lack of maintenance. Like other tools, there are a few things that a user can do during the normal practice that can result in damaging these machines. Nonetheless, there are steps that a user can take to keep them in good shape for its smooth working.

As a user, one knows that they might run into several problems that can lead to an indefinite number of issues and errors within a CNC machine. Some of these issues are more of a run-of-the-mill than the big ones. Hence, these small and tiny issues are the one which gets neglected and overlooked.

From burn marks on the finishes of the machined parts to the immobilization of different moving parts to inaccuracy in machined parts or problems occurring due to improper power supply, here are a few of these small but common problems occurring in a CNC machine.

● Poor or Improper Maintenance

● Improper Settings or Tools

● Poor or Improper Programming

● Overheating of the machine

● Inadequate skills of the worker and training

● Power supply problem

● Automatic tool changing problem

● Vibration/chatter of the machine

● Clamping/unclamping problem of chunks and fixtures

Poor or Improper Maintenance

This is a mainstream problem that is ignored quite often. Modern machines that come with constantly moving mechanical parts like CNC machine tools require regular cleaning and maintenance which can keep them running in the best possible way.

Howbeit, the lack of attention in clearing the dirt materials and other debris could become a reason for the build-up in the imprecision of the machine. Thus, it provokes failure in the machine.

Measure to Prevent This Problem:

The question now arises ─ how to prevent this problem?

The prevention of this problem is quite simple, the machine holders and the operators need to understand the nuances of the machine while buying this. Moreover, they need to make sure that they go through the detailing quite thoroughly, follow the detailed maintenance regime for the tools which are being used in the machine.

Also, the operator and the owner should make sure that levels of coolants or airflow, like air filters, are regularly checked. Doing this ensures that the operations continue smoothly and are uninterrupted. It is a point to note that having an overheated spindle can result in having a choked air filter in the cooling system.

Improper Settings or Tools

Picking a wrong cutting tool, quite often, might result in a work which is poor in quality and is low with regards to its material finishes. This poor quality can be experienced by the rough edges, cutter marks on the surface, burn marks or raised marks on the material’s corners and edges. Extensive usage of a tool can also result in this kind of error.

Moreover, the poor material finishes can be due to either of the bluntness in the tool which is in use or could be due to improper feed of speed ratio. Wrong feeding of such factors can also be caused by the wrong dimensions of the toll for the job at hand when things come to sizes, quality or match with the material.

Measure to Prevent This Problem:

To solve this issue, one needs to be very attentive while handling the machine and should give importance while picking up the right tool and also, while setting the material for the job in hand.

>Poor or Improper Programming

Most of the highly trailblazing equipment is controlled by CNC computers and much of the problems in the CNC machines pop-up when the programming of these machines are wrongly done. This issue may arise due to lack of knowledge of the G and M codes (which are used for the controller of the machine), by setting up the tools in a wrong manner, or the worker inputs the wrong data variables.

Measure to Prevent This Issue:

However, these issues can be resolved by providing adequate training to the new operators. The machine owners can make sure that the new operators are given proper training in different ways in which CNC machines can be programmed.

Extensive user manuals and training, operation of the machines and motion sequencing should be requisitely given to the new operators by the machine suppliers or experienced operators on the shop floor.

Overheating of the Machine

Using a CNC machine for a long duration and high volume can result in overheating. There will be instances where the CNC machine can hit a temperature of 150 degrees or more due to excessive usage. Hence, this could harm the machining which can produce poor quality work and also, could hamper the output of the machining job.

Furthermore, the variations in the rising temperature in the workshop can also play a part in CNC machine overheating. Opening doors or windows so that air/wind could come in can affect the accuracy of the work carried out by the machine tools.

Moreover, having a nice wide window where the sun can shine freely alongside a cold blowing air conditioner is good for the operators but this can affect the finished product from the machine as it can get distorted on its axis.

Also, overheating of a machine spindle could happen due to excessive use of the machine at the highest rpm. A spindle with Grease Lubrication should not be used at extensive hours for full rpm.

Measure to Prevent This Issue:

There are ways to avoid this, one can make sure that they clean all the channels and clean the dirt, soil, and material at a regular interval. Having a calendar to maintain the daily cleaning schedule of all the metal shavings as well as the liquids used during the cutting process can be quite handy in saving the machine from overheating.

To prevent overheating of a machine spindle, the operator can use a spindle with Air-Oil Lubrication or an Oil-Jet Lubrication spindle which is a better option as they have no problem in running for the longest hours.

