1.The major basic parts such as the lathe bed, lathe feet, the middle supporting plate, the spindle

box are all made of HT300 cast iron. The lathe feet is box type structure with symmetric

compact and reasonable structure which ensures the basic parts of the high rigidity and bending

resistance performance; The inside grid reinforced of lathe bed effectively ensure the rigidity and

accuracy of the Z axis strong cutting force. The basic parts are polished by resin sand and aging

treatment, and the surface of bed ways treated by supersonic frequency quenching up to 2mm,

which ensure machine’s long-term stability when working.

2.The feed of X, Z direction adopts the inner loop preloading largelead ballscrew with double

nut so it is of high feed speed. The drive motor connect with screw straightly via elastic

coupling. The feed servo motor passes power to the high precision ball screw directly . It is no

gap, and it ensures the accuracy of positioning and synchronization for the lathe.
