Machine tool for machining center holes of shaft parts

The utility model relates to the technical field of shaft part center hole machining, in particular to a shaft part center hole machining machine tool which comprises a machine tool body, a first sliding rail pair is arranged on the top face of the machine tool body in the length direction of the machine tool body, and a clamping mechanism used for clamping a shaft part is arranged on the top face of a moving part of the first sliding rail pair. The two ends of the machine tool body are each provided with a machining mechanism capable of machining center holes in the end faces of the shaft parts clamped by the clamping mechanisms. The center holes of the end faces of the shaft parts on the corresponding sides are sequentially or simultaneously machined through the two machining mechanisms, the technical problems that in the prior art, secondary clamping is needed for the shaft parts, the production efficiency is low, and the labor intensity is large are solved, the precision of the shaft parts is affected due
