How are P/M gears processed?

As we all know, powder metallurgy gear is a kind of gear parts widely used in various fields at present. It can reduce cutting or no cutting, reduce processing steps, reduce the waste of many raw materials, and make the precision of gear higher. Therefore, powder metallurgy gear has now become the main application in various high-grade automobile, ship and motorcycle gears. Do you know how to process the powder metallurgy gear? Here is a brief introduction of the Zhongwei Precision Editor:

Powder metallurgy gear

Machining process of powder metallurgy gear:

1. Preparation of mixture

First, the powder raw materials are prepared, and then the powder is mixed to make raw materials.

2. Pressed powder forming

The raw metal powder is pressed into the desired style of powder metallurgy gear by powder metallurgy pressing equipment.

3. Sintering treatment

During the sintering process, the powder particles become metallurgical gears with certain porosity through a series of physical and chemical processes such as diffusion, recrystallization, fusion welding, combination, dissolution, etc. The sintered gears can be used.

4. Post processing procedures such as precision

Through the methods and steps of fine pressing, rolling, extrusion, quenching, oil immersion, etc., the powder metallurgy gear has higher precision, hardness, wear resistance and better performance.

The content introduced above is the machining process of powder metallurgy gears. In fact, the processing flow of P/M gear is similar to that of other P/M parts. However, if the traditional machining processing technology is used, the steps and processes will be much more complex and the cost will be higher. Therefore, many industries now choose to use powder metallurgy to process gears. The gears processed by powder metallurgy have good size consistency, stability and high precision, which can achieve mass processing and production with higher production efficiency and lower cost.
