Among precision parts and ordinary parts, more and more people tend to choose the former. Also as an integral part of the machinery, why are precision parts more popular? What are the benefits of completing precision parts processing?
During the processing of parts, due to the influence of various factors, it is easy to cause certain defects in itself. For example, the appearance is not up to standard, the scope of application is limited, etc. The existence of these defects will inevitably bring certain problems to the use of parts. In order to suppress these problems and bring out the unique value of parts, precision parts processing is the best choice.
Choosing precision parts processing can not only effectively improve the quality of materials, the accuracy of parts, and give full play to their functions, but also greatly improve the durability of the parts, and improve the quality of the entire machine. Precision machining is also good for improving the dimensional accuracy of parts, so the most direct effect is to make the parts interchangeable, thereby increasing the wear resistance and service life of the parts.
It is because of these advantages that precision parts machining is so popular. When the equipment is assembled, it can also be used in a more suitable area, so that its value can be maximized. From this point of view, we must pay attention to the processing of precision parts.
After processing various parts, we can get more suitable parts. Therefore, in order to make these products work better for themselves and give full play to their ultimate value, many of them are indispensable for the important link of precision machining.
What is machining?
Machining is a process of changing the external dimensions or properties of a workpiece with processing machinery. According to the temperature state of the workpiece to be processed, it is divided into cold working and hot working. It is usually processed at room temperature and does not cause chemical or phase changes of the workpiece, which is called cold working. Generally, processing at a state higher or lower than normal temperature will cause chemical or phase changes of the workpiece, which is called hot processing. Cold processing can be divided into cutting processing and pressure processing according to the difference in processing methods. Hot processing commonly includes heat treatment, forging, casting and welding.
In addition, cold and heat treatment is often used in assembly. For example, when the bearing is assembled, the inner ring is often cooled in liquid nitrogen to shrink its size, and the outer ring is properly heated to enlarge its size, and then assembled together. The outer ring of the wheel of the train is also set on the substrate by heating, and the solidity of its separation can be ensured when it is cooled.
