M-2 Metal Sample Pre-Grinding Machine portable hand polishing machine
Application:
This machine is a wet grinder; it makes use of different sizes of sand paper, carries out the grinding on the sample of various metals and the alloy.
Using the pregrinding machine, beside the replacement of manual sample by mechanical polishing can improve efficiency, it can also completely remove the traces of plastic deformation and surface in the process of specimen cutting, after further polishing, and it will have the micro-measurement of the organization.
Structural characteristics outlined:
In the process of working, the pre-grinding machine can inject cooling water into the rotating millstone through the rotating-water; the sandpaper can stick to the millstone through the power of atmospheric pressure, so there is no need for bonded or clamping sandpaper.
This machine is equipped with beautiful and practical fiberglass shell, the full use of stainless steel standard parts, the body will never rust, and thereby it greatly enhances the product's performance, so that it becomes the ideal equipment of pre-grinding specimen.
