The industry is currently localizing mid-to-high-end products. For a long time, domestic CNC machine tools have faced the challenge of expanding low-grade products rapidly, making slow progress in mid-grade products, and heavily relying on imports for high-grade products. Especially for key equipment needed in national projects, we mainly rely on imports, and the technology is controlled by others. The industry needs to undergo a gradual "quantitative change", as it is currently in the process of localizing mid-to-high-end products. However, the localization of mid-to-high-end CNC machine tools in China's CNC machine tool industry won't happen soon.   The market size is expected to drop by nearly 25% in 2020. From 2017 to 2019, my country's CNC machine tool industry experienced significant fluctuations in scale. In 2018, the industry reached a scale of 334.7 billion yuan, showing a year-on-year growth rate of 10.50%, which was slower than the growth rate in 2017. In 2019, the industry's scale decreased to 327 billion yuan, indicating a year-on-year decrease of 2.30%. This decline can be attributed to the adjustment and upgrading of the overall demand structure in the machine tool industry, as well as a slowdown in downstream fields. Due to the impact of the epidemic in 2020, China's CNC machine tool industry experienced a significant decline, reaching 247.3 billion yuan, a year-on-year decrease of 24.37%.   The highest number of companies involved in the abrasive industry. According to statistics from the National Bureau of Statistics and China Machine Tool Association, the machine tool market in 2019 witnessed fluctuations and a contraction in total demand, as well as adjustments and upgrades in demand structure. With these changes, the industry's structure and balance were disrupted. During this adjustment and development process, industry enterprises made continuous efforts to adapt to the drastic market changes. Some enterprises focused on their core business, deeply understanding market demands, and enhancing their adaptability. However, many companies faced severe operating difficulties, significant losses, funding shortages, and some even had to undergo reorganization or halt production. As a result, the industry experienced a major differentiation in its overall landscape. According to data from the China Machine Tool Association, as of December 2020, the composition of large-scale enterprises in China's machine tool industry is as follows: a total of 5,720 enterprises, divided into eight sub-industries: 833 metal cutting machine tools (accounting for 14.56%), 529 metal forming machine tools (9.25%), 747 measuring tools and instruments (13.06%), 2025 abrasives (35.4%), 356 machine tool functional parts and accessories (6.22%), 467 foundry machinery (8.16%), 127 wood and bamboo processing machinery (2.22%), and 636 other metal processing machinery (11.12%).   Automobiles are the biggest consumers of CNC airports. In terms of downstream consumption in the CNC machine tool industry, automobiles account for about 40% of the demand, making it the primary consumer. Aerospace follows with around 17% of the demand, while molds and construction machinery rank third in terms of CNC machinery. The fourth consumer sector represents approximately 13% and 10% of the demand, respectively. The market is expected to exceed 540 billion yuan by 2026. Looking at the market sales prospects, the main demand areas for CNC machine tools in China will undergo an adjustment period from 2021 to 2026. This adjustment will impact CNC machine tool sales for a certain period. However, after this downstream adjustment period, the demand for CNC machine tools will significantly increase, leading to accelerated sales growth. Although the epidemic has temporarily decreased the demand for machine tools in the downstream market in 2020, the long-term outlook is positive. Thanks to the convenience of CNC machine tools, the demand will rebound in 2021 and surpass 540 billion yuan.

