The CPMT insert features an 80° diamond shape, which is common for turning and facing operations. The C6 grade carbide material provides excellent wear resistance and toughness for general purpose machining of various materials.

3. Setup & Installation

Proper installation of the carbide insert is crucial for optimal performance and tool life. Always ensure the tool holder is clean and free of debris before mounting the insert.

3.1 Tool Holder Compatibility

Ensure that the tool holder is compatible with CPMT style inserts. The insert's ISO designation (CPMT060204) provides specific details about its shape, size, and tolerance. Refer to the tool holder's specifications for proper matching.

3.2 Insert Mounting Procedure

1. Cleanliness: Before installing, thoroughly clean the insert pocket of the tool holder to remove any chips, dust, or foreign particles. A clean seating surface ensures proper clamping and prevents premature insert failure.
2. Positioning: Place the CPMT insert into the tool holder pocket, ensuring it sits flush and correctly oriented. The 80° diamond shape should align with the pocket's geometry.
3. Clamping: Secure the insert using the appropriate clamping mechanism of your tool holder (e.g., screw, lever, or top clamp). Tighten the clamping screw to the manufacturer's recommended torque specifications. Overtightening can damage the insert or screw, while undertightening can lead to insert movement during machining.
4. Inspection: After clamping, visually inspect the insert to ensure it is securely seated and there is no gap between the insert and the tool holder pocket.

4. Operating Instructions

The HHIP CPMT C6 Carbide Inserts are versatile for various turning and finishing operations. Adhering to proper operating parameters will maximize tool life and achieve desired surface finishes.

4.1 General Machining Guidelines

• Material Compatibility: C6 grade carbide is suitable for general purpose machining of steel, cast iron, and some non-ferrous materials. Refer to grade comparison charts for specific material recommendations.
• Cutting Parameters: Optimize cutting speed, feed rate, and depth of cut based on the workpiece material, machine rigidity, and desired surface finish. Start with manufacturer-recommended parameters and adjust as needed.
• Coolant Usage: Use appropriate cutting fluid to dissipate heat, lubricate the cutting zone, and evacuate chips. This helps extend insert life and improve surface quality.
• Chip Control: The integrated chip breaker on the CPMT insert is designed to manage chip formation effectively, preventing long, tangled chips that can interfere with the machining process.

4.2 Turning and Finishing Applications

The 80° diamond shape and 11° relief angle make these inserts ideal for a range of operations:

• External Turning: Suitable for general turning of external diameters.
• Facing: Effective for machining flat faces perpendicular to the workpiece axis.
• Finishing: The sharp cutting edge and precise geometry contribute to excellent surface finishes, especially when using appropriate feed rates and depths of cut.

5. Maintenance

Proper maintenance extends the life of your carbide inserts and ensures consistent performance.

5.1 Cleaning and Storage

• Cleaning: After use, clean inserts to remove any adhering chips or coolant residue. Use a soft brush or compressed air. Avoid harsh chemicals that could damage the coating.
• Storage: Store inserts in their original packaging or in dedicated insert trays to prevent chipping or damage to the cutting edges. Keep them in a dry environment to prevent corrosion.

5.2 Inspection for Wear

Regularly inspect inserts for signs of wear or damage. Replace inserts when:

• Flank Wear: Excessive wear on the flank face behind the cutting edge.
• Cratering: Pitting or cratering on the rake face.
• Chipping/Breakage: Visible chips or fractures on the cutting edge.
• Built-Up Edge (BUE): Accumulation of workpiece material on the cutting edge, which can indicate incorrect cutting parameters or insufficient lubrication.

Timely replacement of worn inserts prevents damage to the workpiece, machine, and tool holder.
