As a critical operational component, the quality of the cutter head directly impacts the operational efficiency and service life of the entire equipment. This cutter head is crafted using precision casting technology. Through an advanced casting process, molten metal fully fills the mold and cools uniformly—this not only precisely replicates the cutter head’s complex structure and dimensional accuracy but also ensures a dense internal texture, effectively minimizing defects like pores and sand holes, thus laying a robust foundation for its high-strength performance.​

In terms of material selection, the cutter head is constructed from 40CrMo alloy structural steel. Boasting exceptional comprehensive mechanical properties, this material offers high hardness, superior toughness, and remarkable wear resistance and fatigue resistance. Even under high-intensity, high-frequency operational conditions, it maintains stable cutting performance, significantly prolonging the cutter head’s service life.​

To guarantee that every unit meets stringent standards, all cutter heads undergo 100% inspection and straightening prior to leaving the factory. The full inspection process encompasses multiple criteria, including dimensional precision, surface finish, and mechanical properties, thereby eliminating substandard products from entering the market. Meanwhile, the professional straightening process accurately rectifies any potential minor deformations, ensuring the cutter head’s straightness and installation precision. This ensures a seamless fit with the equipment post-assembly and enhances operational stability.​

Whether through the structural reliability delivered by precision casting technology, the durability imparted by 40CrMo material, or the precision ensured by the full inspection and straightening process, this cutter head fully satisfies the core demands of industrial operations—efficiency, durability, and stability.
