General machining process of precision gears (for reference)

General machining process of precision gearsThe instructions are as follows, for reference and understanding. If you are unclear or related to processing requirements, you can consult EP free of charge.

XNUMX. Raw material processing:

Use a material cutting machine to cut the material to the corresponding thickness as needed, and cut it into a noodle shape.

XNUMX. Quenching treatment:

The first quenching process is performed to adjust the hardness of the steel. It is heated in a high temperature furnace at 800 degrees Celsius for about 3 hours. After being taken out of the high temperature furnace, it is slowly cooled in cold oil. After it is completely cooled, it enters the machine tool processing stage.

XNUMX. Machine tool processing:

After the heat treatment, the material is loaded on the machine tool to mill out the shape. This intermediate product is generally called the wheel blank of the gear, and then it enters the gear cutting process.

XNUMX. Gear cutting process:

Use the gear hob to cut the gear blanks, load the gear blanks on the gear cutting machine, use a micrometer to first center, and then fix the blanks and start cutting.While pouring lubricating oil on the wheel blankMachining gearOn the teeth.Finally, a wheel blank with a gear shape is obtained after the preliminary processing is completed.

XNUMX. Secondary quenching:

After the secondary quenching is completed with the high-frequency heater, the hardness is confirmed on the wire and then sent to the next section.

XNUMX. Grinding process:

Use a surface polishing machine to polish the surfaces that need to be processed or assembled, and then polish the teeth.Change the shape of the terrazzo, and further process and polish the teeth of the gear.The tooth part has been polished and some special curves are milled in the gear part.

Seven, inspection process:

Check the shape of the gear teeth to see if there is any deviation in the center position of the interval between the teeth, etc., quantify and keep records.

Some gears that require ultra-high precision will be further polished using the latest polishing machine after the above-mentioned polishing process to further improve the accuracy.
