RINGSAW® is Reika’s new generation of
machine tools for the cutting of tubes,
bars and profiles with diameters ranging
from 10 to 610mm and wall thickness from
1 to 150mm. The machine is operated
completely electro-mechanically without
hydraulics, and is therefore oil-free.
The cutting process is either dry,
with mini-coolant or flood emulsion. No
additional foundation work is necessary
(apart from machine fixations), as the
machine bed is totally oil-free and
designed as a closed cold water draining
and reservoir area.
The chip conveyor can be integrated
directly into the machine bed. The
RingSaw can be delivered with an optional
automatic tool changer, and features a
totally enclosed machine design with
safety protection cover for full operator
safety and environmental protection.
During the Tube 2010 show in
Düsseldorf, the RingSaw was one of
the few continuously producing machines
on show. The machine relentlessly, and
almost silently, cut bearing blanks from
high grade, heavy wall, large diameter
feed stock.
Visitors were said to be surprised
by the basic motions of the machine,
with the cutting ring whirling around the
stationary workpiece, resulting in claimed
tool cost savings of 50 to 80 per cent
compared to conventional carbide saws
and a performance of 30 to 60 per cent
higher.
Reika’s Andreas Zimball stated, “We
are talking about high six-digit amounts
that can be saved year by year. That
means investment cost for the RingSaw
can be paid off in a short time from tool
cost savings alone.”
While the RingSaw is a newly designed
line for the cutting of tubes, profiles and
bars, its design is based on decades
of experience in intelligent technology
and know-how, shown by a considerable
number of similar concept lines, already
well established on the market. The new
concept is based on a project originating
from Reika’s German competitor, Procon.
Reika, a member of the Graebener Group,
acquired the Procon-Lines in 2009.
Based on the existing Procon-Whirling
lines and using Graebener Group’s
engineering capacities, Reika developed
the RingSaw.
According to the first case studies
and reports covering the RingSaw, a
well-known German manufacturer of
roll bearing rings achieved savings in
operating cost of approximately 80 per
cent on the Reika machine, compared to
a conventional carbide saw. Key features
of the material are: 100Cr6 pre-tempered,
tube diameter 73mm, and 12.6mm wall
thickness.
