The development trend of modern CNC machine tools


The development trend of modern CNC machine tools is high speed, high precision, high reliability, multi-function, complex, intelligent and open structure.  The main development trend is to develop the software and hardware with open structure intelligent full function general CNC device.  Numerical control technology is the basis of machining automation, is the core technology of numerical control machine tool, its level is related to the national strategic position and reflect the level of national comprehensive strength.  It develops with the development of information technology, microelectronics technology, automation technology and detection technology.  CNC machining center is a kind of CNC machine tool with a knife library and can automatically change the tool, the workpiece can be in a certain range for a variety of processing operations.  Machining parts in the machining center is characterized by: processed parts after a clamping, CNC system can control the machine tool according to different processes to automatically select and replace the tool;  The machine can automatically change the spindle speed, feed rate of the machine tool and the movement path of the tool relative to the workpiece and other auxiliary functions, and can continuously process drilling, countersink, reaming, boring, tapping thread, milling and other processes on each machining surface of the workpiece.  Because the processing center can be centralized, automatic to complete a variety of processes, to avoid the artificial operation error, reduce the workpiece clamping, measuring and machine tool adjustment time and workpiece turnover, handling and storage time, greatly improve the processing efficiency and processing accuracy, so it has good economic benefits.  Machining center according to the position of the spindle in space can be divided into vertical machining center and horizontal machining center.
