After the worker edits the program, the feeder Continuously and uninterruptedly feed the material into the main spindle of the machine tool in sequence, the positive spindle of the machine tool holds the bar and moves back and forth on the Y axis, and cooperates with the guide sleeve structure of the machine tool (the guide sleeve can be interchanged with the synchronous electric guide sleeve and the linkage guide sleeve, etc.) or The structure without guide sleeve cooperates with the knife row on the slide plate of the Y1 axis group to realize the processing and shaping of the workpiece. If the workpiece is too complicated and cannot be formed at one time on the three axis groups of the positive axis structure of the machine tool, the Z2 axis group can be added to the auxiliary axis of the machine tool to form a four-axis centering machine after cooperating with the three-axis centering machine; or add the Z2 axis group, X2-axis group, cooperate with three-axis centering machine to form five-axis centering machine; or add Z2-axis group, X2-axis group, Y2-axis group, and form six-axis centering machine after cooperating with three-axis centering machine. After such cooperation, it is convenient for the workpiece to be formed at one time, and the processes such as turning, milling, drilling, tapping, engraving, inclined hole forming, and eccentric hole forming are completed.
