    Ultra-thin Linear MPFA Scale for Industrial Machinery

    Mitsubishi Heavy Industries Machine
    Tool Co., Ltd.

    In recent years, there has been increasing demand for higher-speed and higher-precision control of linear drive mechanisms in various fields, including industrial handling systems, mobile robots, semiconductor/liquid crystal manufacturing systems, and food processing equipment. With such a background, an increasing number of devices have adopted linear motors and precision position detectors instead of conventional servo motors and ball screws. Mitsubishi Heavy Industries Machine Tool Co., Ltd. has marketed the MP (Mitsubishi Precision) scale, which is a high-speed and high-precision scale that is resistant to harsh environments, mainly for use in machine tools. This time, we have developed the optimal scale for linear motor position detection that can be used by a wider range of customers. This report presents the ultra-thin linear MPFA (Mitsubishi Precision Factory Automation) scale for industrial machinery, which is an achievement of the development.
