The machining of brass pins is a common and important manufacturing process. Brass pins are commonly used for mechanical connections, positioning, and transmission, and their machining process includes the following main steps:
Preparation of raw materials
Select brass bars of appropriate specifications and quality to ensure that the material has good cutting and mechanical properties.
Selection of processing equipment
Select suitable machine tools according to processing requirements, such as lathes, milling machines, drilling machines, etc.
Processing steps
Turning: Turning the outer circle to achieve the specified diameter and surface roughness.
Milling: If there are features such as flat surfaces and keyways, they can be machined through milling.
Drilling: used for machining center holes or other holes.
Grinding: For surfaces with high precision requirements, grinding is carried out to improve surface quality and dimensional accuracy.
Precision control
Strictly control dimensional tolerances, such as diameter and length, to ensure precise assembly of brass pins with mating components.
Ensure positional tolerances such as cylindricity and straightness to meet motion and positioning requirements during work.
surface treatment
Perform deburring treatment to make the surface smooth and avoid scratching the mating parts.
If necessary, perform surface coating treatment to enhance corrosion resistance or improve appearance.
The advantages of CNC machining are mainly reflected in the following aspects:
High precision: CNC machine tools are controlled by computer programs and can process with precision to the micrometer level or even smaller tolerance range. This high-precision machining is crucial for manufacturing parts that require precision fit or high precision.
High efficiency: Once CNC machine tools are programmed and set up, they can automatically complete the machining process without the need for manual intervention. This greatly improves production efficiency, reduces production costs, and allows for faster response to market demand.
Repeatability: As the machining of CNC machining tools is based on computer programs, each machining can ensure the same accuracy and results. This repeatability is particularly important for mass production, ensuring product consistency and stability.
Flexibility: CNC machine tools can adapt to different machining needs by modifying or rewriting programs. This means that the same machine tool can be used to process parts of different shapes, sizes, and materials, improving equipment utilization and flexibility.
Complex machining: CNC machine tools can handle complex geometric shapes and curves, including the machining of three-dimensional parts. This ability gives CNC machining significant advantages in manufacturing complex parts.
Reducing human errors: The reduction of human intervention during CNC machining reduces quality issues caused by human errors. All processing parameters are controlled through programs to ensure consistency and accuracy in processing.
Improving the working environment: The automation of CNC machine tools reduces direct contact between workers and hazardous processing equipment, thereby improving the working environment and enhancing worker safety.
Reduce skill requirements: Although CNC programming requires certain skills, the operation of CNC machine tools requires lower skill requirements for workers compared to traditional manual processing. This makes it easier for businesses to find and retain qualified workers.
Easy to integrate: CNC machine tools can be integrated with other automation equipment (such as robots, automated material handling systems, etc.) to achieve a higher degree of automation and intelligent production.
Material saving: CNC machining can accurately remove materials according to the actual needs of the parts, reduce waste, and improve material utilization.
