TNGA160408 PCBN is a high-performance Polycrystalline Cubic Boron Nitride (PCBN) cutting tool insert designed for precision machining of hardened steels, cast irons, and other difficult-to-machine materials. This product is part of the advanced TNGA series, which is engineered to deliver exceptional wear resistance, thermal stability, and cutting efficiency in demanding industrial applications. The TNGA160408 PCBN insert is widely used in automotive, aerospace, and general manufacturing industries for turning, milling, and finishing operations.
Superior Hardness and Wear Resistance
PCBN is the second hardest material after diamond, making TNGA160408 ideal for machining hardened materials with a hardness of 45 HRC and above. Its wear resistance ensures extended tool life and reduced downtime.
High Thermal Stability
The insert can withstand temperatures up to 1400°C, making it suitable for high-speed machining applications where heat generation is significant.
Excellent Chemical Inertness
TNGA160408 PCBN is chemically inert, preventing reactions with ferrous materials during machining. This ensures consistent performance and surface finish.
Optimized Geometry
The TNGA160408 insert features a precision-engineered geometry that enhances chip control, reduces cutting forces, and improves surface finish.
Versatility
This insert is suitable for a wide range of applications, including continuous and interrupted cutting, finishing, and semi-roughing operations.
TNGA160408 PCBN is specifically designed for machining the following materials:
Hardened steels (45-65 HRC)
Gray cast iron
Ductile iron
Powder metals
Superalloys (e.g., Inconel, Hastelloy)
Common applications include:
Turning of crankshafts and camshafts
Machining of brake discs and drums
