CNC Machining For Countertop Production

Countertops are created from several types of stones. The most common stone in use is Granite. Marble is also a preferred material. To achieve a perfectly positioned countertop involves several factors.

• Cutouts for the sink
• Seams to appear seamless
• Cabinet positioning for proper placement of granite / stone slab

Stone is heavy and proper supports are needed as the countertop needs to last a longtime; probably a lifetime. The alignment and cutting the openings of the sink is a critical element in the function as well as the decor of the kitchen. Finally is the edging finish to the countertop. There are several edging finishes such as

• Half round
• Fully rounded
• Half round with bottom beveling
• Fully beveled

Creative Stone Countertops Pawtucket

Presently a digital template of the countertop is produced as a computer file ensuring that measurements are accurate. The advantage of digital templating by laser ensures that accuracy is achieved due to the precision involved in digital measurements. This also prevents human errors. On the computer screen, the image of the stone slab is over-layed with the image of the digital template and everything is checked once again.

The stone slab is mounted on the worktable of the OMNI CNC 1325, which is a versatile CNC router for stone routing operations. CNC machining by this robust state of the art stone router is precision combined with speed. The stone slab is cut as per the image and edged; Cutout pieces for under mount sink and holes for faucets are drilled. The reason for precision measurements taken earlier become clear as the under-mount sinks match perfectly and the half-round edging under the sink allows perfect fitting. Polishing the back side of the coarse stone slab as well as the underside of the overhang gives a smooth feeling when felt. To make the seams as seamless as possible the CNC machine uses polishing tools to make the surfaces of the joints smooth.

Quartz Engineered Stone Countertops

Countertops are manufactured from 2 cm and 3 cm quartz, or granite or engineered marble stones. Mitered saw edging is possible as the heavy-duty spindle is capable of performing profiling and machining with ease. Employing a higher rated spindle allows greater torque at lower rpm (revolutions per minute). This gives the added facility of honing, brushing and texturing of different stones.

OMNI-CNC Routers are equipped with NC Studio control system or DSP handle controller or Syntec PC platform. Capable of spindle speeds of 24,000 rpm the CNC machine is equipped with water cooling system that is ideally suited for countertop production. High degree of tolerance of plus or minus 0.05 mm (millimeter) for a machine that works with heavy stone material is achieved because of a robustly built frame that is reinforced by ultra-thick steel tubes with welds that are quenched. To facilitate the easy movement of the stone slabs the machine table is equipped with a coolant tray with wheels.

CNC Routers are Ideal for Puzzle Manufacturing

Puzzle manufacturing has undergone several iteration over the years; Similar to changes in technology, engineering a puzzle in the present 21st Century is completely different from methods employed in 1760 by John Spilbury (a cartographer – meaning a person who made hand drawn maps) when probably the first puzzles were created. John Spilbury pasted his maps on thin pieces of cedar panels and cut them using a marquetry saw. Marquetry is the tool derived from the ancient art of inlay where a solid piece of material is cut out so as to receive another material to form a surface patterned finish.

Puzzle Manufacturing CNC Routers

Spilbury’s maps soon became popular and the art of puzzle making by the jigsaw (marquetry tool) method became widespread; with advances due to the Industrial revolution and new printing technologies the offset printed pictures soon found their way and glued onto cardboard as well wooden veneers and die-cut in various shapes. The market for puzzles reached its peak during World War 2 and thereafter as Jackson Pollock’s painting Convergence became a best-selling puzzle and enjoyed by thousands of Americans. Wooden puzzles are making a comeback after all these years primarily for affordable CNC laser routers that have allowed small custom wooden puzzle manufacturers to reinvent the art. Lasers can cut with precision, as it is a concentrated beam of light that does the cutting. The beam is very thin and the cut is also clean leaving no burrs. The term jigsaw puzzle is apt for laser cut puzzles as intricate shapes can dovetail into each other when finally assembled.

Sign making CNC routers

Sign making CNC routers such as the OMNI CNC 1318 model is also capable of puzzle cutting as well as 3 dimensional character cutting. A powerful spindle operating at 24000 rpm rated at 1.5kw and protected with digital spindle temperature monitor is the perfect tool for craftsmen to produce wooden based puzzles. The advantage of the vacuum combined T-slot enables proper material hold down and the linear guide on 3 axis is the perfect traverse system that can work 24 x 7. OMNI-CNC Routers are based in China and among the top suppliers of affordable CNC routers.

Requiem for the Departed to Live Forever Via Tombstone Engraving By CNC Router

Benjamin Franklin wrote in 1789 after the Constitution of America was established describing it as an appearance that promised permanency but in this world there are only two things that are permanent death and taxes.

Tombstone Engraving by CNC router

This blog is more about perpetuating death and less about taxes. Most people like to be remembered – by the people who are alive want to remember the dead and so it became perhaps one of the earliest professions of a tombstone engraver and the engraver’s place of work was the cemetery. Even today, it is common for a stone-mason and his assistant busy chipping names and dates on granite stones (if the people are middle class) and marble (if the people are wealthy). It is also normal for the stonemason to be replaced by a small workshop equipped with a stone engraving CNC router machine. Both the manual and machine coexist.

