Selection table of polishing grinding blocks
|Workpiece Processing Requirements||Selection of Polishing Grinding Block|
|Commonly||Deburring, flying edge,
Oxide rust spot and rough throwing
|Abrasive Particle Size 100||Corundum abrasives|
|Higher||Deburring, scaling, chamfering,
rough and medium throwing
|The grinding effect between
150~W63 is better.
|High||Fine grinding, polishing
and surface finishing
|The abrasive particle size W63 has better
effect of fine grinding.
|Deburring, flying edge, oxide rust spot,
|Selection principle||1. Choose grinding tools with finer grain size in finishing and grinding tools with coarser grain size in roughing.
2. The Abrasives should not be too large when processing small parts and too small when processing large parts.
3. The hardness of abrasive tools is selected according to the turning rate and abrasion.
4. When processing the parts with holes and grooves, the abrasives are 1.5 times larger than the holes and grooves, and the small abrasives are 1/3 smaller than the holes and grooves.
5. The ratio of abrasive tool to workpiece is 2:1-5:1. Rough machining is ahead of time and finish machining is behind time.
