Cutting line helps to reduce tool cost

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.
