What is the difference between a CNC machining center and a CNC milling machine?

​​
The CNC milling machine has only three axes, and the CNC machining center can be four-axis or five-axis linkage. Generally, the CNC milling machine has three coordinates, namely X, Y, Z, plus a spindle. The machining center mainly refers to the machine tool with more than four coordinates. The CNC machining center can process more complex shapes than ordinary CNC milling machines.
​
The CNC machining center has an additional tool magazine and tool changing system. The CNC milling machine does not have a tool magazine, and the tool change is performed manually during the machining process. CNC milling machines are generally used to mill relatively simple surfaces, and can also mill relatively shallow holes. The machining center itself has a tool magazine, and the tool is automatically changed by the manipulator. The CNC milling machine is equipped with a tool magazine to become a CNC machining center. A tool magazine can hold a lot of knives, depending on the types of workpieces actually processed, such as face milling cutters, end milling cutters, keyway milling cutters, ball cutters, boring cutters, thread cutters, etc., with the function of automatic tool exchange. Install tools for different purposes in the tool magazine. It can change the processing tools on the spindle through the automatic tool changer in one clamping, and realize various processing functions such as drilling, boring, reaming, tapping, and grooving, which is convenient for parts processing!
​
In general, the CNC machining center is a CNC machine tool with a tool magazine and an automatic tool changer. It combines the functions of a CNC milling machine, a CNC boring machine, and a CNC drilling machine with powerful functions.
