Fabrication by stamping or lasering for a variety of abrasive formats.

Shaping by high-performance stamping

Our abrasives are shaped using cutting blades and a yoke-type punch. High-performance punching machines are used to make simpler formats. These machines use precision tools with carbide dies which allow multiple formats to be punched simultaneously during each stroke. This places high demands on the accuracy of the tool and the punching machine.

Shaping using laser technology

The application of laser technology during abrasives manufacturing makes it possible to manufacture abrasive discs with very small holes and a large number of holes per disc. Today, this technology is used especially in the manufacture of multi-hole abrasive discs. The hole pattern of the FiboTec discs provides improved dust extraction, significantly reduced clogging and longer service life for the abrasive materials.
