* Automatic roughing and finishing process via pre-settable counter and built-in feed cam. * Counter for number of teeth. * Counter for number of dressing cycles. * 2 built-on dressing units with three dressing diamonds for radius dressing, side dressing and wheel end dressing. * Built-on index plate for 48 teeth. * Separate coolant device with band filter. * Separate hydraulic unit. * Separate TRION oil mist exhaust. * Various small parts. The Gleason 120 is an automatic high speed machine for grinding Curvic teeth in face couplings. Concave as well as (on the opposite side) convex teeth are ground into the faces of the parts to be connected, with the advantage that the couplings both centre and drive.
