It is mostly used GC stick for the shape and diameter limit of wheel. Two grade tough mesh size is more effective than that of wheel's diamond grit size. Truing and Dressing is quite necessary process for the making of wheels. It is better way to truing and dressing process after fixing the wheels at the using machine.

ex) Use GC grinding wheel 150 ~ 170 when grit size of Diamond wheel is 200

After truing process, as diamond and CBN grit is inside of bond, so grinding performance is quite low. So dressing process is necessary for the exposure of diamond/CBN grit definitely, through scratching the Bond into particles. That is same effective work, such as setting the teeth of a saw and sharpenning a blade of knife on the stone. (For example, WA 230-270# grit is suitable for the wheel's grit 200 )

( NOTICE : Wheel's speed should be lower during the dressing as far as you can do.) [About 200~400 rpm]
