The machining method is the workpiece fixed and the tools rotate and feed.The bed of machine is double rectangle guideway. The guide carriage is move on the linear guideway by the hydraulic and the workpiece is fixed by taper hole position.It adopts Taiwan Yongzhen hydraulic station.The colling system is ground oil tank structure.The filtrate method is chip conveyor–magnetism separator–fine filtration three grade and the filtrate precision can reach 50 μ. The CNC system is Germany SIEMENS system. The length of cylinder below 3m is feeded by the lead screw and over 3m is by gear–racked. The efficiency of processing is 3–5 times of traditional deep hole machine if use the Germany Wenaroll high efficiency auto combination tools.
