This grinding and polishing machine is a single-disk, single-motor, single-control type, suitable for pre-grinding, grinding and polishing operations on metallographic samples. This machine has stepless speed regulation and four-speed fixed speed, which can directly obtain a speed between 50-1000 rpm, and can also quickly set the speed to 250/500/750/1000 rpm, making this machine more widely applicable. It is an indispensable equipment for users to make metallographic samples. This machine is equipped with a cooling device, which can cool the sample during pre-grinding to prevent the metallographic structure from being destroyed due to overheating of the sample. The machine is easy to use, safe and reliable, and is an ideal sample preparation equipment for factories, scientific research institutions and laboratories of colleges and universities.
