The DC motor armature finish turning machine is use for armature commutator turning and it can turn and brush the rotor simultaneously.
(1) Introduction and features
Manual load/unload of armature into the turning and brushing stations.
Armature commutator turning and brushing the rotor at the same time
Servo motor drive controls armature rotation.
Robust, vibration-free base and tooling mounting surfaces.
Complete control of belt speed for correct cutting surface speed.
Supporting Clockwise or counterclockwise rotation of armature during cutting.
High precision
Easy access for maintenance.
Low cost
Easy to operate
