Development of New Gear Cutting Machine by Mitsubishi Heavy Industry
Demand for high efficiency and accuracy equipment for machining of various gears including transmission gears, at low cost has been increasing in the automobile industry. Mitsubishi Heavy Industry (MHI) with its world’s first dry cutting gear production system using no cutting fluid back in 1997, has led the industry with diverse gear cutting machines and cutting tools. IN response to market demand, MHI has introduced a new gear grinding machines suitable for volume production of gears for up to 150 mm in diameter. The new ZE15B gear grinding machine is equipped with a newly developed workpiece changer resulting in shorter amount of time required for changeover, plus the twin tailstock model is capable of reducing non-operational time to just five seconds. The shorter high efficiency grinding has been achieved through an increase in machine rigidity and by adopting a 30 percent faster grinding wheel with the speed of maximum 6000rpm. Read more
