Cutting Blue is using the Doosan DNM 6700 to machine high precision and high value rigid machine that delivers speed, high
components for a range of customers operating in the motorsport and general engineering
sectors
footprint and a good-sized working envelope
(to handle a wide range of different-sized
parts).
“We also needed a machine with a
Heidenhain 640 control (our preferred VMC
platform) to be able integrate with our
existing machines and program database.
“We had looked at acquiring a Doosan
DNM 4500 at the start of the year but had
postponed the decision – temporarily as it
transpired.
“However, the increase in demand and
the need for a swift delivery (caused in part
by the impact and effects of the pandemic)
– combined with a great purchase price we
were able to negotiate with Mills for a new
DNM 4500, meant that the investment was
given the go ahead.”
Since being installed, the DNM 4500
has been used to machine a range of
components for customers operating in the
motorsport, lm, leisure and industrial
sensor sectors.
These components, machined in small
to medium batch sizes and from a variety
of materials that include aluminium,
stainless steels, titanium and engineering
plastics, often exhibit tight tolerances (i.e.
down to a few microns in some instances)
and superior surface nishes (Ra 0.1μm).
POPULAR FOR PRECISION
Doosan machines are proving a popular
choice for precision component
manufacturers in the UK and Ireland, as
Birmingham-based Cutting Blue has also
invested in its rst Doosan 3-axis vertical
machining centre from Mills CNC.
The large capacity Doosan DNM 6700
machine has been installed at the precision
engineering rm’s 2,000 square foot facility
in Saltley, where it is being used to machine,
in mainly small batch sizes high precision
and high value components for a range of
customers operating in the motorsport and
general engineering sectors – to name but a
few that it operates in.
Cutting Blue began life as an engineering
consultancy rm, but owner and managing
director Piotr Parobczy turned it into a
manufacturing company in Spring 2020, as
says the pandemic outbreak had a
detrimental effect on the availability of
contract work and proved to be the
“catalyst” he was waiting for.
“From my background and experience the
company would not be a ‘jack of all trades’
operation but instead would offer specialist,
high-precision machining (milling) services to
customers typically operating in the high-end
motorsport, automotive and aerospace
sectors,” he adds.
Parobczy decided to invest in a new
machining centre rather than a used one
and after scouring the market and
approaching a number of machine tool
manufacturers, he opted for the Doosan
DNM 6700 through Mills CNC, who he
says “took time to understand the
business and the type of work that
would be undertaken: they worked
collaboratively with me to identify the
optimum machine tool solution”.
Understanding the type and size of
components and typical materials to be
machined, the part accuracies and
surface nishes that would be require
and the volumes/batch sizes to be
machined – resulted in Cutting Blue
ordering the Doosan DNM 6700.
The Fanuc controlled DNM 6700
installed at the company’s facility is a highly
accuracy and unrivalled process reliability.
It is equipped with a 18.5kW/12,000rpm
directly-coupled (high speed) spindle, a
1500mm x 670mm work table with a
1300kg maximum table load, a 30-position
ATC, roller LM guideways (all axes) and
thermal error compensation.
The machine was also supplied with a
Blum TC50 workpiece touch probe and Blum
ZX Speed IR tool setting probe.
Parobczy says: “The DNM 6700, with its
large worktable, provides much needed
capacity, capability and exibility (now and in
the future) enabling us to machine large or
multiple smaller parts in one set-up.
“Although still early days, I am delighted
with the DNM 6700 and am already looking
at investing in second Doosan machine.”
TAKING THE NEXT STEP
Another rm investing is JWA Tooling (JWA) –
a specialist provider of high precision
manufacturing solutions – which has
purchased a new Yamazaki Mazak ( www.
is.gd/9JVWKH ) British-built CV5-500
simultaneous 5-axis machining centre
(pictured bottom left on page 35).
The Leicester-based precision engineering
company’s capabilities, include precision
CNC milling, turning and wire EDM and it
follows a previous installation of a Mazak
VCN-530C vertical machining centre to meet
customer demand for larger batch sizes.
