The manufacturing of rotary tiller blades involves precision forging and heat treatment processes. First, forging shapes the steel into a specific form, enhancing the density of its internal structure. Then, quenching and tempering processes form a high-hardness martensitic layer on the blade surface while maintaining internal toughness to prevent breakage during high-speed rotation. Some high-end blades also utilize laser cladding technology to coat the surface with wear-resistant materials, further extending their service life.
