External Spline Cutting Tools

This method can be used to produce both internal and external splines of parallel involute or serrated type.

External spline cutting tools.

To select a gear cutter follow these steps. However due to sweepout clearances and tight part features shaping methods are also commonly used. Splines can be either straight cut or helical cut. If worn they can be sharpened and used again.

Determine the pitch of the gear you re cutting. All external spline forms can be produced with the hobbing method dependant upon the limitations of the machine tool and the individual component design. Round to the nearest whole number. All types of external splines can be produced with the hobbing method.

The number of starts of the hob and the number of teeth in the spline determine the ratio that the hobbing machine is geared to produce. Gear pitch no. A cylindrical hob with the mating rack form of the spline to be produced is the cutting tool. Spline cutting with an involute spline cutter or straight side spline cutter is the process of machining internal and external splines onto shafts gears and other mechanical power transmission components.

Tooth profiles of external splines can be cut by shaping hobbing form milling or power skiving. Vardex gear milling tools can be used interchangeably in a wide range of applications in gear spline rack and sprocket manufacturing. The hobbing process typically offers the best balance between productivity and flexibility.
