1、 Problems with the gear hobbing machine itself

When machining gears with a gear hobbing machine, if there are problems with the machine itself, it is easy to cause poor tooth profile. 

Common problems include insufficient cutting force, unreasonable cutting parameter settings, and damage to cutting tools.

2、 Workpiece material issues

When machining gears with a gear hobbing machine, the material of the workpiece is also an important factor leading to poor tooth profile. Perhaps the workpiece material is too hard to form a smooth tooth profile during the gear hobbing process,

Or the uneven hardness of the workpiece material may result in irregular tooth profiles after gear processing.

3、 Tool issue

The cutting tools of the gear hobbing machine contribute greatly to the machining of the tooth profile, and if there are problems with the tools, it can also lead to poor tooth profile. Common tool problems include passivation, wear, and uneven wear

4、 Processing environment issues

When machining gears with a gear hobbing machine, the machining environment is also an important factor affecting the tooth profile. If the working environment of the gear hobbing machine is unstable or the working temperature is unreasonable, it can also lead to poor tooth profile. Meanwhile, if the machining fluid is not pure enough or the viscosity of the machining fluid is not appropriate, it will also affect the machining quality of the gear.

In summary, there are many reasons for poor tooth profile in gear hobbing, which may be related to problems with the gear hobbing machine itself, workpiece materials, cutting tools, and machining environment. To solve this problem, measures such as using more advanced processing equipment, optimizing workpiece materials, regularly inspecting and replacing cutting tools, and maintaining a stable processing environment can be taken.
