ACCESSORIES - FOREWORD
To improve the bar feeder performance and increase its versatility, the following optional
devices are available:
2.7.1 Bush holder device - Description
It is attached to the front part of the bar feeder.
Its function is to reduce bar vibrations to a
minimum, by keeping the bar centered during
rotation by means of two half-bushes A, which are
coupled to form a round channel with a diameter
just slightly larger than that of the bar being
machined.
In many cases, this device may be used (by only
changing the diameter of the half-bushings) to
greatly extend the range of diameters which can
be machined without having to replace the guide
channel.
Operation
• When the bar is dropped into the guide channel, the two half-bushes are open.
• The closing phase is controlled by a pneumatic cylinder when the bar feeder has completed
the bar loading cycle. The oil flow for the machined bar lubrication and support starts
together with the closing phase.
• When the bar pusher approaches the device, the half-bushes open up to allow its passage
and the oil flow stops.
