Numerical control machine tool is a modern and developed machine. With the development of high technology, the application planning of high-precision and ultra precision forming grinders is becoming increasingly widespread. It consists of an information carrier, numerical control equipment, servo system, and machine tool body. Compared with ordinary lathes, its machining capacity has been significantly improved, and some workpieces that were difficult or impossible to machine in the past can also be machined. The production of specific grinding machines is increasingly accepted by users. Below, let's analyze the four core components of CNC machinery
Information carriers, including punched paper tape, punched cards, magnetic tapes, and disks, are used to record programming content and are transmitted to CNC equipment through reading devices such as optical paper tape readers, tape drives, and disk drives Numerical control equipment is the core of numerical control machinery, usually referred to as NC (universal numerical control equipment) or CNC (computer numerical control equipment). Numerical control is an early development method of numerical control machinery, and most of the current numerical control machinery adopts numerical control systems. The function of CNC equipment is to read in the machining information input by the device, decode and calculate it, and then announce the corresponding command pulses to the servo system to complete the part machining The servo system is the executing part of a CNC machine tool, consisting of motors and transmission equipment. The servo system receives command pulse signals from CNC equipment and controls the displacement and speed of machine tool execution components (worktable or tool holder) The main body of the machine tool is the mechanical part, including the main moving parts, feed moving parts, and support parts. As for CNC mechanical parts, the structure of mechanical parts is simpler than that of general machine tools, but their technical requirements are higher than those of general machine tools When machining on CNC machinery, the first step is to program according to the part drawing, and the programming code and instruction mode mostly comply with ISO and corresponding specifications. Then, the program is input into NC or CNC through an information carrier, and the NC system announces instructions based on the program content. The motor in the servo system controls the movement of the machine tool's executing components through transmission equipment, and also controls other auxiliary movements of the machine tool, such as spindle speed, steering selection, and start stop of the cooling pump
