Description
Features of CG and UCG Series Cylindrical Surface Grinders
Grinding Capabilities
- CG Series:
- Suitable for grinding the outer surface of cylinders and tapers.
- UCG Series:
- Suitable for grinding both outer and inner surfaces of cylinders and tapers.
Worktable Movement
- Longitudinal Movement:
- Driven by hydraulic system or handwheel.
- Capable of certain degrees of movement for grinding tapers.
Wheelhead Cross Feed
- Hydraulic Drive:
- Realizes automatic periodical feed and rapid feed.
- Offers rough and fine feed through handwheel control.
Guide Way and Spindle
- Hydrostatic Lubrication:
- Used in worktable and wheelhead guide ways of the CG50 and UCG50 series for smooth low-speed movement.
- High Rigidity Bearings:
- Spindle supported by hydrostatic and hydrodynamic bearings for high rotary accuracy and rigidity.
Wheelhead Motor and Speed Control
- CG50 Series:
- Adopts a double-speed motor with speed change via belt position adjustment.
- UCG50 Series:
- Features an inverter motor for stepless speed changing.
- Spindle adopts a sliding bearing structure.
Workhead and Grinding Options
- Workhead Rotation:
- The workhead of the universal type (UCG50) can rotate within 90° counterclockwise for inner or outer taper grinding.
- Internal Grinding Apparatus:
- Supported by precise roll bearings.
- Driven by separate motors for various spindles and pumps.
Design and Operation
- Interlock Structure:
- Electric, hydraulic, and mechanical interlock structure for moving parts.
- Control Panel:
- All control levers are centralized on the panel for easy operation.
- Wheel Dresser:
- Can be assembled on the worktable surface or on the tailstock.
