    In the process of metallographic sample preparation, sample polishing is an indispensable process. Sample polishing is generally divided into two processes: rough grinding and fine grinding. The purpose of rough grinding is to obtain a flat surface, and the purpose of fine grinding is to eliminate these wear marks, so as to obtain a flat and smooth grinding surface to prepare for the next step of polishing. M-1 metallographic sample pre-grinding machine can be used for pre-grinding of metallographic samples. The shell is made of high-end ABS plastic in one piece, with a novel appearance, and has the characteristics of stable rotation, low noise, convenient operation, high work efficiency, etc. It also has its own cooling device, which can cool the sample during grinding to prevent the metallographic structure from being destroyed due to overheating of the sample. It is especially suitable for metallographic laboratories in factories, colleges and universities, and scientific research institutions.
