The cleaning techniques for CNC gear hobbing machines are as follows:

1. Clean all surfaces, dead corners, and protective covers of the machine tool, and check for external missing parts. Requirements: All parts should be clean, free from oil stains, yellow robes, and rust.

2. Clean and change the exchange gear, differential gear division, and feed change gear rack. Requirement: Change and exchange gears, differential gears, dividing gears, feed change gears, gears, spline shafts, shaft sleeves, worm gear pairs, and other components to be clean.

3. Clean the column, tool holder, and tailstock, and adjust the inclined iron. Requirements: The components such as the column, tool holder, tailstock, each lead screw, guide rail, and cutting mechanism should be clean, and the clearance between the inclined iron should be appropriate; The handle is securely locked and reliable.

4. Clean the CNC gear hobbing machine workbench and the guide rail of the gear hobbing machine body. Requirement: Clean the workbench, bed guide rails, screws, nuts, and other parts.

5. Clean and repair each oil hole pipeline, and check the oil pressure gauge. Requirements: The oil mark is eye-catching, the oil circuit is unobstructed, the oil quality and reclamation meet the requirements, and the oil pressure gauge is easy to use; The filter, filter screen, and oil tank are clean, and the oil tools are complete.

6. Clean and repair the cooling pump, filter screen, and cooling liquid tank. Requirement: Clean all parts and remove sediment and debris from the cooling liquid tank; The pipeline is smooth, firm and tidy.

7.
