Internal burnishing tool STR6-25AN220C

roller

The tool for roller burnishing of internal surfaces is installed in the turret head of a CNC turning center or a tool rack on a universal lathe. The surfaces of the parts are processed with an accuracy of Ra 0.1 using speeds corresponding to finishing methods. The presence of an elastic element ensures a constant rolling force at any point of the treated surface. The single-roller run-in is simple and versatile, but requires significant working effort, which is fully perceived by the machine nodes. The change in the size of the surface during rolling and rolling is associated with the crumpling of micro-dimensions and plastic volumetric deformation of the part. The reverse stroke should not be used as a working stroke, because repeated passes in opposite directions can lead to excessive deformation of the surface layer. Running-in increases the fatigue limit of parts by 80% or more, having a beneficial effect on the performance of parts. Reduction of machining costs * Eliminate auxiliary operations and machine tools * Polishing on CNC turning centers and universal lathes • Finish the surface from Ra 0.6 to Ra 0.1 * Economical tool life with carbide rollers and roller recovery
