The Universal Cylindrical Grinding Machine is designed for grinding cylindrical or conical external surface with accuracy of IT5 and IT6. It is most suitable for tooling or repair workshop in small batch production. The longitudinal travel of worktable is controlled steplessly by hydraulic system or by hand wheel. The infeed of wheel head is carried out by hydraulic automatic periodic feed and also by hand wheel. The rapid approach and withdrawal of wheel head retracting of tailstock center lubrication of slide way and lead-screw are all hydraulically controlled.
