Application of medium wire cutting

Dec. 15, 2020

WEDM has opened up a new technological way for the trial production of new products, precision parts processing and mold manufacturing, which is mainly applicable to the following aspects.

 

(1) Processing mould

 

It is suitable for processing various shapes of stamping dies. The punch, punch fixed plate, die and discharge plate can be cut only once by adjusting the gap compensation. Die fit clearance and machining accuracy can meet the requirements. In addition, it can also process extrusion die, powder metallurgy die, bending die, plastic compression die and other commonly taper mold.

 

(2) Machining electrodes for EDM

 

In general, the electrode used for piercing machining, the electrode for machining with taper cavity, and electrode materials such as copper tungsten, silver tungsten alloy, etc. are particularly economical and suitable for machining micro and complex electrodes.

 

(3) Machining parts

 

In the trial production of new products, parts can be cut directly from the blank by WEDM, such as trial cutting the stator and rotor cores of special micromotor silicon steel sheet. The manufacturing cycle can be greatly shortened and the cost can be reduced because there is no need to make another mold. In addition, it is convenient to modify the design and change the processing program. When processing thin pieces, multiple pieces can be stacked together. In the aspect of parts manufacturing, it can be used to process parts with more varieties and less quantity, parts with special difficult to machine materials, material test samples, various types of holes, special gear cams, templates and forming tools. At the same time, it can also be used for micro machining, special-shaped groove and narrow slot machining of artificial standard defects.
