The invention discloses a needle machine. The needle machine comprises a machine frame, and a frequency converter, a motor, a needling mechanism and a proximity switch which are arranged on the machine frame. The motor and the proximity switch are both electrically connected with the frequency converter which can drive the motor to work at different frequencies, receive switch signals and conducttime calculation. The needling mechanism is connected with the motor through a crank and a connecting rod. The proximity switch is located on the upper side of the needling mechanism. Halting is manually or automatically conducted; the frequency converter receives a halting signal; the frequency converter continuously reduces the operating speed of the motor; when the halting frequency is reached,the frequency converter records the time interval T between the time when the proximity switch just senses a needle plate and the time when the proximity switch just cannot sense the needle plate; when the proximity switch se
