CNMN series CBN inserts have a shape of 80° rhombus, and the main cutting edge relief angle is 0°. They can be called CNMN/CNGN. The inserts are non-porous and synthesized by polycrystalline cubic boron nitride at high temperature and ultra-high pressure, and are called CBN solid inserts. , has excellent heat resistance, wear resistance and chemical stability.
CNMN series common CBN insert models are CNMN0904, CNMN1204, CNMN1207 and so on.
Standard cutting edges are T01020, T01025, T02020, T02030, S01020, S01025, S02020, S02030, other non-standard cutting edges can be customized.
CNMN inserts can be equipped with 90°, 95°tool holders, cylindrical turning tool holders, inner hole turning tool holders, etc. There are three types of L, R, N. Such as CCGNR/L, CCLNR/L.

CNMN solid CBN inserts can efficiently turn various cast iron and hardened steel parts, and realize turning instead of grinding. It is often used for turning gray cast iron brake discs, gray iron brake drums, boron cast iron cylinder liners, cast iron clutches, cast iron pressure plates, gray cast iron flanges, air conditioning compressors and other typical cast iron parts. Slurry pump and other parts.
When using the solid CBN insert to process the slurry pump sheath, it is not affected by slag inclusion and blisters. And it is used for the processing of the impeller of the slurry pump, which is capable of strong intermittent cutting. After the surface of the workpiece is processed with a coated tool or a ceramic tool, the surface is hot to the touch, but after processing with an solid CBN tool, the hand feel is warm, because the chips can be well discharged during the processing to remove the cutting heat.
CNMN120408 CBN inserts can also process HRC58-62 hardness 20CrMnTi gears, cutting depth ap=0.2mm, line speed Vc=150m/min, feed f=0.06mm/r. The use of solid CBN inserts CNMN processing can greatly improve the processing efficiency, and is a good choice for processing workpieces with general accuracy requirements.
No matter how harsh or difficult the processing conditions are, SCBN TOOlS strives to provide users with the most available and economical processing solutions.
