External Spline Cutting Tools

Determine the pitch of the gear you re cutting.

External spline cutting tools.

The hobbing process typically offers the best balance between productivity and flexibility. Of teeth 2 od. Gear pitch no. Splines can be either straight cut or helical cut.

This method can be used to produce both internal and external splines of parallel involute or serrated type. 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. All external spline forms can be produced with the hobbing method dependant upon the limitations of the machine tool and the individual component design. 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.

Vardex gear milling tools can be used interchangeably in a wide range of applications in gear spline rack and sprocket manufacturing. If worn they can be sharpened and used again. Also known as involute gear cutters these tools work with a milling machine to create 14 pressure angle spur gears. Round to the nearest whole number.

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. A cylindrical hob with the mating rack form of the spline to be produced is the cutting tool.
