The difference between CNC machining center and CNC milling machine

The cnc machining center is developed from a CNC milling machine, which is a CNC milling machine with tools. Friends in the field of CNC and mechanical processing are certainly not strangers. By installing tools for different purposes, the machining center can perform multiple processes continuously with one clamping. To put it bluntly, the machining center is smarter than the CNC milling machine and can automatically change tools.

There is no problem with this method of differentiation. But it is not particularly rigorous. The difference between the machining center and the CNC milling machine lies in the standards of product implementation.

The geometric accuracy, position accuracy and working accuracy of the machining center have strict international and domestic standards. For example, the ball screw and the spindle of the vmc850 machining center have high accuracy. Even if these equipments are not equipped with a tool magazine, we will classify it as a machining center machine. CNC milling machine can be divided into lifting table and bed type. The spindles of the lifting table CNC milling machine mostly rely on manual speed change, which can only meet the general milling processing. The execution standard is the general level accuracy standard of the national standard CNC milling machine. The structure of the bed type CNC milling machine is similar to the machining center machine. The spindle head moves up and down, and the spindle is infinitely variable. The execution standard is the national standard CNC milling machine precision grade accuracy standard. However, there is still a certain gap between the machining accuracy and the machining center.

In addition, the CNC milling machine has only three axes, which are mostly used for plane processing. The machining center can be four-axis or five-axis linkage, which can be applied to multi-axis linkage technology to complete the machining of complex curved surfaces. In the scope of use, the machining center is wider than the CNC milling machine.
