EDM wire cutting is a processing technology for injection molds. It can control and adjust the size of workpieces. Reasonable EDM wire cutting process can effectively ensure the quality of workpieces and the performance of molds. Among them, the analysis and review of drawings is an important step, which is the key to the quality of workpiece processing and comprehensive technical indicators. The first thing to do is to pick out the workpieces that cannot be processed or difficult to process. What are they?

Injection mold

1. For workpieces with relatively high surface roughness and dimensional accuracy, workpieces that cannot be manually ground after cutting must be picked out as soon as possible

2. Workpieces with narrow gaps smaller than the electrode wire diameter plus the discharge gap, and rounded workpieces formed by the discharge gap of the electrode dead plate derrick are not allowed at the inner corners of the graphics

3. Non-conductive materials and parts with thickness exceeding the span of the wire rack have adverse effects on EDM wire cutting.

4. Workpieces with processing length exceeding the effective stroke length of the xy support class and particularly high precision requirements

Under the conditions of wire cutting processing technology, the surface roughness, dimensional accuracy, workpiece thickness and material should be carefully considered.
