Main introduction of VMC1270 machining center:

1. Machine tool structure

The design and manufacture of the machine tool conforms to the six basic parts of the ISO international standard machine tool (base, saddle, worktable, column, spindle head, ATC fixing frame). Optimized design on the structure, with high static stiffness and dynamic resistance to deformation.

The spindle has a high rigidity structure, which can be used for high-precision cutting. The spindle motor adopts AC servo technology, which can realize the stepless speed change of the spindle. The pre-stretched structure makes the three axes have better dynamic stiffness and resistance to thermal deformation. The three-axis guide rail adopts imported linear guide rails and sliders, which has high stability of processing accuracy, fast and efficient three-axis ball screw and drive servo motor direct transmission. No accumulated error of transmission, high repeatability and high positioning accuracy. Automatic tool change structure, rapid tool change, smooth movement. All parts of the machine tool and various measurement units all conform to the SI standard.
