PUNCH GRINDER / PUNCH FORMER

[ Surface Grinder with Punch Grinding Attachment, Surface Grinding ]

A punch grinding machine is a specialized device used to grind and maintain punches for stamping molds. It quickly restores dull punches, improves product precision and production efficiency, and extends mold lifespan.

Applications:

  • Grinding worn or dull punches
  • Adjusting punch size and angle
  • Enhancing punching accuracy
  • Extending mold service life

Advantages of a Punch Grinding Machine

  • High-precision grinding to keep punches sharp
  • Easy to operate, saving maintenance time
  • Suitable for various punch shapes
  • Improves production efficiency and reduces costs

Punch Former: The Fixture for High-Precision Punch Creation. The Punch Former is not a grinder itself, but a critical, high-precision indexing and clamping tool. It is used in conjunction with a surface grinder to create complex or custom punch profiles with exceptional accuracy.

Key Applications of a Punch Former:

  • New Punch Fabrication: Manufacturing brand-new, high-tolerance punches, core pins, and EDM electrodes. Complex Profile Grinding: Enables the precise grinding of intricate shapes, including concave/convex radii (R), complex multi-angles, and non-standard contours.
  • Wheel Dressing: Some models include an arm for accurately dressing the grinding wheel to a specific angle or radius. Advantages of a Punch Former Micro-Precision Forming: Achieves extremely high rotational and angular accuracy (often within a few arc seconds).
  • High Versatility: Its indexing mechanism allows for the creation of round, polygonal, and specialized custom punch forms. Superior Finish: Ensures the geometry is perfect, directly enhancing punching accuracy and the final product's quality.

In summary, the Punch Grinder is your solution for fast, routine maintenance, while the Punch Former is the essential high-precision accessory for manufacturing and defining complex tool geometries. Together, they are fundamental for achieving world-class precision in the mold and die industry.
