SQ820

Positioning: Independently controlled dual drives with rigid gear transmission.
Advantages:
▪ High-torque dual-drive system: Main disc and satellite discs have independent speed and direction control, so both drives work together for strong overall productivity.
▪ Flexible control: Fully adjustable parameters and omnidirectional travel — cutting force is fully controllable for all kinds of complex job conditions.
▪ Rigid gear drive: High-strength alloy gear sets provide efficient, slip-free transmission with stable performance over long hours.
Positioning: For commercial floors and precision shops where both finish quality and flatness matter. Handles surface prep and polishing — an all-around machine for multiple floor materials.
