Gear hobbing is a machining process used to create gears by cutting teeth into a cylindrical workpiece. This method employs a specialized tool called a hob, which rotates and moves along the workpiece to shape the gear teeth accurately. It is commonly used for producing spur gears, helical gears, and other gear types. The process is efficient and can produce gears in large quantities with high precision. Gear hobbing is widely used in various industries, including automotive and manufacturing, due to its ability to create complex gear profiles quickly and cost-effectively.
