Embodiment Construction
[0011] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments.
[0012] Such as figure 1 As shown, the present invention discloses a method for improving the clamping accuracy of rough machining of crankshafts, which is characterized in that: on the original process of milling both ends and drilling the center hole, the outer circle process of the big end of the car is added, and the outer circle of the big end of the car is provided. The specific method for the turning tool of the circular process is that after the machine tool is started, the crankshaft blank does not move, and the milling cutter head first feeds and mills the two ends of the crankshaft blank to control the total length, and then the milling cutter head withdraws, and the center drills at the lef...
