In the absence of precision machinery, the traditional processing methods used by mechanical parts machinists not only affect the production speed of the parts, but also significantly reduce the manufacturing quality of the parts. However, we know that efficiency and quality are the basis of business survival, especially when small and medium-sized enterprises increase their orders, the production volume must also reach a considerable standard. Currently only precision machining can meet this standard in our society. The processing of precision mechanical parts depends on advanced manufacturing technology, efficient and high-precision automated production equipment. Therefore, the equipment is equipped with the first priority.
Precision parts machining technology is the process of specifying the machining processes and operating methods for the parts. Under specific production conditions, the more reasonable process and operation methods are written into the process documents in a prescribed form and used to guide on-site production after approval. The process flow of precision machined parts generally includes the process route of parts processing, the specific content of each process, the equipment and process equipment used, the inspection items and inspection methods of the parts, the rated time and cutting volume, etc.
There are many advantages of precision parts machining, which can effectively improve production and efficiency, have considerable feed benefits and reduce business costs. Precision manufacturing and processing technology can also improve labor conditions, shorten working time, reduce labor intensity and improve civilized production. In addition, precision machining can reduce more personnel and site rent, shorten the production cycle, reduce costs and save energy. Therefore, the application of precision machining technology has many benefits.
Precision machining of mechanical parts uses automatic detection and monitoring devices, which helps to improve the output and stability of products, and flexible automated production can quickly adapt to product changes. Therefore, the impact of precision machining technology on industrial production is actually very great, but the initial investment in precision machining parts processing technology will be relatively high. Therefore, users need to be careful when choosing a precision machining manufacturer. A good machinist can bring better quality and efficient product processing and can reduce the overall cost.
Surface roughness of mechanical parts machining is an important technical index reflecting the micro geometric error of mechanical parts machining surface, is the main basis for testing the quality of the surface layer of the parts, directly related to the quality of goods, service life, product cost. The methods of selecting the surface roughness of mechanical parts are calculation methods, testing methods and analogous ways.
A common application in the machining design of mechanical parts is the analogical approach, which is simple, fast and reasonable; the application of this requires sufficient reference material, and a large amount of material and reference material is currently given in various mechanical structure design guides. Commonly, surface finish is compatible with dimensional tolerance levels. Generally speaking, the smaller the standard tolerance for machining and production of mechanical parts, the smaller the surface roughness value of mechanical parts, but there is no fixed functional relationship between them.
Mechanical parts machining strength is the ability of the part not to break or undergo more than the allowed plastic deformation during work, and is the basic provision for all normal operation and production safety of the equipment. Standard countermeasures to improve the strength of the part are: in order to expand the specifications of the risky cross-section of the part, expand the moment of inertia of the cross-section, effective design of the cross-section of the case; the use of high-strength raw materials, the raw materials to expand the heat treatment process to improve the strength and reduce thermal stress, operation of the manufacturing process to reduce or eliminate microscopic shortcomings, etc.; in order to reduce the load of the parts to reduce the stress level, etc., the structure of the parts should be properly involved.
