High-speed reaming of low carbon steel multi-layer tube plate holes
Mild steel (20 or A3) is a material with low hardness (strength) and high viscosity. Therefore, its cutting performance is poor. In order to make the roughness of the machined hole reach Rα6.3 after finishing, at present, high-speed steel cutters are generally used in China, and low-speed cutting is used. The drilling, expansion and hinge processes are used to complete the hole processing. Meet the requirements of machining accuracy and roughness, but with low production efficiency and short tool life. Especially when the processed hole is a multi-layer tube sheet, due to the flatness of the surface of the tube sheet,
