3M™ Vitrified Grinding Wheels 33VC are our vitrified bonded grinding wheels with special white aluminium oxide grains and a green bonding system for conventional precision grinding operations. For outer diameter (OD) plunge grinding and creep feed grinding of turbine fir-tree roots, use 3M™ Vitrified Grinding Wheels - 33VC. Our vitrified bonded grinding wheels feature special white aluminium oxide grains providing low friability and high wear resistance. Their durable green bonding system makes them an ideal solution for precision grinding. These grinding wheels are durable and provide a longer lifetime than standard white Al2 O3 grains. They’re more specifically used for grinding non-alloyed or low alloyed non-hardened steels, or alloyed steels, hardened up to 60-63 HRc. They also provide high performance grinding for cast iron, or stainless steel materials.
