Experimental Study on the Performance of Titanium Alloy Deep-hole Driller

Zhao Hongbing Zhu LinXi'an Petroleum University,Xi'an,710065  
This paper took titanium alloy deep-hole drilling as a studying object.According to the characteristics difficult to cut of titanium alloy,several cemented carbide tool materials which are widely used in China at present were selected in the tests of machining titanium alloy workpieces.It is determined that deep-hole tool material YT726,whose attrition characteristics surpasses others,is suitable to cut titanium alloy material through deep-hole drilling tests and when drilling titanium alloy deep-holes,whose diameter is 47.4mm,the optimum geometrical parameters is γ_o=7°,α_o=12°,ψ_r=15°,e=3.8mm.
