In the course of metallographic sample preparation, the pre-grinding of the
sample is indispensable before polishing. The pre-grinding can promote the
effect of sample preparation. M-2 metallographic pre-grinding machine is
designed on basis of suggestions and requirements from various users. The
machine is equipped with handsome practical FRP casing and stainless steel
standard parts, which greatly enhances its serviceability and makes it into an
ideal pre-grinding machine of samples.
The working principle of M-2 pre-grinding machine: the clean water flows into
rotary abrasive disc via water pipe, the abrasive paper upon the water, under
centrifugal force of rotary grinding disc, throws the water under the abrasive
paper out of the abrasive disc and forms vacuum, barometric pressure presses on
the abrasive disc tightly, and the pre-grinding begins; when the abrasive disc
stops and the effect losses, the abrasive paper can be taken down at will.
