Model 920 - Metallurgical Grinder/Polisher

 

The Model 920 is the first in a new generation of multi-purpose lapping machines designed for accurately lapping and polishing a wide range of materials.

 

The 920 can be used as a standard metallurgical grinder/polisher utilizing abrasive papers, abrasive films, diamond discs, polishing cloths, etc. Or it can be used as a high precision free abrasive lapping machine for flat polishing of optical and semiconductor materials.

 

When used as a free abrasive lapping machine, the 910 can accommodate most SBT Lapping Fixtures for precise sample orientation and maximum flatness. The precision fixtures and the self-truing lap ensure samples of the highest quality. In addition to flat lapping, SBT offer 2 fixtures for polishing oriented crystals. The crystals can be oriented and subsequently polished while maintaining their orientation.

 

The 920 is also available with two optional workstations. These independently controlled workstations rotate SBT polishing fixtures automatically thereby simplifying the polishing process and minimizing operator supervision. The 920 is ideal for high precision polishing in both R & D and production environments.
