The lathe body 1 is provided with two groups of chip removal assemblies 100, each chip removal assembly 100 comprises a chip removal motor 1001 and a chip removal screw 1002, each chip removal groove 10 is internally provided with one chip removal screw 1002, the chip removal motors 1001 are fixed on the side wall of the lathe body 1, and the output shafts of the chip removal motors 1001 are fixed with the chip removal screws 1002. Two chip removal pipes 17 are fixed on the side wall of the machine body 1 far away from the chip removal motor 1001, and the chip removal pipes 17 are communicated with the chip removal grooves 10. The chip removal motor 1001 drives the chip removal screw 1002 to rotate, and the chip removal screw 1002 conveys the chips falling into the chip removal groove 10 out of the chip removal pipe 17. The lathe body 1 is provided with two chip removal grooves 10, and two chip removal screws 1002 are used for removing chips, so that chips are not easy to accumulate.

Baffle 18 is fixed with all around of lathe bed 1 top surface, and baffle 18 can reduce the subaerial possibility that iron fillings drop.

The implementation principle of the high-speed precise horizontal five-axis linkage aero-engine blade numerical control milling center provided by the embodiment of the application is as follows: during operation, firstly, a workpiece is clamped between the first rotating shaft 811 and the second rotating shaft 821, then the workpiece is processed, the upright column 2 and the sliding seat 4 can slide along the X-axis guide rail 12, the sliding seat 4 drives the spindle box 44 and the tool spindle 45 to move along the Z axis, the Y-axis sliding support seat 6 can drive the workpiece to move along the Y-axis guide rail 15, and a knife on the tool spindle 45 processes the workpiece. The chip falls into the chip flute 10 and the chip removal screw 1002 transports the chip from the chip flute 10 out of the chip flute 10.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
