    ZE16C/26C Gear Grinder - Supporting Gear Manufacturing with High Precision and Efficiency

    Mitsubishi Heavy Industries Machine
    Tool Co., Ltd.

    In recent years, the need for high-precision and low-cost gear manufacturing has been growing against the backdrop of increasing demand for the electrification of automobiles, low fuel consumption and low noise, as well as the miniaturization of reduction gears for robots. In the manufacture of high-precision gears, gear grinding is commonly performed to improve the deterioration of shape accuracy after heat treatment. Accordingly, there is an increasing demand for gear grinders that make the stable mass production of high-precision gears possible. Mitsubishi Heavy Industries Machine Tool Co., Ltd. has developed the ZE16C that adopt - stracture and the ZE26C, a series of gear grinders on the basis of gear processing technology cultivated until now, to meet the needs for high-precision, highly-efficient gear manufacturing. This paper presents these products with our efforts for high-precision manufacturing and our unique water-soluble coolant that meets the needs for environmental load reduction and energy conservation.
