And a dead head cutting machine is used for cutting off the dead head, and a cutter of the dead head cutting machine is arranged on the cutter holder mechanism. Before machining, the cutter and the cutter holder need to be arranged on the feeder head cutting machine at a position close to the feeder head, and the space between the feeder head cutting machine and the propeller casting workpiece is limited. During cutting machining, the cutter holder mechanism of the dead head cutting machine is subjected to large cutting force, and the size and the weight of the cutter holder mechanism are large for ensuring rigidity. Due to the large size, weight and limited operating space, the toolholder mechanism is difficult to install in place.
