Cutting tool selection:
Carbide Tool: Carbide tool is usually the first choice for machining stainless steel because it has excellent hardness, wear resistance and heat resistance, and is suitable for high-speed cutting and long-term machining.
Indexable Carbide Inserts: These tools have replaceable cutting inserts, which can effectively control processing costs and improve production efficiency.
High-Speed Steel Tool: In lighter applications, high-speed steel tools can also be used to process stainless steel, but their wear resistance and heat resistance are worse than carbide tools, so the tool life is longer. short.
Diamond Tool: When used for super-hard stainless steel or high-precision machining, diamond tools have excellent wear resistance and cutting ability.
Material properties:
Hardness: Stainless steels generally have high hardness, so the tool material needs to be hard enough to resist cutting stress and wear.
Wear resistance: The wear resistance of stainless steel makes tools prone to wear, so tool materials need to have excellent wear resistance to extend tool life.
Heat resistance: In stainless steel processing, the tool may become soft or deformed due to high temperature, so the tool material needs to have good heat resistance to ensure processing efficiency and tool life.
Corrosion resistance: Corrosive media may be generated during stainless steel processing, so the tool material needs to have a certain degree of corrosion resistance to prevent corrosion and deterioration of the tool surface.
Tool coating:
Titanium Nitride (TiN): One of the commonly used tool coatings, it provides good wear resistance and heat resistance, reduces cutting forces and extends tool life.
Chrome Plating: Used to improve the wear resistance and corrosion resistance of tools, and is suitable for some application scenarios of stainless steel processing.
Aluminum Oxide (Al2O3): Provides excellent heat resistance and chemical stability, suitable for high temperature and high speed processing.
