CNC machining: How are high-precision CNC machining parts processed?

What is precision parts machining? Small and delicate, both in terms of material and craftsmanship, they are all made with careful craftsmanship. They are by no means batch-produced CNC machining parts, but also a type of machining. For precision CNC machined parts, the machining is very strict. Disapprovingly, the precision of the parts is also one of the foundations that represent the competitiveness of the company's development. The workpiece processing requirements in precision machining generally use the form of CNC for precision machining of parts.

When machining parts with precision CNC machining, the machining factory not only meets the technical requirements of the customer's workpiece processing, but also has the required performance and should pay attention to the improvement of production efficiency and worker's work efficiency, so as to bring more economical and long-term effects to customers. CNC machining services. Then let VMT explain to you the general processing operation process of high-precision CNC machining parts manufacturers in China!

1) First of all, after receiving the customer's drawing machining requirements, before starting the precision CNC machining, it is necessary to select a suitable CNC machining machine and write several sets of CNC machining procedures that are economical and efficient. Surfaces with high machining quality requirements are divided into CNC machining stages, which can generally be divided into three stages: rough machining, semi-finishing and finishing. It is mainly to ensure the quality of CNC machining; it is conducive to scientific application of equipment; it is convenient to arrange heat treatment processes; and it is convenient to find blank defects.

2) Then formulate an appropriate precision CNC machining part plan, conduct dfm analysis on the drawings of the parts to be machined, discuss and adopt appropriate CNC machining technology.
 

3) 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 CNC machined parts. The basic one is that you must pay attention to the density of the material before CNC machining.

4) Next, in high-precision machining parts, it is important to write and design the process flow. Because of the program steps of part machining, the selection of benchmarks, the selection of machining tools, the selection and installation of fixtures, and the processing strategy and process parameters are determined. affect the quality of the product.

5) Finally, in the process of high-precision machining parts, we should also pay attention to the full inspection of product quality, and then arrange shipment. If it does not conform to the drawing, it will be processed twice to meet the requirements of the size, accuracy, tolerance, and technical parameters of the drawing. VMT is equipped with a complete range of precision CNC machining equipment, CNC machine tools, and testing equipment. With more than ten years of experience in precision CNC machining services, and strict control of product quality, it can provide a one-stop service that saves worry and effort.
