【正文】 t its processing is very plicated,and has uncertain precision and low on the adaptive control system, the system to processing the slender shafts with high precision and efficiency under the NC environment was put forward,which can process diversified slender shafts with various precisions. 2 Turning of slender shaft is difficulty in mechanical theoretical formula of machining error in turning of slender shaft is error distributing graph is obtained by research provides theoretical references for predict machining error in turning of slender shaft. The processing characteristics of the slender shaft: ① the Hardness of the slender shaft is poor,when Improper turning is Incorrect, It is easy for the role of cutting force and gravity generated bending deformation, vibration, thus affecting the machining accuracy and surface roughness.② The thermal diffusion of Slender Shaft is poor ,Under the action of the cutting heat resulting considerable expansion of the line,If a fixed support at both ends of the shaft, the workpiece will stretch and bend. ③ Because the shaft is longer, a tool path use long time, tool wear large, thus affecting the precision of the geometry of parts.④ Since using the tool holder to turning Slender Shaft if the support block supporting the workpiece on the part of the two pressure Bushi Dang Will affect the machining accuracy. If the parts which are used to supporting the workpiece have inappropriate
