    Large die molds are necessary for the production of large parts used for automobiles, electric appliances, etc., and are increasingly produced overseas. With an increased need for stable, high-quality die mold manufacturing, however, there is also a move toward return production to Japan. In addition, for today's machine tools for molds, higher precision in terms of machined surface quality, such as that at the level that needs no polishing and reduces the stepping caused by thermal displacement, etc., is required. Against this backdrop, Mitsubishi Heavy Industries, Ltd. released the MVR-Eχ large double column machining center, which is equipped with the high-precision technology adopted for the recently released LH250 high-precision machining center (Table 1). This paper presents the technological features of the MVR-Eχ, which realizes high-precision machining, and also details a cutting example.
