TGG250 CNC Deep hole scraping rolling machine
Brief introduction of TGG250 CNC deep hole scraping rolling machine(other models are available,please email to get details)
CNC Deep hole scraping rolling machine efficiency is 5-8 times higher than ordinary deep hole and boring. It is the professional processing equipment for the manufacture of hydraulic cylinders. His rough boring and fine boring soluble one, push boring at once coarse and fine boring, boring after the use of the firming of the retraction f inished rolling process. After r olling process, th eworkpiece roughness reached Ra0.4.
Deep rolling processing is non-cutting processing technology , which is used to make the inner space reach ed the required surface roughness by plastic deformation.
The machine tool is composed by the bed body, head of a bed frame, feeding oiler, oiler feeding system, boring bar, boring bar drag plate feeding system, the work support, boring bar support, work calipers, chip removal filter system, hydraulic system, cooling system, CNC electrical system, automatic lubrication system and other major parts.
