The difference between a vertical machining center and a horizontal machining center
A vertical machining center refers to a machining center where the spindle is in a vertical state. Its structural form is mostly a fixed column, and the worktable is rectangular without indexing and rotation functions. It is suitable for machining disc, sleeve, and plate parts. A vertical machining center generally has three linear motion coordinate axes and can install a rotating table along the horizontal axis on the worktable, commonly known as a four-axis machining center in the industry. It is mostly used for machining spiral line parts. Vertical machining centers are easy to install, operate, observe machining conditions, debug programs, and have a wide range of applications. However, due to the height of the column and the limitations of the tool-changing device, it can't process parts that are too high. When machining cavities or concave surfaces, chips are not easily discharged, and in severe cases, they can damage the tool, destroy the already machined surface, and affect the smooth progress of machining. A horizontal machining center is a machining center with a horizontal spindle, usually equipped with an automatic indexing rotary worktable. It generally has 3-5 motion coordinates, commonly consisting of three linear and one rotary motion coordinate. After one clamping, the workpiece completes the machining of the other four surfaces except for the mounting and top. It is most suitable for machining box-type parts. Compared with vertical machining centers, horizontal machining centers have convenient chip removal and are beneficial for machining, but they have complex structures and higher prices.
