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.
