Highlights

High-accuracy thread grinding machine with excellent operability having distance between centers 800mm

  • Numerical-controlled swivel of wheelhead enables helix angle change by easy numerical input.
  • It provides high-accuracy thread grinding for various workpieces such as spindle, worm shaft, thread gauge, ball screw, etc.

Closed loop positional feedback for each axis providing the highest accuracy thread grinding results

  • Rotary encoder with 0.0001°control on work spindle, and optical scale feedback control on X & Z-axis are equipped as standard.
  • By equipping built-in type grinding spindle as standard, machine vibration is minimized to achieve high-accuracy thread grinding even with small-diameter thread.

Improvement in stability of pitch diameter of thread

  • Locating the dresser on the back of the work spindle enables minimizing error in X-axis travel and improves diameter accuracy.

Easier replacement of the grinding wheel and the dresser

  • Easy access from a side door, and a top door available for crane operation.
