On September 16, 2009, SAACKE, the leading manufacturer of tool and tool grinding machines in Germany, held the 2009 High-efficiency Tool Grinding Seminar in Beijing, and for the first time announced the new results jointly developed by ZOLLER and NUM. Fully closed-loop grinding system. Mr. ZOLLER, President of ZOLLER Asia Pacific, and Mr. Patrick Schmid, NUMROTO Product Manager of NUM, attended the meeting. The meeting lasted for three days and the participants reached more than 100 people.
It is understood that the three companies began to work together on the analysis of tool working conditions in the past few years. At that time, it was found that although there were many improvements in the existing tool production process, the production processes were still not related to each other. This is also the cause of the development of full-closed grinding. Mr. Gerd Hotz, manager of SAACKE's machine tool department and director of Beijing company, said: "This is the first time we have jointly demonstrated the 'full-close grinding process' system in China. I believe this research and development concept will provide users with a more optimized process. Method, thereby reducing its cost, achieving the goal of maximizing efficiency, maximizing profit, and optimizing quality."
In addition, the staff also gave a live demonstration, allowing users to experience the advantages of this full-closed process on the spot, and experienced how the grinding machine, software and measuring instrument work together.
The purpose of using fabric sandwiched rubber sealing material is to increase the stiffness and strength of the sealing ring, prevent rubber extrusion, and make it suitable for high pressure. At the same time, in the process of wear, rubber wears ahead of fabric. When the rubber of the parts with high contact pressure wears off, the wear extends to the parts with low contact pressure, so that the wear of the whole sealing surface tends to be uniform, but the friction does not change significantly. However, the lip of the rubber sealing ring sandwiched with fabric can easily scrape off the oil film on the sliding surface, so the lubricity is worse than that of leather and polytetrafluoroethylene.
