Materials and Coatings of Carbide Turning Inserts

Carbide turning inserts are crafted primarily from a robust mix of tungsten carbide and cobalt, a combination that ensures exceptional hardness and resistance to wear, even under high temperatures. This resilience makes them invaluable for precision turning operations across various industrial applications.

Coating Types and Their Advantages:

  • Titanium Nitride (TiN):

    Known for its golden hue, TiN coating enhances hardness and resistance to wear, making it versatile for both ferrous and non-ferrous materials.

  • Titanium Carbonitride (TiCN):

    Offers superior hardness and wear resistance, suitable for high-speed machining of ferrous materials. Its dark grey appearance is coupled with excellent thermal stability.

  • Aluminum Oxide (Al2O3):

    This coating excels in high-speed and high-temperature conditions, providing superb crater resistance. It is often used alongside other coatings for enhanced performance.

  • Titanium Aluminum Nitride (TiAlN):

    A premium coating that improves hardness, wear, and oxidation resistance, ideal for machining high-temperature alloys and stainless steel.

Selecting the right coating depends on the machining material, operation type, and specific performance requirements. Consulting with experts can help determine the best coating for a particular application.

Shapes and Sizes of Carbide Turning Inserts

Carbide turning inserts are available in a variety of shapes and sizes, tailored to specific machining needs:

Insert Shapes:

  • Square

    Characterized by their 90-degree cutting edges, square inserts are versatile and commonly used for general turning and facing operations.

  • Triangular

    These inserts have three cutting edges and are optimal for both roughing and finishing tasks due to their shape and efficiency.

  • Round

    Round inserts are ideal for operations requiring high levels of maneuverability and are excellent for creating smooth finishes.

Insert Sizes:

  • Size Indication

    Characterized by their 90-degree cutting edges, square inserts are versatile and commonly used for general turning and facing operations.

  • Choosing the Right Size

    Larger inserts are preferred for better stability and are recommended for heavy machining. The choice of size should also consider the tool holder, entering angle, and the specifications of the machine being used.

Each shape and size of insert has specific advantages, affecting cutting performance, chip control, and the surface finish of the machined part. The selection of the appropriate insert shape and size is crucial for optimizing the machining process.
