Reduced energy consumption and demand for consumable parts, as well as an integrated generator are some of the developments featured on Mitsubishi Electric’s new MV series wire-cut EDMs. The company claims it has succeeded in reducing energy consumption by up to 42%, and also the demand for wear and consumable parts has been minimised through the implementation of specific measures. To move a number of axes, the MV-series machines use tubular shaft motors which are designed to prevent ‘cogging’ and ensure smooth and highly controllable movements, says the company. An optical network is now responsible for data exchange within the drive system. Communication between the individual machine components occurs via fi bre optic cables. Automatic auto wire threading has also been optimised. An integrated generator forms the basis for all wire-cut processes.
