WARNING – CAUTION:
diameters for barstocks in any guide channel are only given as an indication. A
diameter of a bar to be machined approximately 10 mm smaller than the guide
channel diameter may cause vibration and failure to the bar feeder. Therefore, it
may be necessary to slow down the bar rotation speed or to change the guide
channel diameter in order to obtain the best performance.
WARNING – CAUTION:
the collet external diameter should be at least 0.5 mm smaller than the bar
pusher external diameter.
INFORMATION:
the bar feeder is usually supplied with a bar pusher whose diameter is equal to
the maximum bar passage of the lathe. Sometimes, in order to ensure the best
working conditions, it may be necessary to use a bar pusher with a smaller
diameter.
