    Eco-friendly and efficient gear dry grinding machine

    With the SG 160 Skygrind, Samputensili announces the first gear dry grinding machine in the world. The state-of-the-art process carried out by the machine reportedly completely eliminates the need for cooling oil during the hard finishing grinding of the toothed gear after heat treatment.

    Samputensili will be spotlighting the SG 160 Skygrind at EMO Hannover 2017, which is billed as the world's first gear dry grinding machine.

    The grinding process is split into two main passes, namely for roughing and finishing. For the roughing process, skive hobbing is applied, whereas worm grinding is implemented for the finishing process. According to the Italian manufacturers, the machine removes around ninety percent of the stock allowance with the first pass using a hobbing tool, which has the advantage of not heating the workpiece excessively. Subsequently, with the second finishing pass, a grinding wheel then removes the remaining stock without causing the problem of overheating the workpiece, thus resulting in a completely dry process. Moreover, the innovative structure of the grinder with two spindles actuated by linear motors and the use of more channels simultaneously is said to ensure a chip-to-chip time of less than two seconds. The machine allows cycle times for the finishing of gears that are seen as ideally suitable for the automotive industry and at a lower cost compared to traditional manufacturing solutions. Additional benefits include the very small footprint and a lower cost of investment for auxiliary equipment. Moreover, by totally eliminating the need for cutting oils, the machine is claimed to be particularly eco-friendly.
