Why is it so hard to find a satisfied camshaft bushing supplier? Even it is in China.
Maybe you need to know some details for camshaft bushing material machining and surface treatment.
The difficulty of machining camshaft bushings is mainly reflected in the following aspects:
- Material selection: Camshaft bushings are usually made of bimetallic rolling, with an inner alloy layer and an outer steel back. The material selection of the alloy layer has a great influence on the difficulty of processing, such as tin-based, lead-based alloys, copper-based alloys or aluminum-based alloys. Different materials have different hardness, wear resistance and processing performance. Choosing the right material is the prerequisite for ensuring processing quality.
- Precision requirements: The camshaft bushing has high requirements for dimensional accuracy, shape accuracy and position accuracy, such as outer diameter, wall thickness, chamfer size and angle, etc. The guarantee of these accuracies requires precise processing equipment and strict quality control.
- Surface quality: The surface roughness of the camshaft bushing is strictly required. For example, the outer surface roughness Ra should be less than or equal to 1.25µm, and the inner surface roughness Ra also has specific requirements, which requires the use of appropriate cutting parameters and high-quality tools during the processing.
- Heat treatment and metallographic structure: Camshaft bushings may need to be heat treated during processing to meet the requirements of hardness and metallographic structure. The control of heat treatment process has an important influence on the performance of the final product.
- Oil hole and oil groove processing: The oil holes and oil grooves on the camshaft bushing play an important role in lubrication and cooling. Their processing accuracy and position accuracy have a direct impact on assembly and performance.
- Press-fitting process: For the press-fitting process of the finished camshaft bushing, it is necessary to ensure that the bushing does not deform excessively during the press- fitting process , and at the same time ensure that the oil hole is aligned with the oil hole of the body, which requires precise positioning and press-fitting equipment.
- Quality control: Strict quality inspection is required during the processing of camshaft bushings, including material inspection, hardness inspection, metallographic structure inspection, size and tolerance inspection, surface roughness inspection, etc., to ensure product quality.
In summary, the difficulty of camshaft bushing processing lies in material selection, precision control, surface quality assurance, heat treatment, oil hole and oil groove processing, press fitting process and quality control, etc. These factors jointly determine the difficulty of camshaft bushing processing and the performance of the final product.
Another difficulty is quantity, if you are a new brand owner or a wholesales distributor, there are so many engine models, you can not order mass quantity for every model, how to solve?
