CH2540 the CBN160C successor with improved tool life
CH2540 is based on a new grade platform using bimodal grain distributions, it contains 65 % cBN of submicron size with 15 µm grains added to the structure. This adds both wear resistance and toughness.
For even tougher application areas (H35 application area) CH3515 has been introduced.
Due to higher terminal conductivity compared with CBN160C, CH2540 requires higher cutting speed to achieve correct temperature in the cutting zone.
If it´s not possible to increase the cutting speed an alternative can be to choose the grade CBN150 that with its structure and low CBN content can handle lower cutting speed and interruptions.
