Machines for rotor cutting:

This equipment serves for the machining of commutator electric motors. The machining procedure consists in the cutting or rotor packs and during this operation all the residues of impregnation resin are removed. The proces includes also rough commutator cutting and after the change of rotation direction also the final cutting. In the end the commutator is cleaned with several rotating brushes.


This machine is controled by means of Mitsubishi control system, all the commuation with operators is carried out through the control panel equipped with a multiple-line display. This control system enqbles to set the cutting parameters (rotor speed and carriage feed rate) directly on the control panel. Cutting conditions can be modified continuously even during the working cycle.


The machine can be installed as separate working site with an operator. The loading and withdrawal of the machined rotors is realized with gravitational containers not to cut off the working process. The equipment can be embodied into the assembly line as well.

This equipment can modified in compliance with the special requirements of our customers. We can change both the design and the equipment with the control and operating components.
