💡 How do drive pulley ratios affect belt velocity on stationary grinders?
- Shift drive voltage to change RPM on the fly so the band moves fast enough for quick stock removal
- Swap contact wheels for different curves letting you handle everything from straight seams to rounded pipes
- Bolt the whole rig down firm so vibrations dont bounce around the concrete floor when you beat on tough metals
- Tighten tracking knobs once and forget it since proper alignment keeps abrasive strips centered all day long
