• Machine tool CNC system for SIEMENS828D, five-axis three linkage;
• The longitudinal movement of the worktable and the transverse movement of the grinding wheel frame are driven by the servo motor through the reducer and the high-precision ball screw pair. The transverse movement guide rail of the grinding wheel frame is a flat and V rolling guide rail;
• The rotary motion of the headstock spindle is precisely driven by a servo motor, a worm gear and a worm pair;
• The internal thread grinding wheel spindle adopts Taiwan's electric spindle, which can realize frequency conversion speed regulation;
• Workpiece clamping is manually clamped by a four-jaw chuck;
• The machine is enclosed with a large casing and has a sliding protective door, and is equipped with an electrostatic air purifier.
