CNC numerical control machine tool it is digital program control is realized by using computer technology

'CNC' is an English Computerized Numerical Control ( Computer digital control) The abbreviations. CNC application of traditional machining is done with manual operation general machine tools, processing with hand moving machine tool cutting metal, rely on the eyes with a caliper tool such as the precision of the measurement products. Modern industrial homework already using computer digital control machine tool, CNC machine tools can be programmed in advance in accordance with the technical personnel program automatically to any directly processed products and parts. This is what we say 'nc'.

car milling compound CNC machine tool manufacturers of nc machining is widely used in all mechanical processing of any field, but also the development trend of mould processing and important and necessary technical means. Computer digital control, this technique by computer according to beforehand control storage procedure to perform the trajectory and the operation of the peripheral equipment of temporal logic control function.

due to using computer instead use of hardware logic circuit of the numerical control device, the input operation instructions of storage, processing, the realization of the arithmetic and logic control function, all can be done through computer software, processing of micro instruction transmitted to the servo drive or hydraulic driven motor actuators driven equipment operation. Nc machine tool is programmed according to the prior processing program, automatically to be processing parts processing.

we put the parts of the processing craft route, process parameters and tool trajectory, displacement, cutting parameters ( The spindle revolutions, feeding, back turning, etc. ) And the auxiliary function ( Tool change, spindle forward, reverse, cutting fluid, etc. ) , according to the regulations of the nc machine tool of instruction code and program format write into the processing program list, then this program list the contents of the records in the control medium ( Such as punched tape, tape, disk, magnetic bubble memory) And then input to the numerical control machine tool numerical control device, thereby command machine parts. CNC machine tools the medium made from the analysis of the part drawing to control all the process is called numerical control program.

CNC machine tools and common machine tool processing parts of the difference between nc machine tools is according to the program automatically machining parts, while the common machine tool to operate by the people, we just change control machine action program can achieve the purpose of processing different parts. Therefore, nc machine tools is particularly suited to small batch processing complicated shape and high accuracy requirements parts because of nc machine tools should be in accordance with the procedures for processing parts, programming good program, input to the numerical control device to direct the work of the machine. The input of the program is by controlling the media.