Inadequate Skills of the Worker and Training

With the rapid increase in the usage of computers and programming, CNC machine tools need an operator who has adequate knowledge, has the skill set and is well trained to handle a different set of requirements of this machine’s programming language.

Without the right planning, organization, and programming skills the worker will be unable to fetch the required yield from these machines irrespective of them having machining skills and experience.

Measure to Prevent this issue:

To make sure that this error does not happen, the machine owner needs to make sure that they are hiring the right machine operator who is good with visualizing and is capable of designing the machining process, selects the right tool and sequences for the task and is good in writing appropriate programs.

Power Supply Problem

In many cases, it may happen that the CNC machine tool’s display or different parts might not work due to issues with the power supply.

Measure to prevent this problem:

However, to rectify this, one should make sure that adequate power and voltage is supplied to the input side. One should also check whether the output or secondary side is properly working or not.

In cases where there is no power or the voltage reading turns out to be low then considering to disconnect the output wires with the power off is a good idea. Moreover, one can check the power supply using power-up and if it wants to be sure of it then it can go through the rechecking process of the output side. They can also check whether the LED on the machines are working or not, and could also have a look at the fuses.

A stable power supply is a prerequisite for working with a CNC machine. It is the foundation for trouble-free operations performed by a CNC machine tool.

Automatic Tool Changing Problem

Often, there will be a time where a user will face challenges regarding the automatic tool changer in your CNC machine’s tool.

Prevention Methods:

Nevertheless, these minor issues can be dealt with by knowing about every step of the tool changing process and how to troubleshoot the machine by diagnosing what went wrong.

Moreover, one should also keep a check on the base, the gripper arm, tool holder, support arm and tool magazines working and ensure that they are running smoothly.

Also, they should examine the action of swiveling and mechanical arm action for their proper working. One must regularly clean the chips and coolant of the automatic tool changer and tool holder.

Vibration/Chatter of the Machine

If the CNC machine vibrates while working then there is a significant possibility that this can reduce the life of the tool, affect its durability and will undermine the quality of the machined part. This can be observed by listening to the noise generated by the machine.

Prevent This issue:

To solve this issue, the operator needs to diagnose the workpiece chatter or the tool chatter. They can also alter the RPM of the machine. By doing so, they ensure that the frequencies of the machining process do not resonate with the material frequency.

Clamping/Unclamping Problem of Chunks and Fixtures

This can be a considerable issue when the piece required to be worked upon cannot be securely gripped by the chunk or continually shifts or vibrates in the process.

Measures to Prevent this issue:

This can be resolved by:

● Checking whether the parts are correctly positioned for a secure clamp.

● One should also check the hydraulic pump and its pressure.

● If the chuck is working based on the MDI M-code command.

● Check whether or not the lubricant is adequately used for gripping the material.

● Avoid the point gripping instead should opt for wider surface gripping.

● Must check whether there is dirt or not, cause dirt and debris to can play a part in malfunctioning of the machine.

● Check for the working output of solenoid. If the output is working then a broken wire at the connector could be a problem.

● If the chuck does not open/close, check to see if the footswitch is working – see if the contacts are still working and that the wires are not broken.

● Look for whether the drawtube connecting the hydraulic cylinder and the chunk is working or not.

How To Choose The Right CNC Bits?

Moving on from the errors and solutions, the question now stands here is, how one can choose the right CNC bits?

As discussed above, CNC is solely responsible to provide good quality to the finished work; hence, taking a risk in choosing the CNC bits could turn out to be risky. Here are a few ways in which a right CNC bit can be chosen:

Application and Material

The material under the cutter has a lot to do with the type of CNC bit an operator needs. Probably, the woodworker might be working with wood or is manufacturing a large amount of plastic or aluminium; for these materials, the CNC router is required.

Picking the wrong bit for the chosen material can hamper the processing of the machine and can destroy the bit and the machine. Some materials require the use of multiple CNC bit types but it is best to use just one type.

When melamine or plywood is placed under the cutter, it is advisable to use compression bits to avoid chipping or tearing of the material.

If the operator is a new entrant in the world of CNC routing then they should prefer for a multi-purpose CNC bit, which uses two-flute spiral bits. The versatile bits can be used on a variety of materials.

Speed and Finish

While making smooth cuts is a priority, there are some projects which demand a quick finish. Speed and accuracy are the most important consideration while picking the type of bit for processing.

