CNC machining center is a new processing method based on traditional machining methods, the processing technology of new technology .It improves the accuracy and efficiency of the production of the workpiece, the traditional NC milling composite center comparative advantage can reduce clamping times, improve processing precision, shorten the product manufacturing process chain, improve production efficiency and less area, reduce several production cost and so on.


China in 2001 by the Shenyang CNC machine tool factory produced China's first SSCKZ63-5 CNC machining center machine tool, the introduction of the German company Thomas Liao pull (MAXMULLER) technology, the time to reach the international level at the end of 90s, although the late start, the starting point is still high.


Due to the fact that our overall technical foundation is not very solid, compared with foreign technology, we lack of decades of experience accumulation, and the processing methods and technology are relatively weak.


In the NC machining center machining efficiency, composite CNC milling lathe machining center model can load more special cutting tools, tool arrangement and traditional NC machine is completely different, can reduce the tool change time, improve processing efficiency, to achieve a complete clamping process can control all or most the machining center, thus greatly shorten the product manufacturing process chain. On the one hand reduces the clamping change in the producing time, but also reduces the manufacturing tool and waiting period, good saves the cost of production.


The number of cards in the improvement of precision reduction to avoid the accumulation of errors due to CNC machining center location datum transformation, high strength body design integration, improve the difficult cutting materials processing capacity of composite gravity, CNC milling lathe machining center model can achieve the key data in the process of manufacturing and precision control in in contrast to previous detection, you can achieve a good production and improve product processing precision.


Secondly, for NC milling machining center has saving in production costs can also see the appearance, compact design to improve space utilization, maintenance can be more convenient, the equipment price of single CNC milling composite center high at present, but is to reduce the manufacturing process and equipment required for flash flat and maintenance costs can be very good for the production operation and management costs play a very good control.

Machine Tool Industry Top Ten Keywords in 2017

D&S Trading Co.,Ltd. is professional machine trading company, which respresative for our relative factorys.We supply you first class quality machine with best service. Our machine include all faucets, valve, brass fitting, cartridge, brass parts,brass bar cutting machine, teflon tape machines.

Machine Tool Industry Top Ten Keywords in 2017


1. Innovation After experiencing the winter of machine tools, innovation has become a problem that machine tool companies have to solve. In fact, it is not only machine tool companies. For the entire manufacturing industry, innovation in 2017 is a popular word. In 2017, the innovation of machine tool companies is reflected in the achievement of a technological achievement. Jinan No.2 Machine Tool, Shenyang Machine Tool, Qinchuan Machine Tool, Pushkin River and other companies successively broke through the national special issues in 2017, adding a brilliant touch to China's machine tool technology innovation. The transformation, upgrade, and adjustment of structures have also become the highlights of machine tool companies in 2017.


2. High precision If in the past the machine tool industry was "big but not strong" and "low-end flooding", then in 2017, "high precision" became the development goal of machine tool companies. With the development of the manufacturing industry, the customer's requirements for machine tools are constantly increasing. Before the price alone, the price alone will not work, and the fight against the market is the hard truth in the fight for product and quality. The advancement of machine tools towards “precision” is not only the country’s slogan, but also the intrinsic requirement of the market for companies in 2017.


3. The transformation and upgrading For machine tool products, we must innovate and develop to form our own competitiveness; for machine tool companies themselves, we also need to upgrade and upgrade their quality and efficiency. In 2017, the most dramatic change is the stock market, and the stock market also reflects the status quo of business operations. After successive machine tools companies such as Shenyang Machine Tool, Kunming Machine Tool, and East China CNC Machine Co., Ltd., Shenyang Machine Tool took the lead in reforming the first step: adjusting the business model and developing shared machine tools. Under the drastic reform of Shen-machinery, news was recently reported that Shenyang Machine Tool is expected to achieve profitability in 2017. Enterprises need to follow the market. In the context of overcapacity in the machine tool market, declining profits and rising demand for high-end products, the machine tool companies themselves must make adjustments. Whether it is the "i5" new model or the reorganization of assets, it is an inevitable requirement for development. Xiao Bian boldly predicted here that in 2018, the transformation and upgrading of machine tool companies will continue to be the industry's key words.


