TDC carbide insert

About TDC carbide insert

Carbide inserts are small, replaceable, high-hardness cutting tools made of tungsten carbide and cobalt, primarily used in lathes, mills, and drills for machining hard materials like steel, cast iron, and alloys. These indexable tools increase productivity by offering high wear resistance and enabling faster cutting speeds, often with multiple edges that can be rotated when worn. [1, 2, 3, 4, 5]

Key Characteristics and Components

• Material: Comprised of cemented carbide, combining high hardness (HRA 89-93) with toughness to resist cutting forces.
• Shapes: Common shapes include Triangle (T), Diamond (C, D), Square (S), and Round (R), each suitable for specific operations like boring, turning, or profiling.
• Designation Code (e.g., CNMG 120408):
• Shape: C (Diamond 80).
• Clearance Angle: N (0).
• Tolerance: M (Tolerance class).
• Type: G (With hole and chip breaker).
• Size: 12 (Approx. 12mm edge length).
• Thickness: 04 (Approx. 4.76mm).
• Radius: 08 (0.8mm nose radius). [1, 6, 7, 8, 9]

Selection Factors

• Material Application: Represented by letters, such as P (Steel), M (Stainless), K (Cast Iron), and S (Heat-resistant alloys).
• Operation: Roughing requires stronger, thicker inserts with larger radii, while finishing requires smaller radii for better surface quality.
• Tool Holder: The insert shape must match the corresponding tool holder's geometry. [6, 7, 10, 11]

Key Advantages

• High Wear Resistance: Lasts 5-100 times longer than high-speed steel.
• High Heat Resistance: Maintains structural integrity at high temperatures.
• Efficiency: Allows for faster production and improved surface finishes. [1, 2]
