Vertical Machining Center
A vertical machining center refers to a machining center in which the axis of the spindle and the worktable are vertically arranged. The vertical machining center is mainly suitable for processing complex parts such as plates, discs, molds and small shells. The vertical machining center can complete the processes of milling, boring, drilling, tapping and thread cutting. The vertical machining center has at least three axes and two linkages, and generally three axes and three linkages can be realized. Some can carry out five-axis and six-axis control.
The height of the vertical machining center column is limited, and the processing range of box-type workpieces needs to be reduced, which is the shortcoming of the vertical machining center. However, the workpiece clamping and positioning of the vertical machining center are convenient; the movement track of the cutting tool is easy to query, the debugging program is easy to check and measure, and the problem can be found in time, and the shutdown processing or correction can be carried out; the cooling condition is easy to establish, and the cutting fluid can directly reach the tool and the processing surface; The three coordinate axes conform to the Cartesian coordinate system, which is intuitive and consistent with the perspective of the pattern, and the chips are easy to sweep and fall 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.
According to the characteristics of vertical machining center products, it can be divided into hard rail vertical machining center and line rail vertical machining center. The difference features are: the difference is defined according to the form of the guide rails of each axis of the vertical machining center. There are significant functional differences between the two in workpiece processing. The hard rail vertical machining center is suitable for heavy-duty cutting, and the linear rail vertical machining center has a fast displacement speed and more responsive processing movement.
