Operation demo video:
In the process of metallographic sample preparation, the grinding and polishing of the sample is an indispensable process. After the sample is ground and polished, a bright mirror-like surface can be obtained. The metallographic sample grinding and polishing machine adopts a frequency converter to adjust the speed, which can make the speed of the grinding and polishing disc infinitely adjustable between 50-1000r/min. The grinding and polishing of the sample can be completed by replacing the metallographic sandpaper and polishing fabric. It is especially suitable for metallographic laboratories in factories, colleges and research institutes, and is an excellent equipment for grinding polishing metallographic samples.
Features:
1. One machine can do the rough grinding, fine grinding, rough polishing and fine polishing of metallographic specimens.
2. Double working plates φ250mm, double times improved working efficiency.
3. Pneumatic version automatic grinding head, one time can process 6 pieces of samples (4 pieces of GP-3A).
4. Integral moulding of high-strength FRP material shell, sturdy and durable, never rusty.
5. The faucet adopts copper material, which has good corrosion resistance
6. Stepless speed design, low noise, stable working performance. Can meet meet a variety of needs.
7. With water cooling system to prevent damage to the metallographic structure due to overheating of the sample. And can get more better metallographic surface easily.
