    The MVR‐Dχ series of portal bridge type, 5‐face milling machines are valued by customers as high‐speed and high‐precision efficient machine tools, in addition to having a high‐rigidity structure that enables heavy cutting. Since their release in 2008, Mitsubishi Heavy Industries (MHI) has delivered more than 50 machines in the MVR‐Dχ series to customers in all industrial machinery fields including construction machinery, motors and machine tools. In particular, many have been introduced to customers handling railway equipment. This document presents examples of where standard machines in the MVR‐Dχ series capable of heavy cutting were modified to meet individual customer needs, and resulted in further improvement of production efficiency.
