The KOIKEJET® abrasive water jet machine is a high-pressure waterjet machine that utilizes straight water cutting or abrasive waterjet cutting to cut several types of material. The KOIKEJET® is a heavy-duty precision, ground ball screw designed system for maximum precision and rigidity. The KOIKEJET® is built to the most stringent standards in the machine tool industry.

The KOIKEJET® using the water jet high-pressure cutting process to cut material thicknesses from gauge up to 8".
The KOIKEJET® will cut material such as Aluminum, Armor Plate, Brass, Carpet, Copper, Glass, Granite, Leather, Marble, Mild Steel, Plastic, Stainless Steel, Stone, Tile, Titanium...

Waterjet machining is achieved by forcing a large volume of water under high pressure through a small orifice in the cutting nozzle.  The accelerated steam of water leaving the nozzle impacts the material and starts the cutting process.  Kerf from the accelerated stream of water is extremely narrow.  This pressure is then concentrated in a small area on the material which starts to erode the material.  Softer materials can be cut with water pressure.  Harder materials require the use of an abrasive feed system, such as metal cutting.  The abrasive is introduced into the high pressure water stream, which then starts the erosion of the harder materials.  Although waterjet machining is the slowest cutting process, there are definite advantages that outweigh its' pace:


  • No Heat-Affected Zone  
  • No Mechanical Stresses  
  • Very Narrow Kerf  
  • No need for Secondary Operations  
  • Smooth Surface  
  • Can Cut Various Materials  
  • Can Process Extremely Detailed Parts  
  • Minimal loss of material  
  • Environmentally Friendly
