Operating Tips:

Universal Cylindrical Grinding Machine (UG-500, UG-630)

Features:

1. The machine is intended for cylindrical, internal and taper grinding. It is specially suitable for workshops engaged in single-piece, small and medium batch production.

2. The workpiece, cylindrical and internal grinding wheels, hydraulic and coolant pumps are driven by their separate motors.

3. The table longitudinal traverse is actuated by hydraulic means at steplessly variable speed or operated by means of handwheel.

4. The wheelhead rapid approach and withdrawal and intermittent feed are effected hydraulically. The wheel feed can also be operated by hand.
