CAUTION:
the field of application of collets for machining specific bar diameters in the
different guide channels are indicated in the table. When this diameter is lower
than the diameter of the guidechannel, there can be vibrations or working
problems in the barloader. It is useful to consider the possibility to reduce the
speed rotation of the bar or to change the diameter of the guide channel to
optimize the application. Therefore, in order to optimise operation, the bar
rotation speed should be reduced or the guide channel diameter should be
changed.
