Mitsubishi Heavy Industries Machine Tool Develops "MVR-Fx," High-Precision Double-Column Machining Center for Die Molds Application

The MVR-Fx features a high-rigidity symmetrical structure and columns equipped with thermostabilizers that prevent minimize deformations caused by fluctuations in the ambient temperature. The main spindle adopts an internal cooling mechanism that performs direct cooling by passing the oil coolant inside the spindle . This feature suppresses temperature changes and unstable rotation during high-speed operation (20,000 revolutions per minute). In its feed drive mechanism, the MVR-Fx features a newly developed "Zero Gap Drive System" in which the servo motor is directly connected to both ends of the ball screws, achieving enhanced kinetic performance. Together, these various mechanisms achieve die mold machining of superlative precision and definition without having to adjust the servo motor for thermal displacement or coordinate compensation.

To further boost efficiency in die mold machining process, the MVR-Fx can be optionally equipped with "optical type automatic tool measurement system," a system with a performance track record proven in high-precision machining centers μV1. The MVR-Fx can also accommodate ATOS, the latest optical 3D measurement system for automatic measurement of machined workpieces. The exhibition at JIMTOF will highlight the MVR-Fx's machining precision capabilities, utilizing ATOS.

The MVR-Fx is a new type of machine tool based on a concept of "Factory Friendliness." It has a full enclosure to secure the safety of the worker, its layout has been designed with a focus on the proximity of the operator to the workpiece, it uses LED lighting to save energy, and the overall design reduces oil and air consumption.

For large die molds of the kind used in stamping car bodies and injection molding there is currently strong demand for machining with ever-higher precision and . This is achieved by improving the strength of the die mold materials, digitizing technologies and information, and enhancing design quality. With its market launch of the MVR-Fx, a machine tool to resolve those issues by targeting "Zero gaps, Zero shape imperfections, and Zero hand finishing," Mitsubishi Heavy Industries Machine Tool looks to realize higher efficiency by reducing the number of test pieces, thereby creating value for the customer.