4. Intelligent machine tools We are not unfamiliar with CNC machine tools. Have you understood the concept of intelligent machine tools? In the general situation of CNC machine tools, a new word was born in 2017, namely the intelligent machine tool. An intelligent machine tool is a machine tool that can make decisions during the manufacturing process. Yes, in the future, a machine tool can decide on production. It will control the angle and time of the process itself, perform conscious repair of various deviations in the process of reproduction, and give an optimal solution by calculating the processing time and the service life of the components. Xiao Bian thinks that intelligent machine tools will become another industry development trend after CNC machine tools.


5. No chemical plant Baidu Encyclopedia defines: unmanned factories are also called automated factories, fully automated factories, which means that all production activities are controlled by electronic computers, and the production line is equipped with robots and factories without workers. Machine tool companies also entered the era of unmanned people in 2017. At the Shanghai Industry Fair in 2017, major international companies such as KUKA, Bosch, and ABB demonstrated their own automation solutions. Exhibitors can experience a fully automated “unmanned factory” at close range. Domestic companies such as Suzhou Bozhong Seiko Co., Ltd. and Shanghai Wodi Intelligent Equipment Co., Ltd. are also showcasing their unparalleled presence in the "unmanned chemical plant." In fact, “unmanned chemical plants” are gradually increasing in China. For companies that require high-precision machining, such as machine tools, “unmanned” will be another major trend.


6. Robot All say "Human-Machine Cooperation", Xiao Bian thought that in 2017, this "person" can be changed to "robot", and this "machine" can also be changed to "machine tool". In automated production lines, the cooperation of robots and machine tools is becoming mainstream. For example, Huazhong CNC and other well-known machine tool companies have focused on robots in 2017. Xiao Bian believes that in the future, people and machine tools will really be replaced by the cooperation of robots and machine tools, and people will supervise the normal operation of these machines as managers.


7. Shared machine tools In 2017, I have to mention the concept of shared machine tools. Sharing is sharing. After sharing companies such as sharing bikes, sharing umbrellas and sharing charging treasures, sharing is no stranger to everyone. The most typical application of “sharing machine tool” is the i5 of Shenyang Machine Tool. The I5 mode is an enterprise that requires machine tool processing to use the i5 (i5, namely industrialization, informatization, networking, intelligentization, and integration) intelligent machine tools to realize the leasing of machine tools through the Internet, paying by the hour or processing volume. This not only allows expensive machine tool equipment to be shared, but also provides a secure entrepreneurship platform for self-employed entrepreneurs. For machine tool companies, it also indirectly broadened the market, digested the production capacity, and realized the return of capital and income generation.


8. Industrial Internet of Things In the past, machine tools did not seem to have much to do with the network. In 2017, the machine tool also embarked on the "IoT" road. The application of industrial Internet of Things not only greatly increases the degree of intelligent production, but also shortens the distance between manufacturers and users. For example, the jewellery processing machine tool of Shenyang Machine Tool Co., Ltd. can realize online orders and personalized production, providing one-on-one customized services for customers. The i5 is also one of the typical applications of the Internet of Things. If each machine tool can be interconnected in the future, the future, including the machine tool industry, will form an enormous information network that is not inferior to the current Internet.


9. Precision manufacturing Another key word for the 2017 machine tool industry is "precision manufacturing." The machine tool is called an industrial master machine, and precision manufacturing is more important for important areas such as aerospace, shipbuilding, and equipment. In 2017, the machine tool made a breakthrough in precision manufacturing. The successful capping of the Dalian Koyo Tibetan-style constant temperature and humidity plant means that China's machine tools are beginning to move toward high precision and high levels. However, the machine tools with an error of less than one-hundredth of a millimeter produced by Dalian Guangyang also make China's precision manufacturing a place in the world.


10. Exports In the past, machine tools were mainly imported. In 2017, machine tool exports became new keywords in the industry. Taking metal processing machine tools as an example, as of October 2017, the cumulative number of machine tool exports increased by 7.7% from the same period of last year, and the amount increased by 8.5. Exports rose sharply in line with industry development. In 2017, not only did the domestic machine tool makers actively explore overseas markets, but machine tool small and medium-sized enterprises were not to be outdone. According to Xiaobian, Southeast Asia, Africa and other regions have become the main areas for machine tool SMEs, and overseas businesses have also been valued by companies. The development of machine tools is booming. Through the 2017 industry keyword review, it is not difficult for us to find that China's machine tools are developing towards high-end, smart, and precision. Looking ahead to 2018, it is difficult to predict which words will be continued in the industry key words and which words will appear again. However, Xiao Bian believes that in 2018, the development of the machine tool industry is worth the wait.

