Question

Which one of the following CANNOT impart linear motion in a CNC machine?

Correct answer (D) Chain and sprocket Solution Linear motors, ball screws, and lead screws are standard mechanisms used to provide precise linear motion or convert rotary motion to linear motion in CNC machines. A chain and sprocket mechanism is primarily used for power transmission between parallel shafts and lacks the precision, rigidity, and backlash control required for the linear axes of a CNC machine.
