A vertical machining center refers to a machining center whose spindle axis is perpendicular to the workbench. It is mainly suitable for processing complex parts such as plates, discs, molds, and small shells. The vertical machining center can complete milling, boring, drilling, tapping, and thread cutting.

Vertical machining centers are at least three-axis and two linkages, and can generally realize three-axis and three linkages. Some can be controlled by five axes and six axes. The column height of the vertical machining center is limited, and the machining range of box workpieces should be reduced, which is the disadvantage of the vertical machining center. However, the vertical machining center is convenient for workpiece clamping and positioning; The movement track of the cutting tool is easy to observe, the debugging program is convenient to check and measure, and problems can be found in time to stop the machine for treatment or modification; The cooling condition is easy to establish, and the cutting fluid can reach the cutting tool and the machined surface directly; The three coordinate axes are consistent with the Cartesian coordinate system, which makes it intuitive and consistent with the perspective of the drawing. The chips are easy to be removed and dropped, to avoid scratching the machined surface. Compared with the corresponding horizontal machining center, it has the advantages of simple structure, small floor area, and low price.

Classification

• Classification according to guide rail

According to the form of each axis guide rail of the vertical machining center, it can be divided into hard rail and wire rail. The hard rail is suitable for heavy cutting, and the line rail movement is more sensitive.

• Classification by speed

The spindle speed of the vertical machining center is low-speed at 6000-15000rpm and high-speed above 18000rpm.

• Classification by structure

According to the bed structure of the vertical machining center, it can be divided into C type and gantry type.

• Vertical

A vertical machining center refers to a machining center with a vertical spindle. Its structural form is mostly a fixed column. The workbench is rectangular and has no indexing rotation function. It is suitable for machining disc, sleeve, and plate parts. It generally has three linear motion coordinate axes and can be installed with a rotary table rotating along the horizontal axis on the workbench to process spiral parts.

The vertical machining center has the advantages of convenient clamping, easy operation, easy observation of machining conditions, easy debugging program, and wide application. However, due to the limit of column height and tool changing device, parts too high cannot be processed. When processing the cavity or concave surface, the chip is not easy to be discharged. In serious cases, the tool will be damaged, the machined surface will be damaged, and the smooth processing will be affected.

• Horizontal

A horizontal machining center refers to a machining center with a horizontal spindle. It is usually equipped with a rotary worktable with automatic indexing. It generally has 3-5 motion coordinates. It is common to add three linear motion coordinates and one rotary motion coordinate. After the workpiece is clamped at one time, it completes the machining of the other four surfaces except for the mounting surface and the top surface. It is most suitable for adding box parts. Compared with the vertical machining center, the horizontal machining center is easy to remove chips during machining, which is beneficial to machining, but the structure is complex and the price is high.
