Equipment Highlights

Equipment Highlights

Double columns and stepped beams form a high-rigidity gantry frame structure. The bed adopts a flat and a V-shaped hydrostatic guide rail. The worktable is controlled by two single-acting oil cylinders to move longitudinally along the bed guide rail. An independent hydraulic station is adopted. Stepless speed regulation, low friction and low noise, and smooth movement. A set of horizontal grinding heads and vertical universal grinding heads are equipped. The grinding heads move horizontally and vertically by servo motors to drive screw screws, and vertically by grating ruler positioning, to achieve horizontal pitch grinding, intermittent feed, micro feed, stepless speed regulation and other functions.
