Wear Properties of Diamond-Coated Ball End Tools in Milling of Tungsten carbide

Abstract

It is strongly expected that sintered tungsten carbides, having extremely higher hardness and heat resistance than conventional steel materials, will be utilized widely as molds and dies. In this study the cutting performance of the diamond-coated tools in milling of sintered tungsten carbide is examined through a series of cutting experiments of nine types of sintered tungsten carbide workpieces bonded together in 10wt%, 15wt%, 20wt% or 25wt% cobalt on a 3-axis vertical machining center.
