Tokyo, May 22, 2014 - Mitsubishi Heavy Industries, Ltd. (MHI) has completed development of and introduced the "MVR-Ex," a new model in the MVR Series of double-column 5-face milling machines that is one of MHI's leading large-size machine tool product lines. The new model incorporates the same main spindle internal cooling technology used ultra-high-precision machine tools, and is the first double-column machine tool in Japan to feature thermostabilized columns as standard equipment. Thermostabilization ensures superior machining precision by suppressing column deformation caused by fluctuations in the ambient temperature.
A 15-inch control panel screen, roughly twice the size of earlier offerings, has been adopted for enhanced display of necessary information. Other operator-friendly features include improved maintenance screens and simple centering during workpiece setup, as well as a remote monitoring maintenance service function to enable the machine's operating status to be remotely monitored by MHI's service center for swift servicing response in the event of malfunction detection. The latest numerical control (NC) programs are also supported, along with an array of attachments that includes a right-angle head for machining lateral faces without a setup change.
For environmental compatibility the MVR-Ex is equipped with features such as a power regenerative function for the main spindle and servo motor, and LED lighting. These and other energy-saving features result in a reduction in CO2 emissions of approximately five tons per year in comparison to previous models.
The MVR Series, originally launched in 2003, has been widely acclaimed for its outstanding machining precision and productivity. To date, close to 1,000 units have been delivered, primarily for use on production floors in plants making molds, industrial machinery, construction machinery, semiconductor manufacturing equipment, and other industrial products. Now, the MVR-Ex takes machining performance to an even higher plane.
With the introduction of the new MVR-Ex, MHI has not only responded to the replacement needs of existing users but also set the stage for proactively winning new users who seek more advanced equipment.
Note: The ram is a square, hollow column that performs reciprocating motion and supports the main spindle.
