Features: The hydraulic circuit is uniquely designed to ensure that work pressure is adjustable, and for smooth output pressure.
Low-frequency oil pump motor features very low noise, even higher efficiency, and extended service life.
The driving and hydraulic motors feature high torque, and that ensure both circle rolling and semicircle formation precisely processed, and that outer diameter is freely adjusted.Incorporates a precise electrical control system.
Each section of the unit can be either electric-powered or manually operated.
