1、 Overview
This type of metallographic sample grinding and polishing machine is a double disk desktop computer, which has the functions of freely selecting the rotation direction of the grinding and polishing disk and quickly replacing the grinding and polishing disk. This machine adopts an advanced microprocessor control system, which allows two people to operate the grinding and polishing processes at the same time, thus making this machine more widely applicable. The machine is characterized by stable rotation, safety and reliability, compact structure and low noise; With a water cooling device, the sample can be cooled during grinding to prevent damage to the metallographic structure due to overheating of the sample. It is an ideal sample preparation equipment for enterprises, scientific research institutions and laboratories in colleges and universities.
