began the production of turning machines in 1981. These machines
can be dedicated or flexible. Dedicated machines are mainly designed
for double production and are capable of producing as much as 3 or
4 multi-spindles (up to 10,000 brass parts/hour, 500-1,800 steel parts/hour).
Flexible CNC versions offer extremely short cycle times, along with
tool change over times of 40-60 minutes, a testament of their versatility
Buffoli turning machines are able to complete those more complex parts
that usually would require secondary machining. They can execute a
variety of machining processes (milling, broaching, rolling, marking)
on any surface, but also small assembly and in-process gauging with
automatic compensation of the critical dimensions.
Buffoli turning machines belong to two families.
machines and OMNI-TURN
machines. The first ones address bar turning applications, the second
ones to the production of complex parts or long parts (shafts or similar)
especially in alloy steel and stainless steel.
are precision static bar machines equipped with spindles operating
from opposite directions and, optionally, radially. They are very
suitable for the production of bar stock parts, even for batches of
a few thousand. They feature high productivity and quick change over,
and are ideally suited to just in time production requirements.
machines combine static part transfer
machine processes with rotating part machining processes (such as
long turning operations and/or deep drilling operations). They are
high-productivity patented turning and milling machines in which the
two different areas work multi-task (a transfer area and a vertical
lathe area). They are suitable for the complete machining, in a few
seconds, of complex precision parts (long fittings for flexible tubes
and relevant ferrules, CV joints, crankshafts, shafts for compressors,
etc). Thanks to a Buffoli patent, in these machines the cycle time
is, usually, 1/3 of the longest operation, thus resulting in much
more productivity than any conventional machine or production line.
Customers of ours change over the machine
many times/day, running batches of 300 - 1000 parts
with cycle times of 0.75 - 20 seconds. The combination
of Precision, Productivity and Just in Time production represents
the winning solution provided by the Buffoli machines. Non
rotating part machining (drilling, milling, and also CNC
static turning, threading and profiling) and rotating part
machining are integrated into a versatile, precise and
highly reliable CNC turning and milling system.
