There are two basic types of spline rolling machines using flat racks in use today. These spline rolling machines are producing a variety of splines, threads, grooves, and clutch housings around the world. The main difference between the two types of rollers is the way that the main slides are driven and synchronized. One type of roller uses two hydraulic cylinders to drive the slides while, timing racks and a timing gear keep the slides synchronized. The other type of spline roller uses two hydraulic piston motors which are connected to to a rack and pinion to drive the slides. These machines use a gear train to keep the slides synchronized. There are a few machines out in the world that use the hydraulic piston motors with the timing racks and gear.

Spline rolling machines can range from very simple to very complex tooling set-ups. This section will deal with the fundamentals of spline rolling machine set-ups as well as a discussion on complex set-ups.

The physical installation of the racks is not a difficult task. Here is a step by step outline of the procedures involved, starting with the lower rack box.

Once the set-up procedures and installation are complete, a piece part can be rolled. However, some set-ups such as part change or new set-ups may require some additional adjustments before a part can be rolled.

A spline can best be described as a method of transmitting torque. There are many different applications for splines in industry today. These applications vary from the simple to the complex. An example of a simple application is an automotive flanged axle.

The materials that can be rolled are as varied as the splines themselves. However, non-ferrous materials generally have not been successful for rolling splines. Almost all of the carbon steels have been rolled at one time or another.
