How many types of CNC inserts are?
As the mainstream product in the field of modern metal cutting applications, CNC inserts are of various types and widely used. According to different classification standards, CNC inserts can be divided into many types. They can usually be classified according to their purpose, material and structure:
Classification by purpose
Milling inserts: used for milling processing on CNC milling machines, with different blade shapes and geometric structures, suitable for different milling operations.
Turning inserts: used for turning processing on CNC lathes, including different types of cutting tasks such as inner and outer diameter turning, finishing, and grooving.
Classification by structure
Integral inserts: ground from a whole piece of material, the cutting part can be ground into the required shape according to different uses when used.
Mosaic inserts: can be divided into welding type and machine clamping type. The welded insert is fixed to the cutter body by welding, while the machine clamping insert is fixed to the cutter body by mechanical clamping, which is easy to replace and maintain.
Shock-absorbing inserts: When the ratio of the working arm length to the diameter of the tool is greater than 4, a tool with a special structure is used to reduce the vibration of the tool and improve the processing accuracy. Mainly used in processing occasions such as boring.
Special insert types: including strong clamping, reversible tapping, composite tools, etc. These inserts have specific functions and uses to meet specific processing requirements.

Classification by material
Coated inserts: Coat one or more layers of wear-resistant, high-temperature-resistant, and lubricating coating materials on the surface of the blade to improve the service life and cutting performance of the insert.
Metal ceramic inserts: Made by powder metallurgy with metal as binder and ceramic powder as hard phase. It has high hardness, wear resistance and red hardness, suitable for high-speed cutting and cutting of difficult-to-process materials.
Non-metallic ceramic inserts: Mainly made of ceramic materials such as alumina and silicon nitride. It has extremely high hardness and wear resistance, but poor toughness, and is suitable for processing hard and brittle materials.
Carbide inserts: Made of hard compounds of refractory metals and bonding metals by powder metallurgy. It has the advantages of high hardness, good wear resistance, and high heat resistance. It is the most widely used type of CNC inserts.
Superhard inserts: including cubic boron nitride (CBN) blades and diamond blades. These inserts have extremely high hardness and wear resistance and are suitable for machining hard and wear-resistant materials.
