[0008] As a further limitation of this technical solution, the moving component includes a linear module as a moving platform for the electric tool post. The electric tool post is mounted on the slide plate of the linear module for achieving precise movement of the electric tool post. The linear module is nested within an upper track of a CNC machine tool.
