The working principle of a gear shaping machine mainly involves the interaction between the gear shaping cutter and the workpiece

A gear hobbing machine is a machine specifically designed for machining gears. Its core principle is to use a gear hobbing cutter to cut gears into several teeth. During the cutting process, the gear hobbing cutter and the workpiece rotate around their respective axes, forming the involute tooth profile of the gear.

This cutting motion is necessary to form the involute tooth profile of the workpiece, and at the same time, the up and down reciprocating motion (main motion) of the gear cutter forms the tooth profile.

The entire machining process also requires the gear cutter to perform radial feed (cutting) motion relative to the workpiece, which can be divided into one to multiple times according to specific circumstances.

In addition, the gear hobbing machine also needs to be equipped with positioning devices, feed devices, bearings, spindles, motors, and other components. The most important of these is the motor, which drives the rotation of components such as the spindle, bearings, and gears, allowing the gear hobbing cutter to perform precise cutting,

The feed device is also very important, its function is to achieve different machining requirements for gears by adjusting the feed rate, thereby ensuring the machining accuracy of the gear shaping machine.
