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.
