Understanding the basic structure and working principle of small CNC lathes is the basic guarantee for improving the failure analysis capabilities of CNC lathes. This is the development of lathes. Because the required accuracy is usually very high. Now many companies are using CNC machine tools, which is more convenient to operate. If it's just surgery, it's very simple. Just learn or train a little.
When machining parts on a CNC lathe, the operator 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 machine tool control device, input the prepared processing program and store it in the memory of the numerical control device. After the information encoding is decoded, stored, processed and calculated by the numerical control device of the numerical control lathe, 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 of the numerical control device, it drives the moving parts of the machine tool through the transmission device of each servo system, so that the numerical control lathe can perform processing actions in accordance with the predetermined speed, range and route, so as to process the machine to meet various requirements. Kind of required parts.
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 is 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. Most of the program codes and instruction modes conform to ISO standards and corresponding national standards. Then the program is input into the numerical control or numerical control system through the information carrier, and the numerical control system issues instructions according to the content of the program. On the one hand, the motor in the servo system controls the movement of the performance parts of the machine tool through the transmission device. On the other hand, the motor in the servo system controls the movement of the performance parts of the machine tool on the one hand, and it controls other auxiliary movements of the machine tool, such as the spindle. Rotation speed, steering selection, cooling pump start and stop, etc., on the other hand, cooperate with each other to complete the processing content.
The core of small CNC lathes is usually called NC (General Numerical Control Equipment) or CNC (Computer Numerical Control Equipment). NC is a way of early development of CNC lathes. At present, most CNC lathes use CNC systems. The function of the numerical control equipment is to receive the processing information input by the read-in equipment, and send corresponding instruction pulses to the servo system after decoding and processing calculation to complete the part processing. The body is mainly mechanical parts, including main moving parts, feed moving parts and supporting parts. In terms of CNC lathe components, the structure of mechanical components is simpler than that of ordinary machine tools, but its technical requirements are higher than that of ordinary machine tools.
