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.

OPTIONAL ADD-ON FEATURES

 

DAE DISTANCE ADJUSTING SYSTEM

     
 

DAE is used for adjusting the distance between the nozzle and the work-piece automatically.DAE ensures high quality of the cutting surface and prevents the nozzles from breaking due to collision.

 
     
DAE DISTANCE ADJUSTING SYSTEM
     

DAADS-B AUTO ABRASIVE DELIVERY SYSTEM

     
 

DAADS-B has the capability of storing abrasive an delivery

 
     
 
 
     
 

DAADS-B has the capability of storing abrasive and delivers the abrasive to the bucket automatically. The design shows our continuous effort improve efficiency and reduce labor requirement.

 
 

 

 
  -High sensitive sensor gives indication to operator when the hopper is empty.
-With 170 liters abrasive storage capacity, system can supply abrasive for continuous operation of 500 to 800 minutes.
 
     

DOUBLE CUTTING HEAD

     
 
 
     
 

With the double cutting head the waterjet will double the cutting efficiency. Which results into saving of time, increase the production and decrease the production cost.

New-cam is especially designed for WATERJET machine. It runs on WINDOWS XP system and has many advanced functions such as auto-cutting in and out, auto nesting, simulating the track before working, calculating time and the cost.

 
     

DCM ROBOT WATERJET CUTTING SYSTEM

 
THE BEST ALTERNATIVE FOR CUTTING THE INTERIOR OF AN AUTOMOBILE
 
 
  DCM can cut an automobile interior in any angle and separate scraps automatically. The system is efficient and flexible. It can process different types of the work-pieces by changing the program  
     
 

-DCM system components: Robot arm, UHP pump, Water softener, Work –piece positioning system, Scrap separation system, Safety system and control system.

-UP- 20MN Robot (YASKAWA), Cutting area: 2700mm ×1800mm×200mm, a larger work-piece can be processed using 2 or more robots at the same time.

-One robot can process two work-pieces alternately

-Pure waterjet cutting or abrasive waterjet cutting can be chosen according to the material
-Perfect safety system make the work safe
-Easy to operate and maintain.

 
     

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.
