What is precision parts processing? Precision parts are small and delicate. No matter in terms of material and craftsmanship, they are produced through a wealth of experience and careful arrangement of craftsmanship. They are by no means batch-produced parts, but also a type of machining. For precision parts, the machining is very strict. Disapprovingly, the precision of the parts is also one of the foundations for the development of the competitiveness of the enterprise.
The workpieces in the precision machining process generally require CNC machine tools for precision machining of the parts, and they are processed through multiple processes. , The machining error and positioning error are controlled within the effective tolerance range to meet the technical requirements of the workpiece to be qualified products.
When the machining factory performs precision machining, it not only meets the customer's workpiece processing technical requirements, but also has the required performance and should pay attention to the improvement of production efficiency and worker work efficiency, so as to provide customers with more economical and long-term effective services. . Then let Shenzhen Xinsheng Precision Hardware Machinery Co., Ltd. explain to you the general processing operation process of high-precision parts processing manufacturers!
First of all, after receiving the customer's drawing processing requirements, before starting precision machining, it is necessary to select a suitable CNC machine tool and write several sets of economical and efficient solutions for processing procedures. Surfaces with high machining quality requirements are divided into processing stages, which can generally be divided into three stages: rough machining, semi-finishing and finishing. It is mainly to ensure the quality of processing; it is conducive to scientific application of equipment; it is convenient to arrange heat treatment procedures; and it is convenient to find blank defects, etc. Then formulate an appropriate machining plan for CNC/machining of precision parts, analyze the drawings of the parts to be machined, process the parts for the machining content and use appropriate machining techniques.
Secondly, the choice of material hardness. For some occasions, the higher the hardness of the material, the better, but it is limited to the hardness requirements of the processing machine parts. The material is moderately soft and hard, at least one grade lower than the hardness of the machine parts. The basic one is that before processing, we must pay attention to the density of the material and the processing method of the type of machine tool.
Next, in the processing of high-precision parts, it is important to write and design the process flow. Because of the program steps of part processing, the selection of benchmarks, the selection of processing tools, the selection and installation of fixtures, and the processing strategies and process parameters are determined. affect the quality of the product.
Finally, in the process of high-precision parts processing, we must also pay attention to the full inspection of product quality, and then arrange shipment. If it does not conform to the drawings, secondary processing will be performed to meet the requirements of the drawings, such as size, accuracy, tolerance, and technical parameters. Shenzhen Xinsheng Precision Hardware Machinery Co., Ltd. is equipped with a complete range of precision machining equipment, CNC machine tools, testing equipment, and has more than ten years of experience in exporting precision machining.
