Gear cutting Processes

Gear cutting is a very precise and technical process, usually having to cater for customers specific requirements so that the cut of the gear is perfect for the machinery they need it for. Commonly made from metal or plastic means there all multiple different gear cutting process depending on the service that the customer requires.

The most common gear cutting processes used throughout the manufacturing industry are hobbing, broaching, milling and grinding. It is important to understand the difference between these various gear cutting processes so that the right technique and procedure is apply ensuring the highest quality of precision cutting meeting the customers specifications and requirements.

Hobbing :

The hobbing gear cutting process uses a hobbing machine, these are fully automated machines cutting splines and sprockets. These hobbers come in a variety of different sizes this is because they are used to cut all types of gears from small instrument gears to large industrial machinery gears. The teeth of the gear are gradually cut into the gear through a series of cuts made by the hob.

The hobbing process for gear cutting is most commonly used for creating helical gears and spurs. This hobbing process for gear cutting is a relatively quick compared to other gear cutting processes meaning that it is commonly less expensive.

Broaching :

The broaching gear cutting process is mainly used for precision machinery and cutting some of the larger gears. This process uses a toothed tool called a broach which is used to remove material when gear cutting. This process is usually used for high quantity production runs as it can be one of the more expensive compared to other gear cutting processes.

Milling/Grinding :

This process of gear cutting uses rotary cutter to remove material, the milling machine covers a variety of different operations from small singular parts to big heavy-duty industrial machinery. The main difference between the milling cutter and other gear cutting processes mentioned is the cutter in the milling is moved perpendicular to its axis so the cutting edges of the tool continuously cut into and exit the gear meaning greater precision when cutting.
