Vitrified-bond CBN wheels supplied with an arbor for precision internal grinding of bearing components and other hardened ferrous workpieces. Wheel geometry, abrasive specification and operating conditions are confirmed for each application.
Designed for Precision Internal Grinding
- Vitrified-bond CBN abrasive rim
- Wheel supplied with an arbor for internal grinding setups
- Custom wheel diameter, width, bore and arbor geometry
- Application review for hardened bearing steel, HSS and suitable tool steels
Typical Applications
Bearing Components
Precision grinding of internal bearing features where dimensional control, form retention and a repeatable wheel specification are required.
Hardened Ferrous Parts
Internal grinding of appropriately hardened bearing steel, high-speed steel and selected tool-steel components after application review.
Custom Bore Grinding
Non-standard wheels and arbors matched to the bore geometry, stock allowance, surface requirement and grinding machine.
Specification Reference
| Item | Available / Required Information |
|---|---|
