Product Overview
The fully automatic metallographic grinding and polishing machine is used for the grinding and polishing stages of metallographic specimen preparation, integrating pre-grinding, grinding and polishing. The equipment is controlled by a touchscreen together with a microcontroller/PLC. The grinding/polishing disc is driven by a DC brushless motor, and the grinding head is driven by a stepper motor with automatic loading. Multiple grinding and polishing stages can be completed automatically according to preset speed, pressure and time, replacing manual operation and improving specimen preparation consistency and efficiency. It is suitable for metallographic specimen preparation in factories, research institutes, and university and college laboratories.
