Precision machining is a type of machining process that achieves the dimensional tolerances required by the drawings. During this process, the workpiece undergoes certain changes in its performance characteristics and structural shape.

With machining, there are naturally corresponding parts. Mechanical parts design, as a discipline in mechanical engineering, is one of the popular majors chosen by science students and is also one of the strongest engineering fields. Currently, this major not only requires good knowledge of science and engineering but also excellent drawing skills and spatial imagination. Moreover, due to the development of domestic industry and the constantly changing demand, the demand for personnel in the machining industry is also increasing, with an employment rate for mechanical majors reaching 95%.

With the development and progress of domestic industry, machining has changed a lot, and precision machining technology has emerged. Many industries, such as home appliances, automobiles, hardware, and medical manufacturing, use products that incorporate precision parts to varying degrees. It could be just a component or a core part of a mechanical device. In short, it is very important and plays an irreplaceable role.

The manufacturing of these precision parts through precision machining involves two processes: hot processing and cold processing. Hot processing involves chemical or physical changes to the parts under very warm conditions to meet the shape change requirements through methods like heat treatment. Cold processing, on the other hand, does not involve chemical or physical changes at room temperature to meet the shape change requirements, generally using cutting technology. In the future, under the premise of meeting processing and environmental protection requirements, precision machining will combine with technology to become an important and sustainable science.

Do you really understand what non-standard parts in precision machining are?

Non-standard parts, I believe, are the most encountered and demanded in the mechanical manufacturing industry. Many parts in automated equipment or fixtures used for processing and inspection are mostly specifications controlled freely by enterprises. Therefore, these enterprises will hand over the drawings of the required parts to corresponding precision machining manufacturers for processing to meet the shape and position tolerances required by the drawings.

From the above text, we can derive a vague concept: non-standard parts are proposed in relation to standard parts. They do not have the standardized structure, size, markings, and drawing methods that standard parts possess. Non-standard parts mainly arise because the country has not established strict standard specifications, and there are no relevant parameter regulations, allowing enterprises to freely control the components according to their production needs. Therefore, to some extent, the processing cost is higher than that of standard parts.

Currently, non-standard parts do not have very standardized classifications. They are roughly divided into metal non-standard parts and non-metal non-standard parts based on material. Metal parts are those whose raw materials are metal, such as brass and aluminum, with tolerance requirements and surface finish specified by the customer, and the processes are complex. Non-metal parts are those whose raw materials are plastic, wood, stone, etc.

Wuxi Fuwangde Technology Co., Ltd. was established in 2016 with a registered capital of 5 million yuan. It is located in the Satellite Industrial Park in the Xinwu District of Wuxi, covering an area of 2,000 square meters. Currently, there are more than twenty CNC lathes and machining centers. The company is equipped with complete testing equipment and has a high-level professional team familiar with domestic and international mechanical industry norms and standards, and it also has rich supporting resources needed by various processing industries nearby.
