CNC machining carbon steel parts involves using computer-controlled machines to remove material from a carbon steel workpiece to create the desired shape and size. Carbon steel is a popular material choice because of its strength, durability, and workability.

Steel CNC milling refers to the process of using CNC (Computer Numerical Control) milling machines to precisely cut and shape steel workpieces. This process involves the use of computer-controlled rotating cutting tools to remove material from steel workpieces to achieve desired shapes, dimensions, and surface finishes. 

(1) Blanks of shaft parts Shaft parts can be made in the form of blanks such as bars, forgings, etc. according to the usage requirements, production type, equipment conditions and structure. For shafts with a small difference in outer diameter, bar stock is generally used; for stepped shafts or important shafts with a large difference in outer diameter, forgings are often used, which not only saves materials but also reduces the workload of machining. Improve mechanical properties.

(2) Materials for shaft parts Shaft parts should be made of different materials according to different working conditions and usage requirements and adopt different heat treatment specifications (such as conditioning, normalizing, quenching, etc.) to obtain certain strength, toughness and Wear resistance.
