Platform Dimension of platform 4500×1800×400 Area (length ×width) 3600×4500mm Maximum loading capacity 15t/㎡ 6. Overall dimension of the machine (length × width × height) 10200×8802×7000mm 7. Overall weight 85t This machine is applies to the coarse and fine processing as well as drilling and reaming processing of surface and hole for large, heavy and over heavy complex components. It is suitable for general machinery manufacturing industry, especially for single pieces and small batch production of high precision and complex components. It has features of reducing manufacture number of process equipment and shortening production preparation period. The machine can complete the processing of milling, boring, turning, drilling and hole boring only in condition that workpiece is prepared on machine. This machine uses circular interpolation process (x, y coordinate axes) as well as small diameter milling cutter which can process any plane curve type surface. The adoption contouring control method for milling of inclined plane, square plane and big hole end plane narrowed operating space, improved production efficiency and relieve labor intensity. This machine is equipped with high precision rotary work table and square-edge milling head and other functional components which can complete the processing of pentahedron. |
