◆The layout of the machine is the movable table t-type layout, and the leftright movement of the table (z-axis) and the transverse movement of the wheelhead(X- axis) are driven by the servo motor and ball screw.
◆Lubrication by intermittent lubrication pump for centralized lubrication ,The workhead is a dead center structure, and the tailstock workpiece is manually jacked and released. The adjustment of jacking force can be realized by adjusting the com-pression quantity of the spring. The wheelhead is a dynamic bearing structure of tile, which has good grinding rigidity and high precision.
◆Workpiece grinding can realize CNC programmed automatic grinding, which can meet the requirements of automatic grinding of most small and medium-sized parts.
