Machine tool producers to spend a lot of their costs go up in the high-speed processing equipment to improve their production efficiency, such as in the IMTS 2000, you will see the latest grinding, drilling, cutting and gear roller washing method.Faster, more reliable and improve the spindle and machine tool control is to improve the processing yield and productivity of the main factors. "Spindle faster, increasing productivity in a nut shell in" Chris Hetzer said, Hrafton, WI Division Deputy Chief Engineer, that is to say the future will be the emergence of new spindle and there will be a multi-axis IMTS. Hetzer said: "You do have to correct the design of spindle and spindle not only in high-speed operation, and it also has to increase with the rate of production characteristics, this also means that the dynamics of spindle to be able to ensure that the different speeds, different loads and different tool to work under; This spindle had to have a certain degree of hardness, at the same time, he must also possess a certain degree of toughness so that he can stand up to friction, to varying degrees impact, including the tool " An adjustable spindle of the gear can be set within the scope of relatively large diameter, that is, a "adjustable spindle" can be applied in a variety of different hole diameter gear, instead of an ordinary multi-spindle, spindle to reduce wear and tear required spindle length is relatively short, the provincial timber. Wedge spindle clamping devices are used for machining of products as an aid to detection devices, used primarily as a measure of support gear pieces. A set of "adjustable diameter spindle" can be replaced by a different and more with the specifications of the existing "common spindle" role, it is "adjustable mandrel diameter" than the existing "common spindle" use value and market value of more . Hetzer Records, Gilman spindle design of the need to use FEA to ensure that the units and the bonding between units, and in fact this is a fast-running production in the process of spindle a small part, we really want to find these high-speed spindle is in the the production process of its stability, for example, a 170mm spindle in the case of 30KW, its speed is 24000rpm, our customers want their first spindle that is the case, the second is the case, the third is this the fourth the same way ... ... Hetzer said the real intention is to ensure that the bonding between each unit is very difficult to force, it requires that the analysis of the FEA, which includes many things, such as manufacturing tolerances, bearing quality, but the rest of your design and analysis . "Users in a production environment with such high-speed rotating spindle to control a machine, they want to continue to work, but if spindle not such a request", Hetzer said, "people will be scrapping it out -- This is typical in high-speed rotary machine may be what is happening, 大連水產(chǎn)學院本科畢業(yè)論文（設計） 外文翻譯when the spindle to be replaced, but if that were put to the original spindle and spindle that do not have the same cutting characteristics, customers will have to spent a lot of time, a lot of money to let the machine running the same as the original. " In the IMTS in, Gilman will present his 15,000 rev / minute with high-speed spindle drive, the device has a major nylon belt and a cross-cutting structure of the dentate. Gilman also will introduce a new production space of kneading, the system is re-constructed 3-axis space, XYZ module appears in the 400 × 400 × 400 work spaces. Modules to use with multi-axis drive-axis of the heart, but the use of spindle Gilman 'Swedish production of the parent company of SKF cylindrical roller bearings ceramic, Hetzer said the main characteristics of the spindle can not tolerate the energy generated by the high-speed rotation and drive spindle of the Freedom Movement. Hurco provided VMCS new standards 10000 rev / min spindle of, but it can also be changed through the shaft of 30,000 rev / min, so that the formation of a high X and Y axis in the direction of the horizontal speed of 30 m / min , when the Hurco is configured to increase the UltiPro Ш sustained 5.1-6.4 m / minute to process into the accuracy and surface roughness is not affected high-speed motion control software, this unit will be better than the 3-D line work week law . In the grinding equipment, a lot of support to speed up the grinding speed on a special look, and now the latest carbide tools are helping to solve this problem, "faster, faster throughput, faster cycle times is everyone looks forward to the "grinding Jon Wolf, executive vice president of tools and machinery manufacturers Sugino Corp, said," to improve grinding speed-reading the key is to improve the feed grinder, for example, in the 3-axis grinding machine, it the first cycles to provide the smallest (36-51 m / min), but you must have a corresponding feed rate, it can be 8 m / min, it can be 20-23 m / min. "Technology changes constantly, the carbide is the creation of a better tool that can tolerate a higher feed rate and faster speed carbide" Wolf added Road "is the size of the tool edge are becoming more and more diversified, There are a lot of technology in the tool size, it can let you work faster, faster heat dissipation. " Increase in tool life of carbide for each company are looking for, it will make the machine a higher, faster feed rate and processing speed. Machine tool company, we always research techniques in the tool behind the curve, because we always want to keep up with the machine processing, machining and guide people to this industry. Speed and accuracy of processing metal two key factors, but in the process of hole machining, rapid rate of spindle rotation speed does not mean that the efficient, Zagar, vice president Randy Toberts has proved that with his multi - drill shaft or gearbox, Zagar Inc advocate hole at the same time a group of high-speed processing, and not only the processing time of a hole. "Now we see that the rate of Cpk and Ppk rate of 1.33-2.0, the product of these parameters is very important to users, such as an OEM or an automatic control room" Roberts said, "For example, 12 cars GM may need a wheel control center, control center, however the wheels are 5 to 大連水產(chǎn)學院本科畢業(yè)論文（設計） 外文翻譯6 months to drill the hole and head holes, each of them must be maintained 1.67Cpk, each hole has a very high tolerance requirements, location requirements is very high. " "Whether it is cutting or drilling touch, high-speed rotation of the different people in terms of both mean different things." Roberts said, "Under normal circumstances, the speed will affect the speed of rotation, for example, in the traditional processing of a hole the case of "If you, or in a machining center is a single spindle machine would like to carry out the processing of porous, apparently of a single spindle can only be processed once a hole. For how fast you process is not related to processing such as a hole you need to 5 seconds, and processing the two holes will cost you 10 seconds of the time, but would also like to add the machine from the first hole to the second hole time. Processing equipment in the gear IMTS, in the national discussion and mechanical centers, will showcase the latest version of the vertical plane formed by the rolling machine. Wagner said, "is not a traditional scroll parts to the traditional pressure and speed, we are now able to using the latest CNC technology to drive the slider, and it can change the speed of customers as they transform their parts, the most important thing is to spare parts and tool life has increased, " Countries to discuss the PFM / NC that has been sold in 30-year vertical rolling machine nail machine and CNC control, because the machine in a plane perpendicular to the rolling, it formed an important track, Wagner said, it is toward the development of the manufacturing industry and the global optimization of the factory space. PFM machine rolling machine to use 66 percent less than the amount of space and energy, and the quality of it very good " The following products are you IMTS in metalworking and gear molding products Heat compensation Spindle speed based on the scope of self-adjustment to optimize the load to maintain a membrane coupling vibration spindle from the power source and heat isolation of the rock in order to ensure the accuracy of the liquid temperature was controlled from the main components of the machine so the energy cycle to achieve the smallest loss, in order to ensure precise location of claw plate, this machine used a tight joint fixture system, which is the movement of the scope of 1200 × 1000 × 1100mm and load limit is 2,500 kg, the maximum spindle speed is 6000 rev / every minute.
