For grinding workshops looking to achieve outstanding performance while meeting high quality standards, 3M High Performance Vitrified Grinding Wheel 91VX is the solution you are looking for. By combining the unique assets of two technologies — 3M Precision-Shaped Grain and the upgraded 3M High Performance Vitrified Bond V470 — it provides a high stock removal rate capable of grinding parts without thermal damage and extremely precise profile geometry.Powered By Two Innovative Technologies 3M High Performance Vitrified Grinding Wheel 91VX combines two cutting-edge technologies: 3M High Performance Vitrified Bond V470 and 3M Precision-Shaped Grain. For the very first time, 3M Precision-Shaped Grain is being offered down to #180 size, which makes it suitable for addressing the finest quality requirements of the automotive industry — including the whole range of E-drive components. 3M High Performance Vitrified Grinding Wheels 91VX are also commonly used into powertrain transmission systems, turbines, cutting tools and bearing industries. Overall grinding performance remains stable and very repeatable despite extreme grinding conditions. Those are sustained to the narrowest deviation through the entire life of the wheel which makes it an ideal solution for demanding applications. Grinding performance and the wheel’s overall behavior remain very stable while grinding critical parts. 3M High Performance Vitrified Grinding Wheels 91VX deliver highly enhanced profile retention and form holding while risk of burning is drastically reduced thanks to its cool cutting properties. Its lower need for dressing allows more parts to be ground between each dressing interval, which notably boosts the durability of the 91VX Wheel, decreasing the overall cost per ground part.
