Other Details

The DTM – 2X Commutator Turning Machine has been designed for precise turning operations on commutators. The machine comprises of a solid heavy machine base housing atwo axis servo slide with a tool holder. The armature is supported free across two Diamond V Block supports on the bearing area to facilitate stress free centre less turning. The armature is rotated by a swivel arm belt drive with stepless speed control.
 
Both the longitudinal traverse and the cross slide are controlled by a precision electrical AC servo motor coupled to a ball screw to facilitate programmability of both diameter and the length of travel.