My opinion on domestic machine tool industry production capacity

D&S Trading Co.,Ltd. is professional machine trading company, which respresative for our relative factorys. We supply you first class quality machine with best service. Our machine includeall faucets, valve, brass fitting, cartridge, brass parts, teflon tape machines.For more information,welcome to visit our company's website desuautomatic.com


In January 15th, Japanese Industrial Association released data, the amount of the whole year of 2017 the Japanese machine tool orders (preliminary value) rose 31.6% to 1 trillion and 645 billion 516 million yen. Among them, Chinese demand accounted for 1 trillion and 10 billion yen, compared to the same period last year increased 41.2%. more than ever a record in 2007, after a lapse of 10 years once again set a record, a record of Chinese machine tool orders record.


Why the sudden surge in orders so much, because the domestic machine tool industry production capacity, leading to seek foreign products? The answer is obviously not. In fact, a few years ago China has surpassed Japan to become the world's first machine tool production in.2012 years, the world's 28 main production machine tool product countries and regions reached $94 billion 340 million; among them, China machine output value reached 27 billion 540 million yuan, accounting for 28 of the world major countries and machine production The total output value of the 29.19% District, ranked first in the world. Surprisingly, it is the world's largest producer of the machine, but not enough to supply the domestic machine tool market demand.


The reason?


A. industrial upgrading and emerging manufacturing industry in the development of Japan's industrial association mentioned in the report: China of Japanese machine tool the recovery of demand, the main reason is the ongoing new upgrade Chinese enterprise. New upgrade here refers to the present stage of our country's industrial structure adjustment and transformation and upgrading.

In the past year, because of sluggish domestic demand, overcapacity and other reasons, the domestic machine tool enterprises have to face the new pattern of the industrial transformation and upgrading of manufacturing enterprises the low-end is trying to from the low technological content, low innovation ability to climb out of the mud, improve the level of manufacturing industry, to develop high-end market. This upgrade naturally not The high-end machine help, no high-end machine cannot produce high precision, high technology products, no product can talk and upgrade.


Chinese as the world's largest producer of machine tools, the lack of, or just the weakest link is the high-end machine industry. Industry in China facing the innovation ability of high-end machine is not strong, the efficiency is low, the degree of information shortage; for new products, new technology research and development investment in new technology; programming function of the use of advanced cutting tool application is not enough; the popularity of tooling design obsolete and so on many problems. On the other hand, in the background of the global slump, but the development of new manufacturing China rapidly, including automotive, robotics, mobile phone industry has developed rapidly.


The rapid development of the industry put forward higher requirements. The industrial robot as an example, the past two years due to intelligence made fire Hot, the rapid development of the domestic industrial robot industry. Industrial robots in order, according to the Japan Robot Association statistics, Japan in the 2 quarter of this year exports robot also rose by 33.2%, reached a high of 176 billion 500 million yen (about 10 billion 400 million yuan).


And the mobile phone industry, the growing prosperity of the domestic mobile phone also put forward higher the requirements of the machine tool industry. Full screen, curved screen, metal frame, ceramic frame, process more and more beautifully in processing tool needs more and more high-end. But fortunately, Shenyang machine tool and as a representative of Chinese Dazu laser machines and laser industry, the rise of the mobile phone industry in a few to share.


Two, the machine tool industry itself the predicament of talking orders, talk about industry issues. The market is cruel, must abide by the law of survival of the fittest. Excellent left inferior will be eliminated.


So the machine tool industry.


Most of the domestic machine tool companies are currently in an awkward situation: "not high, not low." technology, innovation and other aspects to support among the high-end market, while the inherent original still in the low-end market has a foothold in the market, and will not be completely out in the high-end market competition, domestic machine tool directly facing the world's most advanced technology of machine tool industry, leading enterprises in Germany, Japan and other developed countries competition, such as TRUMPF, Makino, Mazak, Makino, MITSUBISHI heavy machine industry giants. These enterprises machine accuracy, performance is the top of the world on the domestic machine tool does not account for any advantage in these areas.


