Spline rolling is one of the fastest and most accurate methods of manufacturing high production, splined components. The advantage of spline rolling is that no metal is removed and it is a cold forming operation. Hence, the microstructure improves to provide better strength and wear resistance. The splines are highly finished by rolling operations. Spline rolls can also be reground several times. Cnc spline rolling machine model jarryd-20 is highly sophisticated and can roll components up to 2.5 module splines. One of the unique features of this machine is force feeding the job into the spline rolls and gradually forming the splines by generation method very accurately. The other features of this machine are: it uses pc based controls and sophisticated ac. Variable drives which can control all machining parameters very accurately; machine set-up is very easy, pitch matching is controlled electronically; high precision ball screws; ground gears and bearings are special characteristics of this machine. Simple user/operator friendly menu driven programmes are used for sttting up a component. It has high resolution positive feedback arrangement for accurate and consistent comnponents. Job changeover is very easy, old programme can be stored in the vast bank of memory available with jarryd-20.
