Cutting, Sawing & P rofiling T echnology
courtesy of a 2,500W laser source. Off-
line programming software specifically
developed for the machining of tubes
creates new programs quickly and easily,
typically less than 10 minutes from drawing
to finished part.
The machine is provided with Siemens
control that allows the operator to manage
all the main functions, including program
downloads. Fast setup and changeover
times (around three minutes) mean short
batches can be managed as cost-effectively
as longer production runs.
In addition to sheet metal processes such
as CNC punching, presswork, folding
and rolling, and its expertise in laser tube
cutting and profiling, Hydram also offers
MIG/TIG welding of mild, stainless steel
and aluminium.
Precision CNC machining is also available,
with powder coating of parts that require
painting prior to final assembly and delivery.

The decision to purchase the LT 712D tube
laser was based in part on the performance
and reliability of the BLM Dynamo CNC
tube bender and the new machine’s 8.5m
tube length processing capacity.
“We were impressed by the build quality
of the machine, its off-line programming
capability, the service and support provided
by BLM Group UK Ltd, and the
experiences of other end-users,”
said Mr David Greatorex, operations
director at Hydram.
“Where we would previously have
used several machines to process
tubular components, we now use
the tube laser and have eliminated
inaccuracies and work-in-progress. All
of this has enabled us to take cost out
of the job because it is not just about
cutting faster, it is about revisiting
the entire production process from
design to delivery of the completed
component.”
The BLM Adige LT 712D is equipped
with a Siemens Sinumerik 840D
CNC and can process round, square,
rectangular and flat-sided oval
section tube up to 152mm diameter,
BLM Group UK Ltd has delivered a new
BLM Adige LT 712D CNC tube laser to
Hydram Sheet Metalwork, UK.
With over 30 years of experience in
subcontract manufacturing, Hydram
has built a reputation for quality sheet
metal components, assemblies and light
fabrications produced at its 70,000ft2 factory.
Tube laser contributes to sheet metal component
manufacturer’s strategy
blades for extremely high cutting rates.
Vertical and horizontal clamping on the
infeed side and horizontal clamping on
the discharge side assure square and
burr-free cuts.
The heavy-duty tube and bar end deburring
machine is loaded automatically by means
of an interlinking cut piece transfer system.
Burrs are simultaneously removed from
both ends with tubes being deburred on
the ID and OD. Interchangeable support
rails are available to rotate rectangles or
shapes.
The machine has a simple horizontal
and vertical adjustment of the brushes
as well as lateral adjustment for the
cut piece length. Standard sawing and
deburring lengths of 40", 80", and 120"
are available.
