• Worktable: driven by AC servo motor through high-precision preloaded ball screw pair for longitudinal reciprocating motion. A high-precision grating ruler is installed on the front of the workbench to achieve full closed-loop control. The screw bearing adopts imported bearing;
• Head: The spindle is driven by an AC servo motor through a high-precision worm gear pair, and a high-precision rotary encoder is installed at the rear end to realize full closed-loop control. The main shaft bearing adopts imported high precision rolling bearing;
• Tailstock: double-layer structure with adjustable taper; the top of the tailstock is manually completed;
• Grinding frame: semi-cylinder structure. It is driven by AC servo motor through high-precision preloaded ball screw pair to realize transverse automatic feed, grinding wheel dressing amount compensation and cone thread grinding. The adjustment of the half-cylinder helix angle is done manually. The screw bearing adopts imported bearing;
• Grinding wheel spindle: directly driven by a rear-mounted permanent magnet synchronous motor and adopting AC frequency conversion technology to realize stepless speed regulation; the bearing of the spindle adopts high-precision hydrostatic bearings, and the hydrostatic oil tank is equipped with an oil cooler to ensure the oil temperature of the oil tank Constant, reliable operation of the spindle;
• CNC grinding wheel dresser: the use of cross table structure, by the horizontal movement and vertical movement of the two CNC axis and the diamond wheel drive mechanism. The two CNC axes are interpolated together, and the grinding wheels of various types of lines are trimmed by a single disc diamond roller driven by an AC servo motor. The guide rail adopts imported high-precision linear guide rail; the diamond roller can provide imported or domestic rollers according to user requirements;
• Configuration of fully enclosed large enclosure and imported oil mist processor.
