Vertical machining center refers to a machining center set perpendicular to the spindle axis and the workbench, mainly suitable for processing complex parts such as plates, discs, molds, and small shells. Vertical machining centers can complete processes such as milling, boring, drilling, threading, and thread cutting. A vertical machining center should have at least three axes and two linkage, and can generally achieve three axes and three linkage. Some can be controlled with five or six axes. Its specific classification is as follows:

Classification based on guide rails

According to the form of each axis guide rail of a vertical machining center, it can be divided into hard rails and line rails. Hard rails are suitable for heavy cutting, and line rail motion is more sensitive.

Classification based on speed

The spindle speed of the vertical machining center is 6000-15000rpm, which is a low-speed type, and above 18000rpm, which is a high-speed type.

Classification based on structure

According to the bed structure of vertical machining centers, they can be divided into C-type and gantry type.

The height of the vertical machining center column is limited, and the machining range for box type workpieces needs to be reduced, which is the disadvantage of vertical machining centers. But the vertical machining center is convenient for workpiece clamping and positioning; The movement trajectory of the cutting tool is easy to observe, the debugging program is convenient for inspection and measurement, and problems can be detected in a timely manner for shutdown or modification; Cooling conditions are easy to establish, and cutting fluid can directly reach the tool and machining surface; The three coordinate axes are in line with the Cartesian coordinate system, which feels intuitive and consistent with the perspective of the pattern. Chip removal and falling are easy to avoid scratching the processed surface. Compared with the corresponding horizontal machining center, it has a simple structure, a smaller footprint, and a lower price.
