Process characteristics and knowledge of precision machining
Precision mechanical processing is a kind of mechanical processing, which is a processing technology where the workpiece meets the line tolerance required by the drawing. During this process, the workpiece will have certain changes in its performance characteristics and shape structure.
Mechanical parts design, as a discipline of mechanical majors, is one of the most popular majors for science students and one of the strongest engineering majors.At present, this major requires not only good engineering knowledge, but also excellent drawing ability and spatial imagination ability. Moreover, due to the development of domestic industry and the constant change of demand, the demand for personnel in the mechanical processing industry is also increasing, and the employment rate of the mechanical major can reach 95%.
With the development and progress of domestic industry, machining has changed a lot and precision machining technology has come to the fore. Many industries such as household appliances, automobiles, hardware and medical manufacturing use more or less precision parts.It could be just a component or it could be a core component of a mechanical device.In a word, it is very important and plays an irreplaceable role.
These precision parts for precision machining manufacturing has two processes, one is hot processing and one is cold processing, hot processing is through heat treatment and other ways to make the parts in very warm conditions under the biochemical or physical changes to meet the requirements of shape change.And cold machining is at room temperature does not produce chemical and physical changes to meet the requirements of shape change, generally using cutting technology.In the future, on the premise of satisfying processing and environmental protection, precision machining will be combined with science and technology and become an important and sustainable science.
Do you really know what the non-standard parts of precision machining are？
Non-standard parts, I believe, are the most exposed and in demand in the machinery manufacturing industry. Most of the parts in automation equipment, or the jigs used in processing and inspection, are the specifications and parameters of which are freely controlled by enterprises.Therefore, such enterprises will submit the drawings of required parts to the corresponding precision machining manufacturers for processing to meet the shape and position tolerances required by the drawings.
From the words above, we may draw a fuzzy concept, non-standard parts is relative to the standard parts, it will not have standardized as standard parts of structure, size, tag, and drawing, etc., non-standard parts mainly countries do not have set strict standard, regulation, no related parameters controlled by the enterprise according to their own production needs of accessories, therefore, to a certain extent, manufacturing cost is higher than the standard parts.
At present, there is no very standard classification of non-standard parts, which can be divided into metal non-standard parts and non-metal non-standard parts roughly according to the material. Metal parts are the raw materials of metal, such as brass, aluminum, etc. Tolerance requirements and finish degree are regulated by the customer, and the process is complicated. Non-metal parts are the raw materials of plastic, wood and stone, etc
