Gear Hobbing Basics

Gear hobbing is a diverse and wide-ranging process that can be used to create several different gear types: Helical, worm and spur gears are some of the most common, but others are possible as well. It's carried out using a special form milling machine, one that contains a tool known simply as a hob.

The hob is the tool that directly generates the teeth for both gears and splines, and it does so with relative simplicity compared to other gear manufacturing types. It allows for high-volume production of these gear types.

Our subsequent sections will look at the advantages of gear hobbing within the spring manufacturing process and why it's one of the single most common methods utilized in this realm.

Speed and Simplicity

Within the gear manufacturing world, speed is a major factor. Many of the common processes utilized take a relatively long time, limiting both volume of production and turnaround time for immediate needs.

Gear hobbing, however, is one of the faster processes available. A big part of the reason for this is how simple the machine is - it's easy to operate and can usually hob multiple units at once if they're stacked on top of each other. On top of this, hobbing machines require very little maintenance or operational attention while they're working. They allow for high-volume production with quicker turnaround times than most other methods.

Precision and Accuracy

This speed is achieved without any detraction in the precision or quality of the final product. Gear hobbing is done through CNC gear hobbing machines, with automated computers in place to ensure high accuracy in coordination with the operator. Gear hobbing is known to create precise, high-quality gears for a variety of applications.
