The main components of the grinding bed . Grinding bed is the foundation support , on top of it with wheel frame , table, headstock , tailstock and horizontal saddle and other components. These components work to maintain the exact relative positions. Bed inside as hydraulic oil sump . Head frame for mounting and clamp the workpiece and the workpiece driven rotating head frame in the horizontal plane can turn counterclockwise 90 °. For supporting the inner circle of abrasive grinding wheel spindle bore . Grinding the inner circle by a single motor drive shaft . Wheel rack for supporting and driving high-speed rotating grinding wheel spindle . Wheel rack mounted on the saddle , when required short conical surface grinding , the wheel frame can be adjusted in the horizontal plane to a certain angular position ± 30 °. Tailstock and headstock with the support of the top piece . Saddle and cross feed mechanism rotating infeed handwheel . Can make the infeed mechanism driven wheel on the saddle and frame for the infeed movement. Bench composed by the upper and lower levels . The table rotatable about a horizontal plane under the rotary table at an angle (± 10 °)? For grinding is not a long taper conical surface , on top of the table with the headstock and tailstock . They can be together with the table along the rail bed longitudinally reciprocating motion. Machine uses: general accuracy level universal internal grinder , machine accuracy IT6, IT7 level . Machining surface roughness value Ra of 1.25 and can be controlled in the range of 0.08μm . Universal internal grinder can be used within the inner cylindrical surface of the inner conical surface finishing , although productivity is low, but because of internal grinder universal versatility is better, is widely used for single and small batch production workshop, tool shop and machine shop .
