Principles of parts mechanical processing technology

Part machining is a relatively complex work, which requires very high accuracy. In the context of science and technology, the part machining industry has achieved very significant development, and the processing method has also undergone great changes.

The machining of parts is a relatively delicate work. In the process of designing the machining process of parts, designers must follow certain principles, so as to improve the rationality of the design scheme.

These principles mainly include the following aspects:

(1) Principle of positioning datum of parts. In the process of machining parts, the first step is to locate the parts, which is also the most basic work content. This work is very important. If there is any deviation in the positioning work, it will directly affect the effect of parts machining. In the numerical control lathe, the main content of the positioning reference work is to adjust the position of the airport, and at the same time, adjust the angle of the props to create a good premise for the follow-up work. In the process of parts machining, it is usually necessary to carry out a rough machining to make a rough model. In this process, the positioning datum also needs to use rough datum, which can effectively improve the efficiency of parts machining. In the process of fine machining, it is necessary to adopt the corresponding positioning reference mode and the refined positioning reference to improve the machining accuracy of parts and meet the actual processing requirements. Therefore, in the process of locating datum, different positioning modes should be selected according to the different machining modes of parts, so as to achieve the purpose of improving the machining effect of parts.

(2) Principles to be followed for surface processing of parts. Part surface machining is the key content of part machining. Due to the increasingly advanced mechanical equipment, the requirements for the surface of mechanical parts are very high. In the process of machining, it is necessary to select a reasonable part machining method according to the accuracy, size and other parameters of the parts, so as to meet the actual survival needs. If there are special requirements for the surface of the part, the part needs to be treated separately to ensure that the processed part is consistent with the design standard.

The surface processing of parts shall follow the principle of economy. The principle of economy is the most basic principle, which is also a powerful means to improve the efficiency of enterprises. After determining the surface parameters of the parts, employees usually have a variety of processing processes. They should choose the most economical one to reduce the processing cost on the basis of ensuring the quality of the parts. In addition, in the process of part processing, the accuracy of the part surface usually has certain requirements. The staff should use reasonable technology to ensure the accuracy of other parts, but do not pursue the accuracy too much, just need to meet the design standards, which can save a lot of time and money.

The principle of coordinating production types. In the process of parts machining, employees should classify the parts to be processed, sum up the same type of parts, and use the same program to process them. For example, in parts machining, a large number of parts need to be processed, and then these parts are classified. The parts with low accuracy requirements and those with high accuracy requirements are summed up separately, and then processed with different equipment. In this way, the efficiency of parts machining can be effectively improved, and a lot of money can be saved.

To sum up, parts machining is a relatively complex work. In the process of this work, certain processes must be used, so that the machined mechanical parts can meet the actual use standards. When machining parts, we should select different processing methods and processes according to various parameters such as part accuracy, ensure the standardization of the part machining process, improve the efficiency of the part machining, and produce high-quality mechanical parts.
