【正文】 firm and so on. Numerical control transformation content The engine bed and the production line numerical control transformation main content has following several points: First is extensively recovers the function, to the engine bed, the production line has the breakdown partially to carry on the diagnosis and the restoration。 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 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。 Movement vice between friction coefficient small, the transmission is ceaseless。 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 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。s model。 Manual speed X/Y/The Z axis respectively is 3000/1000/500 mm/Min。 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 entire machine installment and debugging. After the lathe transforms, processing effective stroke X/The Z axis respectively is 。 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。 Maximum speed X/Y/The Z axis respectively is 3000/1000/600 mm/Min。 6 年后，即在 1952 年，計(jì)算機(jī)技術(shù)應(yīng)用到了機(jī)床上，在美國(guó)誕生了第一臺(tái)數(shù)控機(jī)床。人們不得不采用數(shù)字邏輯電路 搭 成一臺(tái)機(jī)床專用計(jì)算機(jī)作為數(shù)控系統(tǒng)，被稱為硬件連接數(shù)控（ HARDWIRED NC），簡(jiǎn)稱為數(shù)控（ NC）。到1971 年，美國(guó) INTEL 公司在世界上第一次將計(jì)算機(jī)的兩個(gè)最核心的部件 運(yùn)算器和控制器，采用大規(guī)模集成電路技術(shù)集成在一塊芯片上，稱之為微處理器（ MICROPROCESSOR），又可稱為中央處理單元（簡(jiǎn)稱 CPU）。早期的微處理器速度和功能雖還不夠高，但可以通過(guò)多 處理器結(jié)構(gòu)來(lái)解決。 總之，計(jì)算機(jī)數(shù)控階段也經(jīng)歷了三代。 PC 機(jī)所具有的友好的人機(jī)界面，將普及到所有的 數(shù)控系統(tǒng)。 數(shù)控未來(lái)發(fā)展的趨勢(shì) 繼續(xù)向開(kāi)放式、基于 PC 的第六代方向發(fā)展 基于 PC 所具有的開(kāi)放性、低成本、高可靠性、軟硬件 資源豐富等特點(diǎn)，更多的數(shù)控系統(tǒng)生產(chǎn)廠家會(huì)走上這條道路。 到了 1990 年， PC 機(jī)的性能已發(fā)展到很高的階段，可以滿足作為數(shù)控系統(tǒng)核心部件的要求。這是因?yàn)樾⌒陀?jì)算機(jī)功能太強(qiáng)，控制一臺(tái)機(jī)床能力有富裕（故當(dāng)時(shí)曾用于控制多臺(tái)機(jī)床，稱之為群控），不如采用微處理器經(jīng)濟(jì)合理。 計(jì)算機(jī)數(shù)控（ CNC）階段（ 1970 年～現(xiàn)在） 到 1970 年，通用小型計(jì)算機(jī)業(yè)已出現(xiàn)并成批生產(chǎn)。近半個(gè)世紀(jì)以來(lái)，數(shù)控系統(tǒng)經(jīng)歷了兩個(gè)階段和六代的發(fā)展。 The smallest motion unit is . 數(shù)控機(jī)床改造 1 數(shù)控系統(tǒng)發(fā)展簡(jiǎn)史及趨勢(shì) 1946 年誕生了世界上第一臺(tái)電子計(jì)算機(jī)，這表明人類創(chuàng)造了可增強(qiáng)和部分代替腦力勞動(dòng)的工具。 Retained the original main axle system and the cooling system。 The manual speed is 400mm/Min。.
