As time advanced processing technology continues to improve, roughing and finishing titanium alloy material removal rate is also rising. As can be seen, titanium alloys improved curve flattens, has limited its room for improvement. Processing efficiency can be further improved, the need to adopt a new processing technology. Taking into account the increasing proportion of titanium and composite materials in aircraft structural materials, improve the efficiency of the processing of these materials is essential. The following is a drilling process tool composite / metal laminate material possible areas for improvement: (1) higher hardness, toughness and better material grades; (2) functionally gradient materials (in different parts of the tool to customize the different cutting performance); (3) nanotechnology (nano-structures); (4) different composition (such as non-cobalt based binder); (5) self-lubricating ability (can be used for dry or nearly dry cutting); (6) a lower tool cost of materials; (7) the lower tool manufacturing and regrinding costs; (8) improved coating bonding method.
