Metallographic Specimen Grinding Polishing Machine

1. function

The pre-grinding of the specimen is an indispensable process before its polishing in the preparation of the specimen. The pre-grinding enhances greatly the efficiency of the specimen preparation. M-2 metallographic specimen pre-grinding machine isthe result of a large-scale research work and the wisdom of the designers as well as the suggestions of the users.This machine has fiberglass shell, uses standard stainless steels, which greatly enhances the performance of the machine.

2. Working principle

The working principle of YM-1 Pre-grinder is as follows: clear water provided by a water tube flows into the rotating lap and the abrasive paper flowing over the water throws the water out of the lap as the result of the excentric force of the rotating lap forming a vacuum space before the atmospheric reassure presses the abrasive paper on the lap tightly. Now it is time to operate the pre-grinding. When the lap stops rotating, the work is done and abrasive paper can be easily taken off.
