Horizontal machining center refers to the machining center with horizontal spindle, usually with automatic indexing rotary table, it generally has 3-5 motion coordinates, the common is three linear motion coordinates plus a rotary motion coordinates, the workpiece in a card, complete the processing of the other four surfaces except the installation surface and 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, which is beneficial to machining, but the structure is complex and the price is high.
Vertical machining center refers to the machining center whose main shaft is vertical. Its structure is mostly fixed column. The worktable is rectangular and has no indexing rotation function. It is suitable for machining plate, sleeve and plate parts. It generally has three linear motion coordinate axes, and can install a rotary table rotating along the horizontal axis on the worktable to process spiral parts.
The vertical machining center is easy to install, operate, observe and debug. However, limited by the height of the column and the tool changing device, it is not possible to process too high parts. When machining the cavity or concave surface, the chip is not easy to discharge. In serious cases, the tool will be damaged, the machined surface will be damaged, and the smooth processing will be affected.
