>> Product Raw Material

• Alloy Steel: High-quality alloy steel is often the main base material. Elements like chromium (Cr), nickel (Ni), molybdenum (Mo), and manganese (Mn) are alloyed into the steel. For example, 40Cr steel is commonly used. Chromium can improve the hardness, strength, and corrosion resistance of the material. Nickel enhances toughness and heat resistance. Molybdenum can improve the hardenability and strength at high temperatures, and manganese can increase the strength and hardenability.

Raw Material Preparation

• Inspection and Testing: The alloy steel or bronze alloy materials are inspected for their chemical composition, mechanical properties, and surface quality to ensure they meet the required standards.

• Cutting to Size: The raw materials are cut into appropriate sizes and shapes according to the design requirements of the bushing using sawing machines or cutting torches.

Forming

• Forging: For alloy steel materials, forging is often used to improve the internal structure of the material, refine the grains, and enhance the mechanical properties. The pre-cut materials are heated to a suitable temperature and then forged into the approximate shape of the bushing using forging hammers or presses.

• Casting: In the case of bronze alloys, casting is a common method. The molten bronze alloy is poured into pre-made molds to form the bushing. Precision casting techniques such as investment casting can be used to achieve high-precision shapes.

Machining

• Turning: The semi-finished bushings are clamped on lathes to machine the outer and inner diameters, end faces, and other surfaces to achieve the required dimensional accuracy and surface roughness.

• Drilling and Reaming: Holes for installation and lubrication are drilled and then reamed to ensure the accuracy of the hole diameter and the straightness of the hole axis.

• Grinding: Grinding is carried out on the inner and outer surfaces of the bushing to further improve the dimensional accuracy and surface finish, meeting the high-precision requirements of the excavator arm bushing.

Heat Treatment

• Quenching and Tempering: For alloy steel bushings, quenching and tempering treatments are usually performed. Quenching can improve the hardness and strength of the material, and tempering is used to eliminate internal stresses, improve toughness, and stabilize the microstructure to enhance the overall performance of the bushing.

• Annealing: For some bronze alloy bushings, annealing may be carried out to relieve internal stresses and improve the plasticity and machinability of the material.

Surface Treatment

• Lubricating Film Coating: A lubricating film such as molybdenum disulfide or graphite coating is applied to the surface of the bushing to reduce friction and improve wear resistance.

• Anti-corrosion Treatment: The bushing may undergo processes such as electroplating, chemical plating, or painting to form an anti-corrosion layer on the surface, protecting it from rust and corrosion in harsh working environments.