In the video clip ( the CNC router is quickly finishing the cross on the headstone of a tombstone. The speed of the router is amazing. Laser etching CNC machines are also employed for tombstone engraving. This is an expensive method and only the wealthy can afford the laser etching. However, for a tombstone accuracy is not really required and speed is not a constraint for the departed. The router in the video clip is made by OMNI CNC, which is a reputed CNC router manufacturer from China. The stone CNC router is specially built with heavy duty frame work and solid rib welding that houses the high power spindle and advanced control system.

The table is also rigidly built and the heavy-duty construction allows different kinds of tombstones such as granite, marble, soapstone and other natural materials for engraving. THhe design input takes text and other designs such as the Catholic cross and the G-coded technology makes short work of the engraving in no time. The process is very fast and accurate.

Vectoring and Rastering via CNC Lasering

OMNI CNC are true technology partners to Signage industry entrepreneurs as they manufacture specialty laser machines that aids creativity in design and increased productivity.

The role of CNC Router manufacturers does not end just churning out machine after machine. Unless and until these manufacturers work as a silent but adjunct partner of the industry to which they are supplying the machine then only they can earn the badge of success. The CNC Router marketplace is intensively competitive. Manufacturers from America, Europe, and United Kingdom being pioneers have an inherent edge. China is the new powerhouse of CNC Router manufacturing. There are many manufacturers. One among them is making waves. This company is OMNI CNC Router manufacturers. They have passion for understanding to which they are supplying.

As an example, they supplied OMNI CNC Laser machine to FRF from Budapest in Europe. John Baksai the owner of FRF is another passionate and dedicated artisan who has created a niche in advertising display by specializing in light boxes, lighting and non-lighting display signage, LED advertising signage and other display production items like totem poles and neon tube manufacturing among others.

Vectoring and Rastering

Being a design-oriented company the accuracy of cutting LED signage as per original designs conceptualized becomes important in achieving the quality. FRF incorporate high quality standards in the materials like electronic equipment, LED light sources and enclosures in the designing and manufacture of LED advertising signage. The accuracy of design matching the concepts has taken FRF LED lighting signage to Romania, Austria, Belgium and Germany in Europe and to Hong Kong in China and Seoul in South Korea.

Vectoring and Rastering

OMNI CNC Routers with Laser cutting systems employ cutting-edge technology in vector cutting and raster engraving. Vector paths are clear defining tool paths for the CNC Router bits to accurately cut acrylic or other translucent material used in signage. The OMNI CNC laser machine performs vector cutting and raster engraving. Vector cutting is the process of cutting the outline shape of the image while raster engraving performs engraving functions as the tool bit glides along the substrate. The advantage of laser cutting is it can be used on several substrates. Vector means a line that allows designing LED lighting shapes as per image. There is calculation of geometry and other mathematical formula in computing the type of cutting.

Raster cutting is similar to printer simulation. The tool head of the Router moves back and forth creating pixilation of bit-maps Raster images are denoted in dpi (dots per inch). Incorporating a combination of vector imaging with raster graphics is the hallmark of FRF in Budapest that are faithfully executed by OMNI CNC Router Laser machine. The substrates like acrylic, leather, wood (MDF, plywood, soft woods) and other plastics like ABS, Polycarbonate, and Plastic Foam can all be cut using OMNI CNC Laser machine by vectoring.

Turning Hobbies to Business Idea with CNC Woodworking Routers

Prime examples of using CNC woodworking routers to turn a hobby of toy carving into a profitable business

Before electronics or electrons became a part of the mystique of civilization Man was using wood for building houses, as fuel for cooking and ultimately toys for children to play. So much so the carpentry world had its first taste of entrepreneurship in toy manufacturing as whittling became an art form. Carving intricate shapes in wood stemmed from carving basic shapes using a pocket knife. This led to the discovery of soft woods and the simple act of whittling turned into toy carving of dolls and figure and thereafter woodworking toys became a major industry. Read more

Relief Sculpture Engraving by CNC Router

A relief sculpture is a marvelous piece of art to witness. The detailing and expressive image evokes admiration and reverence when used in religion. The revered image appears lifelike adding the special holistic element when confronting spiritual needs. If looked closely the relief sculpture is a reverse of the process of sculpting. In sculpting, the image is carved to give a 3D likeness. In relief sculpture the background or field is removed so that the image is raised from a flat surface. Typically, a relief sculpture is more a 2D or 2.5 D image.

Acrylic sheets are also highly favored for both indoor and outdoor publicity material. Router bits can polish while cutting the edges. Polycarbonates have excellent weathering properties and are durable for outdoor signs. Sign foams are easily routable. Sign foams are made from polyethylene, polypropylene, ABS, polystyrene among others.

Corbel Engraving by CNC Router

Corbels have been around for centuries. Even before medieval times the use of corbels as supports was standard fitment in most homes. The poor used plain corbels to support ceiling beams. The rich would adorn the corbels to give a baroque look.

Corbel Engraving

Plain Corbel

From wood to metal was an obvious leap and some of the building renderings in the 11th and 12th century in Europe show balconies supported by large corbels. The picture of Juliet balconies (Juliet refers to Romeo courting Juliet (Shakespeare’s play). The fact is in the play Romeo would romance Juliet while she was at a window. However the name struck and has been in use ever since) is a fine example of the various uses of corbels both structurally and architecturally. Read more
