Adopting the combined technology of skiving and roller burnishing, the machine gives a good solution for the severe deviation in rough processing of hot roller steel tube, and the inferior straightness in fine processing of cold drawn steel tube. It is mainly used for the compound process of boring and roller burnishing for hydraulic cylinder parts. ●The hole tolerance is up to IT7-8, the surface roughness is up to Ra 0.2-0.4 µm. Its processing efficiency is 10 times of the traditional boring technology and 20 times of ordinary honing machines. The traditional technology usually includes four independent steps in order: rough boring-semi fine boring-floating boring-roller burnishing, which is inefficient and needs a long time. ●This machine is assembled with automated flexible tools control module, using the specialized Korean pneumatic and Germany hydraulic tools system, the stock removal within 0.2-8mm is available to be processed. ●The series machines adopt Germany Siemens 808 CNC system, the spindle box is driven by AC variable frequency motor, with stepless speed regulating, and using spindle bearing with a high rotary precision. ●Feeding box is driven by AC servo motor, with stepless speed regulating. The bed body adopts high quality cast iron, the double track ensures the good rigidity and excellent guiding, with protection structure around. ●The machine is equipped with the automatic chips removal, magnetic separator and paper filter, filtering precision up to 20µm, the coolant can be cleanly recycled and reutilized.Specification Unit DSBK-100 TGK20DSBK-200 Boring dia. rangemmΦ35-Φ150Φ40-Φ200Processing depth rangem1-121-12Machine guideway widthmm500650Spindle center heightmm300350The spindle speed range, gradesr/min5-1200 (stepless)120-1000 (4-shift, stepless)Main motor powerkw3030/60  (variable frequency)Feed speed rangemm/min5-3000 (stepless)5-3000 (stepless)Feed carriage rapid moving speedm/min3/63/6Workpiece clamping diameter rangemmΦ40-Φ150Φ40-Φ300The feed motorNm2736Cooling pump motor powerkw5.5 (two group)5.5 (three group)The hydraulic pump motor powerkw/1.5kw, n=1440r/minCooling system rated pressureMPa2.52.5The cooling system flowL/min200, 200 (two group)100, 200, 200 (three group)Air pressureMPa≥0.4≥0.4CNC systemSIEMENS CNC system2.CNC Deep Hole Skiving Roller Burnishing Machine -- DSBK-250 DSBK-360Application:The CNC skiving roller burnishing machine is newly developed by our company.
