The Σ (sigma) Wheel is the ultimate tool for grinding parts susceptible to grinding burnings (parts such as crank shaft shoulders that have little exposure to coolant during grinding).
- Noritake’s proprietary CBN wheel technology can lower grinding resistance (and power consumption).
- Grinding burnings can be significantly reduced and the lifespan of the grinding wheel as well as grinding quality can also be improved.
- Crank shaft grinding, machining processes that easily produce grinding burnings
