CNC machining center is developed from CNC milling machine. The difference between the CNC milling machine and CNC machining center is that the machining center has the ability to actively exchange machining tools, through the tool magazine on the installation of different uses of the tool, can be in a clamping through the active tool changer change spindle machining tool, to achieve a variety of machining functions.

A CNC machining center has the following advantages:

1. CNC machining centers can be processed by conventional methods difficult to process the messy surface, and can even process some unobservable machining parts.

2. Processing quality and stability, high processing accuracy, high repeatability, accustomed to the processing requirements of the aircraft.

3. CNC machining centers reduce the number of fixtures in large quantities, and do not need messy fixtures to process parts with messy shapes. If you want to change the shape and scale of the parts, you only need to amend the parts processing program, suitable for new product development and restyling.

4. CNC machining centers in a variety of small batch production in the case of higher production power, can reduce the production preparation, machine tool adjustment and process inspection time, and because of the use of cutting volume and reduce the cutting time.

Second, the disadvantage of CNC machining is that the cost of machine tools and equipment is expensive, requiring a high level of repair personnel.

CNC machining center is a kind of tool magazine and can actively replace the tool, the workpiece can be in a certain range of a variety of processing operations of CNC machine tools.
