PCD Inserts

PCD Inserts
  • Product:PCD Insert
  • Specification:Custom made according to your request.
  • Characteristics:There are hundreds of cutters designed for alloy wheels. Various cutters specialized for different type of wheels are well-designed. Regarding the pin hole problem of c asting which happens in diameter under 1mm, it may be improved by using PCD cutters. We can make special size (custom made) PCD inserts according to changeable types of wheels.PCD is kind of polycrystal material made by carborundum powder with solvent under high temperature and pressure. The hardness (around HV6000) is lower than natural carborundum. Comparing PCD cutter with carbide cutter, its hardness is triple – quadruple higher; wear resistance and tool life is 50 -100 times higher; promoting cutting speed 5 -20 times; roughness may reach Ra0.05μm. PCD cutter brings high cutting efficiency and stable accuracy.

切屑形狀及其形成介紹
工件受刀具之切削後,內部產生了塑性變形,其塑性流動程度之大小直接影響了切屑的形態。一般切屑的基本形態有:不連續切屑、連續切屑和積屑刀口的連續切屑等3種。
