Ceramic Grinding With Self-Sharpening Diamond Wheels Subjected To Whee

The sharpness of resin-bonded diamond wheels was observed to increase 20-fold when the wheels were subjected to normal-force intensities of 30 to 50 N/MM. Once briefly subjected to those levels, the wheel would cut 15 to 20 times faster than the as-dressed wheel at moderate (lower) force levels. The resin bond wears very rapidly at the high force intensities, causing wheel-regenerative chatter to occur. Accordingly, the chatter-free grind time (CFGT) is short at the high force level.
