HAN Hai-qun1,LI Chun-yan 2(1.Jiangsu Hengli Combined Machine Tool Company Ltd.,Jiangsu Yancheng 224055,China;2.UGS College of Yancheng Institute of Technology,Yancheng Jiangsu 224051,China)  
To ensure the accuracy of three kinds of holes of crankshaft,camshaft and idlers,a triaxial fine boring machine for the WD12 cylinder is designed.The singleside horizontal boring is determined which include the overall program machining sketch chart and electrical action cycle table The holes of crankshaft and camshaft are long with intermittent gap and high precision To improve the rigidity of boring bars,some methods are applied.They include making the boring bar thicker,adding the intermediate support,choosing the line boring bars and floating holders of Mapa,and selecting the precision rotary bushings of GATCO.Put to use the fixing scheme of "one plane and two pins" and hydraulic clamping facility and make a specific request of installation requirements of the boring mold in the machine.After ten months of research,the boring machine get user's acceptance
