Machine detail description

Multi-cut function is necessary for reaching high surface roughness during wire cut edm machine job, general speaking, the first time cut is fast and for getting the approximate dimensions. The second time cutting is for getting high accuracy, while the third time cutting is for getting high surface roughness. 

We are glad to say our A series wire cut edm machine is one of the good choice machine for high roughness requirement. The best accuracy is +/-0.0075mm, while the best surface roughness is ra0.8. 

The Parameter selection Plays a decisive role in multiple cutting working. Large pulse is needed for reaching a high cutting speed for the first time cutting. While the second time and third time cutting need a precision machining parameter, further more, the steady wire running system also play a decisive role. Any slight shaking may lead to poor effect. We have made several modification to our wire running system in our long time history.  

Our wire cut edm machine used molybdenum wire instead of brass. Even though molybdenum is a kind of high strength metal, the tension is not steady when machine is working at a high speed. The high temperature discharge causes the deformation to the wire.  In consideration of this, installing a wire leading device to wire running system will be necessary. 

Our machine configure with upper and lower dual wires tightening device, achieving consistence of constant tension for upper and lower wires.
