In modern manufacturing, steel, as an important raw material, is widely used in the processing and manufacturing of machined precision parts customization. However, how to improve the strength of parts through steel machining technology has always been the focus of attention in the manufacturing industry.
First of all, heat treatment is an effective means to improve the strength of steel parts. Heat treatment includes several different processes such as annealing, normalizing, quenching and tempering, which manipulate the temperature of steel to change its material properties. For example, annealing can reduce the hardness and increase the ductility of steel, making it easier to process; while quenching will make the steel harder and increase the strength, but may make it brittle. Tempering is used to reduce the brittleness after quenching and increase toughness. Through a reasonable heat treatment process, the microstructure of steel can be optimized, thereby improving the overall strength of the parts.
Secondly, precipitation hardening technology is also an important method to improve the strength of steel parts. Precipitation hardening steel contains elements such as copper, aluminum, phosphorus and titanium, which form solid particles in the steel and increase the strength of the material. To activate the precipitation hardening properties, the steel is first solution treated and then age hardened, which means that the material is heated for a longer period of time to produce precipitation. This process can change the properties of the steel without adding too much heat, significantly improving the yield strength of the part.
In addition, cold working is also an effective way to improve the strength of steel parts. During cold working, steel will produce work hardening when it is plastically deformed, and it can be made stronger by intentionally hammering, rolling or pulling the metal. Cold working can also improve the machinability of steel and improve the surface quality and dimensional accuracy of parts. At the same time, the residual stress generated during cold working will also increase the strength of parts to a certain extent.
In the process of steel machining, choosing the right cutting parameters and tools is also the key to improving the strength of parts. Reasonable cutting parameters can optimize the grain structure of the part surface and enhance its hardness and strength. And high-quality tools can reduce friction and heat during cutting, reduce thermal deformation and surface damage of parts, thereby improving their strength and durability.
Through heat treatment, precipitation hardening, cold working, and reasonable cutting parameters and tool selection, the strength of machined precision parts customization can be significantly improved during steel machining. These processes not only optimize the microstructure of steel, but also improve the surface quality and dimensional accuracy of parts, providing strong support for the development of modern manufacturing industry.
