    The tendency to accumulate machining data as expertise has been increasing in the field of large die molds used for the pressing and injection molding of automotive parts. With such a background and in conjunction with the improvement of three-dimensional high-precision measurement technologies, the realization of even higher-quality and higher-precision cutting surfaces is in demand. However, large die mold processing takes a long time and has the issue of the deterioration of machining accuracy caused by thermal displacement during processing, tool wear, the deviation of the blade tip position after tool changes, etc. Therefore, it is difficult to attain high-precision cutting surfaces. We have developed a large, high-precision machine tool that incorporates the precision improvement technologies and high-precision measurement technologies of our micro milling machine, and realized high-quality and high-precision cutting surfaces to contribute to the reduction of lead time through the elimination of the need for polishing.
