Working principle
Stepwise grinding & polishing
Each step removes the damage left by the previous one, rotating the direction by 90°, until only negligible relief remains and the structure is not smeared.
- P240 → P2000
- 90° rotation
- Diamond to mirror
Product overview
The MPD-1A has sealed water inlet and outlet arrangements that separate flowing water from the circuit board. A large, deep preparation chamber helps contain coolant and polishing-fluid splashes and accommodates larger specimens. Its constant-torque spindle offers continuously variable speed from 50 to 1500 rpm. Coarse grinding, fine grinding and polishing are supported through changes of abrasive paper and polishing disc for metals, ceramics, rocks and electronic components.
