Sliding Bearing Processing Flow

Detailed explanation of sliding bearing processing process:

1. Raw material preparation The first step in sliding bearing processing is to select suitable raw materials. Steel materials are usually used, such as high carbon steel, low carbon steel, etc. When selecting materials, you need to consider the load, friction, wear and other factors that the bearing will bear to select appropriate materials.
2. Turning processing Turning processing is one of the key steps in the production of sliding bearings. The purpose is to process the round material into precise shapes and sizes to meet the required quality standards. It is also one of the most basic processing techniques in bearing manufacturing. Turning operations require sophisticated processing equipment and technology to ensure processing accuracy and surface quality.
3. Grinding In the process of sliding bearing processing, grinding is one of the necessary steps. The purpose is to perform subsequent processing on the processed bearing surface and improve the surface quality while ensuring the processing accuracy. Commonly used grinding methods include surface grinding and ball grinding, which require repeated processing processes to achieve the required accuracy.
4. Copper layer plating During the processing of sliding bearings, the bearing surface needs to be plated with copper after turning and grinding. This is to improve the wear resistance and corrosion resistance of the bearing. The thickness of the copper layer needs to be set according to the requirements of the bearing, usually tens of microns.
5. Oil holes and grooves During the use of bearings, oil lubrication is required to reduce wear and friction, and to reduce the operating temperature during high-speed rotation. Therefore, during the bearing manufacturing process, oil holes and grooves need to be created to facilitate the filling of lubricating oil and the circulation of lubricating fluid.
6. Quality Inspection, Marking, and Packaging After the sliding bearing is processed, strict quality inspection is required, including dimensional accuracy, surface quality, copper layer thickness, oil hole groove, etc. After passing the test, it will be marked and packaged for easy identification and management during transportation and storage.
