SAACKE, ZOLLER and NUM teamed up to hold the "2009 Efficient Tool Grinding Workshop

SAACKE China is located next to Caochangdi Art Village, Fuxue Road, Beijing Airport. The artistic aura here seems to connect with several famous European industrial companies - SAACKE, ZOLLER and NUM. They are here to jointly perform a grinding Symphony of cutting edge technology: On September 16, 17 and 18, three “2009 High-efficiency Tool Grinding Seminars” were held. Nearly 200 precision tool grinding professionals from all over the country gathered here in batches to truly witness and feel the cutting-edge level of modern full-closed and efficient tool grinding technology.
Mr. Gerd Hotz, Director of Sack China, Mr. Christoph Zoller, President of ZOLLER Asia Pacific, and Mr. Patrick Schmid, NUM Product Manager, the father of NUMROTO Software, attended the seminars. Feng Huifang, general manager of Sack China, presided over the agenda of the seminar.
In his welcome speech on behalf of the three companies, Mr. Gerd Hotz elaborated on the original intention and significance of the seminar. He said that the theme of the seminar is how modern tool manufacturing processes can adapt to the rapidly evolving world today. Under this requirement, users are maximized, profitable, and optimized. He analyzed that many people are looking for ways to reduce the cost of tooling, thus ignoring the search for a more optimized process to achieve better product quality. Therefore, SAACKE, ZOLLER and NUM have analyzed together in the past few years, and there are many improvements in the existing tool production process, but the manufacturing process still lacks correlation with each other. It is now possible to change this situation by first programming a knife and then transferring the tool parameters to the measuring device after grinding, which has become a necessary procedure for ensuring high precision. Today's processing requirements dictate that it is not enough to get the measurement results. The user needs to transfer the measured parameters back to the grinding software. This true full-closed process will guarantee the highest quality of the tool products, which is based on the close cooperation of the three companies' quality products.
The seminar demonstrated the full-closed grinding process of step drills, end mills and profile cutters. Firstly, the tool has the parameters that are intentionally set with errors. After the grinding process, the tool is measured and the corrected parameters are transmitted back, and the tool is reground, and the high-precision tool product is finally processed. The participants in the seminar experienced how the grinding machine, measuring machine and software work together, and took the lead in understanding the superiority of the cooperation of full-closed machining.
During the seminar, Journal of Tool Technology magazine interviewed Mr. Gerd Hotz, Mr. Christoph Zoller and Mr. Patrick Schmid. Mr. Gerd Hotz first explained that the full-closed tool grinding system is the world's first. In the past, many users in the process of machining tools, grinding machine, measuring machine and software are independent systems, can not form the closed-loop feedback of machining deviation to obtain accurate results, the accuracy of the machining tool depends on the level of the operator. With the development of the world's processing technology, the requirements for tool accuracy are getting higher and higher. The processing of a high-precision tool involves many factors, and it requires a good machine tool, a good measuring machine, good software, and The close cooperation between these people eliminates the errors in each link in time, resulting in high-precision products. Now with such a closed-loop feedback system, it is possible to rely on machine tools and programs to ensure the accuracy and accuracy of the tool. SAACKE is the world's leading tool grinding machine manufacturer. ZOLLER is the world's most advanced tool measuring machine manufacturer. NUM is the best design manufacturer of tool grinding machine software. Through three strong joints, it has developed a full-closed tool grinding machine that has been jointly developed over the years. The cutting system was first shown to everyone at this seminar.
Patrick Schmid further introduced the role of NUMROTO software in closed-loop systems. He said that the tool measurement has been measured with a caliper and later observed on the projector. It is now a high-precision measuring instrument. However, the development of technology requires not only the measurement of the tool, but also the online information feedback of the real-time detection of the processed product, and high-precision compensation. Our software can meet this requirement. There are also two small closed-loop systems in this large closed-loop system. There is a probe on the machine. Through the NUMROTO software, the machining tool can be measured online without taking out the tool. There is also a probe at the grinding wheel that can be given in time. The measured values ​​are eliminated by the world's leading closed-loop system to eliminate machining and measurement errors for the best machining accuracy.
