The precision machining industry has always been a labor-intensive, capital-intensive, and technology-intensive industry. The industry has a high threshold. Even if a general enterprise does not reach a certain scale, it will be difficult to generate profits. Large enterprises can reduce costs through large-scale procurement and production, business coordination, and build a regional sales market that covers products from different regions and industries. Therefore, the precision machining industry has a relatively strong Hengqiang characteristic. In the future, this industry will mainly focus on integration, regional integration, industrial chain integration and strategic integration.
Among them, regional integration is the combination of precision processing enterprises in the same region, so it can focus on the application of policy and management advantages, and produce a good synergy and cooperation effect. Industrial chain integration is a single function united by the machining industry, or downstream manufacturing companies can work with key component suppliers to solve technical bottlenecks facing complex components; strategic integration is the introduction of strategic partners such as automobiles and military to Grasp downstream needs more accurately, develop targeted products, and reduce unnecessary losses during research and development.
The procedures of precision parts processing have extremely strict requirements. A little carelessness during processing will cause the workpiece error to exceed the tolerance range, and it will be necessary to reprocess or announce the scrap of the blank, which greatly increases the production cost. Therefore, today we talk about the requirements of precision parts processing, which can help us improve production efficiency. The first is the size requirements. Be sure to strictly follow the form and position tolerance requirements of the drawing for processing. Although the components processed and produced by the enterprise will not be exactly the same as the dimensions of the drawing, the actual dimensions are within the tolerance range of the theoretical dimensions, which are all qualified products and can be used parts.
Secondly, in terms of equipment, roughing and finishing should be performed using equipment with different performance. Because the roughing process cuts most parts of the blank, the workpiece will generate a large amount of internal stress when the feed is large and the cutting depth is large. At this time, finishing cannot be performed. When the workpiece is finished in a certain period of time, it should work on a higher-precision machine so that the workpiece can achieve high accuracy.
The processing of precision parts often involves surface treatment and heat treatment. The surface treatment should be placed after precision machining. And in the precision machining process, the thickness of the thin layer after surface treatment should be considered. Heat treatment is to improve the cutting performance of the metal, so it needs to be performed before machining. The above are the requirements to be followed in the processing of precision parts.
