Abstract: A multi-axis turntable includes a base, a rocker arm and a first driving device capable of driving the rocker arm to rock around the first rotation axis on the base. A swing arm and a second driving device, which is capable of driving the swing arm to swing around the second rotation axis on the rocker arm, are provided on the rocker arm. A workbench and a third driving device for driving the workbench to rotate around the third rotation axis are provided on the swing arm. The second rotation axis and the third rotation axis are parallel to each other or on different planes. Compared with the existing double rotating shaft turntable, the multi-axis turntable of the present invention has a cutting tool system of good and stable rigidity.

Abstract: The invention discloses a double-station gantry combined machining system allowing automatic overturning of workpieces, which comprises a first mobile gantry machining unit, a second mobile gantry machining unit, an overturning platform, a first workpiece fixing table, a second workpiece fixing table and a guide rail, wherein the overturning platform is positioned between the first gantry machining unit and the second gantry machining unit. According to the invention, the system is highly integrated, continuous machining of a gantry machine tool is completed, the working efficiency is improved, and the machining cost of the system is reduced.

Abstract: The invention provides a nested numerical control rotary table, which comprises a large numerical control rotary table, a small rotary table, a large rotary table board and a small rotary table board nested in the large rotary table board, wherein the small rotary table board may be driven by the large numerical control rotary table as a part of the large rotary table board to run together with the large rotary table board, or be driven by the small rotary table to run independently. When the small rotary table board runs independently, the small rotary table is driven to ascend by a lifting oil cylinder, and a pull pin under the small rotary table board and a positioning pin on the small rotary table fixedly connect the small rotary table board with the small rotary table, which are locked by a clamp. The nested numerical control rotary table may complete the tasks of numerical control rotary tables with both large and small dimensions, which saves the production cost and improves the working efficiency.

Abstract: A grinding machine with 5-axis for cutters is disclosed, the grinding machine includes a grinding machine base (12) with an circular upper horizontal surface and a pillar (56) provided on one side of the grinding machine base, the pillar is curved with a radian of 180° along a side edge of the base, a groove body (63) on the circular base is enclosed by a curved vertical plate on the another side edge, and the height of vertical plate is lower than that of the pillar.

Abstract: A vertical turning-milling complex machining center comprises a horizontally-arranged bed body (6) and a vertically-arranged column (7). The bed body (6) is provided with an X-axis lateral supporting linear track (2) and an X-axis guide screw (5). The bed body (6) is also provided with a uniaxial rotating table (1) which can reciprocate and is driven directly by a first external rotor torque motor. The column (7) is vertically provided with a Z-axis lateral supporting linear track (10), a Z-axis guide screw (9) and a crossbeam (11) that reciprocates up and down. The crossbeam (11) is provided with a transverse Y-axis linear track (13), a Y-axis guide screw (12) and a single-pendulum milling head seat frame that can reciprocate along the Y-axis guide screw (12). The single-pendulum milling head is driven directly by a second external rotor torque motor.
