Nature can be gentle such as soft sea breeze or it can be abrasive such as water dripping on a stone. Did you read that right? Water is an abrasive material? If you walk near the river you will find stone formation that has been shaped by water flowing over it. Although it has taken a number of years the abrasive quality of water has eroded the minerals in the stone and created fantastic shapes and textures. This is the principle behind water jet cutting machine. Pressurized water is the source of the cutting force. The original commercial application waterjet cutting machine was developed as far back as 1971. At that time it was not possible to cut hard materials such as ceramic and stone with waterjet. Thus paper, textiles and sensitive material were the initial materials. In the 80s hard abrasives were mixed with the water that allowed materials such as stone and ceramics to be cut with water under sustained pressure.

Advantages of Waterjet Cutting Machine

It is known as a mechanical method of cutting. The water jet provides the energy. Abrasives in the waterjet provide the erosion action. The movement of the waterjet that causes micro erosion provides the force. The cutting water also acts as a cooling material cooling the cutting edge. This principle provides high quality and precision method.

China’s leading CNC Router manufacturer and exporter OMNITECH manufactures state-of-the-art OMNI –WAMIT waterjet cutting machine. It can cut several materials such as carbon-fiber reinforced plastics, carbon steel, stainless steeland other soft metals suchas brass, aluminum and copper. For cutting stone and ceramics it is ideal. It is mostly used in the production of kitchen sink countertops. High pressure pumps in the waterjet cutting system can accurately profile radius and other bends in stone materials such as marble, granite, travertine, limestone, onyx, soapstone, slate, and quartzite. The pumps are a mix of intensifier pumps and variable displacement pump that can achieve output pressures of over 6000 bar. The flow rate is adjustable Vis needle valves that are pneumatically controlled depending on the quality of the stone.
