Bending & Tube Manipulation
Freeform bending
WITH the Nissin Freeformbender produced
by Neu Machinery it is possible to bend
different radii tubes and profiles in three
dimensions without tool change. This is due
to a patented tooling in combination with a
CNC control system. Radii can follow each
other without straight length in between,
and can be in different planes. The machine
can produce bent tubes with homogeneous
wall thickness.
Using a mandrel, thin-walled pipes can
be bent on the Nissin Freeformbender, up
to a diameter of 90mm. The smallest radius
that can be achieved is close to 2DR. The
system can bend not only round pipes, but
also flat oval tubes and asymmetric profiles.
The Easy Programming software
for Windows has functions that include
preview, mirroring and rotation, and in
combination with the optional measuring
arm makes the handling of the machine
easy. Bent parts can be compared and
corrected automatically, and 3D CAD data
can be used directly to prepare a bending
program for the machine. The latest
Freeformbenders are available with three,
five or six simultaneous axes, combined
with automatic loading and unloading
devices. The development of a seventh
axis will be completed in the near future.
The product range of Neu Machinery
includes machines for chipless endforming
of tubes, sawing and cutting machines
for nearly all materials, and customised
automation technology for tube
manipulation.
