SMK304 CNC Internal Thread Grinder

-Grinding for Internal Thread and circular INQUIRY

 The grinding machine is professional to processing in ball nut of Internal thread, cylindrical and ending surface for once clamping.

T type mineral casting frame get better in vibrating and heat distortion.

The diamond dressing wheel install on Z axis, and let grinding wheel dressing amount can be compensated automatically

●A axis motor let internal grinding wheel to swing angle +-25° by automatic program.
