Ball screw grinding machine TGN 30/80

CNCstationary

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.
