Material selection for CNC machining

In the field of material selection, we have built a comprehensive and high-quality material library to meet the diverse needs of different industries and application scenarios. In terms of metal materials, carbon steel covers various types such as Q235 and 45 #, which are suitable for mechanical structural components with basic requirements for strength and toughness; Stainless steel, including 304 and 316L, is commonly used in the manufacturing of components such as food processing equipment and medical devices due to its excellent corrosion resistance; Aluminum alloy models such as 6061 and 7075, with their light weight and high strength, have become ideal choices for lightweight automotive components and drone frames; Titanium alloy is widely used in high-end products such as aircraft engine blades and orthopedic implants due to its high strength, high temperature resistance, and good biocompatibility. After each batch of materials enters the factory, we conduct multiple tests such as spectral analysis and tensile testing to ensure that the material properties fully meet international standards and customer requirements, laying a solid foundation for product quality from the source.

The production process of CNC Machining

We have established a refined and fully controlled production system to ensure that every product can be produced with high quality. In the product design and programming stage, our engineering team uses professional CAD/CAM software such as SolidWorks and UG, which can not only accurately reproduce customer design intentions, but also predict potential problems in advance through simulation machining and optimize machining solutions. Entering the processing stage, the real-time monitoring system equipped on the CNC machine tool can monitor key parameters such as cutting force and spindle temperature in milliseconds. Once abnormalities are detected, the processing parameters will be automatically adjusted to ensure stable processing. Taking the processing of a complex mold as an example, from blank to finished product, there are 7 processes including rough machining, semi precision machining, and precision machining. After each process is completed, online measurement is carried out, and processing errors are corrected in a timely manner using data feedback. Finally, after polishing, deburring, and other fine polishing, the surface roughness of the mold reaches Ra0.8, meeting the dual requirements of customers for mold accuracy and surface quality.

Surface treatment of CNC machining

Surface treatment is a key process that endows our products with outstanding performance and exquisite appearance. For aluminum alloy materials, anodizing treatment can form a dense oxide film on its surface, improving the corrosion resistance of the product by 3-5 times. At the same time, various color effects can be achieved through dyeing processes, which are widely used in electronic product casings; For steel parts, electroplating technology can not only enhance their wear resistance and rust prevention ability, but also give the parts different appearances such as chrome plated mirror luster and galvanized metallic texture; The spray painting process adopts electrostatic spraying technology, with uniform coating thickness and strong adhesion, which can effectively resist acid and alkali corrosion and ultraviolet aging. It is commonly used for outdoor mechanical equipment casings; Sandblasting treatment uses the impact of high-speed sand flow to form a uniform rough texture on the surface of the parts, increasing surface friction and suitable for assembly components that require improved bonding strength. We flexibly choose or combine multiple surface treatment processes based on the product’s usage environment and customer needs, making the product both practical and visually appealing.

Dimensional Inspection in CNC Machining

In the dimension inspection process, we have established a professional quality inspection team, equipped with world-class testing equipment, and implemented strict quality control standards. The coordinate measuring instrument can measure products in three-dimensional space in all directions, with a measurement accuracy of up to 0.001mm. Whether it is complex spatial surfaces or small aperture sizes, it can accurately capture them; The image measuring instrument uses a high-definition imaging system to quickly measure the two-dimensional contour of parts, with measurement efficiency more than 10 times higher than traditional calipers. We implement the ISO 9001 quality management system standard and conduct sampling testing on each batch of products, with a testing ratio of no less than 10%. For key components, we also implement full inspection. In a transmission gear inspection for the rail transit industry, it was found through a coordinate measuring instrument that the tooth profile error exceeded the standard by 0.003mm. The quality inspection team immediately initiated a traceability program, adjusted the processing parameters, and reprocessed the product, ultimately ensuring that the product was 100% qualified before leaving the factory and winning customer trust with zero defect quality.

Application of CNC Machining Products

Our CNC machining products play an important role in many industries due to their excellent quality and high-precision performance. In the automotive manufacturing industry, the steering knuckles we produce are optimized in processing technology and material selection, resulting in a 15% reduction in part weight and a 20% increase in strength, effectively contributing to the lightweighting and safety improvement of automobiles; In terms of medical equipment, the orthopedic implant screws we process are made of medical titanium alloy material, which has undergone high-precision surface treatment to achieve a surface roughness of Ra0.2, greatly reducing the rejection reaction with human tissue; In the field of electronic devices, the heat sinks we manufacture for 5G base stations have achieved the processing of 0.3mm ultra-thin fins through precision milling technology, greatly improving heat dissipation efficiency. From high-end equipment manufacturing to consumer goods, our products always provide reliable quality to safeguard the development of various industries.
