General Information

The demands on modern automotive engine and gearbox producers continue to increase. The additional requirements create capacity bottlenecks and an increased demand for more efficient grinding solutions. TYROLIT faces this challenge in external cylindrical grinding with a new generation of vitrified bonded CBN high performance grinding tools.

After intensive research, TYROLIT has succeeded in developing GENIS, a new bond system that makes it possible to guarantee optimal wetting of the CBN grain even with the lowest levels of bond content. Through careful choice of the composition of the bond components, the crystallization is specifically controlled under selected firing conditions. This makes it possible to achieve porous structures with high mechanical strength that exhibit maximum resistance to the effects of cooling lubricants.

Insufficient wetting of the CBN grains


Optimum wetting of the CBN grains


The cool grinding specifications of the GENIS high-performance tools allow a reduction of the grinding forces, and make efficient use of the CBN grain. Decreasing grinding forces are confirmed in practice with a wide range of application possibilities, through minimum tool wear and maximum profile retention.

Further product and user benefits:
  • New high-performance CBN grain qualities
  • Optimized chip clearance (porosity)
  • High bond strength
  • Optimal resistance to cooling lubricants
  • High thermal resistance
  • Customer-specific solutions
  • High process reliability
  • Optimal profile retention
  • Extended tool life
  • High cutting speeds
  • Maximum breaking strength
  • Optimal transport of cooling lubricants
Neutral Zone:


On request CBN grinding tools in the Genis product line can be produced with a neutral zone.  The benefit of a neutral zone is to allow the complete utilization of the CBN layer.


High-performance grinding tools also place higher demands on the dressing tools.  As a system provider, Radiac offers you a complete selection of rotating diamond dressing tools for these applications.
