10 - GUIDE CHANNELS - BAR PUSHER - REVOLVING TIPS BOSS 332/545/552 HD
10 - Pag. 4 / 16
WARNING – CAUTION:
the application field of the collets for machining specific barstock diameters in
the guide channels are indicated in the table. If the bar diameter is smaller by
about 10 mm with respect to the guide channel diameter, vibrations and failures
may arise in the bar feeder. Therefore, in order to optimise the operation, the
bar rotation speed should be reduced or the guide channel diameter should be
changed.
INFORMATION:
upon specific request, non standard collets with reduced thickness (which are
not mentioned in this table) may be supplied as well. Their durability is however
below the durability of standard collets.
