High-precision semi-automatic universal cylindrical grinder

Machine features:

★This series of machine tools are suitable for high-precision grinding of the outer and inner surfaces and end faces of cylinders and cones of small and medium-sized precision shafts and disc parts.

★The machine table, headstock, grinding wheel frame and other components can all be rotated at a certain angle.

★Friction-reducing coating technology is adopted for both the traverse and the bed guide, which can effectively remove the phenomenon of low-speed crawling, and the coating has a good shock-absorbing effect, which greatly improves the grinding precision.

★The main shaft of the headstock and grinding wheel frame adopts the overall large taper forming oil wedge dynamic pressure bearing structure, which has the characteristics of high rotation precision, high rigidity and low temperature rise.

★The tailstock adopts the dense ball sleeve structure, which has the function of hydraulic expansion and contraction, and realizes hydraulic advance and retreat and spring clamping.

★The movement of the worktable and the advance and retreat of the grinding wheel frame can be performed hydraulically or manually, and it has the function of semi-automatic fixed-range grinding of workpieces in various ranges.
