“It'sallaboutyou†is the slogan of Mazak's publicity at the 2015 EMO exhibition. It demonstrates the development concept of its products and technology based on user needs by displaying typical processing techniques and machine tools. It is reported that the Mazak has exhibited a total of 9 five-axis machine tools and composite machine tools, accounting for more than 40% of all display machines. Although there are not many new exhibits and technologies, the practical, systematic and application-oriented display solutions have more comprehensively demonstrated the technical strength and development level of Mazak. The outstanding concepts and exhibits in the five-axis and composite machining technology are as follows.
DONE-IN-ONE
The "DONE-IN-ONE" concept refers to the process of processing all the parts of a part blank on a machine tool and directly obtaining the final product.
By integrating the traditional multi-process discrete production line layout into a single machine tool, this new process can greatly reduce production turnaround time, improve machining accuracy, reduce plant area, equipment investment costs, and reduce and reduce operational requirements. And improve the working environment and so on. Therefore, this process concept not only simplifies the production system, but also enhances production management.
One-time processing is the ultimate goal pursued by researchers in the world of composite processing technology. From the initial processing method of composite (turning and milling compounding, grinding / milling compounding, gear processing, five-axis surface machining, etc.), to the integration of different processes (loading, welding, heat treatment, processing, measurement, cleaning, marking) Etc.), getting closer and closer to achieving the goal of completing all the processing in one setup.
Behind this progress is not only an in-depth study of different processes and equipment, but more importantly, an in-depth understanding of typical manufacturing processes in specific user areas, and continuous tracking and accumulation. Only a skilled user of a certain field can undertake the research and development of composite processing technology and equipment.
It can be said that the five-axis machining machine is evolving to the needs of users. Since the birth of the five-axis machining machine, it has been continuously researched and evolved from the research on the realization of five-axis machining technology to the specific five-axis machining requirements of users. From the exhibits of this exhibition, the special performance of the five-axis machine tool is more than a pure technical demonstration, and the five-axis machine tools for production and application have different adjustments for the specific user field. Thanks to this targeted development, the five-axis machine tool has a great improvement in balance accuracy and efficiency.
Cross-technology composite
Cross-technology composites are also a bright spot in the latest developments in composite processing technology. The outstanding representative is the recombination of additive manufacturing technology (AM) and turning and milling (milling) composite processing technology, forming a new integrated manufacturing process from blank preparation, local anisotropic material growth to all-in-one processing.
With the deepening of research, the technology and prototype have gradually formed experiments in practical applications, and continue to broaden the scope of application. The more representative exhibits at this exhibition are as follows. DMG-MORI's LASERTEC43003D and five-axis turning and milling machining center LASERTEC43003D, X/Y/Z axis travel: 750/210/1550mm, additive manufacturing specification (D×L): 覫600mm×覫1500mm.
In the latter case, the machine tool is directly deposited by the laser nozzle, and the processing efficiency is 20 times that of the powder-added additive manufacturing technology. The two-piece spindle (C-axis) structure allows the hexahedron to be machined and exchanged. The lower tool holder can be used as an auxiliary support during the turning and milling process when needed. With a laser head power of 3kW to 10kW, it can handle different process requirements such as deposition stacking, heat treatment and welding. It can combine metal of different materials on one part.
WFL is a well-known Austrian company in the world of large-scale milling and compounding technology. This time, the company exhibited the M80 milling and turning machine for composite laser additive manufacturing. The M80 milling machine with modular design concept integrates a 6kW high-power laser to weld the surfacing on the part and harden the surface of the workpiece where wear is possible. The use of superior milling, turning and cavity machining technology has greatly expanded the application areas of composite machining technology and machine tools.
These studies not only let you see the broad development prospects of additive manufacturing technology, but also cause us to pay attention to the importance of cross-technology research. This shows that “cross-border integration†may be an important way to upgrade the technology.
