Nidec Machine Tool Corporation (led by Kenichi Wakabayashi, president, and headquartered in the city of Ritto, Shiga Prefecture) announced recently that it has launched MVR-Ax, the series of the company’s new models of double-column machining centers, on the same day. These new products were developed as easy-to-use machines to meet the diverse needs of manufacturing sites that machine large-size components.
Together with their predecessors, i.e., high-end model MVR-Hx and standard model MVR-Cx (intended mainly for mid-size workpieces), both launched last October, the MVR-Ax series can use a great number of options – ranging from a table size that can accommodate large-size workpieces to an abundance of attachments to the main axis to automated functions such as a palette changer – for a variety of users’ applications. In addition, the high-performance grinding technology and the digital technology to improve operability and maintenance capability enhance the MVR-Ax machining centers’ overall productivity. We will offer these new machines to our products’ users, domestic and overseas, for the purpose of developing new markets.
The machining centers in the MVR-Ax series are equipped with a main axis that rotates at a standard speed of 6,000 times per minute to machine large-size workpieces such as industrial, construction, semiconductor manufacturing, and power-generating equipment, and with a gear drive main axis (opt.) (4,000rpm, with a maximum torque of 3,430N▪m) for deeper cutting operations.
Combined with resilient structures of their main unit, which remain completely undamaged from this high torque, the products have sturdy ram main axes that enhance the cutting capability during ram protrusion, while enhancing the performance of the machining of tall components’ lateral sides. Additionally, a large number of attachments enable the machining centers of the MVR-Ax series to machine objects of various shapes, including narrow sections, multifaceted surfaces, slant planes, and adjustable surfaces. Furthermore, the individual axes’ fast-forwarding speeds are top-class in the industry, with 30m/min. for the x-axis, 32m/min. for the y-axis, 20m/min. for the z-axis, and 5m/min. for the w-axis. The shortened non-cutting time makes the MVR-Ax series highly productive.
To seek usability, we reflected the voices of our products’ users in the MVR-Ax series by installing, as standards, the “NidecNavi,” an operational assistance function to help the operator make NC programs and perform centering work efficiently, and the “simple collision prevention function” to prevent tool-work collision. In addition, with the use of “DIASCOPE,” our company’s unique IoT platform, we provide swift, secure, and hassle-free support for the MVR-Ax series. The products’ other features include, among technologies to enhance their environmental performance, an idling stop function for the oil cooler and the hydraulic unit to reduce electricity consumption and serve other energy-conserving purposes.
Having been delivered to and widely used in mold, industrial machinery, construction equipment, semiconductor production equipment and many other fields of business, the MVR series seeks to achieve an optimum mechanical performance, as well as an excellent usability and environmental performance based on its user-friendly, secure, and supportive designs.
Nidec Machine Tool stays committed to offering machine tools that are needed in all industries to contribute to improving their customers’ manufacturing capabilities.
