Waterjet Cutting |
|
| Advantages of Abrasive Water 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 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: |
|
| 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. |
| |
» Fast 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. |
| |
» Precise machining |
| |
With proper tool setup, can hold dimensions closer than ±0.005" (±0.13 mm). |
| |
» Calculate then move |
| |
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. |
