CNC Machining for Shaft

Shafts, sleeves and disc parts are typical parts with outer surfaces. The commonly used mechanical processing methods for the outer surface include turning, grinding and various finishing methods. Turning processing is the most economical and effective processing method for the outer surface, but in terms of its economic accuracy, it is generally suitable for the rough and semi-finishing processing methods of the outer surface; due to the economic processing accuracy and surface that can be achieved by various processing methods Roughness, productivity, and production costs are different, so a reasonable processing method must be selected according to the specific situation, so as to process qualified parts that meet the requirements on the part drawings..

Cnc Machining Material For Shaft

The selection of shaft parts materials is mainly determined according to the strength, rigidity, wear resistance and manufacturing process of the shaft, and strives to be economical and reasonable. Commonly used materials for shaft parts are 35, 45, and 50 high-quality carbon steel, with 45 steel being the most widely used.

Ordinary carbon steels such as Q235 and Q255 can also be used for shafts with small or less important loads. Alloy steel can be used for larger forces, limited axial size and weight, or some special requirements. For example, 40Cr alloy steel can be used for medium-precision, high-speed work occasions, the material has better comprehensive mechanical properties after quenching and tempering treatment; the use of Cr15, 65Mn and other alloy steels can be used for high-precision and poor working conditions , These materials have good wear resistance and fatigue strength after quenching and tempering and surface quenching;

For shaft parts that work under high-speed and heavy-load conditions, use low-carbon steel such as 20Cr, 20CrMnTi, 20Mn2B, or 38CrMoA1A carburized steel. After carburizing and quenching or nitriding, these steels not only have high surface hardness, And the strength of its core is also greatly improved, so it has good wear resistance, impact toughness and fatigue resistance. Nodular cast iron and high-strength cast iron are often used in the manufacture of shafts with complex shapes and structures due to their good casting properties and vibration damping properties. In particular, the rare earth magnesium spheroidal graphite cast iron developed in my country has good impact resistance and toughness. It also has the advantages of friction reduction, vibration absorption, and low sensitivity to stress concentration. It has been used in the manufacture of important shaft parts for automobiles, tractors, and machine tools. .
