Worm Grinder Technical Descriptions

TC-7720 CNC thread grinding machine is equipped with FAGOR CNC system to achieve four-axis, Triple linkage control.

The rotary motion of the workpiece, the lateral motion of the table, the rotary motion of the screw angle and linear motion, and the linear motion of the diamond roller are all controlled by YASKAWA servo motors. The rotary motion of workpiece, transverse motion of table, rotary motion and linear motion of helix lifting angle, and linear motion of diamond roller are all driven by YASKAWA servo motors from Japan.

The diamond roller is controlled by the electric spindle. The rotary motion of the grinding wheel spindle is driven by internal AC permanent magnet synchronous motor. The rotary motion of the grinding wheel spindle is driven by an internal AC permanent magnet synchronous motor.

The rotary motion of the workpiece, the transverse motion of the table, the rotary motion of the helix angle and the linear motion of the diamond roller are all driven by YASKAWA servo motors. The rotary motion of the workpiece, the lateral motion of the table, the rotary motion and the linear motion of the helical lift angle, and the linear motion of the diamond wheel are all equipped with Spanish Fagor scales to achieve full closed-loop control.

The X-axis and Z-axis linkage interpolation realises the dressing of various grinding wheels’ truncated shapes, and the dressing amount of grinding wheels can be adjusted by X-axis and Z-axis linkage interpolation. The dressing amount of the grinding wheel can be automatically compensated by the longitudinal movement of X-axis.
