Product Description  
3M Vitrified Grinding Wheels 91VB are our vitrified bonded wheels for optimising roughing and finishing process steps while grinding gear parts.

Get high performance capability, less dressing and thermal damage, and higher productivity with 3M Vitrified Grinding Wheels - 91VB

These vitrified bonded wheels combine the advantages of two key technologies, 3M Cubitron II precision shaped grain and our NA series grits, resulting in high performance roughing and finishing grinding steps for gear parts.

Requiring lower dressing time and providing longer intervals between dressing, they help to significantly decrease related dressing costs, cycle times during both roughing and the last step of the threaded gear parts finishing process, which can help to save substantial costs. They consistently perform well in terms of ffα values (profile errors) and provide good surface quality with very low Rz and Ra values.

3M 91NDA - 91VB grinding wheels are ideal for assisting with machine balancing issues.

Extra Details

  • Balances machine problems and can be used universally
  • Delivers high performance and durability while rough grinding
  • Designed for crankshaft grinding
  • High gear quality – profile error ffα < 2μm without any issues, surface roughness Rz < 2,5μm
  • High process stability and constant quality for critical workpieces
  • Ideal self-sharpening and early chip formation
  • Lower dressing cost thanks to higher dressing interval
  • Lower temperature during grinding avoids thermal damages on the workpieces
  • Powered by a special mix of alumina and ceramic grain
  • Reduces grinding time by more than 20 % thanks to higher feed rate in roughing and finishing
