Product Specification

Available shape:

Two types of Vitrified bond CBN wheel for Inner grinding available:
wheel with shaft
wheel without shaft.
The Min. OD can be 3mm (0.118″)


Highly accurate and highly efficient
High grade abrasive grits and bonding powder
Perfect dressing ability in controlling surface finish and grinding efficiency


E-Grind Vitrified CBN inner grinding wheel are widely used for grooving of vane pump rotors and synchromesh ball-joints etc, as well as for forming injection parts.
The CBN physical properties (hardness, abrasion and high temperature resistance ) in connection with vitrified bond properties (hardness, brittleness, porosity structure) allow to machine a workpiece more aggressive with a great capacity and to achieve a high grinding productivity.

Working Condition



For grooving of Camshaft, crankshaft, injection needle, turbo parts, compressor parts, bearing, bearing, ball joints, motor parts, rocker arm…
