Machining Centers & Milling Machines

The term “machining center” describes almost any CNC milling and drilling machine that includes an automatic toolchanger and a table that clamps the workpiece in place. On a machining center, the tool rotates, but the work does not. The orientation of the spindle is the most fundamental defining characteristic of a machining center. Vertical machining centers generally favor precision while horizontal machining centers generally favor production—but these are loose generalizations, and plenty of machining centers break out of them. Another common machining center type is the five-axis machining center, which is able to pivot the tool and/or the part in order to mill and drill at various orientations.
