【正文】 troleum and petrochemical industry, select the titanium alloy as the processing objects. This article describes and analyzes the current status deep hole machining process in domestic and foreign , and pointed out the shortings of welding deep hole drilling. Deep hole drilling for the shortings of welding made clipon deep hole drilling machine structure. And select the size of typical structural to design. Put forward the pact tool for the smalldiameter deep holes and the general type of mediumdiameter machining. For the present problems of Deep hole machine tool like expensive and equipment in long period. This paper initially tried to transform and design to transformate the ordinary lathe machine to a deep deep hole machining. Key word； Deephole Tools， Chipin Deephole drilling， Deep Hole Boring Tool， titanium alloy， Machineclip tools I 目 錄 1 緒論
