CNMG-GH

ZANHO CNMG-GH series is a high-performance 80° rhombic turning insert specifically engineered for difficult-to-machine materials. Optimized for HRC40-65 Hardened Steel, High-Temperature Alloys, and Bearing Steel, the specialized GH chipbreaker provides exceptional edge stability at micro-feed rates (0.02-0.2 mm/r). It is the ideal solution for precision hard part turning where thermal resistance and superior surface integrity are critical.

Description

Key Performance & Features

  • Hardened Steel Specialist: Specifically designed for machining materials with hardness ranging from HRC40 to HRC65, including quenched and tempered steels.
  • Precision Hard Part Turning: Optimized for finishing and semi-finishing of bearing steel and high-temperature alloys with extreme dimensional accuracy.
  • Stable GH Chipbreaker: Engineered to provide reliable chip control and prevent edge micro-chipping even at extremely light feed rates (as low as 0.02 mm/r).
  • Superior Heat Resistance: Advanced substrate and coating technology ensure extended tool life under the high thermal loads typical of hard metal cutting.
