Abrasives wear too quickly 1. Excessive pressure on disc during use
2. Incorrect abrasive grade or type.
3. Incorrect working speed.
4. Insufficient lubrication (water)
1. Use light/reduced pressure when working
2. Use correct abrasive grade or type: use coarse
abrasives for shaping and grinding, use fine
abrasives for sanding/prepping, use only polishing
abrasives for polishing. Use Diamond abrasives for
high-carbon metals or stones of 7+ Mohs scale.
3. Adjust speed for abrasive type & workpiece.
Ex: Use low speeds for hard stones and glass.
4. Lubricate abrasives or workpiece during process.
Ex: Diamond abrasives require lots of water when
working on hard stones. Trizact abrasives require
lots of water when working on glass.
Non-uniform surface finish
on workpiece
1. Workpiece held immobile too long
2. Abrasive did not fully contact the
desired area.
3. Incorrect working speed.
1. Move piece continuously under the abrasive to
change direction of grinding or polishing strokes.
2. Make sure abrasive contacts workpiece fully. To
locate the area, mark it with a permanent marker
(Sharpie) of contrasting color and work the surface
thoroughly. Marker will be erased where the
abrasive contacts the surface. This is desired.
3. Adjust speed based on abrasive & workpiece.
