Made from 4605 low-alloy steel, the three parts are made close to net shape, with only a few secondary operations performed to achieve close tolerances. The output shaft is a complex part with three small holes at 120deg inter crossing each other, and thin wall thickness in the cover part and close GD&T makes them good parts for MIM .As MIM is able to produce 3 parts of 5 part assembly and make the supply chain lean, MIM is a sustainable process. These 3 parts get assembled in the Dremel tool. This is called as “Quick Change Assembly” since one can change any tool bit within seconds. The tool will run at 35000 rpm.