For a speedy finish, one must know that feeds and speed depend on a few factors.

● Horsepower of the spindle

● Panels held down by clamps or vacuum

● Stability of CNC machine

● Condition of collet

One should gradually increase the speed of the cutting rate as instantly cutting at high rate makes difficult to gauge the optimal speed.

It is crucial to keep in mind that chips that are too large might break a router bit. Whereas, chips that are too small can turn your waste to powder and dull the bit.

When things come to finishing, the primary goal is to make quality cuts. The more flutes a bit contains, the higher the quality of work the machine gives.

Daily Needs of a CNC Machine:

Apart from choosing the right CNC bit, the operator should understand that the machine also has its daily needs to process the work smoothly. Here are a few daily needs of the routing machine and the operator must follow these needs:

1. Keep the machine clean: After the end of every shift, check the rack, ball screws and linear bearings, clean them if there are any chips surrounding the sensors.

2. Change worn tooling: Change the damaged or worn collets, cover nuts and tools as they can affect your cut quality.

3. Keep a check on the machine: Look for broken parts that affect can the machine’s output or safety of the employees.

4. Close the machine at EOD: Avoid using the CNC machine all year long, as it can get extremely hot. Turning off the machine can reduce the chance of burning the connectors and keep the employees safe from unexpected power surges.

5. Delete old files: Efficiency of the machine should be a top priority of the owner. Hence they should make sure that they delete the old files from the system and keep a back-up in an external file.

6. Timely greasing of the bearings: It’s recommended to oil the bearings at the end of every shift and grease them appropriately.

7. Replace the vacuum pump oil: One should change the vacuum pump oil after every 20,000 hours of use.

So, here was the cover of things that could affect the working of a CNC machine and also, were some of their treatments. Machines are also like humans, they require nurturing and caring. Excessive use and a little carelessness can harm the working of the machine. However, a proper diagnosing of the problem can help prevent a huge loss.

When a person thinks to start a woodworking shop, it is obvious that the person will visit different forums for opinions on how to invest money for their shop.

With no shortage of opinions on the forum, these opinions will likely create confusion in the head of the person. However, the thing here is that one should know that their woodworking shop is their source of income and they should understand these things to help in prioritizing the purchase of the shop:

1. Buy instruments that are flexible in the sense that can complement other instruments.

2. Taking from the first point, flexible instruments keep the work moving.

Hence, it is important to keep these points in mind while investing. However, the point to note here is that to keep moving the work smoothly and to be flexible as per the needs of the trade, one has to be very careful with their choices in investing.

Nevertheless, in this article, here are a few tips that could help in the making of a good woodworking shop.

Shopping Strategy:

The approach should be simple and should not include buying cheap products. When a cheap product does not perform or fails badly then buying on price often costs a user more in the longer run.

The trick should always be of searching for quality tools that can be bought at pocket price. And, after buying, one should know how to unlock the maximum potential of that instrument.

The strategy should always be, irrespective of the cost, to buy basic and versatile tools before adding any kind of specialized tool.

Types of Tools to Have in the Shop:

There are a variety of tools available in the market. And having each type of these tools in a tool kit is essential for a woodworker. To sort things out, here is a list of tools and things that are essential for woodworking.

● Tools

1. Table Saw
2. Plane Thicknesser
3. Woodturning lathe
4. Router
5. Circular Saw
6. Random orbit sander
7. Chisels and saws

Power Tools: Power tools make the life of a woodworker easy. Here is the description of some of them:

Table Saw: Table saw has to be the first purchase for any woodworker. Woodworking is cannot be termed completed if the table saw is missing from the list of equipment. Furthermore, the table saw serves as the focus for many tasks that could come in the future. One has to consider some space in their workshop or home for a table saw as it is quite large compared to a normal saw.

The blades of the table saw are bigger than a circular saw. They consist of a high-speed motor fixed over a flat table beneath it. The blade rises out of the table bed to adjust the depth of the cut. Table saws are pretty good when it comes to preparing identically sized pieces or making several rips cuts.

Table saws can take masonry blades and metals but the thing to keep in mind is that the design of the blade should match the motor’s round per minute.

A table saw, since it is well balanced, can deal with the cutting of various sizes of wood with efficiency and accuracy. This is the reason why it is the heart and soul of a woodworking shop. Furthermore, a woodworker considers this as the centerpiece, hence forming their arsenal around a table saw.

