Polycrystalline diamond (PCD) has been used for some years for the machining of abrasive systems such as aluminium/silicon and glass filled polymeric materials. This paper reports on the machining of the highly abrasive composite system of aluminium reinforced by silicon carbide particles and/or alumina fibres using polycrystalline diamond tools.
PCBN tools are artificial cubic boron nitride cutting tools, but also to maintain it at a high temperature characteristics of high hardness, mainly to do with the processing of iron. Cubic boron nitride CBN (Cubic Boron Nitride) is the use of artificially synthesized under high temperature and pressure, and its hardness secondGet Price
Considerably better results are achieved, however, when using man-made polycrystalline diamond (PCD) tool materials. PCD is an aggregate of natural or synthetic diamond grits sintered at high temperature/high pressure generally with a metal catalyst used to promote diamond inter-growth and ensure a dense product.
Using PCD drill bits to process engineering ceramics and stone, the efficiency is high and the processing quality is good. Diamond electrolytic drilling can be used to form cylindrical holes (through holes and blind holes), tapered holes and special holes in various difficult-to-machine conductive materials (mostly sintered cemented carbide). It can be machined on the same tool on a single machineGet Price
Unfortunately, the same attributes that make titanium a perfect metal also make it a perfect bear to cut. Tool wear can run high when machining most titanium alloys, especially those containing high amounts of chromium and molybdenum. Without a sharp edge, tools tend toGet Price

For instance machining ferrous materials with diamond tools usually results in high tool wear due to chemical reaction between steel and carbon particles of diamond tools and graphitisation. Machining at −196 °C using LN 2 reduces both chemically and thermally induced tool wear in machining stainless steel components and significantly increases the tool life  .Get Price
