Turned parts


More Information



Machined polycarbonate coupling. Customer requested flexible coupling for medical application. Part is essentially a spring with little rigidity and C axis machining requirements. The challenge is to remove material in a predetermined fashion to meet the final design without compromising the material. Part must finish complete off of the machine, no secondary operations.
