Highlights
Simple and user-friendly operability and workability
Numerical-controlled swivel of wheelhead enables helix angle change by easy numerical entry. It provides high-accuracy thread grinding for various workpieces such as spindle, tool, thread gauge, ball screw, etc.
Full-closed control on each axis achieving high-accuracy thread grinding
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.
