3M™ 7100227981 Vitrified Grinding Wheel, 400 mm Dia x 1.26 in THK, 5 in Hole, 240 Grit

3M™, 7100227981, Vitrified Grinding Wheel, 400 mm Wheel Diameter, 1.26 in Wheel, 5 in Center Hole, 240 Grit

• High performance while rough grinding, less dressing and thermal damages, shorter cycle, higher productivity
• Delivers durability and efficiency with cubitron, II precision shaped grains
• Ideal self-sharpening and early chip formation
• High surface and profile quality, with absence of chips cold welding
• Powered by a special mix of alumina and ceramic grain
• Designed for crankshaft grinding
• Lower temperature during grinding avoids thermal damages on the workpieces
• High gear quality profile error ffα less than 2 μm without any issues, surface roughness Rz less than 2,5 μm
• Reduces grinding time by more than 20 % thanks to higher feed rate in roughing and finishing
• Lower dressing cost thanks to higher dressing interval
• High process stability and constant quality for critical workpieces
• Balances machine problems and can be used universally
