CCMT insert Introduction:

CCMT Inserts: The Essentials
- Forma: Rómbico (diamante) con un ángulo incluido de 80 grados.
- Ángulo de despeje: 7 degrees (positive)
- 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: Ideal for turning, facing, and profiling operations on a range of materials.
Common Materials CCMT Inserts are Used For
- Steels: Various steel grades, including carbon and alloy steels.
- Stainless Steels: CCMT inserts can machine different stainless steel types.
- Cast Iron: Suitable for many cast iron applications.
- Some High-Temperature Alloys: Depending on the specific alloy and grade.
Advantages of CCMT Inserts
- Cost-Effective: Due to their double-sided design and wide availability.
- Versatile: The range of grades and chipbreakers make them suitable for many machining applications.
- Good Chip Control: Well-designed chipbreakers ensure effective chip flow and protect the workpiece, tool, and machine.
- Positive Rake Angle: This promotes efficient cutting and reduces cutting forces in many materials.
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.
- Machine Rigidity: Ensure your machine has enough rigidity and power to handle the cutting forces CCMT inserts can generate,
