What Is The Difference Between CNC Machining Center And CNC Milling Machine

CNC machining centers are developed from CNC milling machines, which are CNC milling machines with cutting tools. By installing tools for different purposes, CNC machining centers can complete clamping at one time and continuously perform a variety of processes. To put it bluntly, CNC machining center is better than the CNC milling machine in that it can change tools automatically. There is no problem with this method of distinction. However, it is not particularly rigorous. The difference between CNC machining centers and CNC milling machines lies in the product implementation standards.

The geometric accuracy, position accuracy and working accuracy of CNC machining center have strict international and domestic standards. The ball screw and spindle of the CNC machining center have high precision. Even if these equipment are not equipped with a tool magazine, we also classify it as CNC machining centers. CNC milling machines can be divided into lifting table type and base type. The spindle of lifting table type CNC milling machine mostly depends on manual speed change, which can only meet the ordinary milling processing. The implementation standard is the national CNC milling machine ordinary grade accuracy standard. The structure of base type CNC milling machine is similar to that of CNC machining center. The spindle head moves up and down and the spindle changes speed steplessly. The implementation standard is the national CNC milling machine precision grade standard. In addition, CNC milling machine has only 3 axes, which is mostly used for plane machining. CNC machining centers can have 4-axis or 5 axis linkage, which can be applied to the multi axis linkage technology to complete the machining of complex surfaces. CNC machining centers are more widely used than CNC milling machines.
