General Information

Overcome challenges with MIRA-ULTRA With its MIRA-ULTRA product line, Radiac/Tyrolit has set new industry standards. The high performance level of these worm grinding wheels is attributed to the newly developed Ultra bonding matrix together with the appropriate choice of grain and grain size.  The wheel design uses a porous structure which holds profile allowing for both an increase in grinding speeds/feeds as well as increased parts per dress.

Innovation

  • MIRA-ULTRA bond system
  • Highly porous wheel design
  • Increased profile retention
  • No sintered aluminium oxide for less wear on the dressing tool
  • Able to work up to 80 m/s

Precision pre-profiling reduces costs

Worm grinding wheels can be supplied unprofiled or precision pre-profiled with one or more starts. Pre-profiling is carried out by module and pressure angle; for special designs, the specific tooth geometry data provided by the customer may be used as well. Radiac/Tyrolit can also accommodate additional requirements, such as relief in the root of the worm grinding wheel to reduce dressing tool wear.
