Portable Compact Punch and Die Sharpening Machine for Small Stamping Shops

This machine is specifically designed to surface grind and sharpen the faces of punches and dies used in punch presses. It restores tooling to its original geometry, ensuring clean cuts and extending the life of your tooling.

Yes. The grinder is equipped with dual stations or adaptable fixtures that allow for the precise sharpening of both the male punch (to restore its cutting edge) and the female die button (to clean up the slug ejection area).

The machine features precision-ground locking pins and adjustable guides. When the punch is placed against the guide pin (or located in the V-pin), it automatically presents the cutting angle (usually a slight concavity or flat) to the wheel, maintaining the factory-specified geometry and radial clearance.

We recommend removing only the minimum amount necessary to achieve a clean, sharp edge-typically between 0.1mm and 0.3mm (0.004'-0.012'). Aggressive cutting can generate heat and soften the tool steel (annealing), which drastically reduces tool life.

It is highly recommended. While small, intermittent cuts can be done dry with a proper vitrified wheel, using the built-in coolant system (or mist coolant) prevents heat buildup. This maintains the hardness of the high-speed steel or carbide tooling and provides a superior surface finish.
