Largest Linsinger circular saw
THE circular sawing machine KSA 2200
DPD from Linsinger, Austria opens up
new dimensions in cutting steel billets
as it can cut 800mm steel in just four
minutes. The first machine of this type
has just been supplied to South Korea
by the Austrian technology expert.
The latest milestone in sawing
technology measures 2.3m: this is the
diameter of the KSA 2200 DPD saw
blade, which is probably the largest
constructed carbide vertical circular
sawing machine for steel billets. Recent
innovations allow it to combine the huge
performance capacity of a machine of
this size with unbeatable efficiency. “We
are therefore now preparing to succeed
in a market segment that was previously
reserved for band saws,” explained
Linsinger CEO Hans Knoll.
Of the number of technical innovations
Linsinger has incorporated in this high
performance saw, a particular one
stands out: double power drive (DPD) is
a completely new gear concept with two
drive trains that has been fully developed
in the Linsinger R saw competency
centre. It optimises transmission and
guarantees a completely precise cut
with its clearance – and all of this at
extremely fast cutting times: the KSA
2200 DPD only needs four minutes to
saw through a steel billet with a 800mm
diameter (material 42CrMo). “This
shows that a new era really has begun.
DPD is without a doubt one of the most
important industry innovations of the
past decades,” emphasises Mr Knoll.
DPD is just as much a Linsinger
patent as the LINCUT® disc miller, with it
the “mega-saw” is equipped. Its cutting
plates are not soldered, but screwed
on. They can be individually and simply
replaced at any time as required. The tool
can even be reequipped when installed;
costly transport to a sharpening centre
is unnecessary. A sharpening centre is
no longer required.
With Lincut®, Linsinger has one of the
most efficient solutions for machining
difficult materials right through to
titanium. The system is already running
on more than 40 machines worldwide
and has long proven itself in three-shift
operation. “The competitors are, at best,
only at the stage of developing similar
processes,” is the information which
comes out from user groups.