Plane Thicknesser

A woodworking machine which helps in planning and smoothing of large sections of timber to get the right size of wood as per the requirement of the project is called a plane thicknesser.

A plane thicknesser comprises of three parts:

1. Drum Cutting Blade
2. Feed-in/feed-out rollers
3. Adjustable level table

● Drum Blade: It is a metal cylinder holding blades made to rotate at high speed to plane the wood.

● Feed-in/feed-out roller: These supports are placed before and after the planer so that it can support the wooden plank when it is put in and when it goes out from the machine, thus, making the process a lot safer.

● Adjustable level table: The adjustable level table is a platform for holding the timber at a correct distance from the drum blade for trimming the thickness of the wood as per the requirement of the project.

When using the machine, it is good to consider the fact that one must not try to get the required thickness in an attempt as that can make the planner jump, tear and could give a rippled finish. Plane the timber in small amounts to get the thickness as per the requirement of the project.

Moreover, to achieve a flat, smooth and constant plane, one needs to make sure that the other side which slides over the working table should be flat.

Woodturning Lathe

A machine that converts a piece into a chosen shape irrespective of it being a spindle, bowl, or different decorative wood items is called a wood lathe machine. A piece of wood is attached to a spinning arm and multiple tools are used to provide shape to a piece of wood while it is spinning.

The lathe has played and is playing a crucial role in the development of civilization. Production of wheels and making various kinds of furniture such as tableware, and parts of mill and pumps, jewelry-making and many other important developments were some productions where the lathe was used.

Mostly, a lathe comprises a spindle and tailstock where the desired wood, which the woodworker wants to turn, is attached. The use of multiple bladed tools and the tool rest is used to trim the outside of the wood. In doing so, the bark is taken off and is shaped until the desired shape is not attained.

Furthermore, a woodworker can make use of the hollow which comes out of the wood to make vessels such as utensils, vases and decorative items.

Router:

A high-speed process in which wood is cut, trimmed and shaped is called routing and the machine used for this process is called a router. Wood routing is a process that is used to shape the wood by producing finished edges and shapes. Materials that are difficult to shape can be shaped neatly using a router.

A CNC router is a convenient tool to use in comparison to a spindle moulders when it comes to fishing light work. A router has a higher conversion rate than a spindle moulder as it works at a high speed thus, finishing the job much quicker.

Circular Saw:

Circular saws mainly use a toothed blade which is usually between a 7-¼ and 9 inches in diameter. They are also referred to as a buzz saw or the most popular name of a circular saw of called Skilsaw.

Circular saws are very much like table saws. It is a very common workshop equipment. It is a very flexible tool with a high level of portability. It is a handheld power tool with a rotating blade that is pushed across the wood to cut it through.

The prime purpose of a circular saw is to cut the wood and soft materials, thus, it can also act as a table saw. Moreover, this saw can be used to cut very tough materials like metals with the use of a suitable circular saw blade.

Random Orbit Sander:

A random orbit sander works alternatively by spinning the sanding disk and moving it in an elliptical path. The random sanding action helps in preventing the swirl marks. However, the direction of the grains is not an issue when sanding is being performed.

Usually, the random orbital sanders come in 5 or 6 inches sizes that are as per the sanding disk in use. A 5-inch sander, because of their better mobility, is mainly used for DIYers purpose. With circular pads, the round orbital sander is different from an orbital finish sander.

This sander is controlled by the palm of the woodworker’s hand and a light touch is all these sanders need to make them do the desired work.

Mostly, the round orbit sanders come with a vacuum system that gets activated when the sander is turned on. The fine particles coming out of the wood are sucked through the holes that are embedded in the surface of the sander. These particles get deposited detachable canister.

Although there is a vacuum system, woodworkers are advised to use safety goggles and respiratory masks as a safety measure for their health purposes.

Chisel: There is a need for a chisel to clean out saw cuts and joints. Thus, a woodworker must possess a chisel in his/her arsenal. Built of high-alloy carbon steel or chromium-vanadium alloyed steel, chisel requires a hardwood grip with metal caps, which are the best, for holding purposes. This type of grip prevents the end of the handle, which is getting hammered by the woodworker, from becoming distorted.

Chisel is one such tool that requires the use of both hands. Because of this, a woodworker can enjoy the power and control over a chisel while cutting wood away. One thing to keep in mind is that the claw hammer will destroy the end of a chisel if not used properly.

