CNC Skiving and Roller Burnishing Machine For Deep Hole Cylinder
DSBK-150 DSBK-200 DSBK-250 DSBK-360 DSBK-500
Machine Summary:
*The CNC skiving roller burnishing machine is newly developed by our company. This machine has the smart and simple CNC operation system with high efficiency and stable performance, the configuration design is uniform, artistic and clean, using the environmental protection measures against oil splash and leakage.

Performance and Features:
*When processing, the workpiece is fixed and the tool is rotated. 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 procssing 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 ordor: 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 ratary 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.
