Reasons for the weak speed of stone polishing machine

For polishing machines, rotational speed and friction (polishing) force are the conditions for the matching of two concepts:
1. High speed, low friction, conversely speaking, low friction, fast speed
2. Slow speed and high friction, and vice versa;
So the key to solving this problem is to first determine how much force is needed to shift and change speed during operation, adjust the appropriate speed to achieve normal polishing, otherwise the internal gears will need to be replaced, and small polishing machines may have fixed gears that cannot change speed.
