Metal CNC Processing Tzk50A CNC Deep Hole Scraping and Rolling Machine

Product Description

Metal CNC Processing TZK50A CNC Deep Hole Scraping And Rolling Machine
TZK50A CNC deep hole scraping and rolling machine is adopted for the processing cylinder in batch. By use scraping rolling 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 structure.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.
