CNC Parts - CNC Machining Hollow punch

The custom metal punch is used to create specific hollow shapes to meet design requirements.

Customer Pain Points:
1. Wear: The metal punch is repeatedly stamped during use, resulting in easy wear and a short service life.
2. Deformation: Under high loads, the punch for metal undergoes plastic deformation, causing deviations in stamping dimensions.

Solutions:
* Machining Process: Use CNC wire EDM (Wire Electrical Discharge Machining) to ensure both profile accuracy and surface roughness, while avoiding milling stress and improving wear resistance.
* Heat Treatment: Use DC53 material with vacuum hardening and triple tempering, stabilizing hardness at HRC 60-62 to enhance rigidity.

Final Results:
Punch life increased by 45%.
Stamping yield improved to 99.1%.
Overall production efficiency increased by 30%.
