| Trans-Bar
55+ is the universal flexible version of the CNC bar transfer
machine most prevalent all over the world. Our machine is
capable of finishing parts that cannot be finish machined
on single or multi-spindle automatics due to their re-clamping
and transverse feature requirements. It is able to do so
in the shortest possible cycle time. This highly productive
machine requires only 30 - 90 minutes for a complete tool
changeover making it ideally suited for small batch manufacturing.
|
|
Machining bar stock
parts on two ends and any one of five sides simultaneously, as well
as machining entire external and internal surfaces, is possible on
the Trans-Bar 55+ as a result of the following machining spindle configurations:
- 10 universal horizontal spindles
(5 on the right and 5 on the left) plus 11 optional spindles for
special applications;
- 5 universal radial spindles (optional for
transverse machining and for "rotating part" turning
operations).
|
|
Buffoli universal spindles
(7.5 kW) can be equipped with quick-change machining
heads including:
- Buffoli CNC static turning
contouring heads;
- Compact multi-process modules equipped with up to
three tools which include 3 axis positioning and a
0.5 second tool change;
- Heads for rolling, marking, knurling, broaching
and milling.
|
For a total of 29 tools
(9 on the left, 9 on the right, 11 radial) plus
further 11 horizontal for special applications.

(for grooving, recessing, contouring, facing and threading with
low-cost standard inserts)

The part transfer for the first
clamping or subsequent re-clamping can occur in different
stations by integrated pushers or manipulators.
The machining area is kept perfectly clean with abundant high-pressure
coolant system (up to 1000 liters per minute) assuring long
tool life, efficient chip evacuation and precise quality.

Buffoli multi-process modules equipped with three tools for drilling
and tapping and/or off-center or transverse milling including polygon
contouring.
|
| All
electronic, pneumatic and hydraulic components are designed
to be outside the machining area to assure reliability and
ease of maintenance.

Machine
accuracy and machining quality (repeatability, capability)
is guaranteed by designs and construction principles that avoid thermal
influences on the mechanical components.
Alignment and parallelism among machined features
is assured by multi-direction simultaneous machining.
Buffoli specific solutions result in particularity precise
concentricity tolerances.
Buffoli machines have an international reputation for reliability
and rigidity. Buffoli customers continue to enjoy high efficiencies
(95%+) while maintaining the highest levels of quality, for sustained
periods of operation, including round-the-clock, continuous, operations,
over the course of many years.
The Buffoli CNC with digital electronics is highly reliable and backed
by an unprecedented five-year warranty.
