Fully automatic CNC machine tool Automatic CNC lathe industry is now facing a serious problem, is the leading high-end CNC machine imports. From the relevant data of CNC machine tool imports, in November 2012, China's CNC machine tool imports overall showed a downward trend, but the import price has been rising, which can show that the import of high-end CNC machine tools continued to rise. Do not say the machine itself, CNC machine tool is the machine tool to achieve automation and intelligence of the main products, the level of its CNC system is an important indicator to determine the level of automatic CNC lathe. However, 90 percent of China's CNC systems are imported from abroad. Domestic CNC system, especially high-grade CNC system and foreign technology, whether it is machining accuracy, stability or reliability, the gap is still very obvious. From the domestic CNC machine tool industry as a whole, China's high-end CNC machine tool industry is the biggest short board, but also the biggest obstacle to industrial upgrading. In response to this situation, the state plans to implement the "high-grade CNC machine tools and basic manufacturing equipment" this major science and technology projects, including more than 10 projects. Due to the complex and huge CNC technology system, automatic CNC lathe CNC system is a high-tech electronic industry both software and hardware research and development content, requires a large capital and technical strength, not a family can support. Reckless investment in the future, unable to support, easy to cause human and financial losses, so the government's guidance is necessary. The organization of CNC system production, learning, research and so on, so on the functional components. Yield and output value rate of numerical control machine tool in our country from 11% in 2004 and 27% in 2013 to 34.6%, 54.7%, and the CNC numerical control machine tool production rates in the developed countries average of over 65%, the output value numerical control rate at about 80%, so the development of nc machine tools in China still has large potential, predicts 2020, high-grade numerical control machine tool equipment rate will reach 80%. At present, China's annual consumption of high-grade CNC machine tools in the number of about 50-60 thousand sets, the amount of about 6 billion yuan, of which imports accounted for about 85% of the total. In the future, China's CNC machine tool industry has a good development potential and a large space for import substitution.

Fully automatic machine Automatic hydraulic lathe in the hydraulic machine industry, the use of frequency converter scale. However, Japan's yaskawa, Fuji, mitsubishi and Taiwan's delta and other brands occupy a larger market share. Although also have a few homebuilt brand inverter is chosen by machine tool manufacturing enterprise, but in grinder, forging press machine tool wait for the domain with taller to inverter industry function entreat, as usual it is foreign brand is in the majority, be like mitsubishi, Fuji, German Siemens, delta wait for a brand to be in advantage as usual. According to 2008, 2009 machine tool sales data flash, universal machine tools, especially complex function of the lathe inventory situation is serious, and complex machine tools, large heavy products market is better. These machine tools processing scale is wide, the implementation of machine tools components have strange activity speed, the inverter function also put forward a higher request, domestic inverter manufacturers should seize the opportunity to cultivate the machine tool market. With the development of frequency converter technology, its application in machine tool industry is developing continuously. The opening trend of the inverter for automatic hydraulic lathe is shown as follows: One is high performance. At present, all inverters require vector control methods, and there are a few different levels of control structure and algorithm. It is worth noting that speed sensorless vector control (SVC) is opening faster in recent years, because SVC can plead low interest, high function of the disposal plan, formerly became the dream of universal inverter specifications and open direction. Second, easy to control from time to time forward. The user's demand for frequency converters is gradually transformed into field devices, and additional Settings are added to the software, so as to simplify the debugging process after the user's operation. Third, the function of modular and intelligent demand gradually rising. It is understood that a machine tool with the number of frequency converter some up to 4-5. This is enough to foresee the market potential of machine tool inverters.

