Punzón de rectificado PG para matrices de estampación progresiva

PG Grinding-Accuracy Reach ±0.001mm

PG Grinding Punch is designed for demanding stamping and tooling applications. In these applications, dimensional accuracy and profile consistency are critical. PG is a technology using optical profile grinding. It enables superior control of sharp edges, complex contours, and micro features, ensuring stable performance in precision dies.

Technical Capabilities

Key point: PG excels at small, delicate, or thin-walled parts without deformation.

Clean and Accurate Profile Geometry, Precise Radius (R) Control and Smooth Surface Finish

Every PG grinding punch is clean and accurate profile geometry, precise radius (R) control, and smooth surface finish. They are important for reducing wear, improving punch life, and ensuring consistent cutting quality during high-volume stamping operations. The PG process is especially suitable for following punches:

PG grinding process support a wide range of materials. For reference, Belows are the most commonly used materials.

In a word, both soft and hardened conditions are available. And it just depending on the design and application requirements. To meet the functional needs of each specific punch design, PG Grinding controls surface condition and edge quality, profile geometry.

During the manufacturing process, we apply dimensional inspection and process control. This step ensure consistency and repeatability, making sure our PG grinding punch suitables for both prototype development and repeat production. Hepha Precision support Custom designs, small batch orders, and stable lead times. Therefore, technical drawings are welcome for evaluation. What’s more, each project is handled with a tooling-oriented approach to ensure reliable performance in actual stamping applications.
