A stepper motor lead screw coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. On CNC Router, it is commonly used to connect driving and the driven parts on Z axis if x and y via rack and pinion transmission, one side with driving motor shaft(stepper or servo motor), the other side with ball screw shaft. And if the cnc router machine using lead screw transmission on X Y and Z, then the flexible shaft coupler can be used on X and Y axis also.     


One set of cnc flexible coupling (coupler) should be consisted by the parts as picture in below
