The machine tool industry is the foundation of the manufacturing industry and the cornerstone of China's industrial development. But the industry is now filled with a lot of unrealistic remarks. Many machine workers who claim to be senior in the industry jumped out and used all kinds of misleading comments to make people sensational. These remarks are not empirical, but they are extremely confusing, such as imported machine tools that are myths. In the mouth of these "senior people", all domestically produced machine tools are not as good as foreign equipment. Chinese machine tools have poor steelmaking technology, poor heat treatment technology, and poor key components. Even if the Chinese assemble the world's number one machine tool, no one will buy it.

The statement that "the goods are not as good as people" is comparable to the savage beasts. In many hearts of people who don’t know the truth, the idea that "domestic machine tools are far less than imported machine tools" has been formed. In fact, it is not all. To give a simple example, it has been rumored that the five-axis linkage CNC system is sold to China by foreigners. If there is no foreigner's five-axis technology, China will never create a machine tool. But in fact, domestic Dalian Guangyang, Shanghai Yanyike, Shanghai Tuowei, Shenzhen Haide League, Wuhan Huazhong, Guangzhou Guangshu, Shenyang Feiyang, Shenyang Blue Sky, Shaanxi Huatuo and other enterprises have commercialized five-axis CNC system. Among them, many systems have withstood the severe test of the market. The five-axis system of Beijing Jingdiao has also entered a mature stage, all for personal use, and is not for sale.

At present, some brands of domestic machine tools are not lost to imported machine tools in terms of processing efficiency and machining accuracy. In the low-end machine tool market, apart from the ability to innovate and design, the same positioning of machine tools, foreign and China are almost at the same level. In terms of price, domestic machine tools have great advantages.

In the eyes of some Chinese people, foreign machine tools have fewer failures, and domestic machine tools have many failures. But is this true? Why is there such a situation?

Imported machine tools are generally used as core equipment by users, only for precision machining processes, and at the same time bear the responsibility of the company's facade. The daily enjoyment is also very good: living in a constant temperature room ensures that the machine tool is not affected by the thermal deformation of the temperature rise, and the surrounding is dug. The anti-vibration ditch prevents vibration waves from entering other equipment. The operator is the best control master in the company, equipped with dynamic balancing fixtures and tools, using the best lubricating oil and cutting fluid, and arranging the best grade. Maintenance level.

The domestic machine tool is "after the mother to raise", the most tired, the most bitter, the most dirty work, the treatment is the worst treatment. "Air conditioner? Don't tease, this machine tool is worth using a constant temperature environment?" It is also necessary for the horse to run fast, but does not want to graze the horse, which is the logic used by domestic machine tools. Most domestically produced machine tools are in a chaotic environment, accessories and tools can be used on a daily basis, perfunctory things, new employees, first arranged to practice on domestic machine tools, frequent large knife overloading. Dirty environment, lack of maintenance, overload operation, and improper use are the four main reasons for the rise in the failure rate of domestic machine tools.

Under such an environment comparison, domestic machine tools obviously have no advantage. To put it bluntly, domestic machine tools are based on the worst use environment. Looking at those imported machine tools that are pampered, there are also frequent accidents. We should not "seal" all foreign imported machine tools, but look down on the machine tools produced by domestic companies. Let's take a look at the side of the imported machine tool from the real news report.

Shaoxing imported CNC machine tools have a safety hazard with a failure rate of 19% within one year.

In recent years, many companies in Keqiao have accelerated the pace of “machine substitution”, and imported CNC machine tools have become the first choice for upgrading enterprises. However, what is surprising is that many imported CNC machine tools are more or less problematic. According to statistics, from 2015 to the end of July this year, Shaoxing Inspection and Quarantine Bureau completed a total of 110 batches of imported machine tools, the country of origin or region is mainly Taiwan, South Korea, Japan, etc., of which 21 batches failed, the failure rate was 19%. .

According to analysis, the main reasons for the failure of these CNC machine tools include no Chinese description, no Chinese warning sign, or the electronic control box protection level is not qualified. In particular, the quality and safety of CNC machine tools imported from South Korea is the most prominent. In the 16 batches of imported CNC machine tools examined, 14 batches were unqualified, and the batch failure rate was as high as 88%. (Source: Shaoxing Inspection and Quarantine Bureau)

Zhangzhou imported equipment "full physical examination" 8 months to recover losses of more than 4 million US dollars

On September 18th, Zhejiang Kaishan Group imported a number of CNC screw rotor milling machines from the UK. At the time of unpacking inspection, the staff of the Zhangzhou Inspection and Quarantine Bureau found that the number of arrival equipment was different from that of the British exporters. The company recovered the economic loss of 220,000 euros in time.