Mr. Christoph Zoller explains the role of ZOLLER's latest "Cocon" software closed-loop system. He said that the two probes on the machine can only obtain simple parameters. After all, all parameters cannot be measured like the measuring machine. Like the flower-like edge of a Christmas tree cutter, the precision is very high, how to detect the deviation, and online feedback, Cocon software solves this problem. It is found that there is a deviation, and this deviation is compensated online, and the deviation is eliminated, thereby processing a high-precision complex molding tool. Because molding cutters are still a bottleneck in China, not many manufacturers can process and produce them. With this "Cocon" software, you can solve the problem of high-precision and complex tools on the Sack grinding machine with NUM software.
In the interview, the three experts also talked about the customer demand problem. They said that some customers still stay at the level of wanting to buy low-cost products, and hope that the price is very cheap. Now China's development speed is still very fast, many customers pay more attention to the quality and precision of the products, which requires manufacturers to produce higher precision machine tools, better measuring instruments, better software, so that their products are not only in China. Leading, also requires to go to the international market. They will seek to cooperate with companies of world-class technology. Of course, these leading companies' products are not the lowest in price, but the products are the best and the returns are the biggest. If you buy some products that are cheaper, it will be risky. The most important thing is that the quality of the products cannot be guaranteed.
In terms of technical support in the market, Mr. Gerd Hotz said that first we have established branches in China, and the localization of technical support is very important. This is one of the most important reactions to the market. We also hold seminars and technical seminars in various forms. In addition, we also provide specialized training for a certain company, and ask customers to go to Sak Beijing for mechanical or electrical learning. At the same time, our technical service staff will provide comprehensive technical services, including technical maintenance. In China, all of our companies offer thoughtful service. Mr. Christoph Zoller added that it is important to create a closer relationship with the user, so that the user does not buy the device and then turn to another, we pay more attention to the user's loyalty and the company can provide the required service according to the characteristics of the user. We place special emphasis on building long-term relationships with our customers, including the provision of spare parts.
These companies have strong R&D teams. Mr. Gerd Hotz said that we are completely independent in the development of various hardware and software, but the company will do some product improvement from the quality and application characteristics of machine tool development and some famous components such as ball screw and grating ruler. Cooperation.
At this seminar, Sac introduced the state-of-the-art grinding center with automatic loading and unloading, with a grinding wheel library and tool magazine. Mr. Gerd Hotz said in a more in-depth analysis. In fact, Sack was the first to launch this kind of grinding center with the loading and unloading in the world market in 1997. 80% of the European market is such a machine tool. This is a kind of machine tool. The trend is that such demand is still small in China. Strictly speaking, it is important to make high-precision tools, equipped with good machine tools, good software, and good detectors. Good operators are also important. The training of good operators is costly and not easy. In order to maximize the advantages of this operator, he hopes that he can operate many devices while making full use of his experience, with automatic loading and unloading. This type of machine tool can solve this problem very well, which is not entirely the reason for labor costs. In addition, through a special program, all in one processing shop is automated, so that unmanned can be realized. This is a future trend in China and there will be a process. Mr. Christoph Zoller also said that in some aviation companies in Germany, due to the processing of special materials, the tool has a thick coating and needs to be ground when the machining wears to a certain extent. Through the very advanced automatic detection system, the grinding is automatically performed according to the amount of wear, which is truly unmanned. Mr. Patrick Schmid also said that they already have software applications for these applications.
Mr. Gerd Hotz also constructively suggested that Chinese customers also need a real understanding of the micron concept. For example, he said that a university professor in Germany gave a standard ball to several famous laboratories for measurement, and there was a deviation in consistency. He said what it really means when our customers' parts are at an accuracy level, to do some analysis and discussion.
Finally, they talked about the current situation in China. They believe that the overall situation in China is still good, but there is no special need to care too much about the global financial crisis. They still adhere to the company philosophy, continue to improve research and development technology, improve product quality, and continue to promote the product market; fully understand the user and communication. This is the best way to face the crisis. You should not over-focus on changing the policies and steps in the crisis situation.
The large-capacity lectures and interactive on-site observations of the SAACKE-ZOLLER-NUM seminar have strengthened and enhanced the customer's integrated processing concept. It is entirely believed that when they return to their respective productions, they will upgrade the product quality to a new one. The stairs.
