The one of the biggest feature of this machine is that it has 3 planetary counter-rotating grinding discs. When the small turntable rotates, the big gear disc rotates in the opposite direction. Its advantage is that we can feel the vibration caused by the ground during operation compared with double-headed and single-headed machines.

Our advantage

1. Upgrade the aviation standard plug, which is reliable and durable;

2. Possess a large-capacity water tank to avoid the trouble of continuously adding water;
3. The grinding disc is a three-head planetary counter-rotating system, which effectively reduces the biasing force and improves the operability of the machine;

4. The electric control box of the sheet metal shell is very firm and has good sealing performance, which can greatly extend the service life of the machine.
