TGK25 TGK35CNC deep hole skiving and burnishing machine is burnishing for the processing cylinder in batch.By using skiving roller burnishing technology used in a variety of cylinder bore surface can precision processed.It can also be used for hot rolling cylinder boring-scraping-rolling finishing machining.The precision can reach IT7-IT10 and the roughness of surface below Ra0.2-0.4µm.
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 structrue.The filtrate method is chip conveyor-magnetism separator-fine filtration three grade and the filtrate precision can reach 50µ.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.
