Reversing rotation of angle grinder, would you? the standard rotation is always trying to tighten the wheel or cup, reverse rotation would do the opposite, it might be worse to have cutting wheels flying at your head instead of just sparks my preference is to have the grinder alwayd pulling INTO the work, i see guys having the wheel working against the grinders natural direction it'll bind up the wheel and somtimes shatter it...
Centerless Grinding In centerless grinding, the workpiece is held between two grinding wheels, rotating in the same direction at different speedsOne grinding wheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward This wheel usually performs the grinding action by having a higher linear speed than the workpiece at the point of contact...
