(*) Valid also for prepared bars or normal bars machined with front remnant ejection.
(**) Recommended guide channel according to the maximum lathe bar passage.
Example: ø85 maximum bar passage — GUIDE CHANNELS 86-61-33.
Example: ø80 maximum bar passage — GUIDE CHANNELS 81-61-33.
Example: ø75 maximum bar passage — GUIDE CHANNELS 76-61-33.
WARNING — CAUTION:
barstock diameters for any guide channel are only given as an example. A
barstock diameter 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.
