Diameter Rolling

It is sometimes necessary to add an operation of rolling on the parts when they cannot be centerless grinded. This operation is added for example when machined parts are too small or when the required diameter tolerance is too tight. Rolling permitting to reach a diameter tolerance of 1 micron, instead of 3 microns for centerless grinding. Rolling process also allows to improve potential cylindrical or circularity defaults and to give an impeccable surface finish.
