WATERJET CUTTING MACHINES |
| |
DWJ FLYING-ARM STRUCTURE MODEL |
 |
|
| |
THEORY OF WATERJET CUTTING : Waterjet machine usescold supersonic abrasive erosion to cut almost any materials both metals and nonmetals. The highly pressurized water stream is forced through a tiny area which carries abrasive garnet to erode away the material.

ADVANTAGES OF WATERJET TECHNOLOGY
|
|
| |
| |
> |
Cold cutting without thermal influences |
> |
Flexible processing of virtually all materials with consistent high quality. |
> |
Material-saving production due to reduced cutting width and the nesting of several parts on a single sheet. |
> |
Maximum degree of material utilization due to the smallest of part separation distances (partially free of burrs) and part–in-part production. |
> |
Tension-free processed parts due to minimal cutting force. |
> |
Environmentally friendly and clean production without poisonous gases. |
> |
Good access to the work area of the waterjet system |
> |
Optimization of the cutting parameters to meet individual requirements. |
> |
It is possible to identify the cut parts using waterjet engraving. |
> |
Close linking with the CAD/CAM programming system. |
> |
High material savings due to narrow bridges or ribs |
> |
No tool manufacturing and tool storage cost. |
> |
High productivity through multi head cutting systems and multilayer cutting. |
> |
High –performance drive system, which permits high-precision production of parts as well as the highest of processing speeds. |
> |
The combined production using waterjet cutting machines and milling centers guarantees economical processing. The parts can be prefabricated and nested and only high precision areas are post worked. |
> |
Fast setup and rapid programming. |
> |
Minimal requirement of fixture. |
