[0029] In actual use, when it is necessary to perform inner hole processing on disk-type parts, the inner hole is deep and has a large diameter, and the tool needs to be moved to a deeper position. The tool is moved above the part through the horizontal component 33. After adjusting the position of the tool, the vertical component 31 is controlled to drive the crossbeam 32 to move, so that the turret 4 moves close to the part to facilitate processing of the part surface. When performing inner hole processing, the nitrogen cylinder 36 is controlled to retract its piston rod, and the bracket 37 moves downward under the drive of the piston rod. Since the ram 38 and the bracket 37 are fixedly connected, the ram 38 moves downward, thereby driving the turret 4 equipped with the tool to move downward, so that the tool penetrates deep into the workpiece for feed processing, reducing the difficulty of processing and improving processing efficiency.

[0030] Specifically, the transverse component 33 includes a transverse motor 331 fixed on the side of the beam 32.

[0034] More specifically, the front cross-section of the material chute 5 is a trapezoid that is wide at the top and narrow at the bottom, and a receiving box 8 is slidably connected to the bottom of the material chute 5 for receiving the coolant and chips. In actual use, the material chute 5 is set to a trapezoid that is wide at the top and narrow at the bottom, so that the chips and coolant slide down along the wall of the material chute 5, and a receiving box 8 is set at the bottom of the material chute 5 for receiving the chips and coolant.
