Tube B ending, Hydroforming & End-Fo rming
To cope with the growing market
demand, Dutch-company Buigstaal
Tube Bending Alkmaar has significantly
increased its capacity with the purchase
of a new Schwarze-Robitec CNC 80 TB
MR tube-bending machine. With this
new CNC 80, Buigstaal aims to increase
its capacity by 50 per cent in this tube
size range.
The Schwarze-Robitec bending machine
operates by the transport bending
principle, which increases the bending
performance and improves the accuracy
of the product dimensions. The machine
bends tubes up to 88.9mm diameter
and has the capability of multi radius
bending. With delivery in May 2007, the
machine is due to be fully operational by
July 2007.
Part of the Van der Wel Group, Buigstaal
offers just bent tubes up to complex
assembled tube products for the
automotive, defence, energy and industrial
markets.
At the end of 2006, the company received
an ISO 9001:2000 certificate from Bureau
Veritas.

Large family of mandrel tube
bending machines
transfluid, Germany, has launched the
DB650ST-SPS mandrel tube bender, part
of a family of ten mandrel tube bending
machines. These machines all feature
the same three axis ‘SPS’ user friendly
numerical control. Bending capabilities start
from tube sizes as small as 6mm and range
up to 220mm OD.
Consistent accuracy is possible with the
automatic bending and digitally controlled
positioning of rotation and length. All
models are designed with a special
recessed tool shaft to accomodate small
bend radii.
The transfluid DB650ST-SPS is a semi-
automatic mandrel tube bending machine
complete with an upgrade for CNC-style
operation. It offers forward, back and
rotational motorised positioning to remove
the need for mechanical stops.
All 3-axis data is input using a touch screen
control, with instant retrieval of stored
programme data by part or job number.
