WCGT0402 WCMT0402 PCD turning and milling insert

Pcd inserts are found at the tips of the tools used for machining non-ferrous metals like aluminum alloy due to their uniform hardness and abrasive resistance. Polycrystalline Diamond (PCD) is a synthetic diamond product that is sintered together in high pressure and temperature conditions in order for it to achieve the uniformly distributed hardness and abrasive resistance. Tipped tools made from this product tend to be strong and resist wear in an exceptional way.

The major benefit of using tipped pcd inserts are that they come at a cheaper price and are economical for one use only. The manufacturing is simpler compared to full faced inserts and it only requires a tungsten carbide base carrier as insert substrate. The substrate has a pocket that accommodates as well as supports the tip. The size and structure of the tips vary with insert shapes. Tipped pcd inserts are most useful for super-fine precision machining for getting a good as well as smooth surface finish. Some of the characteristics of tipped inserts are limited cutting temperature (not more than 700 degrees) and no affinity of the work material with carbon.
