680-4A self-driving terrazzo, marble, cement and concrete floor grinding wheel polishing machine is a self-driving grinder and one of the most efficient floor grinding equipment produced by Xingyi Company. Adopting a four-head planetary counter-rotating gear structure, the planetary gears rotate in different directions, which reduces the deflection force of the machine, has strong grinding efficiency and stable performance, makes grinding more stable and uniform, and improves grinding efficiency. And it saves time and effort. Compared with the three-head grinder, the four-head grinder has more force on the uneven surface and the work is more stable. This grinding machine has an automatic drive system, 15HP world-class WEG motor, 20HP Delta frequency converter, plus a weight of 425KG, with high grinding pressure and stable performance. If you are looking for a user-friendly and efficient floor repair and removal machine suitable for industrial applications, then there is no doubt that 680-4A is the right choice.
