the heart of this range is a new complex SPF-coating and a multi-step procedure to improve cutting edge coatings. In this way, higher temperature resistance and red hardness can be reached. Higher cutting speeds, larger feed values and outstanding cross section qualities are the result. This is particularly the case with very hard steels, austenites and high-temperature alloys. Extended application tests were carried out at a big saxon steel distributor, which revealed a number of advantages of this range. Economic and efficient cutting speeds and cut rates could be achieved, close to the values and even better than those reached by TCT band saws. Even high-tensile steels can be accurately cut with a cutting speed of more than 60- 70m/min. On a cutting length of 700mm, a tolerance of less than 0.1mm is possible.In addition, these high cutting values had no negative effects on cross sections. Finely structured and spotless cross sections are of considerable advantage to the user. Sägen-Mehring – Germany Fax : +49 6205 2098 444

Increasing the performance of bi-metal band saws

Sägen-Mehring, Germany, has launched a new range of metal band saws, branded RIX-Formula SPF, to service the industry’s increasing requirements for higher performance metal sawing machines and cutting tools. Higher specific cut rates are now required in the industry, with more cm² of cut area per minute and higher tool life, resulting in precise and spotless cross sections. The ultimate aim is to achieve less cost per cut. In the past a degree of ground has been covered to achieve such developmental aims. For cutting tools such as metal band saws, the advancements are well documented. Bi-metal band saws are usually made from modern alloyed cutting materials (ie high speed steels). The backing bands feature a high resistance against tensile stress, alternating bending load and torsional stress. However, further improvements of this component have become increasingly difficult. Setting and tooth geometries are well developed and are, in many cases,

specifically conceived for predetermined application areas, mainly for wear-resistant steels and alloys. Further improvements were expected from the use of tungsten carbide as cutting material. However, it appears that this breakthrough has not been widespread in its application. Nevertheless, it is widely believed that band saws with tungsten carbide tips can be used economically. This is especially the case if robust sawing machines with high drive capacities are available, and if shortest possible cutting times are the top priority. In the search for new and efficient ways to improve performance, due to existing experiences with precision cutting tools, coating processes and cutting edge treatments were developed. It took time until technically passable methods were introduced for the coating of ‘coil ware’, with efficent and easy treatment methods for saw teeth. These technical developments have been met by the RIX-Formula SPF range of metal band saws from Sägen-Mehring. At
