Tungsten carbide punches details:

We are able to make the punches as per your drawings.

Utilizing five-axis simultaneous grinding and mirror polishing processes, the core precision indicators reach the high-end level of the industry:

Dimensional tolerance: Ultra-precision level ±0.001mm (higher precision can be customized as needed);

Roundness/concentricity: ≤0.003mm, radial runout ≤0.002mm;

Surface roughness: Ra≤0.05μm (mirror finish), reducing material adhesion and friction loss during the stamping process and ensuring the surface finish of the workpiece.
