Moresuperhard Vitrified Bonded CBN Wheels for Peel Grinding of Gear Shaft:
Moresuperhard provides new solutions for rough grinding using a peel grinding technique evolved from previous work. Due to the unique wheel composition, a new high-strength metal bond and innovative diamond qualities the
vitrified bonded CBN grinding wheels offer convincing performance. The process is carried out with an extremely low grinding noise level, wear is significantly reduced, whilst having improved surface quality and an especially high stock removal.
Features of Peel Grinding
— High-precision, high-efficiency
— Center-going, step-difference forming external cylindrical grinding
— The punches and needles are rough and finely ground at one time, and the finish is high
— With less frequent dressing in the case of vitrified CBN wheels or without dressing in the case of plated CBN wheels
