subject: The World's Largest Super-size Heavy-duty Cnc Horizontal Boring Lathe In Use - Boring Lathe, Nc, [print this page] 2009 5 months, Wuhan Heavy Machine Tool Group Co., Ltd. Dual-made for the Chinese "Eleventh Five-Year" National Key Project of key equipment?? DL250-based super-heavy-duty 5-meter horizontal CNC boring Lathe Machine delivery, after 4 months of operation, reflecting the good. The equipment has successfully developed and put to use in raising the level of China's equipment manufacturing industry, strengthen our national security and industrial safety is of great significance.
DL250 type 5 meters CNC horizontal boring lathe is a super heavy weight group independent research and development arms manufacture new products is by far the world's largest ultra-heavy duty specification CNC horizontal lathe, can be widely used in hydro, nuclear, marine and aerospace and other industries. The machine weighing a total of 1,450 tons, of which the weight of spindle box reached 177 tons, spindle nose runout and radial runout were within 0.008 mm. Maximum turning diameter of 5 meters, over 4.5 meters in diameter turret Max, Max length 20 meters, maximum 3.5 meters in diameter boring, boring depth of up to 8 meters, the maximum load of 500 tons. In addition to the equipment, heavy-duty horizontal lathe has a basic function, it can be cone, surface, step shaft, groove and thread machining. Configuration of different accessories that you can be milling, grinding, boring and crankshaft processing, and has deep hole boring, automatic tool and workpiece size automatic measurement function.
On this machine has a completely independent intellectual property rights of major technical equipment, the military re-group to achieve three major technological breakthroughs:
(1) of the equipment, high-precision spindle box super heavy weight of large, high strength and rigidity required to reach the current limit of the world's spindle box manufacturing. Takeshige Group, through independent research and development, breakthrough ultra-heavy high-precision hydrostatic spindle bearing this key technology to obtain ultra-high-precision hydrostatic bearing heavy flow, pressure, film thickness and a series of critical data, so that super-heavy high-precision spindle box Hydrostatic radial bearings reached 0.006 mm, living in the world leading level.
(2) Long Bed manufacturing process research and accuracy of the leading domestic level. The machine bed length 45 meters, 1 meter length of the rail to within an arbitrary error of no more than 0.015 mm, 20 m length of any error is not more than 0.16 mm within a length of 45 meters length, not more than 0.27 mm within the error. Takeshige Group uses long copying machine technology, pioneered the successful development of the largest mobile stroke to 57 meters high precision CNC Ssangyong door Portable Boring Milling To ensure the long-bed machining process provides a reliable technical support, and reached a very high linear accuracy.
(3) The Working Group first domestic double three-channel digital control technology and three-axis synchronization. DL250-based CNC heavy sleeper 5 m double Working Group and the three-channel approach to ensure that the two Turning tool Frame and Boring Tool Frame can be completely independent control of feed, improving the processing efficiency, and more convenient operation.
