To improve cutting efficiency, it is not only necessary to avoid “drifting” phenomena, but also the abrasive and disc cutting grades. This post mainly explains when grinding, determine whether the abrasive material is maximally touching the friction paint surface. If some paints can use more than 2500 rpm under the right amount of abrasive and the appropriate downforce, there will be no "drifting" phenomenon during polishing, so this is a very efficient approach. In fact, many burnouts, throwing paints, and throwing off paints are all due to the phenomenon of “drifting”, resulting in accumulation of abrasives and aggravating the friction at certain points. The polishing machine has to overcome these The huge friction eventually conquered the paint's adhesion.
