BACKING-OFF LATHES

  • Used in small batch and individual production for backing-off of worm-modular milling cutters (single thread and multiple thread, left and right), disc cutters and other tools with teeth, backed off radially, at an angle or along the axis with cutter or grinding wheel.

    Advantages:

    • ability to manufacture worm milling cutters of class A;
    • combining of lathe machining of elements of cutter teeth and finishing grinding of machines milling cutters;
    • processing of shaped elements in cam mechanism of different purposes
