Cylindrical grinder: grinding external cylindrical parts.

Universal cylindrical grinders: grinding external and internal cylindrical parts.

1.Universal cylindrical grinders are designed for grinding cylindrical or taper surface of rotational parts. It is highly adaptable for single and small batch production.

2.The table traverse is actuated by hydraulic means at infinitely variable speed or operated by hand.

3.Auto intermittent micro-infeed and rapid approach, withdrawal of the wheelhead can be effected hydraulically, while rough-fine-feed realized by handwheel.

4.Worktable guideways are hydro-statically lubricated.

5.The grinding wheel spindle is supported by three tilting segmented shoes.

6.Workpiece, wheel, hydraulic pump, coolant pump are driven separately by individual motors.

7.Each motion part of universal cylindrical grinders is controlled by electric, hydraulic, mechanical interlocking mechanism, thus the machine can be operated easily and safety.