However, these high-end machine price is equally unacceptable, hundreds of millions, for the low-end manufacturing enterprises, unable to bear Such a high price of the machine. So in the low-end market has been the main position of domestic machine tool. However, it is not so easy, Taiwan province has a low-end, India and other Southeast Asia competition. Such as Taiwan, Dongtai, with friends of Kerry, Taichung, Yawei machine enterprises etc., they are all powerful competitors, the inland areas of machine tool enterprises in 2016 year, Taiwan area Chinese in mainland China imported CNC lathe source, the number of listed first; the amount of second.


The average price for Chinese, the average price of imported CNC lathe 55%. although the tigers camouflage, fierce competition, but one thing is gratifying, in the end the domestic market there are still a big piece belongs to the domestic machine tool, and more and more domestic manufacturing plants are also starting to use the domestic machine tool. On the three, breaking the advice a little to make us feel awkward: Chinese manufacturing industry's recovery and rebound, the first benefit is the Japanese machine tool. But no matter how to say, this thing is more like to give us a warning, domestic machine tool really need to high-end. Or it will be stuck in my throat, hard to swallow.


1. innovation: CNC machine tool industry today, to enhance the competitiveness of the industry, wide support to go on the market, the development of high-end route. While the innovation is the basic driving force of the development of machine tool industry, want to realize CNC machine tool industry to raise the level of technology, we should pay attention to innovation platform construction. On innovation, in China's high-end CNC machine tools and basic manufacturing equipment major science and technology conference, deputy director the Ministry of industry and information technology equipment industry secretary Luo Junjie mentioned "CNC machine tool to overall breakthrough should continue to play the innovation advantages of China characteristics, the concentration of various innovation resources, continue to promote, for a long time to work.


2. time: we need to process, machine tool design, system development, technological process, technological development, the developed countries need to process. The machine tool industry history of nearly a hundred years, China's machine tool industry started slow, but the rapid development in Shenyang. Led by the machine tool machine tool enterprises have their own operating system and the intelligent machine, while the top precision products less than top companies, but it is not far off.

The common tool matching method used in NC machining center


To put it simply, the common tool matching methods used in NC machining center are mainly cutter alignment, automatic cutter alignment and trial cutting method, etc. Due to the complete machining process of a workpiece, several or even dozens of tools may be involved. Because the trial cutting method is relatively primitive and the precision of knife alignment is poor, it is seldom used. We should take a look at the first two more typical knife alignment methods:


1. Automatic alignment method

The automatic tool alignment is realized by the tool detection function configured in the NC machining center. This device can automatically and accurately measure the length of each tool in each coordinate direction, and can automatically correct the error of the tool. The whole process of detection and correction can be realized on the basis of the normal operation of the machine tool. The tool alignment method is completely realized by electronic control device, eliminating the error of artificial tool alignment, so the accuracy of tool alignment is higher. The knife is also more efficient.


2. Tool alignment method

Because of its high economic type, the knife alignment instrument is adopted. It is the main method of the NC machining center now. The cutter alignment is divided into two kinds: the inside tool and the outside tool. The outside tool need to be corrected in advance outside the machine tool. The knife is then mounted on the machine tool and can be used; The tool alignment instrument is a method of measuring the tool installed directly on a fixed position of the machine tool.


The preventive measures of knife error.


Because of the variety of tools used in NC machining center and the disunity of tool size, the tool alignment method should be selected according to the actual machining conditions, and the program instructions should be determined. Even so, there may be some errors in different tool alignment methods, which will affect the machining accuracy of the workpiece.


When the instrument is used, the error is not mainly caused by the error of the manufacture, installation and measurement of the instrument, and the error is also caused by the poor skill of using the instrument. We should pay attention to the installation and measuring accuracy of the instrument, and more importantly, master the correct method of using the instrument. Only by using and operating correctly can the error be reduced to the minimum. At the same time. The quality and rigidity of the cutting tool and the precision of the machine tool itself are also the reasons that affect the tool alignment error. Therefore, it is also important to select the tool of qualified quality and check the 00:00 drift of the NC machining center periodically.
