Product Overview
Superfinishing Grinding Wheels for Bearing Raceways
This is a highly porous general-purpose super-finishing wheel that uses a new abrasive grain. Thanks to its excellent chip evacuation properties, it is resistant to clogging, offers superior cutting performance, and has a long service life.
Application
- Superfinishing of Bearing Raceways
Types of Adhesives
- Vitrified
Product Features
It delivers excellent performance at low speeds and with minimal vibration.
It breaks in more easily and is easier to use than ultra-fine-grain grinding wheels.
Compared to standard super-finishing grinding wheels, its service life is 5 to 30 times longer.
Product Lineup
- Abrasive Grain Size
- #2000 equivalent to #8000 equivalent
- Degree of bonding
- -150 to 100
- Compatible Sizes
- From □0.8 to □80
Comparison of Surface Conditions
Even machining operations that tended to cause welding CBN can be performed stably with an AFF grinding wheel, without any welding at all.
