CNC(numerical control machine tool) is the abbreviation of Computer Numerical Control (Computer Numerical Control), is a kind of automatic machine tool controlled by program.

The control system can process logically the program with control code or other symbolic instructions, and decode it by computer, so that the machine tool can execute the prescribed action, and process the blank material into semi-finished finished valves or valve metal parts by cutting tools.

The traditional valve processing is the use of manual operation of ordinary machine tools, processing with hand shaking mechanical cutting valve, by the eye with calipers and other tools to measure the accuracy of the product. Imetllm valve production base has already used the computer digital-controlled machine tools for operations, CNC machine tools can be in accordance with the technical personnel in advance of the program of automatic processing of any products and parts directly. This is what we call "CNC machining". Numerical control machining is widely used in all mechanical processing and metal manufacturing fields, but also the development trend of metal valve mold processing and an important and necessary technical means.

"CNC" is an acronym for Computerized Numerical Control.

What is Numerical Control technology, Numerical Control technology, Numerical Control for short. It is a method to control machine tool motion and machining process by using digital information. The machine tool that implements processing control with numerical control technology, or the machine tool that is equipped with numerical control system is called numerical control (NC) machine tool. CNC system includes: CNC device, programmable controller, spindle driver and feed device and other parts. Numerical control machine tool is a highly integrated product of machine, electricity, fluid, gas and light. In order to control the machine tool, it is necessary to use geometric information to describe the relative motion between the tool and the workpiece and to use process information to describe some process parameters that the machine tool must have. For example: feed speed, spindle speed, spindle positive and negative rotation, tool change, coolant switch, etc. These information according to certain format form processing file (that is, the normal said the nc machining program) in the information carrier (such as disk, paper tape, tape, etc.), and then by the machine tool numerical control system to read (or directly through the numerical control system keyboard input, input) or by means of communication, through the decoding, to make the machine movement and machining parts. Modern CNC machine tool is a typical product of mechatronics, which is the technical basis of new generation of production technology and computer integrated manufacturing system. 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 intelligent and full-function general numerical control device with open structure of both hardware and software. Numerical control technology is the basis of machining automation and the core technology of numerical control machine tools. Its level is related to the national strategic position and reflects the level of the comprehensive strength of the country. It develops with the development of information technology, microelectronics technology, automation technology and detection technology. CNC machining center is a CNC machine tool with a tool storehouse and can automatically change the tool, the workpiece can be in a certain range for a variety of processing operations. The characteristics of the processing of parts in the machining center are: the processed parts after a clamping, CNC system can control the machine tool according to different processes automatically select and replace the tool; Automatically change the machine spindle speed, feed and tool relative to the workpiece movement track and other auxiliary functions, continuously on the workpiece processing surface automatically for drilling, shaving, reaming, boring, tapping, milling and other processes. Because the machining center can be centralized, automatic to complete a variety of procedures, to avoid the artificial operation error, reduce the workpiece clamping, measurement and machine 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 location of the spindle in space can be divided into vertical machining center and horizontal machining center. Horizontal machining center effectively solves the precise processing of large molds and the precise manufacturing of finished products.
