The working principle of hobbing machine and hobbing machine

Working principle of gear hobbing machine:

Hobbing machine is a machining process that gradually cuts the tooth profile through cutting methods. The specific steps include: first, determining the modulus,

 number of teeth, and other parameters of the gear, and selecting the appropriate rolling cutter. Install the workpiece on the hobbing machine,

After the rolling cutter is matched with the workpiece, it gradually cuts the target tooth profile by rotating and pushing along the tooth profile of the workpiece. During the rolling process,

 the hobbing machine will control the motion trajectory of the rolling cutter to ensure good contact with the workpiece surface,

Ensure cutting quality and accuracy. By multiple rolling cuts, gradually complete the cutting of the entire gear tooth profile.

Working principle of gear hobbing machine:

Gear hobbing machine is also a machining process that forms tooth profiles one by one through cutting methods.

 The specific steps include: first, determining the modulus, number of teeth, and other parameters of the gear, and selecting the appropriate gear hobbing tool. Install the workpiece on the gear hobbing machine,

After the gear hobbing tool is matched with the workpiece, it cuts the target tooth profile one by one along the tooth profile of the workpiece through rotation and propulsion. 

During the gear hobbing process, the gear hobbing machine will control the motion trajectory of the gear hobbing tool to ensure good contact with the workpiece surface,

Ensure cutting quality and accuracy. By repeatedly hobbing, gradually complete the cutting of the entire gear tooth profile.

The difference between hobbing machine and hobbing machine:

1. Application scope: Hobbing machines are mainly used for processing spur and helical cylindrical gears, as well as worm gears, and are suitable for mass production.

   Gear hobbing machines are suitable for processing cylindrical gears with internal and external meshing, especially for processing small gears in internal gears and multiple gears.

2. Processing efficiency: Gear hobbing machines have high processing efficiency and are suitable for mass production;

 However, gear hobbing machines have relatively low processing efficiency and are suitable for small batch and single piece production.

3. Applicable scenarios: Hobbing machines are suitable for large-scale production, while hobbing machines have more advantages in processing internal gears and multi gear sets.
