Choose the right CNC power milling machine tool material according to the hardness of the material

Choosing the right tool material is one of the key factors to ensure the processing performance of CNC power milling machines, and the hardness of the material is an important basis for tool material selection. The differences in hardness, toughness and wear resistance of different materials will directly affect the processing efficiency and tool life.
High-speed steel (HSS) tools are suitable for processing soft metals such as aluminum and copper. These materials have low hardness, and the use of HSS tools can achieve good cutting results. High-speed steel tools can withstand certain heat and impact due to their good toughness and wear resistance, and are suitable for applications with lower cutting speeds.
For medium-hard materials such as low-carbon steel and alloy steel, carbide (WC-Co) tools are usually selected. Carbide tools have superior wear resistance and thermal hardness, and can maintain cutting performance at higher cutting speeds. This type of tool can effectively reduce tool wear and extend service life during processing. Carbide tools are suitable for a variety of processing forms, including milling, turning and drilling, and have strong adaptability.
When it comes to hard materials, such as stainless steel and titanium alloys, ceramic tools and composite tools are preferred. Ceramic tools have extremely high hardness and heat resistance, but are more brittle, so they are suitable for high-speed cutting at lower feed rates. They are often used for finishing and can achieve excellent surface finish and dimensional accuracy. Composite tools provide higher cutting performance and toughness by combining the advantages of different materials, making them ideal for machining difficult materials.
