    Heidenhain 426 Cycle 203 drilling Paramater speed redudtion

    Hi ,
    does anyone know how to reduce the rapid speed for cycle 203 Universal drilling on a Bridgeport VMC 1000 Heidenhain 426 as its far too quick for what I`m using it for one one offs and not production work.
    Thanks.

    Hi,

    I have three DMU 50 evolutions- two of which have potentiometers on the keyboard to over ride the rapid feed rate. In case if yours does not have this, I would suggest programming a high drilling feed rate and reduce the general feed rate override (which controls both feed and rapid movements - we follow this process on one of the evolutions which doesn't have a separate rapid override)

    I unfortunately do not know how to control the feed rate in the cycle as requested.

    Best regards

    Jaideep
