What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

Research on China’s Auto Parts Exchange Conference


The troublesome thing now is how to become the current domestic scale *big influence *big, *missed the exhibition and did not reserve a booth, some of the exhibitors are finding suitable exhibition halls with a large area and convenient transportation. In addition to the increase in the number of exhibitors, the improvement of the exhibition site layout is also a major feature. Walking into the exhibition site, we can’t help but find that more and more companies have put a lot of effort on the layout of their booths. The unique booth layout attracted more visitors to stop. It has also become an opportunity to showcase the corporate image. According to the organizer, this year’s booths with special decoration (that is, non-standard booths) have reached 30% of the total booths. Following this trend, it will reach 40%-50% in the future. The appearance of more and more “specially decorated” booths will continue to enhance the image and popularity of the Auto Parts Association. The platform effect needs to be continuously strengthened. After nearly 40 years of development, the Auto Parts Association has changed the old image of the mule and horse meeting that year. However, how to further improve the level and effect of the exhibition is still an issue that the organizer needs to consider. In response to this, the organizer has continued to “work hard” on management, improving from each exhibition experience and deficiencies. This exhibition strictly controls the time of exhibitors’ move-in and move-out, changing the embarrassing situation of closing on the opening day in the past. The organizer also hired a professional company to count the detailed information of the audience. And use this to grasp the demand trends of future exhibitions. To provide exhibitors with a rare letter from other than that.

The organizer also held various seminars during the exhibition to provide exhibitors and visitors with necessary channels for technology and information exchange. For example, the 3rd Global Sourcing (OEM) and International Buyers Information Conference held during the exhibition invited buyers from the United States, India, Germany, Denmark, Ukraine, South Africa and other countries to bring direct purchase item. Provide opportunities for participating companies. Another event organized by the organizer is the 3rd China Auto Parts Purchasing, Supporting and Management Forum. The theme of this forum is “the relationship between whole and zero” to discuss the procurement of vehicle companies and the matching issues of parts and components companies. More than 100 companies including Delphi, Wanxiang Group and Dongfeng Industrial Company participated in the seminar. At the same time, there are many opportunities to take the Auto Parts Association as an opportunity. Activities organized by large and medium-sized enterprises and organizations themselves. Such as Yuhuan parts procurement supplier matchmaking meeting, Zhongnan Automobile Port project briefing meeting, etc. With the help of the scale effect of the Auto Parts Fair, some companies also hold the dealer conference and new product promotion conference during the exhibition. Although the number is large, the scale is not large and many business opportunities are missed. If you can communicate more with the organizer, and organize uniformly, arrange the time and venues uniformly, and announce it to the exhibitors and organizations, it will be more thorough and more effective. The auto parts fair also attracted nearly 50 investment promotion groups organized by the National Auto Parts Market Federation. They shuttled between the booths, met old customers, made new friends and tried every means to recruit merchants for their respective auto parts cities. It added a fire to the lively exhibition. The Auto Parts Fair has been successfully held for 56 sessions. From the organization of order fairs in the period of material allocation and distribution in the planned economy era, to the modern auto parts exhibition that integrates display, exhibition, communication and trading. Auto parts will be in continuous development and progress.

Working hard for the end customer market During the visit to the exhibition, the lively training activities of the Uniform Freedom Professional Oil Change Chain Maintenance Center organized by Beijing Tongyi Petrochemical Co., Ltd. attracted the attention of reporters and many visitors. It is not only a promotion and training of franchise, from the perspective of Auto Parts Association. It is also the addition and impact of a new idea that the transformation of the automotive after-sales market from channel to “end market” is taking shape. As we all know, Uni-President is a large-scale professional lubricant manufacturer in China. The competition in the terminal market is currently also the new focus of international competition, so “unification” also follows the trend and advances into the maintenance market. The person in charge of the company said that it will establish 200 “free travel” chain professional oil change maintenance centers across the country, and realize a strategic breakthrough in the retail market through this project, thereby realizing a new transition from product brands to service brands. The contradiction between “recruiting more” and “recruiting good” China is currently the most promising auto market. The development space of the auto parts market is also very large. This is for the auto parts club. It is a very good opportunity. Although the Auto Parts Association has achieved considerable success. But there are still some problems. As the largest domestic auto parts industry exhibition, the scale, grade and effect of the auto parts exhibition still need to be further improved. At this point, the contradiction between recruiting more and recruiting is manifested on the one hand, due to the development of parts manufacturers and distributors, they have increasingly set their sights on the auto parts association; on the other hand. If the organizers focus too much on how to recruit more exhibitors and neglect to control the scale of exhibitors, product quality, brand influence, etc., it may also have a negative impact on auto parts. Therefore, this may be one of the primary considerations for the organizers. Looking at the auto parts meeting in recent years. Although each session has a certain number of foreign-funded enterprises participating. However, the overall scale is not very large and most of them are private enterprises with uneven standards and former state-owned transformation enterprises.
