Effects of Additives and CBN Grit Size on the Machinability of PCBN Tools

Abstract:

Article Preview

An investigation was reported on how to improve the machinability of PCBN tool for realizing the electric spark line cutting of PCBN tool. The machinability of the PCBN tool was evaluated in terms of its current conductivity. The influences of the additive compositions, additive concentrations and grit sizes of CBN on the current conductivity of PCBN tool were discussed through manufacturing PCBN tool. Experimental results indicated that the machinability of PCBN tool was attributed to the mesh structure of current-conducting additive, which was the combined effects of high additive concentrations and fine CBN grits.
