The invention relates to a high-speed high-precision digital control automatic wood turning machine applied to batch production of golf tees and bamboo tees from thin bamboo wood bars. The wood turning machine comprises a machine frame, a motor, a machine head seat, a compressed air source and a full-automatic production digital control circuit, and is characterized by further comprising a mechanism mounted on the machine head seat and used for driving the thin bamboo wood bars to rotate, a mechanism for clamping and linearly pushing the bars, a mechanism for pushing a slide barrel and an amount stop lever to loosen a pawl head and an input amount stop head for working, a mechanism for quickly pushing a cutting knife in place and controlling the amount of feed, and a mechanism for moving a planer tool forwards and backwards, wherein the motor and the machine head seat are mounted on the machine frame; and the full-automatic production digital control circuit is provided with first to fourth hall sensors. A control method of the full-automatic production digital control circuit comprises first to fourth steps. The wood turning machine has the advantages of high production rate, sensitivity for response, accuracy for action, short bar cutting time, flexibility for bar clamping, stability for bar pushing, short consumption time and the like.
