当车轮承受30到50 N/MM的法向力强度时，观察到树脂粘结金刚石车轮的锋利度增加了20倍。一旦短暂受到这些水平的影响，在中等（较低）力水平下，车轮的切割速度将比修整后的车轮快15到20倍。在较高的力强度下，树脂粘合剂磨损非常迅速，导致车轮再生颤振。因此，在较高的力水平下，无颤振研磨时间（CFGT）较短。

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.
