Application and characteristics of machine tool

The CNC worm grinder is an eight axis CNC worm grinder. The machine tool is equipped with Siemens 840dsi numerical control system to realize the eight axis three linkage control. The machine tool realizes the thread movement through the two axis linkage of the rotary movement of the workpiece and the longitudinal movement of the worktable. The dressing of grinding wheel is controlled by special worm dressing software. The dressing tool is diamond disc wheel. The tooth profile of grinding wheel can be trimmed by the interpolation movement of two CNC axes of the dresser. The dressing amount of grinding wheel can be automatically compensated by the transverse movement of the grinding wheel frame.

The rotary motion of the workpiece, the longitudinal motion of the worktable, the transverse motion of the grinding wheel rack, the rotary motion of the rotating cylinder of the grinding wheel rack, the two coordinate motion of the grinding wheel dresser, and the rotary motion of the dresser and the diamond disc wheel are all driven by Siemens AC servo motor. The rotation of the grinding wheel spindle is driven by Siemens built-in AC permanent magnet synchronous motor, and the grating ruler is configured for the longitudinal motion of the worktable and the transverse motion of the grinding wheel frame to realize the full closed-loop control. The head frame rotary motion is equipped with angle encoder to realize full closed-loop control.
