Connector Stamping Punch | Tungsten Carbide Precision Tooling

Precision-Ground Tungsten Carbide Punch for Connector Tooling

In connector stamping, small geometric details can make a significant difference to tooling performance.

This custom tungsten carbide punch features a narrow working end and carefully controlled transition geometry. Its design calls for more than dimensional accuracy alone. Surface finish, profile definition and the continuity of transition radii are also important considerations during manufacturing.

At Hepha Precision, we focus on Profile Grinding (PG) for precision punches, die inserts and other critical tooling components used in demanding stamping applications.

Smooth Transition Radii and Controlled Profiles

The transition between different profile sections is an important feature of a precision punch.

Poorly controlled transitions, unintended sharp edges or variations in the specified radius may affect the working geometry. Where the drawing calls for defined radii, Profile Grinding can help achieve a controlled transition between adjacent profile features.

Surface Finish for Precision Stamping Punches

Surface finish is another important consideration in precision tooling.

A suitable finishing process can help reduce grinding marks and improve the surface condition of critical working areas. For stamping punches, the required finish should be considered alongside the component geometry, material and application.

Profile Grinding provides a controlled finishing approach for selected profile features where surface condition and dimensional accuracy must be considered together.

Actual surface roughness requirements, including Ra values, should be defined and verified against the drawing or agreed inspection criteria.

Tungsten Carbide Machining for Demanding Tooling Applications

Tungsten carbide is widely used in tooling applications that require high hardness and wear resistance. However, its hardness and brittleness also require careful process selection, particularly when machining narrow features, small radii and detailed profiles.

At Hepha Precision, the manufacturing route is selected according to the component drawing and material requirements. Depending on the geometry, supporting processes may include:

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

The aim is to achieve the specified geometry and surface condition while managing the risks associated with machining small and delicate features.
