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.

Tooth profiles of external splines can be cut by shaping hobbing form milling or power skiving. 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. Splines can be either straight cut or helical cut. Round to the nearest whole number.

Gear pitch no. A cylindrical hob with the mating rack form of the spline to be produced is the cutting tool. All types of external splines can be produced with the hobbing method. Each tool has a different number of flutes to achieve a variety of different cutting diameters depending on the application.

However due to sweepout clearances and tight part features shaping methods are also commonly used. Also known as involute gear cutters these tools work with a milling machine to create 14 pressure angle spur gears. Of teeth 2 od. Vardex gear milling tools can be used interchangeably in a wide range of applications in gear spline rack and sprocket manufacturing.

All external spline forms can be produced with the hobbing method dependant upon the limitations of the machine tool and the individual component design. To select a gear cutter follow these steps. The hobbing process typically offers the best balance between productivity and flexibility.
