Gear Hobbing
Gear hobbing refers to the process of using a broaching machine to cut the grooves, known as gear teeth, into a component. Gear hobbing machines are capable of cutting gears with different numbers and varying sizes of teeth. Gear hobbing is used to make teeth for many different kinds of gears, including spur, crown, helical, and worm.
Like all broaches, gear hobbing machines are hydraulic cutting tools used to cut holes in metal, wood, and plastic materials. Broaching teeth come in many different sizes and spacing configurations, depending on the part that is being broached. There are two different kinds of broaches: internal broaches, which are used to cut through the material, and external broaches, which are used on the surface. External broaches are used in the gear hobbing process.
Gear hobbing as a process provides many advantages, including a high productivity rate, economical and efficient operation, accuracy, close tolerances, versatility, and smooth finishes. Gear hobbing machines are used to make components used in various industries, including the aerospace, automotive, construction, hardware, and manufacturing sectors.
