The 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 disk, 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 is easy to install, operate, observe and debug, and widely used. However, due to the limit of column height and tool changing device, it is not allowed to process too high parts. When machining the cavity or concave surface, it is not easy to discharge the chips. In serious cases, it will damage the tool, damage the machined surface and affect the smooth processing.
Horizontal machining center refers to a machining center with a horizontal spindle, usually with an automatic indexing rotary table, which generally has 3~5 motion coordinates. It is common to have three linear motion coordinates plus one rotation motion coordinate. After the workpiece is clamped once, it completes the machining of the other four surfaces except the mounting surface and the top surface. It is suitable for adding box type parts. Compared with the vertical machining center, the horizontal machining center is easy to remove chips during machining, which is beneficial to machining, but its structure is complex and its price is high.
