PRODUCT DETAIL

The Introduction of Tipped PCBN Insert

• TPGW is an 60-degree triangle insert with a 11-degree relief angle. It 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 commonly used in finishing and semi-finishing cast iron and hardened steel. It is commonly used as boring inserts. Common used material grades are as follows:

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

• TPGW compound PCBN inserts are conventional ISO standard triangular inserts. Commonly used models are TPGW0902，TPGW1102, TPGW1103, TPGW1603, TPGW16T3, TPGW160404, etc. Standard cutting edges are 3 tips, and radius can be 02,04,08, standard inserts have 3 tips, common chamfer is S01020, S01025, S01325, ect. Other non-standard cutting edges, radius and chamfer can be customized.

• TPGW composite PCBN inserts are often used for finishing and semi-finishing quenched workpiece, such as gear inner holes, gear end faces, gear outer circles and gear shafts, etc., as well as gray cast iron workpiece, such as brake discs, brake drums, engine blocks, etc.

  
  

• When machining hardened steel, TPGW 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.
