Everything You Need To Know About the Gear Hob Cutters

Gears are used in many types of machinery. These rotating spherical components have cutting teeth, or teeth inserted into gear wheels, etc., which engage one another to transmit torque. The teeth on the two gears have the same shape. Gears make changing the power source’s torque, speed, and direction possible. It has been around for centuries and has contributed to the industry’s significant growth. Have you ever taken a moment to wonder how  make them? The most widely used process in today is called gear clamping. This process is used to create spur gears and helical gears. 

What Is Hobbing?

The machining process used for gear cutting on a machine is called hobbing. The hobbing machine is a special kind of Miller Machine with the teeth of gears that will progressively move for cutting the base material throughout the series. This cutting tool is called the hob. This is a relatively inexpensive way of making gears compared to other gear forming processes and is entirely accurate. That is why hobbing is typically used for gears. Hobbing machines have two skew spindles, one mounted with a work piece and the other with a hob. The angle between the work piece and the hob’s spindle depends on the gear produced. 

What Is A Gear Hobbing Cutter?

A stove is a woodworker’s tool to cut teeth into a blank. The furnace has a cylindrical shape and has spiral-cutting teeth that run the length of the stove. These teeth help in cutting and removing chips. Special hobs are also designed for specific products like sprocket gears. The teeth on the hob have a cross-sectional shape almost identical to the teeth of a rack used for the final product. Hobs generally tend to be single-thread hobs, but it is not uncommon for double and triple-thread hobs to be used to increase the production rate. 

Types of gears made by gearing

Helical gears:

Helical gears are often called dry fixed gears and have a certain degree of customization. That happens because the leading edges of the teeth are not parallel to the axis of rotation. After all, the gear has a curve. The shape of the teeth makes them part of the spiral. It is a good choice for machines requiring high speeds or loads.


A gear is a profile wheel that has teeth or gears. They can be coupled to rails or chains that pass through them. It is different from standard gear because the gears do not mesh directly with each other. Sprockets are often used in bicycles. Motorcycles, cars and other machinery that must transmit rotating motion between the two shafts

Involute Gear:

Involute gear is one of the most popular gear solutions available today. This is because the tooth profile of the involute gear allows for smooth power transmission at the lowest possible speed or torque. The supply the high-strength applications primarily helical involute , in which the tooth threads have different hands.
