Hobbing process is inexpensive and quite accurate as compared to other gear forming processes. It is made in use for a wide range of parts and quantities.

This gear cutting process is widely used for creating spur and helical gears. Maximum number of gears is cut by this process.

In the hobbing process, a hobbing machine is used which bears two non-parallel spindles, one of which is mounted with a blank work piece and the other with the hob.

The angle between hob's spindle and the work piece spindle may vary. It depends on the type of the product being produced.

Modern hobbing machines are known as hobbers. Hobs may be single threaded, double threaded or triple threaded, double and triple threaded hobs are used to increase the production rate but their accuracy level decreases as compared to single threaded hobs.

Hobs may be of the following types such as roller chain sprocket hobs, worm wheel hobs, spline hobs, chamfer hobs, serration hobs, spur and helical gear hobs, straight side spline hobs etc. Milling cutters are used to cut tools in milling machines or machining centers. They are used to remove materials from the machine by their movement. Milling cutters comes in different shapes and many sizes.

Several standard shape milling cutters are used in the industry. The milling cutters may be of different types such as end mills, slot drill, roughing end mill, ball nose cutter, slab mill, side and face cutter, involute gear cutter and many others.

Sometimes many people feel confused while selecting a milling cutter, although it's not a difficult task. The cost of the job is a combination of the price of the tool.

High speed steel cutters are inexpensive and have short life. Cobalt steel cutters are little improved from the HSS and can run 10% faster. Carbide tools are expensive than steel and has long life also. These tools run much faster.

Larger tools can remove the material much faster than small tools.

Gear & sprocket milling cutters are very important cutting tools. Gear cutting process includes broaching, hobbing and machining. Gears are made from metal, plastic and wood. On the other hand chain sprocket hobs are also important tools of hobbing process. These industry tools are portable as well as stationary and are base of the industry, they offer a lot of advantages and makes task and working in the industry easier.
