Automatic tube and pipe cutting machines RTA 35 and RTA 75 (manual feed >)

Cut-off tubes and pipes chipless and with low burrs
The tube and pipe cutting machines RTA 35 and RTA
75 cut tubes and pipes chipless and with low burrs
(see pictures on the bottom right).

The diameters handled range from 2 to 76 mm with
wall thicknesses between 0,4 and 3 mm.

Various materials can be treated, e. g. steel, high-
grade steel / stainless steel, Al-alloys, other non-
ferrous metals, etc.

The knife-lifetime depends on the materials to be cut,
however, ranges between 20 and 30.000 cuts.

RTA 35

tube diameter:   2 to 24 mm (35 mm)
wall thickness:  0,3 to 1,8 mm
material:           steel, non-ferrous metals
cycletime:         up to 1900 parts/hour

RTA 75

tube diameter:  2 to 76 mm
wall thickness: 0,4 to 3 mm
material:          steel, high-grade steel,
                      non-ferrous metals
Cycle time:      up to 1700 parts/hour

The supply of the raw materials to the cutting
machine, in most cases 6 m rods, is automatically
performed either via a 'bundle loader' or an 'in-
clined table magazine'.

Using the bundle loader a whole tube bundle will
be used placed in belt loops. The individual tube
rods are separated and supplied automatically
to the cutting machine.

Cutting the tubes / pipes with our cutting
machines RTA 35 and RTA 75 is a chipless
process.

In order to make a maximum use of the individual
tubes 2 or 3 different lengths are cut out of one
tube.

The cut pieces are received by a sorting unit and
placed - sorted by length - into a magazine.

The first cut and also the final piece are sorted out
separately. If requested, one can operate the
machine without first cut - this material saving
possibility is freely selectable via the operator's
display.

We can produce different lengths of tube
parts - nearly any size is possible.

When working with coils - e. g. copper soft or hard,
Al-alloys, steel - an equalized speed between
uncoiler and cutting machine is of great impor-
tance.

Only then a smooth working cycle can be guaran-
teed.

This is solved by using a specially developed equa-
lizing roll, which actuates a driven uncoiler.

The tubes will be straightened before cutting. 18
straigthening rolls are available for this purpose. The
rolls - which are hardened and polished - calibrate the
tube from a slightly oval diameter into the nominal
diameter. If requested soft copper tube material can
also be hardend during straightening.

After cutting the tubes with the cutting machine a
direct interlinking with further processing machines
can be made., as e. g. closing the tube ends, pun-
ching of the outer tube, etc. (please see also tube
end conditioning)
