Automatic metallographic polishing apparatus

摘要

The metallographic sample preparation device comprises a polishing post (8) located next to a vertical magazine (9) supporting polishing plates. Gripping and transport means (10) enable the plate to be transferred between the magazine and the polishing post. There is a pre-polishing post (6) and a cleaning post (7) located between the polishing and pre-polishing posts. A samples door (11) enables the transfer of the samples between the different posts by a rotational movement around a first rotational axis (s8). Control means engage the gripping means for transferring the plates between the magazine and the polishing post during which the samples door is located above the cleaning post.