● Health, Safety, and Workwear (PPE)

Workshop Vacuum System:

Once you start woodworking, you will soon realize that sawdust gets everywhere and a broom alone is probably not enough of a solution. Not only is having a system in place to deal with dust important for the air quality of your shop and what you are breathing, but I feel more productive in a clean shop without sawdust all over everything.

It will not take time for any woodworker to realize that sawdust will be a pain in his/her eye. In some cases, the broom alone will not be enough to get rid of the widespread sawdust. For this reason, a woodworker is advised to have a vacuum system to deal with this massacre. With a vacuum system, the air quality will be taken care off and the shop will be much cleaner in comparison to the brooming one.

Since large workshops have large dust extractors but there are custom vacuum cleaners available in the market that can fit the size of a workshop under a planned budget.

Other Equipment:

Apart from the aforementioned things, a woodworker must make sure that he/she has covered the basic aspects of the woodworking workshop. Small things can pull stunts that even power tools cannot pull off. Hence a woodworker should make sure that they are covered with the below-mentioned items in their store.

● Bench Vice and storage:

A heavy-duty wood clamping vice that is attached to a workbench is called woodwork vice. Due to its design, it is capable of heavy-duty work. It has a strong metal construction and wide jaws, a woodworking vice can withstand large amounts of pressure when the work is on.

For any bench, there is a need for easy-access storage otherwise things will clutter over the benchtop making it a messy affair. Thus, having drawers that mount directly under the benchtop fits the scheme of things very nicely.

● Abrasives, cleaners, and finishing:

After working hard to get the desired shape and size of the wood, a woodworker needs abrasives, cleaners and finishing materials to get the finishing right.

However, the choice matters a lot when it comes to these items. A look-out for cheap stuff can get the finishing wrong. Hence, it is advised to research properly about these materials and understand the surface the project is involved in before investing in these materials.

Putting money in a woodworking shop can be a rugged effort and will require substantial thinking from the woodworker. However, if one inclines with the thoughts mentioned above then it will become easier for the woodworking companies to understand where they want to lay out their money.

The advanced machinery can operate on their own without the interference of humans. You just need to give the command to operate the machine. The unsurpassed performance, productivity, accuracy, and reliability make the high-tech CNC machine one of the most popular inventions.

2. What is Plasma Cutting Technology

Speaking in simple words, a plasma cutting machine is one of the most interesting and powerful tools of the 20th century. The basic principle of physics is used to harness the fourth state of matter and the machine works with magical results. Plasma cutting is a process that uses a high-velocity jet of ionized gas that is released from the constricting orifice.

The plasma machine generates high-velocity ionized gas to conduct electricity and then operate on a piece of material. Plasma cutting machine is commonly used for cutting metals for a variety of purposes. The plasma heats the workpiece and melts the material. The high-velocity stream of ionized gas blows molten metal thereby giving shape to the product and making the cut.

Plasma cutting is one of the effective ways of cutting different types of materials, both thin and thick. The hand-held plasma torch can cut up to 38 mm (1.5 inches) thick steel plate while computer-controlled torches can cut steel up to 150 mm (6 inches) thick material. Since the plasma cutting machine produces a very hot and localized cone-shaped tool to cut the materials, they are also used for cutting sheet metal in curved or angled shapes.

The plasma cutting machine emerged in 1980 as a productive way to cut sheet metal and plate. The conventional plasma cutting machines were large and inefficient than today. Earlier, the CNC plasma cutting machines were also limited to cutting patterns and parts in flat sheets of steel.

3. What is Plasma Cutting Machine used for?

The plasma cutting machine utilizes the heat of the high-temperature plasma arc to melt the metal material used for shaping. The high speed of this advanced machine is used to eliminate the molten metal from an incision. Plasma machines are controlled with CNC. CNC table allows a computer to control the torch head of the plasma machine to produce clean sharp cuts. Most modern CNC plasma cutting equipment is capable of multi-axis cutting thick materials enchaining the opportunities for complex welding that seems to be impossible otherwise.

The plasma cutting machine cuts out different shapes and designs of metal that are then combined to create artwork. Auto repair shops, salvage yards, and construction sites often use plasma cutting machines to cut sheets of metal. Depending on the experience of the user and tool of the cutter, very fine and precise cuts can be made.

Plasma cutting machine is designed to produce sharpest and best quality cuts that can be only achieved with plasma machine. A CNC plasma cutter uses a plasma torch to cut different types of materials in different shapes and sizes. Stainless steel, carbon steel, copper, aluminum, and brass are some types of metal materials that are used by plasma cutting machine for cutting. Plasma cutters often cut sheet metal or square/round metal tubes.

