The dual motor driving systems can drive the floor grinder in four directions, turn left and right smoothly. Two motors which propel the machine forward with no effort from the operator. Operator can focus on the floor status. Advanced JS Self-propelled wire control technology and newest gear box systems make the floor grinding polishing an easy job, guaranteeing the floor is super flat and smooth.
Advantage of JS round planetary gear box:
Double layer gear, no belt
Aluminum integral casting gear box
Quick-change magnetic tooling systems
Variable-speed soft start
Both grinding and polishing, both wet and dry
Be good at high gloss and smooth surface polishing
The machine's revolution leads four grinding heads running in different directions, offsetting the traction effectively between the grinding heads to make the operation smooth and easy. The work area between each head enhances the pads to effectively run the operation.
Planetary grinder can be used for all grinding and polishing applications (wet or dry), adhesives and coating removal, surface repair and flattening of concrete, terrazzo, etc.
