What about high-precision parts?

What is cnc machining of precision parts, no matter in terms of material or craftsmanship, they are all made with very careful craftsmanship. It is not a mass-produced part, but a mechanical process. For precision parts, very strict. The precision of parts is also one of the foundations of enterprise competitiveness. The workpiece processing requirements in precision machining generally use CNC for precision machining of parts.

When performing precision cnc machining, the machinery processing plant must not only meet the customer's workpiece processing technical requirements, but also have the required performance. At the same time, it must pay attention to improving production efficiency and worker efficiency, so as to provide customers with more economical and long-term effective Serve. The following editor will explain to you what the general processing operation process of high-precision parts processing manufacturers is like!

1) After receiving the customer's drawing processing requirements, before starting precision cnc processing, it is necessary to select a suitable CNC machine tool and write several sets of processing programs. The appearance that requires high machining quality is divided into processing stages, which can generally be divided into three stages: rough processing, semi-finishing and finishing. It is mainly to ensure the processing quality; it is beneficial to the scientific application of equipment, it is convenient to arrange the heat treatment process, and it is easy to find blank defects.

2) Then formulate a suitable CNC machining plan for precision parts, analyze the drawings of the parts to be processed, carry out CNC processing of parts for the processing content of the parts, and adopt an appropriate processing technology.

3) Selection of material hardness. In some occasions, the higher the hardness of the material, the better, but only limited to the hardness requirements of the processed parts. The material is moderately soft and hard, at least one grade lower than the hardness of mechanical parts. Therefore, the most basic point is to pay attention to the density of the material before processing.

4) Next, in the processing of high-precision parts, it is very important to write and design the process flow. Due to the program steps of part processing, the selection of benchmarks, the selection of processing tools, the selection and installation of fixtures, and the determination of processing strategies and process parameters. affect product quality.

5) Finally, in the process of processing high-precision parts, it is also necessary to pay attention to the full inspection of product quality before arranging shipment. If it does not meet the requirements of the drawing, the secondary processing meets the requirements of the drawing size, precision, tolerance, technical parameters, etc.