Automatic CNC lathe is a high technical content of electromechanical integration of the machine tool, the user to buy a CNC machine tool, whether the correct safe boot, commissioning is a key step. Automatic CNC lathe startup debugging: CNC machine tool is a high technology of electromechanical integration of the machine tool, the user to buy a CNC machine tool, whether the correct and safe startup, debugging is a key step. The correctness of this step in a large program determines whether this CNC machine tool can play a normal economic efficiency and its own life, which is of great importance to the production plant and user plant CNC machine tool. CNC machine starting, debugging should be carried out according to the following steps. 1. Appearance inspection of fully automatic CNC lathe before power on: (1) machine tools electrical check open the electric cabinet, check relay, contactor, fuse, servo motor, speed control unit socket, spindle motor speed control unit such as presence of loose socket, such as loose should return to normal state, a locking mechanism of connectors must lock, a connecting box machine must check the adapter socket on the box, loose connection with and without, a locking mechanism must be locked. (2) CNC electrical box inspection open the CNC electrical box door, check all kinds of interface socket, servo motor feedback line socket, spindle pulse generator socket, hand pulse generator socket, CRT socket, etc. Check the setting of short-circuit terminals on each printed circuit board according to the instructions, and be sure to comply with the state set by the machine tool manufacturer. If there is something wrong, it should be reset. In general, there is no need to reset. (3) check wiring quality. Check all wiring terminals. Including the strong and weak electricity in the assembly of the machine tool factory to connect the terminal and the power line of the motor wiring terminal, each terminal should be used to tighten the screw once, until the screw can not move, the motor socket must be tightened. (4) solenoid valve inspection: all solenoid valves should be pushed several times by hand to prevent improper operation caused by power failure for a long time. If any abnormality is found, it should be recorded to confirm repair or replacement after power on. (5) limit switch inspection check whether all limit switch actions are flexible and fixed, and deal with those found to be defective or not fixed. (6) check the buttons and switches on the operation panel. Check the wiring of all buttons, switches and indicator lights on the operation panel. If there is any error, it shall be dealt with immediately. (7) ground check request has the good earth, measuring machine ground, Ω grounding resistance is not greater than 1. (8) check the phase sequence of the input power supply with the phase sequence table, and confirm that the phase sequence of the input power supply is absolutely consistent with the phase sequence of the calibrated power supply in various places on the machine tool. For equipment with secondary wiring, such as power transformers, the consistency of phase sequence of secondary wiring must be confirmed. You want to make sure that the phase sequence is absolutely correct. The power supply voltage should be measured and recorded. 2. Switch on the total voltage of CNC machine tool: (1) switch on the general power of the machine tool, check whether the steering of the CNC electric box, the cooling fan of the spindle motor, the cooling fan of the machine tool electrical box is correct, whether the oil mark indication of lubrication, hydraulic pressure and other places and whether the machine tool lighting is normal, whether there is any damage to the fuse, if there is any abnormality, the power should be cut off immediately for maintenance, no abnormality can continue. (2) measure and record the voltage of each part of the strong current, especially the primary voltage of the power transformer for CNC and servo units. (3) observe whether there is any oil leakage, especially the hydraulic cylinder and solenoid valve at the position of the turret, clamping, the shift of the spindle and the clamping of the chuck. In case of oil leakage, repair or replace immediately.

Fully automatic CNC machine parse fully automatic CNC machine machining precision of high precision nc machine tools in general can be up to 0.05 0.1 MM, nc machine tools is according to the form of digital signal control, numerical control device every output a pulse signal, the machine moving parts move a pulse equivalent (0.001 MM), and machine tool feed drive chain of the reverse clearance and screw pitch error of the mean by the nc device march compensation, therefore, the numerical control machine tool positioning accuracy is higher.

 The wide application of automatic CNC instrument lathe greatly reduces the requirements of workers, improve production efficiency, but once the machine tool failure often seriously affect the production schedule, to bring great losses to the enterprise. When removing a circuit board from a fully automatic CNC lathe, pay attention to the position of the corresponding cable connected to the digital record, for a fixed installation of the circuit board, should also provide before and after, remove the corresponding compression parts and screws. The parts and screws should be placed in a special box so that they will not be lost. After assembly, all the things in the box will be used, or the assembly will be incomplete. Most PCB solder layer brushes, so the measurement should find the corresponding solder spot as the test point, do not remove the solder strip and some of the brush insulation layer, only in the solder spot blade scratch insulation layer. Automatic CNC instrument lathes should not cut off the printed circuit at will. Some maintenance personnel have certain experience in home appliance repair, used to break line to check, but most of the printed circuit board nc equipment of double metal orifice or multi-layer circuit boards, printed circuit board thin, dense, once it is not easy to cut the welding, and tangent easy cut in addition, some point, adjacent line, cut a line, can't make it and need to cut off the line output work of a few lines at the same time. Measure the resistance between the closed power lines. The measured resistance should be red. The black watch pen should be measured twice interchangeably. The soldering iron should be easily placed in front away from the repair circuit board. The soldering tips should be properly trimmed to fit the welding of integrated circuits and other components to avoid welding bumps. Components should not be replaced by feel. Some maintenance personnel in the absence of a component of the fault element, just feel bad, should be replaced immediately, so the misjudgment rate is higher, removed parts of the artificial damage rate is higher.
