Frequently asked questions

What is a hob?

A gear hob, by design, could be described as a series of rack cutters arranged in a spiral pattern on a cylinder. They are the preferred cutting tool for mass production, as they can cut gears much faster than traditional rack cutters. They are designed to be used in a hobbling machine to cut the specific shape and size of teeth, providing the necessary clearance and tooth form.

Can hobs be used for internal gear cutting?

No, hobs are typically used for external gear cutting. For internal gear cutting, other methods such as shaping or broaching are commonly employed. These methods involve specialised tools and processes designed specifically for cutting gears with internal teeth.

What is the gear cutting process?

It is the process of creating teeth on gears using specialised tools. This process is necessary to generate the gears' teeth to the required size, shape, and profile.

What are gear cutting tools?

Gear cutting tools like hobs, milling cutters, and shaping cutters. These tools are used to accurately cut teeth on gears during the cutting process.

What is the maximum size that can be produced?

The maximum size that can be produced depends on the specific machine and tooling used. Different machines and tooling have different restrictions on the size and diameter of hobs they can accommodate.

What are sprocket hobs?

These are special hobs designed for producing teeth on sprockets.

What are worm gear hobs?

These are cutting tools used for machining the teeth of worm gears.

What are the benefits of using a coating?

Coatings provide increased tool life, improved surface finish, reduced friction, and improved chip evacuation.
