PRODUCT DETAIL

The Introduction of VNMG tipped PCBN Insert

• VNMG is an 35-degree diamond-shaped insert, which is made of PCBN composite sheet with excellent performance. It is a composite PCBN insert with a carbide base inlaid with a CBN tip. It is often used for finishing and semi-finishing of cast iron and hardened steel. , is a very commonly used cylindrical end face turning insert, the commonly used material grades are as follows:

• VNMG series inlaid composite PCBN inserts are very commonly used turning inserts, which can withstand continuous, intermittent and heavy interrupted machining conditions. There are different types of cbn insert materials for cast iron and hardened steel parts, which can fully meet different customer needs.

  
  

• VNMG composite PCBN inserts conventional ISO standard type 35 degree diamond inserts, commonly used models are VNMG160404，VNMG160408，VNMG160412 etc. This series of inserts can also be customized by double-sided welding according to customer needs, so that 4 cutting edges, nose radius and cutting edges can be customized.

• VNMG composite PCBN inserts are often used for workpiece after hard turning and quenching, such as finishing gear end faces, gear outer circles and gear shafts, etc. The roughness can reach Ra0.4. When batch finishing gray cast iron workpiece, such as brake discs, brake drums , When the engine block is made of composite PCBN inserts, the surface finish is higher, and the efficiency is also greatly improved compared to cemented carbide.

  
  

• When machining hardened steel parts, VNMG composite PCBN inserts can be coated. After coating, the tool life will be increased by 30%-45% compared with uncoated inserts, and the finish will also be improved.
