Abrasive Water Jet Cutting
Our waterjet cutting has been one of our fastest growing department.  The process is heat and gaseous free and allows for accurate cutting over a wide range of materials and applications. With an adjustable tilting head the water jet can cut square edges up to 100 mm thick to tolerances of +- 0.1 mm.

Materials suitable for Water jet cutting include:

  • Aluminium, Titanium & Alloys of all types
  • Stainless Steels & Hardened Tool Steel
  • Brass & Copper
  • Plastics, Ceramics, Stone & Glass
  • Mild Carbon Steels
Abrasive jets have been in use in industry since 1982. Waterjets, the precursor to abrasive jets, have been in use since 1970. Water cutting abrasive jets are used in many industries, including the automobile, aerospace, and glass industries, to create precision parts from hard to cut materials.

A water cutting abrasive jet uses water that is pressurized up to 55,000 pounds per square inch (3800 bar) and driven through a small sapphire orifice at 2500 feet per second (800 m/s), or about two and a half times the speed of sound. Garnet abrasive is then pulled into this high-speed stream of water in a long carbide mixing tube. A stream of abrasive-laden water moving at 1000 feet per second (300 m/s) exits the carbide tube. The abrasive strikes the material and cuts the material precisely.

Advantages of Abrasive Water Cutting Jets
Abrasive jets hold a number of advantages over other machining methods:

Wide Range of Materials
Abrasive waterjets can machine a wide range of thicknesses and materials, including metals, plastics, glass, and ceramics.

Quality Finish
Materials machined by the abrasive jet have a smooth, satin-like finish, similar to a fine sandblasted finish.

No Heat in Machining Process
Abrasive jets abrade material at room temperatures. As a result, there are no heat-affected areas or structural changes in materials with low melting points.

Environmentally friendly
Abrasive water cutting jets use garnet as an abrasive. Garnet is a reddish natural crystal, with a Mohs hardness of 6.5 to 7.5. No noxious gases or liquids are used in abrasive jet machining, nor are there any oils used in the machining process.

No Tool Changing
A wide range of conventional processes can be performed with this single tool including,drilling, sawing, broaching, gear cutting, profile milling, punching, slitting, spline cutting & blanking.

Minimal Burr
No heavy burrs are produced by the abrasive jet process. Parts can usually be used directly without deburring. What OMAX brings to you

The entire path and speed of the abrasive jet is carefully calculated, taking into account the material to be machined and the shape of the part, at a resolution of over 2,000 points per inch (790 points per cm), before the cut is made. This allows the speed of the abrasive jet nozzle to be precisely controlled for smooth, even, machining.


Fast Cost-Effective Machining
Special computer algorithms automatically optimize the tool path with advanced corner compensation, corner passing, and other improvements. A highly sophisticated cutting model allows for parts that are both faster to cut and more precise.
