Lockable End Cap Cnc-Milled Part

The CNC Milling part is a closure cover made of aluminum alloy AL6061, characterized by a square shape with a simple and compact exterior for easy installation and positioning. It is equipped with a standard internal screw G2 in the middle for reliable connection to pipelines or other components. The symmetrically distributed mounting openings are arranged at the four angles, which allows secure fastening with bolts, to avoid dismantling or deformation during operation. All edges are cut to improve safety and reduce stress concentration. The end cover adopts a solid structure with uniform and reasonable wall thickness, which guarantees global stiffness and durability, It meets the requirements of ease.

Step 1: First, we cut the material of AL6061 aluminum alloy rod and reserve an appropriate treatment concession depending on the product dimensions and lay the Basics for the following processes; It then proceeds to the thickening phase, in which most of the excess material is quickly removed with the help of CNC milling machine. The thick product contour, the large central opening and the assembly opening of the preformed flange are milled, wherein the shape and position errors are controlled after thick machining in order to reduce the cutting stresses and deformation risks for precision machining.

Step 2: After finishing the thick machining, carry out the aging treatment, to release the internal tension during machining and then enter the precision machining phase. Use the high-precision CNC milling to achieve ultra-precise machining on the flange end side, carry out the mounting opening and the central thread drilling: the flange closure side is formed at once to ensure the flatness and roughness; The rectangular mounting holes undergo a process of drilling and discs to ensure that the position error of the position of the hole is controlled at a very small distance; The central threaded bore G2 is formed at once with the help of a special threaded milling machine, which precisely controls the throughput, profile angle and throughput size, to ensure the interchangeability and sealing of the threaded connection.

Step 3: After completion, perform the treatment of outbreaks, to remove all bags and pouches on the machined edges and avoid injections and assembly disturbances; Then insert the process of surface treatment, first form a uniform and sensitive opaque surface by treating the sandblast, remove the treatment marks and improve surface adhesion; Finally, a hard anodizing treatment is carried out to form a dense oxide film on the surface of the aluminum alloy, thereby increasing the wear resistance, the corrosion resistance and insulation of the product are greatly improved, so that the end cap is also under complex working conditions such as humidity, oil stains, high and low temperatures can maintain stable performance over a long period of time.

As a professional manufacturer of precision components, Dongguan Shengpeng Precision Technology Co., Ltd. through a mature precision machining system and can provide complete CNC milling services that are customized, to meet the individual needs of customers. We can provide the dimensional specifications, flange configuration and screw standards adjust the locking cap depending on the working conditions of the customer's equipment and the connection requirements. At the same time, we support the replacement of materials (adapted to different metal materials that meet industrial standards) and the regulation of the surface treatment process (such as sanding with different mesh sizes, anodizing with different colors, hard oxidation, etc.), fully meet the customer's product design needs.
