Grinding Hardness Line

Oct 01, 2007 Since the machined surface is hardened by hard turning and grinding at gentle machining conditions, it is a natural question to ask if the increased hardness can be directly measured in subsurface. Nanoindentation provides a feasible approach for precision machined surface [Guo and Warren, 2004] to avoid the potential “edge effect” since

    Dec 15, 2000 In a grinding wheel, the abrasive performs the same function as the teeth in a saw. But unlike a saw, which has teeth only on its edge, the grinding wheel has abrasive grains distributed throughout the wheel. Thousands of these hard, tough grains move against the workpiece to cut away tiny chips of material

    Understanding Grinding Wheel Hardness - Sparky Abrasives

    The amount of abrasive bond in the grinding wheel determines its grade or hardness. Hardness is dependent on the grit type, the material being ground, the amount of stock removed, and a number of other factors. Hardness is rated from A-Z, with “A” being the weakest bond and “Z” being the strongest. Harder or stronger bonds in grinding wheels, in essence, means that the abrasive grains are very
