DMG's 5-axis machining technology

DMG's 5-axis machining technology

at the end of 1985, DMG launched a CNC rotary table for 5-axis drive operation of universal milling machine. This action laid the foundation for the company's unique success story. In this process, the company has developed into an undisputed world market leader in the field of 5-axis machine tool processing. This important position is mainly reflected in the application in the field of aerospace industry. DMG's universal machine tools, 5-axis machining centers and 5-axis milling/turning centers are adopted by the world's major aircraft manufacturing companies and their international suppliers. Combined with high-tech machine tools from turning, laser and other technical fields, DMG has become an extremely important partner in the international aviation industry. At present, there are more than 200 lithium battery enterprises in China

in addition, Deckel MAHO has always been able to obtain a new method to achieve the machining goal of synchronous 5-axis machine tools. In the past, the CNC rotary table was the ultimate way to achieve this goal, but the various machining combinations available today provide the operator with the possibility to adjust the performance of the machine tool to meet the requirements of different specifications for manufacturing various parts. In this case, the milling head with B-type or A-type control shaft has become the most significant technological innovation by adopting computer-controlled full experimental process. In addition, there are a variety of shaft specifications available, from high-speed motor shafts with rotational speed exceeding the limit of 40000 R/min to powerful 5x torquemaster? For torque up to 795.5 ft./lbs? Drive shaft

the development achievements of control system in the past 20 years are obvious. Today's CNC machine tools are equipped with extremely high-speed information processors, comprehensive three-dimensional functions and 17 in High definition graphic display screen, with more axis positioning processing capacity. Using the complete ATC tuning tool device, the performance of the machine tool can be adjusted to meet different application requirements. At the same time, the impact monitoring device adopts an innovative forward-looking monitoring system, which can ensure that there is no impact during the execution of complex procedures, even if it adopts a "difficult to manipulate" axis configuration

nowadays, the tool capacity of the machine tool has increased to 340 tool positions. This fact is almost insignificant compared with the above-mentioned mechanical and technological leaps. Its significance is more reflected in the comparison between past downtime and current downtime. In the past, the technical specification of MH 700 s machine tool required a tool change time of 30s, but now DMU 100 P duoblock? The tool change time from blade to blade is only 4.5s

the moving distance from the x-axis in Figure 2 is 19.7 in The DMU 50 Evo linear machine has a travel distance of 133.9 inches

provides a variety of possible shaft configurations and various spindle choices from high speed to powerful power

after 5-axis processing is specially applied to the tool and mold industry, this high production rate processing method has also been applied to the production field. The most important application example is reflected in the aviation industry. With the ability to process structural parts and fully meet various standards including standard parts, Boeing's plant in Portland, Oregon uses two DMU 200 p-type machine tools. In addition to some casting "blanks", the workpiece is cut and processed by using the whole aluminum plate, and the dressing proportion is as high as 90%. In this way, it is not difficult to understand that, in addition to the dynamic requirements, the realization of "the most appropriate chip amount" and reliable chip handling in the work area is indeed an important factor. DMU 200 p-type machine tool can calmly meet these challenges. It also dares to meet the challenges brought by the whole processing. CNC rotary table and b-axis with high-performance easy and fast milling shaft and HSK 100 tool connector show excellent performance in this regard. Based on the performance application experience obtained, the Portland factory purchased three additional 5-axis machine tools and 160 p-type machine tools

DMG's 5-axis processing technology is not only successful in the application of aviation industry (European Airbus pays special attention to the whole piece processing technology of Deckel MAHO). Many well-known turbine manufacturers and their suppliers also rely on 5-axis machining expertise from Germany. Volvo aero uses the Deckel MAHO automatic processing system to produce turbine and combustion chamber covers made of high alloy materials with high nickel content. The system also has the function of 5-axis turning. In addition, five types of DMU 160 FD turning/milling machining centers, combined with 100 workpiece pallets and a central tool magazine that can accommodate 1250 tools, are combined into a globally unique machine tool machining center. Based on this excellent application experience, Volvo aero ordered two new sets of turning/milling centers, one DMC 125 FD duoblock? A DMC 200 FD machine tool and a DMC 340 u large milling center. Therefore, DMC series machine tools are mainly used in the pallet replacement system with automatic and efficient exchange of workpiece carrying devices
