1. Material: 42CrMo alloy
2. Manufacturing process: blanking, rough turning, quenching and tempering heat treatment, finish machining, dynamic balancing correction,
3. Dimensional Characteristics: The assembly consists of a large-diameter, rotating disc component with a multi‑step stepped structure on its face. The upper workpiece has closely spaced through-holes of varying sizes around its circumference; on the lower side, mounting seats are uniformly distributed along the outer periphery. Both types of parts demand extremely tight coaxiality between their central holes. Overall end‑runout and coaxiality are rigorously controlled, ensuring minimal eccentricity at high speeds and smooth operation.
4. Surface Treatment: Blackening for rust prevention
5. Product Applications: This is a large, precision rotary disc component, commonly used as brake discs in construction machinery, bases for fan impellers, and mounting bases for automated turntables. The disc’s through-holes and locating seats accommodate bolt‑fastened mating components, while the central hole and drive shaft interface to transmit torque. It finds extensive application in mining equipment, large fans, and heavy‑duty non‑standard transmission systems.
