    Spline grinding machine tools 3B451B Family

    Spline grinding machine tools 3B451B Family are intended for grinding of straight and serrated spline shaft as well as side grinding of involute spline shafts on radius close to involute.

    The machine operation is based on the copying process method with a profile-shaped wheel (or multiwheel) using single indexing. Optionally, on extra cost, the machine is available in a semiautomatic modification providing the machining cycle control without operator’s participation. The machining cycle provides automatic, multipass grinding with feed per revolution, indexing, wheel wear compensation and wheel dressing.

    On special order and extra cost the following special accessory could be delivered:
    — device for dressing on radius approaching to involute;
    — grinding head;;
    — grinding head for small diameter wheels;
    — set of indexing disks;
    — hydraulically powered footstock center controlled by a treadle.
