How to product precision CNC Machining parts

April 13, 2022

Once we need customized some goods ,but do you know what the schedule we need follow?

1. First of all, after receiving the customer's drawings, our engineers should carefully check the material requirements and processing requirements of the product. Distinguish whether this product is profile processing or blank processing, and blanks are divided into castings and forgings. After determining the machining blank, before starting the precision machining, it is necessary to select a suitable CNC machine tool and write several sets of economical and efficient plans for the machining process. Surfaces with high machining quality requirements are divided into processing stages, which can generally be divided into three stages: roughing, semi-finishing and finishing, which may involve broaching, wire cutting, welding, drilling, tapping, and heat treatment. And surface treatment and other processes, mainly to ensure the processing quality and meet the use requirements of the work piece.

2. Then formulate an appropriate CNC/machining machining plan for precision parts, analyze the drawings of the parts to be machined, process the parts and use appropriate machining techniques.

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 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 you must pay attention to the density of the material before processing. For some materials that do not meet the hardness requirements, relevant heat treatment methods are used to process them.

4. Next, in the processing of high-precision parts, it is important to write and design the process flow, because 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
