Shovel Blades for Construction Machinery

Shovel blades for construction machinery should be precisely cut from high-quality wear-resistant steel. Laser cutting or plasma cutting is typically used to obtain blanks close to the final shape. Key areas (such as the cutting edge) require heat treatment, primarily quenching and tempering, to significantly increase surface hardness by precisely controlling heating and cooling, while maintaining the toughness of the base material to prevent fracture.

Deformation caused by heat treatment must be corrected through a leveling process, usually using large presses or roller levelers, to ensure the flatness of the plate meets stringent standards. This is followed by the finishing stage, where the core process is milling with large CNC milling machines. This is used to precisely machine mounting surfaces, bolt hole positions, and various slots, ensuring proper fit and assembly accuracy when connecting to the main machine. All connection holes must be drilled and tapped to ensure accurate positioning and thread strength.

Finally, surface treatments such as shot peening may be performed to relieve stress, clean the surface, and prepare it for coating. The entire machining process is closely focused on improving the products service life and operational reliability, with each process directly related to the final performance of the shovel blade.
