An improved flying cut-off machine is disclosed of the type in which a ram is supported for swinging movement induced by a ram actuating mechanism so as to operate a cut-off die set to cut off lengths from an elongated workpiece continuously emanating from a tubing mill. The improvement comprises the provision of an adjustment member included in the ram actuating mechanism which is interposed between connecting rod end members, one of which is pivotally connected to a motor driven crank and the other pivotally connected to the swinging ram. The adjustment member comprises a shaft having oppositely threaded ends threaded into the connecting rod ends so that a length adjustment can be made to the connecting rod, which in turn provides a simultaneous adjustability feature to both the vertical stroke and shut height of the ram produced by the crank rotation so as to adapt the apparatus to variously configured die sets having differing shut heights and strokes.
