【正文】 Maximum speed X/Y/The Z axis respectively is 3000/1000/600 mm/Min。 The engine bed smallest migration unit is . 3rd, transforms the X53 milling machine with SIEMENS 802S In 2020, the pany invests 120,000 Yuan, with German Simens the 802S numerical control system, stepbysteps the actuation system is the X53 milling machine carries on X, Y, the Z three axle numerical control transformation to pany39。 The transformation two axes have used the roller lead screw and with the ambulacrum transmission system on the machinery. Entire transformation work including machine design, electrical design, engine bed overhaul and 南 京 理 工 大 學(xué) 課程設(shè)計(jì)說(shuō)明 書(shū)（英文翻譯） 17 entire machine installment and debugging. After the lathe transforms, processing effective stroke X/The Z axis respectively is mm。 Manual speed X/Y/The Z axis respectively is 3000/1000/500 mm/Min。s model。 When start moment of force and movement the moment of force approaches, may reduce the electrical machinery to start the moment of force. Therefore may satisfiedly pare the high accuracy ponents processing request. safe protection The effect must take the security as a premise. Transforms in the engine bed must take the corresponding measure according to the actual situation, cuts noticeable. The ball bearing guide screw vice is the precision part, when the work must take strict precautions against the dust is specially the scrap and the hard sand grains enters the roller conveyer. On longitudinal guide screw also coca overall sheet iron safety 南 京 理 工 大 學(xué) 課程設(shè)計(jì)說(shuō)明 書(shū)（英文翻譯） 15 mask. The big carriage with skids two end surfaces which the guide rail contacts to have to seal, prevented absolutely the flinty granulated foreign matter enters the sliding surface damage guide rail. Sixth, After the engine bed electrical system transformation, to operates, the programmers inevitably brings the new request. Therefore ahead of time carries on new system knowledge training to the operator and the programmers to be extremely important, after otherwise will affect the transformation the engine bed rapid investment production. The training content should include the new operation kneading board disposition, the function, the instruction meaning generally。 Movement vice between friction coefficient small, the transmission is ceaseless。 Fourth is the technology renews or the technical innovation, for enhances the performance or the scale, or in order to use the new craft, the new technology, carries on the big scale in the original foundation the technology to renew or the technical innovation, the great scope raises the level and the scale renewal transformation. The new electrical system transforms after, how carries on the debugging as well as the determination reasonable approval standard, also is the technology preparatory work important link. The debugging work involves the machinery, the hydraulic pressure, the electricity, the control, and so on, therefore must carry on by the project person in charge, other personnel coordinate. The debugging step may conform to simplicity to numerous, from infancy to maturity, carries on from outside to in, after also may the partial overall situation, after first the subsystem the The numerical control transformation superiorly lacks reduced investment costs, the date of delivery are short With purchases the new engine bed to pare, may save 60% ~ 80% expense generally, the transformation expense is low. Largescale, the special engine bed especially is specially obvious. The mon largescale engine bed transforms, only spends the new engine bed purchase expense 1/3, the date of delivery is short. But some peculiar circumstances, like the high speed main axle, the tray automatic switching unit manufacture and the installment too requires a lot of work, costs 南 京 理 工 大 學(xué) 課程設(shè)計(jì)說(shuō)明 書(shū)（英文翻譯） 10 a great deal of money, often transforms the cost to enhance 2 ~ 3 times, with purchases the new engine bed to pare, only can economical invest about 50%. machine capability stable are reliable, the structure is limited Uses foundation and so on lathe bed, column all is heavy but the firm casting ponent, but is not that kind of welding ponent, after the transformation engine bed performance high, the quality is good, may take the new equipment continues to use many years. But receives the original mechanism the limit, not suitably makes the unprecedented transformation. familiar understood the equipment, is advantageous for the operation service When purchases the new equipment, did not understand whether the new equipment can satisfy its processing request. The transformation then otherwise, may precisely calculate the engine bed the processing ability。s engine bed transformation industry, also enters from the old profession to by the numerical control technology primarily new profession. In US, Japan, Germany, have the broad market with the numerical control technological transformations engine bed and the production line, has formed the engine bed and the production line numerical control transformation new profession. In US, the engine bed transformation industry is called the engine bed regeneration (Remanufacturing) industry. Is engaged in the regeneration industry famous pany to include: The Bertsche engineering firm, the ayton engine bed pany, DevliegBullavd (are valuable) serves the group, the US equipment pany and so on. The American valuable pany has set up the pany in China. In Japan, the engine bed transformation industry is called the engine bed to reequip (Retrofitting) industry. Is engaged in the reequipment industry famous pany to include: Big indentation project group, hillock three mechanical panies, thousand substitute fields labor machine pany, wild engineering firm, shore fiel
