Vehicle CG159 series of semi-automatic lathe machine is headed, according to the diameter of the pipe to be machined tire design special card to the outside diameter of positioning, automatic chucking tube, the ends of the tube within the orifice only processed simultaneously, as a result of the pipe is the same at a the center of rotation, so you can be strict control on the process to be machined workpiece diameter and bore concentricity, roller machining length produced according to user needs, not less than the minimum roller 200mm. The machine is fully electrical and hydraulic control by PLC, switch to a different length of the roller tube machine without having to adjust the machine, workers will be processed by hand into the machine material on the shelves, pressing machine control knob, will achieve automatic Chucking, feed retract, blanking. Because the machine design rigorous, and therefore very efficient, skilled workers can be a middle class 350-450.