CNC machine tools are highly efficient automated machines and their place in production is becoming increasingly important. Therefore, the troubleshooting and daily maintenance of equipment is very important, but most of the failures of CNC machine tools are in the form of integrated failures, so the maintenance is more difficult. Combined with the mechanism of CNC machine tools, we have summarized the four main methods, namely: look, smell& hear, ask and touch.   I. Look To find the cause of the fault through the human hand, eye and other sensory organs, which is also the most simple and direct method. When the machine tool failure, the first thing you need to understand is the phenomenon of failure and the causes and processes. If the fault can be reappeared, the process of the fault should be observed and the most basic situation should be mastered. At the same time, observe whether there is mechanical damage; and whether there are burn marks, whether the resistance and conductors have been discoloured; whether there are any abnormalities in the running and sealing parts, such as splashes, shedding, spills, oil, smoke, sparks, etc.; whether the circuit breakers, relays, etc. tripped, whether the fuse is melted; whether the machine power supply is out of phase, whether the three phases are seriously unbalanced, whether the machine voltage is normal; whether there are parts on the electrical components are off, broken wires, jammed, loose joints, etc.; whether the switch is suitable; whether the operator's processing procedures are correct, etc.     2. Smell& Hear Identify whether there is an odour. When the machine tool moving parts have violent friction, the electrical insulation will burn, while the oil, smoke, gas and insulation materials will produce a burnt smell; the machine will produce ozone smell when discharged, you will also hear the discharge sound.   3. Ask Ask what happens when a machine tool breaks down. When machining, it is advisable to have strict management measures in place so that operators can make detailed notes in the event of a breakdown. This can avoid the occurrence of faults when maintenance personnel are not around and can accurately reflect the specific circumstances of the fault. When a fault occurs in a CNC machine tool, the first thing to do is to stop the machine and protect the site, the operator to record the fault in as much detail as possible, where the important information is to be observed and recorded in detail. For example: when the fault occurs, the phenomenon of the fault occurs in the part of the machine as well as when the fault occurs in the state of the machine and the control system. If the fault occurs in the automatic machining mode, the machining program number, the program segment number where the fault occurred and the tool number used for machining should be recorded. In the event of a fault such as poor machining accuracy or excessive contour error, the number of the workpiece being machined should be recorded and the non-conforming workpiece retained for specific analysis. In the event of a fault, if the system has an alarm display, the alarm display and alarm code of the system should be recorded. If the fault occurs when machining a part, the probability of the fault occurring when machining a similar part should be recorded.     4. Touch Diagnosis and repair based on the phenomenon of failure; this step is also the most important one in the maintenance of CNC machine tools. Which can be divided into the following specific steps:   4.1 System parameters check Nowadays, the operating system of CNC machine tools is becoming more and more self-diagnostic, and most of the faults of CNC machine tools can be diagnosed. When a fault occurs in the CNC machine tool, sometimes an alarm message will be displayed on the monitor; sometimes the alarm device on the CNC unit, PLC unit and drive unit, such as the alarm light will flash, beep, etc. In this case, the first thing to do is to check the maintenance manual and check the corresponding parameter settings. Missing or incorrectly set system parameters can cause changes or failures in machine performance. For example, in the FANUC system machine tool automatic processing, the machine tool holder stops moving and the screen shows 500, 501 alarm, check the parameter manual to know the corresponding parameters for the storage travel limit positive and negative limit value exceeded, then the machine can be changed to manual state to adjust the tool holder to the correct travel range and correct the parameters, the alarm can be relieved.   4.2 Reset machine tool During processing, the system alarm caused by instantaneous fault can be cleared by hardware reset or turning on and off the system power supply in turn. In case of system confusion caused by power failure, unplugging and plugging of circuit board or undervoltage of battery in the working storage area of the system, the system must be initialized and cleared. Before clearing, pay attention to copy and record important data. If the fault still cannot be eliminated after initialization, carry out hardware diagnosis.   4.3 Diagnosis by measurement Measurement method is the basic method to diagnose equipment failure, we can use multimeter, oscilloscope, logic tester and other instruments to measure the electronic circuit. For example, to determine the phase sequence of the three-phase power supply of the CNC system, you can use the phase sequence meter. That is, connect the three-phase power supply line to the phase sequence meter, and when the phase sequence is correct, the phase sequence meter rotates in a clockwise direction, and vice versa. You can also use a dual-channel oscilloscope to measure, if the phase sequence is correct, the waveforms of each two phases differ by 120° in phase.   4.4 Principal analysis method   When other maintenance methods are difficult to solve the fault, you can check step by step from the working principle of the machine tool. For example, we once encountered the phenomenon of disordered teeth when machining threads on a machine tool using FANUC 0itd system. According to the basic principle of position control of NC system, it can be basically determined that the fault is on the rotary encoder, and it is likely that the feedback signal is lost. In this way, once the NC device gives the command position of feed rate, the actual position fed back will always be incorrect, and the position error cannot be eliminated, resulting in problems in thread interpolation. When the pulse encoder was removed for inspection, it was found that the filament in the encoder was broken, resulting in no feedback input signal, which was consistent with the phenomenon of principle analysis. After replacing the encoder, the fault was eliminated.   4.5 Component exchange method For some faults involving the control system, sometimes it is not easy to confirm which part is the problem, in the case of ensuring that there is no further damage, you can take the suspected faulty parts or components with the same spare parts or the same parts or components on the same type of machine tool or on other parts of this machine tool to replace them to determine whether a fault has occurred. If the fault is lifted after replacing the device, it can be determined that the device is damaged causing the fault; if the fault remains, the device is proven to be intact and can be tested by other methods.   These four methods are not only applicable to the maintenance of CNC machine tool faults, but also to other types of mechanical equipment faults.
