RIX Formula SPF helps to boost cutting performance

A time-consuming slitting process can also be eliminated due to the finished surface of the edge material. Manufacturing companies can thus increase the tool life and efficiency of their entire machine train and therefore permanently lower operating costs. Despite the higher acquisition prices for the new generation of saw blades, the use of RIX Formula SPF bi-metal saw blades provides considerable savings potential for cutting. Sägen-Mehring GmbH develops and manufactures bandsaw blades and saw blades and the corresponding circular saws, machine saws, hand saws and saber saws, as well as metal core drilling machines and cutting tools for the metal processing industry and machine tool trade. The products are sold under the RIX, Optibohr and Optipress names. In addition, Sägen-Mehring runs one of the largest CNC tool grinding shops in Germany for repairing cutting tools.

SAGEN-MEHRING GmbH, an international saw blade manufacturer, says its new RIX Formula SPF line achieves higher cutting speeds and feed performance as well as offering more consistent sawing and higher wear resistance. The performance of the RIX Formula SPF saw blade was recently documented in a number of cutting tests with one of Germany’s leading sawing machine manufacturers. The tested blade offered combi-toothing from 0.75 to 1.25 teeth per inch, was 1.6mm thick and 80mm wide. An alloyed case-hardened steel of quality 1.6587 – 18CrNiMo 7-6 according to the DIN EN ISO standard 683-17 with a diameter of 655mm was cut as part of the test series. The RIX Formula SPF saw blade accomplished this in a cutting time of 9.6 minutes with a cutting speed of 84m and a feed rate of 68mm per minute. By comparison, a conventional bi-metal saw blade took 82 minutes with a cutting speed IN recent years Thermatool has continued to play an active part in the metal building and construction sectors worldwide, gaining a strong reputation as a leading supplier of hollow structural section (HSS) HF welding technology. The latest range of Thermatool solid-state, high frequency contact welders have become central to the manufacture of high quality engineered structural sections. Engineered structural sections such as ‘I’, ‘H’, ‘T’ and other asymmetrical shapes can be welded continuously on a specially designed HF welding mill. Recent advances in steel chemistry with the advent of advanced high strength steels (AHSS) and excellent HF weld quality has increasedthedemandforengineeredstructural sections. Thermatool has advanced a proven range of HAZControl Technology welders that offer custom ‘I’-beam producers excellent weld quality in materials not previously available. Thermatool solid-state, high frequency contact welding technology will precision heat and forge weld engineered structural sections at high line speeds with maximum precision, requiring no secondary re-straightening prior to shipment. To satisfy a growing market, Thermatool welding technology has brought about the opportunity to produce a virtually

of 31 metres and a feed rate of only 8mm per minute. Markus Döring, chief executive officer of Sägen-Mehring GmbH in Hockenheim, Germany said: “We achieve the high performance of our saw blades by paying careful attention to the surface finish of the edge material. This also requires sophisticated process technology for the finishing of our cutting edges. Of course, the backing material, and even the toothing of the edge material, also play a role, although they are of lesser importance.” The company says that the coatings applied to the edge material can only come into full effect after the finishing of the cutting edges. The functional surface of the bi-metal saw blade attained in this way provides optimal guidance in the cutting channel, which results in a high red hardness, which in turn allows a higher cutting pressure to be exerted on the material. The result is particularly high wear resistance, top feed performance and high cutting speed.
