2.7.3 Diaphragm bushing device OPTIONAL (for Elite 220 only) - Description
This device, attached to the front of the bar feeder,
reduces bar vibration to a minimum by keeping
the bar centered during rotation. It uses three
diaphragms, which, when closed, form a semi-
circular channel with a diameter slightly larger
than that of the bar being machined.
The channel created by the diaphragms must be
adjusted every time a bar with a different
diameter is loaded.
OPERATION:
- When the bar is dropped into the guide channel,
the diaphragm bushing device remains open.
- The closing phase is controlled by a pneumatic
cylinder and occurs 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 diaphragm baffle plates open to allow it to
transit and the oil flow is simultaneously discontinued.
2.7.3.1 Additional bush device - Optional - Description
The additional bush (B) is installed in the rear part
of the sliding headstock lathe and allows keeping the
bar guided for a space additional to the opening of
the first bush (A) .
The additional bush (B) performs the opening and
closing movement in automatic mode and it is
activated by the value set in the "Bar End
Adjustment 1" subparameter.
For more detailed information please refer to the
instruction manual.
INFORMATION:
The additional bush accessory on the
lathe is installed if applicable from the
lathe-bar feeder mechanical interface or
upon customer's request.
