CNC machine tool structure

CNCl machine tool is a kind of a program control system of automatic machine tools.CNC machine tool main components are: program compiled and carrier, input devices, cnc devices, driving devices and position detection device, auxiliary control device, numerical control machine tool machine tool ontology needs instructions according to the numerical control system, automatically to the spindle speed, feed rate, cutting tool trajectory and other machine auxiliary functions (such as automatic tool change and automatic cooling, etc.). It must use servo feed system to replace the ordinary machine tool feed system, and can automatically by the spindle speed regulation system to realize the spindle speed. Therefore, on the mechanical structure, the CNC machine tool spindle box and feed gearboxes results are generally very simple; The number of gear, shaft parts, bearing greatly reduced; Can be connected directly to the main shaft of the motor and ball screw, no gear. In the use of linear motor, the occasion of motorized spindle, can even without screw, spindle box. In addition, because most of the CNC machine tool can be through the numerical control system with auxiliary motion of the auxiliary function to control (M), so commonly used action button is also less than ordinary machine tool, operation more convenient, more simple.