After discovering the problem, the inspector immediately contacted the British side to confirm the situation, and coordinated the import and export parties to sign the "Reissue of Goods Agreement", issued a customs inspection certificate, used for the customs clearance of the enterprise replacement equipment, to avoid the second tariff. . “Because of proper handling, the current replacement equipment has successfully arrived at the enterprise and entered the installation and commissioning phase.” The person in charge of Zhejiang Kaishan Group said.

It is reported that from January to August this year, Zhangzhou imported a total of 149 batches of mechanical and electrical equipment, with a value of 10.87 million US dollars, and 12 batches of unqualified products, with a value of 4.04 million US dollars. The batch unqualified detection rate was 8.1%. The unqualified detection rate was as high as 37.2%, which saved the company more than 4 million US dollars in economic losses. “Unqualified products mainly include lathes, CNC machine tools, X-ray applications and other products.” Ye Meiyan, Director of Inspection and Supervision Department of Zhangzhou Inspection and Quarantine Bureau introduced.

Henan Xinxiang imported machine tools are not "normal" work for half a year. Is this going to strike?

In 2014 (the time is a long time, but the incident has been dragged on to the present, it is also suffering this company), Henan Xinxiang Guanghong Machinery Equipment Co., Ltd. and Beijing Delite Trading Co., Ltd. (hereinafter referred to as Beijing Delite), Hyundai Financial Leasing Co., Ltd. (hereinafter referred to as Hyundai Finance) signed a supply contract and a finance lease contract, and purchased 2 CNC machine tools of the F400 model and 2 CNC machine tools of the F500/50 model number F650/50. The CNC machine tool has a total of 5 CNC machine tools for enterprises to expand production and improve product quality.

After the New Year's Day in 2015, according to the agreement, five CNC machine tools entered the workshop of Guanghong Machinery. When the installation and commissioning were qualified and put into production, Guanghong Machinery discovered three CNC machine tools - two F500/50 CNC machine tools. The model of the F650/50 CNC machine tool began to have the performance of “unacceptable” – it did not meet the accuracy standards agreed in the technical agreement, resulting in the production of products are waste products. It’s a pity.

After the machine was in a situation, Guanghong Machinery began to report the situation to Beijing Delite and sought a solution. “About in March 2015, Guanghong Machinery called me and asked that there was a problem with the equipment. I needed to repair it. I transferred it to the technician. The technician judged the quality of the four-axis turntable. The modern Weiya manufacturers also think so. Let Guanghong Machinery find a manufacturer that produces four axes." Gui Jiguo, the original sales manager of Beijing Delite, recalled.

Subsequently, in the three months, no matter whether it was a four-axis manufacturer or a technician from Beijing Delite, it was still unable to “cure” the “faults” of the three devices. Finally, the four-axis manufacturer set up a “military order”. It clearly stated that the quality of its own products was not until the technical personnel of Hyundai WIA entered the Guanghong Machinery in June last year.

In July 2015, after a month or so of investigation, the technicians of Hyundai WIA finally found the cause of the three machine tools. By changing the temperature of the oil cooler from 40 degrees Celsius to 25 degrees Celsius at the factory setting, the three devices finally started to operate normally.

Therefore, imported machine tools are not necessarily invulnerable, and there is no need for myths. Foreigners are also human beings, and the machine tools produced will also malfunction. Do not blindly believe in superstition. On the contrary, domestic machine tools also have good products and should not be killed by a stick.

The following is the statistics of the import and export of the machine tool industry in the first half of this year:

In the first half of 2017, the machine tool industry imported and exported 11.67 billion US dollars, an increase of 6.52% over the first half of 2016 (hereinafter referred to as the same period). Among them, imports were 6.548 billion US dollars, up 4.13% year-on-year; exports were 5.123 billion US dollars, up 9.73% year-on-year. The import and export deficit was 1.425 billion US dollars.

1. Imports of metal processing machine tools declined, and imports of metal cutting machine parts and accessories increased sharply. The decline in imports in the whole industry in 2016 was double-digit, and it increased to growth in the first half of 2017, indicating a slight increase in domestic demand. Metal processing machine imports 39,400 units in the first half of the year, 3.816 billion US dollars, the amount decreased by 1.95%. The processing center imported 13,300 units, 1.45 billion US dollars, and the amount dropped by 3.97%.

2. Exports decreased from decline to growth, and the export of CNC horizontal lathes increased rapidly. The industry's exports in 2016 decreased year-on-year in 2015, and the growth in the first half of 2017 turned to growth, indicating that the export situation has improved. Metal processing machine exports in the first half of the year was 1.478 billion US dollars, an increase of 6.94%.

In general, the progress of China's machine tool industry is obvious to all. It is necessary to know that the ecological environment, R&D design, business philosophy and management level of China's machine tools are not as good as those of foreign countries. However, under such circumstances, China's machine tool industry is still developing and improving. Why can we not give the domestic machine tool enterprises some tolerance and growth time, and prove their chances for domestic machine tools? I believe that as long as we continue to work hard, one day, our machine tool technology will surpass foreign countries. The future must belong to China and belong to us.
