A study on Poly-Crystalline Diamond tools for high-precision truing

Abstract

This report deals with high precision and high efficiency truing of poly–crystalline daimond tools by use of molybdenumalloy.Tungsten carbide can be cut ultra precisely with poly–crystalline diamond micro milling tool,which is installed onto a high speed tool spindle with collet chuck.In this case,the micro milling tool should be trued on the machine.
The poly–crystalline diamond tool has been usually ground with diamond wheel or electric discharge machining.But the traing preciseness with conventional methods was not so high and the truing of poly–crystalline diamond tools by molybdenum alloy is proposed and basic reserch was carried out with comparisons of GC,stainless steel.
