The article is focused on surface integrity at reaming with high-productive reaming MT3 head made by HAM-FINAL Company. The term surface integrity is the surface condition of a workpiece after being modified by a manufacturing process. A machining process produces a surface characterized by the shape, metallurgy and mechanical properties. These surface aspects clearly indicate that a machined surface is very complex. Obviously, a high-energy input increases the likelihood of metallurgical damage and therefore results in a poor surface integrity which has effect on final product. Taking into account different types of created energy transferred to the tested surface and subsurface layer, the basic factors influencing surface integrity are temperatures, residual stresses, metallurgical transformations and also surface plastic deformation. The aim of experimental part is surface integrity tested on holes by reaming MT3 head during manufacturing process and last aim is find out MT3 head tool-life with their evaluation.
