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