    In recent years, the shapes of parts and molds have become more complex, finer and more precise with the sophistication of functionality and design of industrial products including automotive components. The number of parts requiring a precise fine shape on their surface with size and depth, such as molds for automotive headlights, has been increasing as well. For the machining of such parts, both rough machining ability for forming a shape from a material and high-speed and high-precision machining ability for forming a fine shape are required. In addition, mold materials have become harder and more difficult to cut in order to realize lighter products with higher strength, so the need for high-speed and high-precision spindles has been increasing. Mitsubishi Heavy Industries Machine Tool Co., Ltd. developed a high-speed and high-precision spindle for the μV1small micro milling machine and have been working on high-speed and high-precision machining using small-diameter tools for the machining of high-hardness and difficult-to-cut materials. This report introduces features and machining examples of the μV5 micro milling machine, which can handle a wider range of workpiece sizes and has a higher rough machining ability in comparison with the μV1.
