FeaturesFeed and dressing movements are controlled by means of two independent driving system. Size metric grinding is adopted. Feed movement can be carried out both manually and hydraulically.Because the machine is equipped with jumping mechanism, it is unnecessary to reset the tool after returning grinding wheel for measurement or dressing.The machine is equipped with a hydraulic switch valve to ensure safety during loading and unloading workpieces.A grinding spindle with 18000r/min is optional for grinding bore diameter ranging from 20 to 50 mm
