TURNING CRITICAL CAPACITY
Turning news and products in brief
Following the launch of the new brand of Vulcan machine tools,
the Engineering Technology Group (ETG) ( www.is.gd/0PHXhL ) has
launched the new TC200 turning centre – the most compact machine
in the TC range of seven variants with a 200mm diameter chuck size.
Developed to increase speed and precision, the model
is a single spindle and single turret lathe with
a 45-degree slant bed construction to ensure
maximum stability whilst ensuring swarf is effectively
removed from the work envelope.
This ergonomic design allows users to maximise
the heavy-duty cutting potential of the machine
whilst undertaking uninterrupted batch or series
production without continually opening the envelope
to remove chips.
The TC200 is available in four variants to meet
The TC200 is the smallest and
most compact machine in the
expansive TC range
the needs of small component turning operations.
The base model TC200 is the entry-level solution with a single spindle
and single turret.
As a base model, the TC200 has a swing over bed of 460mm, a
maximum turning diameter of 280mm, a spindle speed range of 25 to
4200rpm and a spindle bore of 61mm diameter; that when combined
with the ETG bar feeding solutions can deliver a cost-effective
For manufacturers looking to reduce secondary operations,
ETG can supply the TC200M variant. This machine provides the
opportunity for live tooling stations on the turret for engineers looking
to increase their capabilities.
The TC200 is also available with an ‘L’ variant, the TC200L – the
long bed version that extends Z-axis travel from the standard 490mm
to 740mm. ETG is offering the TC200 Series in four variants – the
TC200, TC200L, TC200M and the TC200ML.
Mills CNC ( www.is.gd/OIjyom ) - the exclusive distributor of Doosan
machine tools in the UK and Ireland - has introduced a new range of
large capacity, multi-tasking mill-turn machines into the market.
The Puma SMX 5100L series, the largest in Doosan’s SMX range,
has been designed and built to handle large, heavy workpieces found
in the aerospace, energy and oil and gas sectors - and machine them
to completion in a single set-up.
5100L range with the largest machines having chuck sizes up to
21”, a maximum turning diameter of 830mm and a maximum turning
length of 3050mm.
SMX 5100LS and SMX 5100LSB machines are equipped
with high-torque, built-in (left and right) spindles (up to
37kW/2400rpm) with 0.0001° resolution on their C-axes
for high precision contouring. SMX5100L and SMX
5100LB models feature a programmable, servodriven
tailstock for precision machining.
All four models are supplied with a powerful and
versatile B-axis milling head (+/- 120° stroke) that
features the Capto C8 quick-change tooling system and is
powered by a 37kW motor that rotates at 10,000rpm.
The roller gear cam mechanism that drives the B-axis
eliminates backlash and is highly rigid, capable of
outputting torque of up to 2700N-m.
SMX 5100L machines’ productivity and performance are further
optimised by their fast rapid rates (40m/min), their (520mm) Y-axis
capability and their heavy-duty high-precision roller LM guideways.
The machines are also equipped with servo-driven tool changers
(up to 120 tools), with the machines’ ATCs also having their own
touch screen operation panel for ease of use, ef cient job set-ups
and improved process reliability. Long boring bar and long tool
magazines are available.
Japanese CNC mill-turn centre manufacturer Citizen Machinery has
announced improvements to three of its Cincom sliding-head models,
all designed to shorten cycle times and raise productivity when
producing components from 32 mm diameter bar and larger. They are
available in the UK and Ireland through subsidiary company Citizen
Machinery UK ( www.is.gd/X2aUTF ).
The company’s agship M32 model, which can produce parts
from bar up to 38 mm in diameter with cutters in a gang toolpost
with B-axis, a 10-station turret and a back tool post with Y-axis, has
gained the manufacturer’s low frequency vibration (LFV) chipbreaking
capability on the main spindle.
In line with Citizen Machinery’s systematic rollout of LFV on all its
Cincom sliding-head turn-mill centres, as well as on one xed-head
Miyano lathe, the 32 mm bar capacity L32 slider has also bene tted
from the chipbreaking technology. It already had LFV on the 3.7 / 7.5
kW main spindle but now boasts the same on the 2.2 / 3.7 kW sub
Turn-milling of components up to 32 mm diameter bar with
the extra productivity bene ts of LFV is now also possible on the
nominally 25 mm capacity Cincom D25-VIII, as an expansion kit is
being offered to enable the lathe to machine the larger size of bar in
both guide bush and non-guide bush modes.
The machine is equipped with 12 CNC axes including
independent Z2-axis movement in addition to X2 and Y2 on the rear
gang toolpost. A 135-degree swivelling B1-axis has also been added
to the X1 and Y1 motions of the front tool post.
There are four different models in the SMX
The Puma SMX 5100L series has been designed and built to handle
large, heavy workpieces typically found in the aerospace, energy
and oil and gas sectors
