Understanding the basic structure and basic working principle of small CNC lathe is the basic guarantee for improving the fault analysis ability of CNC lathe. It is the evolution of lathe. Because the precision required is generally very high. Now many companies use CNC machine tools, which are more convenient to operate. If it is just operation, it is very simple, just a little learning or training will do.
When processing parts on CNC lathe, the operator must first design a set of processing plans according to the part drawings, and then write the part processing program. In the editing state (EDIT) of the lathe control device, the written processing program is input and stored in the memory of the CNC device. The CNC device of the CNC lathe decodes, stores, processes and calculates the information code, and then distributes the calculation results to the servo system of each coordinate of the machine tool in the form of digital signals. After the servo system of each coordinate of the machine tool receives the signal sent by the CNC device, it drives the moving parts of the machine tool through the transmission device through each servo system, so that the CNC lathe performs processing actions according to the predetermined speed, range and route, thereby processing parts that meet various requirements.
CNC lathe is a machine developed in modern times. It consists of four parts: information carrier, CNC equipment, servo system and machine tool body. Compared with ordinary lathes, CNC lathes have significantly improved their processing efficiency, and some workpieces that were difficult or impossible to process in the past can also be processed. It can be said that CNC lathes have brought many benefits to daily life.
When processing on CNC lathes, programs should be compiled according to part drawings. The programming codes and instruction formats mostly comply with ISO standards and corresponding national standards. Then the program is input into NC or CNC through the information carrier. The CNC system issues instructions according to the program content. On the one hand, the motor in the servo system controls the movement of the machine tool actuator through the transmission device, and on the other hand, it controls other auxiliary movements of the machine tool, such as spindle speed, steering selection, cooling pump start and stop, etc. The two aspects work together to complete the processing content.
The core of CNC equipment small CNC lathe is often called NC (general CNC equipment) or CNC (computer numerical control equipment). NC is a method in the early development of CNC lathes. Most of the current CNC lathes use CNC systems. The function of CNC equipment is to receive the processing information input by the reading device, and after decoding and calculation, issue the corresponding command pulse to the servo system to complete the parts processing. The machine tool body is mainly mechanical parts, including main moving parts, feed moving parts and supporting parts. For CNC lathe parts, the structure of mechanical parts is simpler than that of general machine tools, but its various technical indicators are higher than those of general machine tools.
