Versatile Transmission Spindle for Multi-Scenario Industrial Machinery

Forging transforms solid metal from one shape to another through plastic forming processes like extrusion or punching. Casting transforms liquid metal into a solid shape by pouring molten metal into a mold. Forging is a solid-to-solid process, while casting is a solid-liquid-solid process.

Quality is determined by external observation (checking dimensions, surface defects like cracks or bubbles) and internal testing (analyzing chemical composition, microstructure, and mechanical properties like tensile strength and hardness using specialized instruments).

The process includes pier roughening, elongation, punching, and expanding. Free forging uses a horse screw to expand holes, while ring rolling uses rolling. Both methods aim to achieve the desired shape and internal structure.

The spindle is made from 45# carbon structural steel (GB standard), which has 0.45% carbon content. It offers low price, good cutting performance, and high hardness after quenching and tempering.

The product is certified under GB/T19001-2016 and ISO9001:2015 standards, ensuring quality management and product reliability.
