    High Speed CNC Internal Grinding Machine HMN-110 With CBN Grinding Wheel

    HMN-110 CNC Internal Grinding Machine CBN grinding wheel high speed grinding

    I Working principle:
    The CNC centerless internal grinder adopts double fulcrum and electromagnetic chuck for clamping and positioning. The processing method adopts numerical control oscillating grinding. The worktable is composed of two axes, X and Z, both of which are driven by a servo motor through a ball screw. The grinding wheel axis is located above the worktable, and the workpiece axis and the correction axis are fixed.
