After a decade spend in develop CNC machine, Ko Tung expects to extend the market and establish the status in machinery industry. Therefore, Ko Tung starts to invest center spindle both ends simultaneous turning CNC lathe. The original idea is to design as automation operation system to work with pipe fitting type turning machine. The concept of this type CNC machine jumps outside of the box of hardware type processing pattern. This can proceed the bore turning process on mandrel and pipe type products and proceed the process on two-sides at the same time. No need to change the workpiece and readjust the center position.
