| Abstract: | Problems of heat dissipation and drill tip strengthening become intensified when deep-hole drilling on manganese steel, due to the higher cutting resistance and poorer heat conductivity of this material. The characteristics of manganese steel drilling are investigated and a novel drill point is developed. Industrial on-line tests, for drilling a slant oil hole on a crankshaft of manganese steel, confirm that drill life is improved by 33% in comparison with that of a conventional drill point. |
