Laboratory Grinder Polisher Metallographic Specimen Grinding & Polishing Machine

* Central force loading mode, fix six samples at one time, complete all grinding and polishing processes, and ensure the complete plane of each sample.
* Independently control the grinding and polishing disc and sample disc: control all grinding and polishing parameters such as rotating speed, grinding and polishing time, rotation direction, water valve closing, etc.
* Touch screen interface: it is convenient to set grinding and polishing parameters, intuitive status display and simple operation.
* The loading force can be adjusted in operation, flexible and convenient.
* The on-off of water is controlled by solenoid valve.
* By easily replacing the magnetic anti sticking disc, all processes such as rough and fine grinding, rough and fine polishing of various samples can be completed. One disc is equivalent to several discs.
* High precision, stable operation and low noise.
* Thickness control of sample grinding layer: accurately control the grinding amount of samples and grind them to the specified position (Optional).
* External dispenser control the dropping speed and dropping material (Optional)
