In actual use, in order to leave space for placing other equipment components, the clamping tooling used for machining and the like is usually arranged on one side of the platform body 1. The embodiment further comprises two groove chip removal mechanisms 3, a table chip removal mechanism 4 and three chip pools 5. One of the groove chip removal mechanisms 3 is arranged on the front side of the platform body 1, and the other groove chip removal mechanism 3 is arranged on the side close to the machining tooling 2 of the platform body 1. The two groove chip removal mechanisms 3 are adjacent to each other. One of the chip pools 5 is arranged at the adjacent position of the two groove chip removal mechanisms 3 and connects the two groove chip removal mechanisms 3. The cuttings at the corresponding ends of the two groove chip removal mechanisms 3 can be discharged into the chip pool 5. The other two chip pools 5 are respectively arranged at the ends away from each other of the two groove chip removal mechanisms 3. The table chip removal mechanism 4 is arranged on the side of the upper surface of the platform body 1 which is not arranged with the machining tooling 2 and is connected to the machining tooling 2 at the upper end and connected to the groove chip removal mechanism 3 on the front side at the lower end.
