A method for improving the working efficiency of lathes by CNC lathe manufacturers
When processing on CNC machine, the program is programmed according to the part drawing. The programming code and command pattern mostly conform to the ISO standard and the corresponding national standard. Then the program is input into the NC or CNC through the information carrier, and the numerical control system is based on the program content. Announced the order, on the one hand, the motor in the servo system controls the movement of the machine through the transmission equipment, and on the other hand, the other auxiliary movements of the machine tool, such as the spindle speed, steering selection, the start and stop of the cooling pump, etc. Work together to complete the processing content.
The information carrier is a punched paper tape, a punched card, a magnetic tape, a magnetic disk, etc., and is used to record the contents of the programming, and is sent to the numerical control device through a reading device such as an optical tape reader, a tape drive, and a disk drive.
CNC equipment is the core of CNC machinery, which is often referred to as NC (general numerical control equipment) or CNC (computer numerical control equipment). NC is a way of initial development of numerical control machinery. Most CNC machines now use CNC system. The function of the numerical control equipment is to withstand the processing information input by the input device. After decoding and processing, the corresponding command pulse is announced to the servo system, and the parts are processed.
The servo system is the fulfillment part of the numerical control machine and consists of an electric motor and a transmission device. The servo system is subjected to the command pulse signal from the numerical control device to control the displacement and speed of the movement of the machine tool (workbench or tool holder).
The machine body is mainly a mechanical part, and includes a main moving part, a feed moving part, and a supporting part. As far as numerical control mechanical parts are concerned, the mechanical parts are simpler than the general-purpose machine tools, but their technical specifications are higher than those of general-purpose machine tools.
