CNC Turning Machining Pilot Punches

Custom CNC Turning Parts – Pilot Punches Overview
Funtion: the metal punches play a core positioning role in the working process, and their acuracy directly affects mold alignment efficiency and product yield.

Customer Pain Points:
1. Insufficient Guiding Accuracy: The total runout tolerance of the elliptical head is ＞0.02mm, resulting in positioning deviation.
2. Wear Issue: The head is easy to wear during use and needs to be replaced every 8 months on average, increasing downtime costs by 30%.

Solutions:
* Precision Machining Process: Precision CNC turning and precision grinding are used to control the key dimension tolerance of the head to ±0.005mm, and total runout to ≤0.01mm.
* Material Strengthening Solution: Use high-carbon high-chromium tool steel, through vacuum hardening and triple tempering, achieving a stable hardness of HRC60±1.

Results:
The guiding accuracy qualification rate of the punches is 100%, the service life is extended to 18 months, and overall customer costs are reduced by 22%.

We provide a full range of high-quality punches, mold and die components for custom metal stamping dies and precision molds, supporting non-standard customization.
