More and more people tend to choose precision parts and ordinary parts. As a component of machinery, why are precision parts more popular? What are the benefits of achieving precision part machining? Below, our chief engineer will introduce to you:
During the processing of parts, various factors can easily lead to their own defects. For example, the appearance does not meet the standard, the scope of use is limited, and the existence of these defects will inevitably bring certain problems to the use of the parts. To overcome these problems and unleash the unique value of the parts, precision machining is the best choice.
Choosing precision parts for machining not only effectively improves material quality and precision, but also greatly enhances the durability of the parts, promoting the overall quality of the machinery. Precision machining also benefits the dimensional accuracy of the parts. Therefore, the most direct effect is to achieve interchangeability of the parts, thereby increasing their wear resistance and service life.
It is precisely because of the aforementioned advantages that precision part machining is so popular. When assembling equipment, more suitable fields can also be adopted to maximize its value. From this perspective, it is necessary to attach importance to the precision part machining process.
After processing various different parts, we can obtain parts that are more suitable for ourselves. Therefore, in order to better serve oneself and maximize the value of these products, precision machining is an important link that many cannot do without.
What is mechanical processing?
Mechanical processing is a process of changing the external dimensions or properties of a workpiece using machining machinery. It is divided into cold processing and hot processing according to the temperature state of the workpiece being processed. Generally processed at room temperature without causing any chemical or phase changes in the workpiece, it is called cold processing. Generally, processing above or below room temperature can cause chemical or phase changes in 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, while hot processing commonly includes heat treatment, calcination, casting, and welding.
In addition, cold and heat treatment is often used during assembly. For example, when assembling bearings, the inner ring is often cooled in liquid nitrogen to shrink its size, the outer ring is appropriately heated to enlarge its size, and then assembled together. The outer ring of the train wheel is also heated and placed on the substrate to ensure its strong bonding during cooling.
