Hobbing is a process which is performed with the help of gear hobs. There are so many gear hobs manufaturer in the market and the competition in the tool industry is increasing day by day. Although many kinds of hobbing tools are used and inserted blade gear hobs are also among them.
Hobbing is a machining process that is used to make gears, splines and sprockets. Hobbing machine is a special type of milling machine. The teeth of the hobbing machine progressively made cuts by a cutting tool which is called a hob.
This process is not as expensive as compare to other processes. This process offers feature of accuracy thus used for large range of parts and quantities.
This process is widely used in cutting helical gears and spurs. Maximum numbers of gears are cut in the hobbing process than any other process. This process is quick and inexpensive.
A hobbing machine is used In the process of hobbing, this machine consists two non-parallel spindles. One of them is mounted with ablank work piece and other with the hob.
The angle may vary between the hob spindles and the work piece. It depends on the type product which is going to be produced.
In the work piece, five teeth can be cut in a single time. Modern machines are coming in many sizes and are fully automated these machines are known as hobbers.
Each gear hobbing machine includes chuck and tailstock that holds the work piece or a spindle. Hob is a cylindrical tool that bears helical cutting teeth.
There are some special hobs also which are designed for special gears such as splines and sprockets. Following finished types of goods are manufactured from hobbing process like cycloid gears, helical gears, splines, spur gears, worm gears, ratchets, involute gears.
gear hob manufactures designed numerous tools for the hobbing process. Inserted blade gear hobs are manufactured in the range of 20 to 32 modules, HSS material is used for the blades and the body is designed from carton steel.
Gear hobbing is in the trend from thousands of years and benefitting humans in numerous ways. New methods of hobbing are evolving as the technology is getting advance. These new methods are producing gears which are much fast and effective.
