CCGT 삽입

• 기음: Shape. The first “기음” signifies a rhombic (diamond) shape with an 80-degree included angle.
• 기음: Clearance Angle. The second “기음” indicates a 7-degree positive clearance angle.
• G: Tolerance. “G” denotes a medium tolerance range, though other precision tolerances may exist.
• 티: Chipbreaker Style & Hole Configuration. This letter designates both the chip forming geometry and whether the insert has a central hole. Chipbreaker variations are numerous and manufacturer-specific.
• 숫자 숫자 :
  • 처음 두 자리 : Inscribed circle (IC) diameter in millimeters. Divide this by 25.4 to get the approximate inch equivalent.
  • 다음 두 자리 : Thickness in millimeters. Divide by 25.4 for the inch conversion.
  • 마지막 두 자리 : Nose radius in millimeters. Also divide by 25.4 for an inch approximation.

CCGT Carbide Inserts

Virtually all CCGT inserts are made from carbide-based materials. Here’s what you need to know:

• Substrate: The core carbide material determines the insert’s fundamental properties like toughness and wear resistance. Different compositions offer suitable balances for various applications.
• 코팅: Thin layers of advanced materials like TiN, TiAlN, CVD, or PVD are applied to the carbide substrate. These coatings enhance wear resistance, reduce friction, and improve performance in specific materials.

The Importance of Grade

Choosing the right carbide grade (substrate + coating) is crucial. This is matched to the workpiece material you’re cutting:

• 강
• Stainless Steels
• Cast Iron
• Non-ferrous metals (like aluminum)
• Hardened Materials
