Super Long Life Vitrified-bond CBN Wheel “MEGA-LIFE WHEEL”

The MEGA-LIFE WHEEL is a completely new vitrified-bond CBN wheel with extended life. This extremely durable new wheel delivers high efficiency, high quality and long life, and is ideal for high-load grinding such as cam-lobe profile grinding and contour grinding that demands sustained wheel shape.

Features

This wheel delivers better performance than existing wheels thanks to a newly-developed wheel structure and the new “VML” bond, which offers high strength and good erosion.

  • Enables extreme improvements in dressing interval.
  • Advanced machining performance reduces occurrences of grinding breakage.

Applications

  • Cam-lobe profile grinding
  • Contour grinding
  • Cylindrical grinding
