The first machining center was first developed by Carney-Trek in 1958. It adds an automatic tool changer on the basis of the CNC horizontal boring and milling machine, which realizes the centralized processing of multiple processes such as milling, drilling, boring, reaming, and tapping after the workpiece is clamped once. The machining center is a highly automated multifunctional CNC machine tool with a tool magazine and an automatic tool changer. After the workpiece is clamped on the machining center once, multiple processes can be completed on more than two surfaces, and there are multiple tool change or tool selection functions, which greatly improves the production efficiency.
Machining centers are divided into boring and 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.
