Spline Rolling Machine is using Rack die/cutter instead of Cylinder thread rolling die; many different types of splines, serrations, oil grooves, worm gears, screws, knurls, threads and similar forms can be rolled in individually or in combination in just 3 to 7 seconds.
The Spilne Rolling Machine is inherently accurate, with surface finishes of Ra: 0.05µm to 0.15µm obtainable. Spline Rolling is best suited for long production runs or intermittent runs of a variety of parts. It's the fastest and most economical method of producing involute toothed forms.
The PFR-LV Series spline rolling machine is Profimach's new cost-conscious workhorse. Simple, powerful, unidirectional hydraulic cylinders offer the quality, and repeatability that is inherent to the cold forming process. The Models 500, 800 and 1000 offers these advantages and all with a lower initial investment.
The model PFR-LV’s affordability does not translate into limited choices. Machine configurations of 500, 800 and 1000 accommodate rack/tooling lengths of 800, 1000 and 1500 , respectively. (See table below for more details). Further customization is available for automatic parts loading, multiple rack/tool configurations, and quick-change fixtures. The PFR-LV line accepts a variety of electrical power inputs, utilizes a self-contained oil or water based coolant system, and is of rigid cast iron design. And all Profimach spline rolling machines are built for ease of service.
Choosing a Machine
Machine choices usually “start with the part”. The part’s characteristics will typically determine the size machine needed. Our expert engineers can quickly and accurately assess your part’s requirements, guiding you to a machine ideal for your needs while avoiding the cost-overages of “too much machine.” One more way Profimach experience saves you money.

The chipless coldforming of profiles such as involute splines (straight or helical), spiral serrations, oil grooves, and threads only takes seconds with the Profimach coldforming process and is significantly faster than cutting processes. In addition, coldformed workpieces have a higher load capacity and a better surface finish and accuracy. Involute splines and other profiles can be produced very quickly and precisely with this process. The high precision coldforming racks roll and press the required profile into the workpiece during the coldforming process. The material is displaced and flows into the free spaces of the racks. The workpiece is pressed twice during one rotation, i. e. forming takes place in a series of steps. The height of the ground profile in the forming rack increases progressively into the forming area. This causes each rack tooth to press slightly deeper into the material than its predecessor. After reaching the full profile depth, the form gets optimized in geometry and surface finish in the calibration zone
The accurate mold clamping module makes the mold replacement easy and fast, without the need for tooth alignment.
Variety of combined functions of mold clamping module possible, special "WIDE MOLD" Machines give multi-combined tooling posibilities. You can Roll different surfaces in one time passing
It has the special function that the workpiece needs to be oriented or has incomplete teeth.
Unique forming principle and precise positioning mechanism can process the spline to the nearest of the shoulder, no need to retract the tool
