The two main types of thread rolling machines are planetary and rotary. The planetary rolling machine (also known as rotary rolling mill) keeps the screw blank still, while multiple rolling machines roll around the blank. A planetary rolling machine produces planetary roller screws - screws for precision applications requiring linear motion. The machines used for aluminum thread rolling are similar to those used for screw rolling of steel and brass. In addition, for spline rolling machine advantages, Spline rolling machine can adapt to various tool settings. A machine can roll dozens of parts with different spline sizes; The rolling spline has excellent surface finish.