OMNI CNC offers the most versatile CNC plasma machine for smooth cutting and clean cuts. This computer-controlled equipment can create intricate as well as complex patterns on the surface of the material. CNC plasma cutting machine creates a prototype of the objects with the ability to cut and carve with precision. OMNI CNC plasma cutting machine that can effortlessly cut 5mm and 3 mm thick steel tubes and sheets.

4. Choose Right Plasma Cutting Machine for Your Facility

The quality of the cut is very important to determine the type of machine you would buy for your shop. Ideally, the good quality of cut makes better-finished products. The more precise, clean, and smooth edges that plasma cutting machine creates, less metal is wasted.

There are some factors that should be considered while choosing a plasma cutting machine for your shop/facility. Let us take a look at some of the factors underlined below:

• Thickness of the Metal Used

The sources of most of the plasma cutting machines are rated on their ability to cutting and amperage. If you cut ¼” thick material, you should consider a lower amperage plasma cutting machine. However, if the thickness of the metal is ½” then you should look for a high amperage unit. Every unit has an optimal range of thickness and it should match up with your needs. Talking in general terms, a ¼” machine has approximately 25 amps of output, a 1/2″ machine has a 50-60 amp output while a ¾” – 1″ machine has 80 amps output. So, you should match up with the requirements.

• Optimal Cutting Speed

When a plasma cutting machine, the manufacturers provide cutting speed for and the thickness of the metal is measured in IPM (inches per minute). If the metal most frequently cut is ¼”, a machine that offers higher amperages will be able to cut through the metal much faster than a low current unit. For production cutting, the thumb rule is to choose a machine that handles approximately twice the normal cutting thickness. Take, for instance, to perform for a long time, fast, quality production cuts on ¼” steel, you should choose a 1/2″ class machine. Like welding equipment, the duty cycle is considered as important for automated and continuous cutting. The duty cycle is the time that is consistently used for cutting before the machine or torch overheats and requires cooling.

5. How can the Plasma Cutting Machine Operates?

A plasma cutting machine is capable of cutting thick metal sheets in any shape and size. This computer-controlled machine gives instructions through a computer over the manual handheld plasma cutter. It is compatible with optional CNC parts and improves the accuracy, flexibility, and productivity. Regardless of the size and shape, plasma cutters function on the same principle and constructed on the same design.

Plasma cutter operates with pressurized gas through a narrow channel. You will find negative electrodes in the center of the channel. The negative electrode gets power when you touch the top of the nozzle to metal thereby creating a circuit. The powerful spark is generated between the electrode and the metal. As the inert gas passes through the channel, the spark heats the gas until it reaches the fourth state of matter. This type of reaction creates a stream of directed plasma, approximately 30,000 F (16,649 C) and moving at 20,000 feet per second (6,096 m/sec), thereby reducing metal to molten slag.

Most plasma cutting machines have a pilot arc that works on high frequency to conduct electricity through the air. This happens to be very smooth at first but with time high frequency can interfere with computers or office equipment.

In the past, the plasma cutting machines were very expensive and they were generally used for cutting huge metals but in recent times, the cost and size of the plasma cutting machines have dropped. This all-inclusive tool gives artists the ability to make bevel cuts, bore precise holes, and cut in just about any way it can be conceived.

6. Plasma Cutting Machine and its Maintenance

Before operating the machine, it is very important to take a look at measures of cutting machines, let us take a look at some of the measures:

• It is very important to check the leakage of the air circuit system, plasma power supply, cutting torch before work.
• Ensure that the cutting nozzle and the electrode are in order with the setting of the plasma machine
• Check the gas pressure, air filters, air compressor, etc.
• The power source and the gas source of the machine should be shut off when the machine is kept in the rest position for a long time.
• Regularly oil the lifting mechanism of the machine such as ball bearing, screw, linear guide slider.
• Check direct current motor brush every year. The excessive endurance on the DC motor will affect the performance of the motor and even pose damage to the motor.
• Clean accumulated metal dust from the machine and ensure all air filters are clean.

7. Portability and Durability are the Advantages of Plasma Cutter

The plasma cutters are interesting and among the most powerful tools of the 20th century. Many users operate a plasma cutting machine for numerous cutting applications. This machine can be easily moved from one place to another. Portability is one of the greatest advantages of this machine.
