2MK2120.2125.2135 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. 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 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 Ra0.2-0.4 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.
