Eco-efficient prototypes and concepts for gear grinding processes

Since the efforts of SAMPUTENSILI to try to reduce the energy consumption during the grinding process, an holistic approach has been taken in consideration. The total energy during the working cycle of the ring gear provided by Fiat has been evaluated and split in different component as the cutting oil filtering & cooling device, pure grinding process, dressing cycle, oil mist filtering device.

This has been evaluated for the state of art cycle based on the actual cycle used in Fiat workshop with a different brand machine and later on for the various modification applied on the tools (number of starts and technical specifications), on the cooling nozzle design and on the cutting parameters. Important energy consumption reductions have been gained in all the different items studied succeeding a total saving of 38%.
