At present, most of the jigs used for drilling the crankshaft end face on the machining center are directly borrowed from the jigs used in the previous radial drilling machines, and have not been redesigned. Because the positioning of the jigs was all manually adjusted before, the machining process is labor-intensive and the production efficiency is low. The versatility is poor, and different types of crankshafts need to be equipped with different sets of fixtures.
