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.

It 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.
