The machining method of this machine tool is the boring method, which is push boring with forward chip discharge. The oil is supplied by the oil feeder and directly transported to the cutting area through a dedicated oil pipe. Processing is carried out using a chuck and top plate clamping method, with the workpiece rotating and the boring bar performing Z-axis feed motion.
