CNMA insert Introduction:
CNMA Carbide Inserts: The Essentials
- 形狀: Rhombic (diamond) with an 80-degree included angle.
- 間隙角: 0 degrees
- Cutting Edges: Double-sided, offering two cutting edges per insert for cost-effectiveness.
- Chipbreaker Geometries: Diverse range of chipbreaker styles from various manufacturers are available. These are tailored to specific materials and machining operations (roughing, finishing, etc.).
- Key Uses: Primarily used for general turning operations and some facing work on a range of materials.
Common Materials CNMA Inserts are Used For
- Cast Iron: Suitable for many cast iron applications.
Advantages of CNMA Inserts
- 性價比: Due to their double-sided design, offering longer tool life per insert.
- Versatile: The range of grades and chipbreakers make them suitable for many machining applications.
- Strong Geometric Shape: The 80-degree diamond shape provides strength and rigidity for their size.
Important Considerations
- Match the Grade to Your Material: Choosing the right insert coating and substrate composition is crucial for optimal tool life and performance in the specific material you’re cutting.
- Select the Right Chipbreaker: The chipbreaker geometry significantly influences how chips are formed and broken. It should be chosen based on the material and type of machining operation.
