3M™ Cubitron™ II Vitrified Grinding Wheels 91VA are our vitrified bonded grinding wheels with 15% precision shaped grain, featuring geometrically defined cutting edges. They’re ideal for single rib profile grinding of gear parts.

For improved productivity and removal rates while reducing grinding passes, use 3M™ Cubitron™ II Vitrified Grinding Wheels - 91VA

Our vitrified bonded grinding wheels have a free cutting ability that helps to deliver high rates of material removal, increasing the in-feed and feed rate, and reducing the number of grinding passes. This results in substantial improvement in grinding cycle times and can help to reduce costs and increase overall production capacity without sacrificing quality.

Featuring 3M Cubitron™ II precision shaped grain (PSG) technology with self-sharpening triangular cutting edges, these grinding wheels meet high level surface finish requirements while maintaining a consistent quality level.

The abrasive has a cool grinding effect delivering lower thermal load on the workpiece, which reduces the risk of burning, even during demanding grinding conditions. Self-sharpening technology decreases the need for dressing, extending both diamond roller and conventional wheel lifetime, and improving the total cost of grinding operations.

Ideal for machines with a lower spindle power, due to the lower PSG concentration, they suit universal and versatile grinding needs for single rib gear parts' profile grinding operation. Use in combination with 3M™ Diamond Rotary Dresser 6HMI for optimal results.
