Among precision parts and ordinary parts, more and more people tend to choose the former, which is also a part of machinery. Why are precision parts more popular? What are the advantages of precision parts processing? The following is a brief introduction:
Parts in the processing process, due to various factors, it is very simple to lead to its own shortcomings. For example, the appearance is unqualified and the scope of application is limited. The existence of these shortcomings will inevitably bring some problems to the use of parts. In order to overcome these problems and bring the unique value of parts into play, precision parts processing is the best choice.
The selection of precision parts for processing can not only effectively improve the material quality of parts and give full play to the effect of precision parts, but also greatly improve the durability of parts, improve the quality of the whole machine. Precision processing is conducive to improving the dimensional accuracy of parts. Therefore, the direct effect of Z is to make parts interchangeable and increase the wear resistance and service life of parts.
It is precisely because of these advantages that precision parts processing is so popular. The assembly of equipment can also be used in more suitable fields, giving full play to its value. From this point of view, we must pay attention to the processing of precision parts.
After processing different parts, we can get more suitable parts. Therefore, in order to make these products better serve themselves and bring their value into play, it is unnecessary for many of them to carry out precision machining as an important link.
What is machining?
Machining is the process of changing the size or function of a workpiece with a processing machine. According to the temperature of the workpiece, it can be divided into cold processing and hot processing. Generally, processing at room temperature will not cause workpiece chemistry or phase change, which is called cold processing; generally, processing at or below room temperature will cause workpiece chemistry or phase change, which is called hot processing. According to different processing methods, cold processing can be divided into cutting processing and pressure processing. Heat processing is commonly used for heat treatment, calcination, casting and welding.
Cold and hot processing is also often required during assembly. For example, when assembling bearings, they tend to have inner rings, reduce their size and expand their outer rings to a suitable size under the cooling of liquid nitrogen, and then assemble them together. The outer rings of wheel trains are also set on the substrate by heating, that is, they can be combined to ensure their cooling.
