Long-Profile Carbide Punch for Precision Stamping Dies

Precision Grinding for Long, Narrow Punch Profiles

This long-profile carbide punch is designed for precision stamping tooling where profile geometry and dimensional consistency are critical.

Manufactured from KD20 carbide, the component features an elongated, narrow profile that requires careful machining and finishing. For this type of tooling component, achieving the nominal dimensions is only part of the challenge. Maintaining profile accuracy along the working length is equally important.

At Hepha Precision, we use Profile Grinding (PG) as a key finishing process for precision punches and other critical stamping die components.

Key Manufacturing Considerations

1. Profile accuracy along the working length

Long, narrow profiles require consistent dimensional control from one end to the other. Local deviations can affect the working geometry and the performance of the tooling.

2. Controlled finishing of critical features

Profile Grinding carefully finished the required contour according to the component drawing, including critical edges and transition areas where applicable.

3. Material-specific machining

KD20 carbide requires suitable machining strategies and careful process control. We select the manufacturing route according to the material, geometry, tolerance requirements and finishing allowance.

4. Repeatable quality

For replacement punches and repeat orders, consistency between components matters as much as the dimensions of an individual part. Inspection requirements should be defined against the drawing and the customer’s application.

Our Manufacturing Capabilities

Hepha Precision focuses on precision tooling components for stamping and connector applications.

Our supporting processes include:

• Profile Grinding (PG) for precision contours
• Wire EDM for complex profiles and pre-machining
• Precision Sinker EDM for suitable detailed features
• Surface Grinding for flat surfaces and dimensional finishing

The machining route is determined by the component’s geometry, material and tolerance requirements. Wire EDM and other processes can be combined with Profile Grinding when additional profile finishing or dimensional control is required.

Custom Carbide Punches for Stamping Tooling

製造 customized punches, die inserts and other non-standard precision tooling components according to customer drawings.

Whether you need a new component, a replacement punch or support for a demanding profile, we can review the drawing and discuss a suitable manufacturing approach.
