This is a component machined by CNC milling. Since this product is in the R&D stage, it is necessary to get a sample quickly to test all aspects of the whole set of products; and since it is a newly developed product, it is inevitable to improve or upgrade the parts during the testing process. Therefore, this type of product is most suitable for CNC machining. CNC machining parts have high precision, high efficiency and high flexibility. The machining program can be adjusted at any time according to the needs of product changes to machine the latest products. Therefore, CNC precision machining is very suitable for the R&D stage or small and medium-sized batch production.
