description A machine tool used for machining crankshaft oil holes comprises a machine tool body and a clamp used for clamping a crankshaft. Guide rails and a workbench are arranged on the upper portion of the machine tool body, the guide rails on the left and the right of the workbench are respectively provided with an executing device capable of moving along the guide rails, the executing devices are controlled by a control device, a drill bit is driven to rotate by a driving motor, and feeding is achieved through a stepping motor. A drill jig frame fixedly provided with a drill jig sleeve is arranged on the workbench, a guide through hole for the drill bit to pass is formed in the drill jig sleeve, the axis of the guide through hole coincides with the axis of the drill bit installed on the executing mechanism, and the diameter of the guide through hole is consistent with the largest work outer diameter of the drill bit. In the working process, the drill bit starts to drill holes after penetrating through the guide thr
