What are the characteristics of CNC milling machines
What are the characteristics of CNC milling machines? 1. Processing characteristics For processing parts that are frame-shaped planes or steps of unequal height, then the point-position---linear system CNC milling machine can be used. If the processing part is a curved surface contour, the two-coordinate linkage and three-coordinate linkage system should be selected according to the geometric shape of the surface. It is also possible to add a numerical control indexing head or numerical control rotary table based on the general numerical control milling machine according to the processing requirements of the parts. At this time, the system of the machine tool is a four-coordinate numerical control system, which can process spiral grooves and blade parts.

The composition of the machining center
The machining center has five elements: CNC system, detection device, drive device, machine tool transmission chain, servo motor, with tool magazine and automatic tool change device. It combines the functions of CNC milling machine, CNC boring machine, and CNC drilling machine. It has powerful functions. In recent years, there have been many turning machining centers, which can almost complete all the machining processes of revolving parts.
Specific types of machining centers
Classified by tool change form (1) Machining center with tool magazine manipulator The machining center tool change device is composed of a tool magazine and a manipulator level, and the tool change action is completed by the manipulator.
