Vertical machining center (CNC) refers to a machining center where the axis of the spindle is perpendicular to the worktable.It is a highly automated multi-function CNC machine tool with tool magazine and automatic tool changer.Mainly suitable for processing templated class、disc、mould and complex parts.
Vertical machining center can complete the processes of milling, boring, drilling, tapping and thread cutting, so it is necessary to achieve at least three-axis two-linkage. Generally, three-axis three-linkage can be realized, and some can perform five-axis and six-axis control.
However, the vertical column height of the vertical machining center is limited, and the processing range of the box-type workpiece is too small, resulting in its dynamic characteristics directly affecting the machining performance of the machine tool. Siemens' CNC system and drivers, and uses automatic servo optimization to solve the problem of small workpiece processing range. Its "excellent curved surface" function also enables the CNC system to maintain high-speed and high-precision processing status and improve processing efficiency.
Machining centers are usually classified according to the relative positions of the spindle and the table, and are divided into horizontal, vertical and universal machining centers.
Horizontal machining center: refers to a machining center with the spindle axis parallel to the worktable, and is mainly suitable for machining box parts.
Vertical machining center: refers to a machining center where the axis of the spindle is perpendicular to the worktable, and is mainly suitable for processing complex parts such as plates, discs, molds and small shells.
Universal machining center (also known as multi-axis linkage machining center): refers to a machining center that can control the linkage change through the angle between the machining spindle axis and the rotary axis of the table to complete the machining of complex space curved surfaces. It is suitable for the processing of impeller rotors, molds, cutting tools and other workpieces with complex spatial curved surfaces.
