Vertical machining center is a highly automatic multi-function CNC machine tool with tool magazine and automatic tool changing device. The two common types are as follows:

Vertical: refers to the spindle in a vertical state of the machining center. Its structure is mainly fixed column. The worktable is rectangular and has no indexing and rotation functions. It is suitable for handling discs, sleeves and plates. It usually has three linear motion coordinates. Axis and rotating table rotating along horizontal axis can be installed on the table to process spiral parts.

Vertical machining center is easy to install, easy to operate, easy to observe the processing, easy to debug program, and widely used. However, due to the height limitation of column and tool changer, too high parts cannot be processed. When machining cavity or concave contour, the chip is not easy to discharge. In severe cases, the tool will be damaged, the machined surface will be damaged, and smooth machining will be affected.

Horizontal: horizontal machining center is a machining center with horizontal spindle. It usually has an automatic indexing turntable. It usually has three to five motion coordinates. The common one is three linear motion coordinates plus one rotational motion. Coordinate, after one-time installation of the workpiece, complete the processing of the other four surfaces except the installation surface and the top surface. Best for adding box parts. Compared with the vertical machining center, the horizontal machining center is easy to remove chips in the process of machining, which is beneficial to machining, but the structure is complex. The price is high.
