• Size: Available in common sizes such as 12 mm x 12 mm, 16 mm x 16 mm, and 20 mm x 20 mm depending on the required cutting depth and application.
• Insert Type: Positive rake angle for smooth cutting and low cutting forces, ideal for both roughing and finishing operations.
• Cutting Edges: Four usable cutting edges, which can be rotated to extend tool life and reduce tooling costs.

2. Key Features of TaeguTec TNMG Knife Inserts

• Positive Rake Angle: The positive rake angle of the TaeguTec TNMG knife insert reduces cutting forces and ensures smoother cuts, leading to less vibration and improved surface finishes. This is particularly advantageous in turning operations where maintaining stability and precision is essential.

• Multi-Edge Design: The multi-edge design of the TNMG knife insert means that the insert offers four cutting edges for extended use, which improves cost-effectiveness by reducing the frequency of insert changes and lowering overall tooling costs.

• Versatility: The TNMG knife inserts are designed for a wide range of applications, from roughing to finishing. They can be used in diverse industries, including automotive, aerospace, medical, and general manufacturing, and are effective on materials like carbon steels, stainless steels, cast iron, and non-ferrous metals.

• Enhanced Chip Control: The unique geometry of the TNMG knife insert helps in effective chip management. This is critical for maintaining smooth cutting processes and ensuring high-quality surface finishes, even during heavy-duty or high-feed-rate cutting operations.

• Durability and Wear Resistance: Manufactured from high-performance carbide material, the TNMG knife insert offers superior wear resistance, allowing it to maintain its cutting edge over extended periods. The insert is capable of withstanding the heat and pressure generated during high-speed cutting operations, providing longer tool life and reduced downtime.

3. Applications of TaeguTec TNMG Knife Inserts

The TaeguTec TNMG knife insert is highly versatile, making it suitable for a wide range of applications. These inserts are particularly useful for turning, profiling, grooving, and facing operations across various industries.

• Turning Operations: The TNMG knife insert is highly effective for both external and internal turning tasks. Its geometry ensures stable cutting with minimal vibration, which is critical when working with tough materials or higher feed rates.

• Facing: The positive rake angle of the insert makes it perfect for facing operations, ensuring smooth and precise surface finishes even in the most demanding cutting environments.

• Grooving: These inserts excel in grooving applications, where narrow cuts or slots are required. The multi-edge design ensures efficient chip removal, reducing the chances of clogging and enhancing overall machining performance.

• Profile Turning: The TNMG knife insert is also well-suited for profile turning tasks, where the insert follows specific contours and profiles. The stability of the cutting edge ensures smooth operation, and the extended tool life helps to reduce the frequency of insert replacements.

• General-Purpose Machining: Due to its versatility, the TaeguTec TNMG knife insert can be used for a wide range of general-purpose turning applications, from roughing to finishing, across various industries.

4. Grades and Coatings for TaeguTec TNMG Knife Inserts

TaeguTec offers a range of grades and coatings for the TNMG knife inserts, allowing users to select the most appropriate option based on the material being machined, the cutting conditions, and the desired performance characteristics.

• CVD (Chemical Vapor Deposition) Coatings: CVD coatings are perfect for high-temperature applications, providing superior wear resistance and heat resistance. These coatings are ideal for machining hard-to-machine materials like stainless steel, cast iron, and high-alloy steels. The CVD-coated inserts are particularly useful for heavy-duty roughing operations.

• PVD (Physical Vapor Deposition) Coatings: PVD coatings provide a thinner and more uniform coating layer, offering enhanced surface hardness and wear resistance. These coatings are well-suited for finishing applications and offer excellent results when machining materials like aluminum, brass, and non-ferrous metals.

• Grades:

  • K10: Suitable for general-purpose machining in materials such as carbon steel, mild steel, and cast iron. This grade is known for its good balance of toughness and wear resistance.
  • K20: Ideal for medium-duty applications in stainless steels, tool steels, and high-strength alloys. It offers excellent thermal stability and wear resistance.
  • M15: A premium grade for high-speed cutting in tough materials, offering excellent wear resistance and heat resistance for heavy-duty operations.

5. Advantages of TaeguTec TNMG Knife Inserts

• Extended Tool Life: With the multi-edge design, TaeguTec TNMG knife inserts provide longer tool life by offering more usable cutting edges. This helps reduce tooling costs and the frequency of insert changes.

• Cost Efficiency: The multi-edge design and high-quality coatings reduce the need for frequent insert replacements, making the TNMG knife insert a cost-effective solution for both small and large-scale production runs.

• High Productivity: The insert’s ability to operate at higher cutting speeds and feed rates, while maintaining stability and performance, leads to increased material removal rates and shorter cycle times.

• Superior Surface Finish: The positive rake angle and sharp cutting edges contribute to better chip control, resulting in smoother cuts and high-quality surface finishes in both roughing and finishing operations.

• Reduced Vibration: The stable cutting geometry and multi-edge design contribute to reduced tool vibration, even in high-feed-rate and high-speed operations, improving both the precision of the cut and the surface quality of the workpiece.
