Understanding the basic structure and working principle of turning-milling composite CNC machine tools is the basic guarantee for improving the failure analysis capabilities of CNC lathes. This is the development of lathes. Because the accuracy is generally very high. Many companies are now using CNC machine tools, so it is more convenient to operate. If it's just operation, it's very simple, just a little learning or training.
When machining parts on a CNC lathe, we must first design a set of processing plans based on the part drawing, and then write the part processing program. In the editing state of the lathe control device, the prepared processing program is input and stored in the memory of the numerical control device. Information coding is decoded, stored, processed and calculated by the numerical control device of the numerical control lathe, and the calculation result is distributed to the servo system of each coordinate system of the machine tool in the form of a digital signal. After the servo system of each coordinate system of the machine tool receives the signal from the numerical control device, it drives the moving parts of the machine tool through the transmission device through the servo system, so that the numerical control lathe can process parts according to the predetermined speed, range and path, and process parts that meet various requirements. .
CNC lathe is a kind of machine tool developed in modern times. It is composed of information carrier, numerical control equipment, servo system and machine tool body. Compared with ordinary lathes, the processing capacity of CNC lathes has been significantly improved, and some workpieces that were difficult or impossible to be processed in the past can also be processed. It can be said that CNC lathes have brought many benefits to daily life.
When processing on a CNC lathe, the program should be compiled according to the part drawing. The program code and instruction format basically comply with ISO standards and corresponding national standards. Then input the program into NC or CNC through the information carrier, and the CNC system issues instructions according to the program content. On the one hand, the motor in the servo system controls the movement of machine tool components through the transmission device. On the other hand, the program is controlled by the motor in the servo system. On the other hand, it controls other auxiliary movements of the machine tool, such as spindle speed, steering selection, start and stop. The cooling of the cooling pump is to complete the processing content with both parties.
Numerical control equipment is the core of small numerically controlled lathes, often called NC (General Numerical Control Equipment) or CNC (Computer Numerical Control Equipment). Numerical control is a way of early development of numerically controlled lathes. Now most numerically controlled lathes adopt numerical control systems. The function of the numerical control equipment is to receive the processing information input by the equipment, and after decoding and calculation, send the corresponding instruction pulse to the servo system to complete the part processing. The main body of the machine tool is mechanical parts, including main moving parts, feed moving parts and supporting parts. For the parts of CNC lathes, the structure of mechanical parts is simpler than that of ordinary machine tools, but the requirements for various technical indicators are higher than that of ordinary machine tools.
