The common faults and troubleshooting methods of gear hobbing machines mainly include the following aspects:

1. Unstable machining accuracy, unstable quality, and dimensional deviation: These problems are usually caused by factors such as machine tool structure design, workpiece clamping, and machining tools. The solution includes basic machine tool maintenance work, such as timely tool replacement and cleaning of the machine tool surface,

And adjusting cutting parameters or selecting higher quality machining tools to improve machining accuracy and quality issues, solving size deviation problems by checking factors such as workpiece clamping direction.

2. Unstable machine tool speed, insufficient coolant, and control system failures: These problems are usually caused by design issues of the machine tool equipment itself. It is necessary to regularly check whether the machine tool coolant is sufficient and whether the machine tool control system is working properly to ensure the normal use of the machine tool.

3. Excessive machining load: This problem is usually caused by excessive cutting depth or slow machining speed of the machine tool, thereby increasing the load on the machine tool. To solve this problem, it is necessary to adjust machining parameters, replace more wear-resistant tools, and appropriately reduce the depth of single machining.

4. Tool wear: Long term use can lead to tool wear, affecting machining accuracy and efficiency. The solution includes regularly checking the wear of cutting tools, replacing severely worn tools in a timely manner, and adjusting the installation angle and cutting parameters of the tools to extend their service life.

5. Loose workpiece: During gear shaping, loose workpiece may cause a decrease in machining accuracy or damage to the workpiece. Ensure that the workpiece is securely installed and fixed using suitable fixtures. At the same time, regularly check the looseness of the workpiece and adjust the fixture or re fix the workpiece in a timely manner.

6. Tooth profile error: may affect the meshing accuracy and transmission effect of gears. The solution includes ensuring correct tool installation, reasonable cutting parameter settings, strengthening tool grinding and calibration work, and for gears with large errors, post-treatment processes such as heat treatment and grinding polishing can be carried out.

8. Cooling system malfunction: If the cooling system malfunctions, it can cause an increase in cutting temperature, exacerbate tool wear, and affect machining quality. The solution is to regularly check the working condition of the cooling system and promptly clean impurities and dirt in the coolant.

In summary, different solutions are needed for different faults. Ultimately, it is necessary to pay full attention to the quality and performance of the machine tool, and carry out regular maintenance and upkeep to ensure the safety, reliability, and long service life of the CNC gear hobbing machine equipment
