The first machining center was first developed by the American Carney-Trek Company in 1958. It adds an automatic tool changing device on the basis of the CNC horizontal boring and milling machine, thus realizing the centralized processing of various processes such as milling, drilling, boring, reaming and tapping after the workpiece is clamped once. The machining center is a highly automated multi-function CNC machine tool with a tool magazine and an automatic tool changer. After the workpiece is clamped once on the machining center, it can complete various processes for more than two surfaces, and has a variety of tool changing or tool selection functions, which greatly improves the production efficiency.
Machining centers are divided into two categories: boring, milling and turning according to their processing procedures, and can be divided into three-axis, four-axis and five-axis machining centers according to the number of control axes.
