Key Advantages
-
Triple-Layer CVD Coating: The TiCN+Al₂O₃+TiN coating stack provides superior thermal stability (up to 900°C) and wear resistance. The alumina layer features single-crystal orientation technology, significantly reducing flank wear during high-speed machining.
-
Optimized Chip Breaker (PM槽型): The PM chip breaker geometry ensures efficient chip control, preventing chip entanglement and improving surface finish quality (Ra ≤ 0.8 μm) for precision components.
-
High-Strength Carbide Substrate: The 4325 grade substrate offers excellent toughness and抗塑性变形能力, making it suitable for both continuous and light interrupted cutting operations.
-
Cost-Effective Design: With 4 cutting edges and extended tool life, the insert reduces tool change frequency and overall machining costs.
Application Scenarios
Ideal for machining a wide range of steel and cast iron workpieces, including:
-
Automotive components (crankshafts, camshafts, gear blanks)
-
Hydraulic parts (valves, cylinders)
-
General engineering structural parts
-
Cast iron housings and brackets
