Speaking of the differences between machining centers and CNC milling machines, this is a common question. The machining center is developed from a CNC milling machine and is a CNC milling machine with a cutter. At this point, friends who have been engaged in the field of numerical control and machining will certainly not be unfamiliar. By installing tools for different purposes, the machining center can continuously perform a variety of processes with one clamping. To put it plainly, the machining center is better than the CNC milling machine in that it can automatically change tools.

There is nothing wrong with this distinction. However, it is not particularly rigorous. The difference between machining centers and CNC milling machines lies in the standards of product implementation.

The geometric accuracy, position accuracy and working accuracy of machining centers have strict international and domestic standards. For example, the ball screw and spindle of the vmc850 machining center have high accuracy. Even if these equipments are not equipped with a tool magazine, we also classify it as a machining center machine. CNC milling machine can be divided into lifting table and bed type. Most of the spindles of the lifting table-type CNC milling machine rely on manual speed change, which can only meet the general milling processing, and 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 that of a machining center machine. The spindle head moves up and down, and the spindle is continuously variable. The execution standard is the national standard CNC milling machine precision level 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, machining centers are more extensive than CNC milling machines.

When can a CNC milling machine be used? You need to understand the functions of a CNC milling machine.

The point control function is the main function of the CNC milling machine. The point control of the CNC milling machine is mainly used for the hole processing of the parts, such as center drilling positioning, drilling, reaming, countersinking, reaming and boring. Continuous control function Mills the plane and surface of the workpiece through linear interpolation, circular interpolation or complex curve interpolation motion of the CNC milling machine.

Canned cycle processing function, the application of canned cycle processing instructions can simplify the processing program and reduce the programming workload. NC milling machines are mainly for plane machining. If milling complex surfaces, a machining center with three or more axes is required.

In general, CNC machining machines are used for machining centers in terms of performance efficiency, machining types, and applications. Of course, the price is also a lot higher than that of CNC milling machines. When purchasing equipment, you must understand your processing requirements in detail and fully understand the characteristics of the equipment so as to avoid unnecessary waste of equipment.
