Press Mold [Precision Mold Design and Parts Processing Examples] Improvement of Carbide Punch Lifespan

The milling processing technology for carbide materials has tripled the lifespan of punches! Here is a case study for a precision electronic component manufacturer.
When performing electrical discharge machining on carbide materials, microcracks due to thermal effects occur during processing. These cracks penetrate to a depth of about 20μm, so no matter how much you polish the surface, they remain.
These cracks can cause wear in punches that are subjected to strong loads.
In contrast, milling processing does not produce any microcracks at all. Milling tools can go down to R0.1, and the flexibility of the processing shape is very high.
[Case Overview]
- Customer Industry: Precision Electronic Component Manufacturer
- Inquiry: Wanted to improve the lifespan of carbide riveting punches
- Proposed Solution: Transitioning from electrical discharge machining to milling
- Technology Used: Milling processing technology for carbide materials
- Results: The lifespan of the punches has tripled.
