Abstract
An improved pneumatic ADE-machine with a built-in logic has a clutch in the power transmission chain between a first drive gear and a second driven gear. The clutch includes two clutch parts (D, F), whereof a first part (D) is axially biased by a spring (C). Movable elements (E) are arranged between the clutch parts, which transfer the rotation from the first to the second clutch part, and an actuator (H) is arranged in connection with the first spring biased clutch part (D). When a feed force on a drill during drilling exceeds the biasing force of the spring, the movable elements displace the spring biased clutch part axially, which triggers the actuator (H) to send a corresponding signal to the machine logic.
