NEW!
Both spindles of the air driven
TPP are adjusteble to the thick-
ness of the pipe wall or plate
thickness. Also speeds are ad-
justable. Call or email us for

IN recent years increased world demand for
higher tensile materials including austenitic
and ferritic grades of stainless steel has
created the need for a more reliable cutting
solution, as precision cutting of stainless
steel tube has always been fraught with
difficulties.
To satisfy this challenge, Thermatool
engineers have introduced a series of
strategic design enhancements to its range
of Alpha Flying Shears.
One such example has been the
introduction of aircraft-grade aluminium for
use on the latest die-sets, where increased
strength-to-weight ratio – several times
greater than that of steel – has significantly
improved operating performance, reliability
and overall cutting efficiency.
The latest Alpha Flying Shears also benefit
from fully automated lubrication of the
entire cutting system. Automatic lubrication
of the die-set has also served to reduce
wear and improve blade life by helping to
maintain correct blade alignment longer,
thus reducing mill downtime.
The latest generation of modular die-sets
have been re-designed to reduce vibration,
thereby improving blade life while shearing
higher tensile materials including austenitic
and ferritic grade stainless steels.
Central to the Alpha die-set design is the
patented, horizontal, double-cut scarfing
mechanism, which is rack and pinion
driven and designed to deliver a smoother
transition through the entire cutting cycle,
a significant improvement on former cam-
driven systems.
The latest generation of Alpha shears
also utilise AC servo accelerator systems,
proven to deliver millions of cut cycles with
cut length accuracy up to ±1mm.

Cutting and
bevelling of
tube sections
High-speed shearing technology
PROTEM’S CTA model is designed for
production or prefab workshops, and allows
cutting and bevelling of tube sections. The
cutting is square and the bevel angles are
precise and the cold machining process
gives a clean surface finish.
The tube to be cut is kept stationary by the
machine’s outside clamps, while the tool
bits mounted on a rotating plate are put into
rotation around the tube to perform the cut.
While cutting, the machine performs bevelling
on both ends. However, this radial cutting
principle does not allow the performing of any
counterboring or de-burring.
