Bushing parts as an important part of mechanical manufacturing, its surface quality directly affects the performance and life of the entire mechanical equipment. This paper mainly focuses on the mechanical polishing process of bushing parts to discuss, analyze its technical points, process and considerations in the actual application, in order to provide reference and reference for the processing of bushing parts.
With the rapid development of modern industry, the processing quality of mechanical parts requires more and more high. Bushing parts as a connection, support and guidance and other functions of the key components, its processing quality, especially the surface quality of the entire mechanical equipment has a critical impact on the operational performance. Mechanical polishing as an effective means to improve the surface quality of bushing parts, with high processing efficiency, stable processing quality and other advantages, has been widely used in production practice.
Second, the technical points of mechanical polishing of bushing parts
- Polishing fluid selection: polishing fluid is a key factor in the mechanical polishing process to play the role of grinding and lubrication. According to the bushing parts of the material, surface roughness and processing requirements, a reasonable choice of polishing fluid, can improve the polishing effect.
- Polishing wheel selection: the hardness and elasticity of the polishing wheel has a great impact on the polishing effect. Generally speaking, high hardness, good elasticity of the polishing wheel is suitable for high-precision, high hardness of the bushing parts polishing.
- polishing speed and pressure: polishing speed and pressure are important factors affecting the polishing effect. Reasonable control of polishing speed and pressure can make the surface of the bushing parts to achieve the desired polishing effect.
- Optimization of polishing process parameters: according to the material, shape and processing requirements of the bushing parts, by adjusting the polishing process parameters, to achieve efficient and accurate polishing.
Third, the process of mechanical polishing of bushing parts
- workpiece preparation: the bushing parts for cleaning, deburring and other pretreatment to ensure that the surface of the workpiece is clean, no corrosion.
- polishing solution preparation: according to the material of the bushing parts, surface roughness and processing requirements, choose the appropriate polishing solution, and stirred evenly.
- Polishing wheel installation: install the polishing wheel to the polishing machine, and adjust the speed, pressure and other parameters of the polishing wheel.
- Polishing: Put the bushing parts into the polishing liquid and polish them with the polishing wheel. During the polishing process, pay attention to observe the changes on the surface of the workpiece and adjust the polishing speed, pressure and other parameters in time.
- Cleaning: After polishing is completed, the bushing parts are cleaned to remove the polishing liquid on the surface.
- check: the polished bushing parts for quality inspection to ensure that the surface quality meets the requirements.
Fourth, the bushing parts mechanical polishing in the practical application of the notes
- the use of polishing liquid: polishing liquid in the use of the process should pay attention to stirring evenly to prevent precipitation. At the same time, according to the actual processing situation in a timely manner to replace the polishing fluid.
- maintenance of the polishing wheel: the polishing wheel will wear in the process of use, to be replaced and adjusted in a timely manner. At the same time, the polishing wheel should be regularly cleaned and maintained.
- workpiece clamping: in the polishing process, to ensure that the bushing parts of the stable clamping, to prevent uneven polishing due to workpiece jumping.
- operation safety: operators in the polishing operation, to wear good protective equipment, pay attention to safety.
The mechanical polishing process of bushing parts has an important role in the actual production. Through the reasonable choice of polishing fluid, polishing wheel, optimize the polishing process parameters, can effectively improve the surface quality of the bushing parts, extend the service life of mechanical equipment. In practical application, we should pay attention to the selection and use of polishing fluid, polishing wheel maintenance, workpiece clamping and operational safety, etc., to ensure that the quality of bushing parts polishing at the same time, improve production efficiency.
