Kyocera Carbide Inserts - CNMG

1. Overview of Kyocera CNMG Carbide Inserts

Kyocera’s CNMG carbide inserts are diamond-shaped with an 80° point angle, featuring a negative rake angle and multiple cutting edges. This multi-edge design maximizes tool life and improves cost-effectiveness, making them a popular choice for high-volume and high-speed machining. These inserts are engineered to provide excellent performance across various materials, from steels to high-strength alloys.

• Shape: Diamond-shaped insert with an 80° point angle.
• Cutting Edges: CNMG inserts typically offer four cutting edges, maximizing tool life and reducing the frequency of tool changes.
• Geometry: Negative rake angle for better chip control and stable cutting performance in heavy-duty applications.

2. Key Features of Kyocera CNMG Carbide Inserts

• Multi-Edge Design: Kyocera CNMG inserts have four cutting edges, allowing for extended tool life. As one edge wears out, the insert can be rotated to use another edge, reducing the frequency of insert replacement and cutting costs.

• Superior Wear Resistance: Made from high-quality carbide material, these inserts offer exceptional wear resistance, which ensures longer tool life and reduced downtime in production settings.

• Precision and Consistency: Kyocera CNMG inserts provide consistent cutting performance, producing high-quality surface finishes and tight tolerances, which are critical for precision machining applications.

• Negative Rake Angle: The negative rake angle design provides better control over the cutting forces, especially during heavy-duty turning operations. It helps in reducing vibrations and improving the stability of the cutting process.

• Excellent Chip Control: These inserts feature optimized chip-breaking geometry, ensuring smooth chip flow and preventing chip clogging, especially in tough-to-machine materials.

3. Applications of Kyocera CNMG Inserts

• Turning Operations: Kyocera CNMG carbide inserts are ideal for general-purpose turning, including roughing and finishing operations. The negative rake and multi-edge design provide stability and chip control during turning processes.

• Grooving and Profiling: CNMG inserts are also used in grooving and profiling tasks where precise cuts are required. Their strong, stable geometry helps achieve clean, accurate grooves and profiles.

• Heavy-Duty Cutting: The rugged design of Kyocera CNMG inserts makes them perfect for heavy-duty cutting tasks. They can withstand high cutting forces, making them suitable for high-stock removal operations in materials like steel, stainless steel, cast iron, and non-ferrous metals.

• Precision Finishing: For finishing operations, Kyocera offers specific grades and coatings that optimize the surface finish of the workpiece, making CNMG inserts a versatile choice for both roughing and finishing in the same operation.

4. Grades and Coatings

Kyocera offers a range of insert grades and coatings for CNMG inserts, providing solutions for different materials and cutting conditions:

• CVD Coatings: Kyocera’s Chemical Vapor Deposition (CVD) coatings enhance the hardness and wear resistance of carbide inserts, making them highly effective for machining steel, stainless steel, and cast iron at higher cutting speeds and temperatures.

• PVD Coatings: Physical Vapor Deposition (PVD) coatings are available for materials that require excellent surface finish and heat resistance. PVD-coated inserts are ideal for finishing applications and cutting tough materials like hardened steels or superalloys.

• Specialized Grades: Kyocera offers carbide grades tailored to specific applications, including those requiring high toughness, thermal stability, or excellent wear resistance for tough-to-machine materials.

5. Advantages of Kyocera CNMG Carbide Inserts

• Long Tool Life: The multi-edge design and superior carbide material contribute to a long tool life, reducing the frequency of insert changes and associated costs.

• Cost-Effective: By utilizing all four cutting edges, Kyocera CNMG inserts help reduce tool consumption, leading to lower cost per part and improving productivity in mass production settings.

• Improved Surface Finish: The stable cutting geometry and optimized coatings ensure a superior surface finish, even in high-speed machining conditions, making these inserts ideal for both rough and fine machining.

• Reduced Downtime: Kyocera CNMG inserts provide excellent durability and wear resistance, reducing downtime for tool replacements and contributing to continuous, efficient production.

• Wide Application Range: With various grades, coatings, and geometries, Kyocera CNMG carbide inserts can be used across a wide range of materials, including steels, cast irons, stainless steels, and non-ferrous metals.
