CBN

The polycrystalline cubic boron nitride (CBN) inserts offer a cost-effective alternative to the diamond tools. Although CBN’s exceptional toughness/hardness is still less than the diamond-based materials, it remains stable at temperatures of up to 1400°C, whereas diamond starts to decompose at 800°C. Additionally, its chemical resistance to ferrous materials is better than of PCD.
This makes CBN inserts the preferred solution (over diamond) in many applications, especially those that involve the machining of hardened steels (45-72 HRC) of any kind: Case hardened steel, tool steel, heat treated steel, etc. They are compatible with standard tool holders by other, leading manufacturers.
CCGW INSERTS
A line of inserts with a 80° cutting corner angle, and two cutting tips. These inserts have a neutral rake angle, and a relief angle of 7°.
Features:

• Wiper geometry versions available

Notes:

• The CCGW 060201 and CCGW 09T301 inserts are only available in CH25 and CK65 grades
• The CCGW 09T302-W wiper insert is only available in CP25 / CP45 / CK65 / CK85 grades

CBN: referred to as cubic boron nitride.
Performance: processing super-hard materials, with high hardness, chemical inertness and high temperature.
It has good thermal stability and wear resistance. The wear resistance is 50 times that of cemented carbide blades, 30 times that of coated cemented carbide blades, and 25 times that of ceramic blades. Mostly used for cutting hardened steel, chilled cast iron and surface thermal spraying materials.
