Hybrid Processing by Turning and Burnishing of Machine Components

摘要

The paper presents a method of hybrid manufacturing process of long shafts and deep holes by simultaneous turning and burnishing method. The technological results of the research focus on the influence of the basic technological parameters of this process on the surface roughness of piston rods of hydraulic cylinders. Research results are presented in the graphs as well as mathematical formula. Set of samples were made of steel (C45) as a rod with slenderness ratio (l/d) 5-20 and a diameter 56 mm. It shows as well the original CNC machine, which can perform hybrid process (turning and burnishing) of rods and shafts which diameters are in the range 20-100 mm and maximum length 1750 mm.
