    Special Equipment / Accessories:

    • Machining Process: Profile Grinding of Spur Gears by a profiled Grinding
    Wheel, one or One or two flank grinding process, the workpiece is moving up
    and down (Y-axis) and is Indexed from tooth to tooth by th B-Axis.
    The grinding head has fixed angle for straight toothed gears.
    • BWO CNC Control Model 900 (German Manufacturer) for 4+2 Axis with dialogue
    Programming of grinding programms based on the input data for an optimal
    grinding process in combination with profile and lead modifications.
    • CNC-Controlled Grinding Wheel Dressing Device with motorized Diamantroll
    mounted behind the Grinding wheel on a separate slide (Z-Axis) in
    conjunction with the axis of the grinding slide ( X-Axis)
    the software provides all modifications to involute basis profiles and
    dressing cycles. Dressing time for redressing 15 seconds, new profile
    generating takes 5 minutes dressing time.
    • DITTEL Balancing Unit , Model M 5000, with feeler and control unit
    • Hydraulically adjustable tooth gap threading device, ideal for pre-machined
