NEW PRODUCTS – NEW PRODUCTS – NEW PRODUCTS
A SIMULTANEOUS LAUNCH!
Mills CNC, the exclusive distributor of
Doosan machine tools in the UK and
Ireland, has recently introduced two new
Doosan 5-axis machining centres into the
market.
The two machines - the DVF 6500
(650mm diameter table) and the larger
capacity DVF 8000 (800mm diameter table) -
are from the same stable as the highlypopular
Doosan DVF 5000 machine
successfully launched in the UK and Ireland
18 months ago.
The new DVF machines share many
similarities.
Both machines are compact and have a
rigid and stable structure for increased
accuracies, improved surface finishes and
greater process reliability. They are also fast,
boasting impressive 45m/min rapid rates,
and are equipped with powerful, oil-cooled,
directly-driven BT40 spindles (up to
22kW/18,000rpm) that deliver excellent
cutting performance, irrespective of
whether 3 + 2, 4 + 1 or full 5-axis
simultaneous machining is the order of the
day.
The machines also feature servo-driven
automatic tool changers (up to 120 tools)
with a 1.3 second T-T-T changeover time
that increase the machines’ flexibility, roller
LM guideways that deliver increased speed,
accuracy and reliability, and direct-drive
rotary tilting tables (A-axis = +120/-120
degrees; C-axis = 360 degrees).
The DVF 6500 and DVF 8000 machines
can be supplied with a choice of control
(Fanuc 31iB5, Heidenhain TNC640 or
Siemens 840D with ShopMill software), and
are supplied with thermal compensation
systems (spindle and structure) and a longlife,
grease lubrication system. A Collision
Protection System can also be supplied as an
option.
Both machines can also be supplied with
a range of different automation solutions
that increase their productivity, and enable
manufacturers to take advantage of
unattended and lights-out operations.
The DVF 6500 and DVF 8000 have
different-sized travels (DVF 6500 = 750mm x
785mm x 600mm: X-, Y- and Z-axis; DVF
8000 = 1000mm x 900mm x 685mm: X-, Y-
and Z-axis), and different table loads - (up
to 1000kg and 1400kg respectively).
Within the DVF 8000 range a specific
‘Turning’ model can be specified. The DVF
8000T, with its integrated function, has the
same technical specification as the DVF 8000
in most respects except for a lighter
maximum table load (700kg), and a faster C-
axis feed rate (600rpm).
Says Tony Dale, Mills CNC’s Technical
Director:
“The depth and breadth of Doosan’s
already highly successful 5-axis machining
centre range is second to none. The
introduction of these two new models will
be of interest to component manufacturers
looking to improve their productivity and
make ‘one-hit’ machining a reality.”
