In the eyes of some Chinese, foreign machine tools have fewer problems and domestic machine tools have more problems, but is this true? Why is this happening?
Imported CNC machining center machine tools are handheld pearls. Imported machine tools are generally regarded as core equipment by users and are only used for precision machining processes. At the same time, they bear the responsibility of the company's facade. The effects of thermal deformation, excavation of surroundings to prevent shock waves to avoid the introduction of vibration waves from other equipment, the operator is the best control master in the company, equipped with fixtures and knives that have been over-balanced, using the best lubricants and Cutting fluid, arrange the optimal level of protection.
The domestic machine tools are "brother-in-law" who do the most tiring, hardest and dirtiest work, and enjoy the worst treatment. "Air-conditioning? Don't make fun, this valuable machine still needs a constant temperature environment?" It is the logic of domestic machine tools to make horses run fast without wanting to graze them. Most of the domestic machine tools are in a chaotic environment, and the accessories and tools can be used. New employees first arrange to train their hands on the domestic machine tools, often overloading the knife. Dirty environment, lack of maintenance, overload operation, and improper use are the four main reasons for the increase in the rate of domestic machine tool faults.
Under such environment comparison, domestic machine tools obviously have no advantages at all. To exaggerate, domestic machine tools are based on the worst use environment as a prerequisite for production. If you look at the imported machine tools that are pampered, the same thing happens frequently.
Now, let's take a look at the side of imported machine tools from the real 中国福彩网 reports.
Shaoxing imported CNC machine tools have hidden dangers within one year
According to statistics, from 2015 to the end of July this year, the Shaoxing Inspection and Quarantine Bureau completed a total of 110 batches of imported CNC machining centers for inspection. The country of origin or region is mainly Taiwan, South Korea, Japan, etc., of which 21 batches are unqualified, and the disqualification rate It is 19% -29%.
According to the analysis, the main reasons for the failure of these CNC machine tools are that there is no Chinese explanation, or no Chinese warning sign, or that the electrical control box is not qualified. In particular, the quality and safety issues of CNC machine tools imported from South Korea are the most outstanding. Of the 16 batches of imported CNC machine tools reviewed, 14 failed batches, and the batch failure rate is as high as 88%. The quality and safety issues are very outstanding.
Quzhou imported equipment "full physical examination" 8 months to recover losses of more than 4 million US dollars
On September 18, Zhejiang Kaishan Group imported a batch of CNC screw rotor milling machines from the United Kingdom. During the unpacking inspection, the staff of the Quzhou Inspection and Quarantine Bureau found that the number of delivered equipment was different from the packing list provided by the British exporter. The company recovered in time an economic loss of 220,000 Euros.
After discovering the problem, the inspectors immediately contacted the British side and confirmed the situation, and coordinated the import and export parties to sign the "Reissue Cargo Agreement" and issued a certificate of inspection for the customs clearance of the company's reissue equipment to avoid repayment. tariff. "Because of proper handling, the current reissue equipment has successfully arrived at the enterprise and entered the device commissioning stage." Zhejiang Kaishan Group official said.
It is reported that from January to August this year, Quzhou imported a total of 149 batches of mechanical and electrical equipment for legal inspection, with a value of 10.87 million US dollars, 12 batches of unqualified products were detected, and a value of 4.04 million US dollars. The batch non-conformity detection rate was 8.1%. The detection rate of non-conformities was as high as 37.2%, which saved more than US $ 4 million in economic losses for enterprises. "The unqualified products mainly include lathes, CNC machine tools, X-ray application equipment and other products," said Ye Meiyan, director of the Inspection and Supervision Department of Quzhou Inspection and Quarantine Bureau.
Henan imported CNC machining center does not work "normally" for half a year. Is this the rhythm of shutdown?
In 2014 (the time is a bit long, but the incident has always dragged on to the present, it is also suffering this company), Henan Xinxiang Guanghong Machinery Equipment Co., Ltd. has successively worked with Beijing Delite Trading Co., Ltd. (hereinafter referred to as Beijing Delite), Hyundai Finance 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 model F400, 2 CNC machine tools of model F500 / 50, and model of F650 / A total of 5 CNC machine tools with 50 CNC machine tools are used to expand production and improve product quality.
After New Year's Day in 2015, according to the appointment, 5 CNC machine tools entered the workshop of Guanghong Machinery. When the equipment was qualified for commissioning and was ready to be put into production, Guanghong Machinery found 3 of the CNC machine tools-F500 / 50 CNC machine tools. Two sets of F650 / 50 CNC machine tools began with the expression of "not admitting to soil and water"-failing to meet the precision standards agreed in the technical agreement, resulting in the products being discarded. What a pity.
After the situation of the CNC machining center, Guanghong Machinery began to report the situation to Beijing Deliit and sought a solution. "Approximately in March 2015, Guanghong Machinery called me and stated that there was a problem with the equipment and that it needed maintenance. I transferred it to a technician. The technician judged that it was a quality problem of the four-axis turntable. Hyundai Weiya also thought so. Let Guanghong Machinery find out the four-axis manufacturers. "Gui Guiguo, the former sales manager of Beijing Delite, recalled.
Subsequently, for a period of up to three months, neither the four-axis manufacturers nor the technical staff of Beijing Delitel still could not “fix” the “disadvantages” of the three devices. Finally, the four-axis manufacturers issued a “military order”. It is clear that the quality of non-own products is not improved until June of last year when the technical staff of Hyundai WIA settled in Guanghong Machinery.
In July 2015, after a month of investigation, the technical staff of Hyundai WIA finally found the reasons for the shortcomings of the three CNC machining centers. After changing the oil cooler temperature from the factory setting of 40 degrees Celsius to 25 degrees Celsius and other methods, the three devices finally started to run normally.
Because the equipment could not work normally for half a year and caused huge losses, Liu Wei has now decided to seek help through legal channels and make a claim to the relevant parties.
Therefore, imported CNC machining centers are not necessarily impeccable, let alone myths. Foreigners are also people, and the CNC machining centers produced by them will also have problems. Don't be blindly superstitious. On the contrary, domestic CNC machining centers also have good products and should not be killed with a single stick.
Generally speaking, the advancement of China's CNC machining centers is well known.
It should be known that the ecological environment, R & D design, business philosophy, and management level of China's CNC machining centers are not as good as those of foreign countries. However, under such circumstances, China's machine tool industry is still developing and moving forward.
Why can't we give the domestic CNC machining center companies more time for tolerance and growth, and prove their timing to the domestic CNC machining center? !!
I believe that as long as we continue to work hard, we believe that the CNC machining center industry in China will one day stand on top of the world like aerospace engineering and infrastructure engineering, and become one of the world's first-class standards!
