CNC Parts - Toothed Punch

The custom metal punch is used to form the workpiece, forming a specific toothed structure to ensure that the product meets the shape and dimensional accuracy required by the design.

Pain Point Analysis:
The toothed punch is prone to wear during continuous operation, which affects iths service life and the dimensional consistency of the processed product.

Solution:
1. Material Upgrade: Use high wear-resistant powder metallurgy steel PM60.
2. Heat Treatment Process: Through vacuum quenching + deep cryogenic treatment, the hardness is stably controlled at HRC66-68.
3. Precision Machining: Use the Japanese Seibu brand wire cutting CNC machining to ensure the profile accuracy of ±0.003mm.
4. Surface strengthening: Apply titanium carbonitride (TiCN) coating to reduce the friction coefficient.

Result:
The service life is increased by 57%, the product yield is raised to 99.2%, and the downtime caused by part replacements is reduced.
