【正文】 tube。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 field engineering firm, mountain this engineering 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。 Movement vice between friction coefficient small, the transmission is ceaseless。s model。 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 江漢大學機建 學院 2020 年畢業論文 外文翻譯 第 16 頁 entire machine installment and debugging. After the lathe transforms, processing effective stroke X/The Z axis respectively is mm。 Maximum speed X/Y/The Z axis respectively is 3000/1000/600 mm/Min。人們不得不采用數字邏輯電路 搭 成一臺機床專用計算機作為數控系統，被稱為硬件連接數控（ HARDWIRED NC），簡稱為數控（ NC）。近半個世紀以來，數控系統經歷了兩個階段和六代的發展。 Retained the original main axle system and the cooling system。. The engine bed three coordinates linkage may plete each kind of plex curve or the curved surface processing. 2nd, transforms the C6140 lathe with GSK980T and the exchange servo drive system sds In 2020, with Guangzhou numerical control plant production GSK980T numerical control system, the DA98 exchange servo unit and 4 locations automatic tool rests to an electrical machinery branch factory C6140 lathe X, the Z two axes carries on the numerical control transformation。 Maintenance maintenance request。 Native corporation like China Mount Everest Corporation, Beijing astronautics engine bed numerical control system group pany, Central China numerical control pany and Shenyang 江漢大學機建 學院 2020 年畢業論文 外文翻譯 第 12 頁 upscale numerical control country engineering research center. When choice numerical control system mainly is each kind of precision which the engine bed must achieve after the numerical control transformation, actuates the electrical machinery the power and user39。s, at the beginning of the 8039。 1959 second generation of transistor。 Second is NC, the addend reveals the installment on the ordinary 江漢大學機建 學院 2020 年畢業論文 外文翻譯 第 8 頁 engine bed, or adds the numerical control system, transforms the NC engine bed, the CNC engine bed。 The power is big。 Retained the original main axle system and the cooling system。 Maximum speed X/The Z axis respectively is 。 Manual enters for speed X/Y/The Z axis respectively is billion mm/Min。隨著元器件的發展，這個階段歷經了三代，即 1952 年的第一代 電子管； 1959年的第二代 晶體管； 1965 年的第三代 小規模集成電路。從此，傳統機床產生了質的變化。s another model。 The engine bed processing precision achieves 177。 New system functional scope, application method and with old system difference。 Moreover, because many years use, the operator already understood to the engine bed characteristic, uses and services the aspect to train the time in the operation short, effective is quick. The transformation engine bed as soon as installs, may realize the capacity load revolution. may fully use the existing condition May fully use the existing ground, does not need to like buys when the new equipment such to have reto construct the ground. may use the newest control technology enhances the production equipment the automated level and the efficiency, improves the equipment quality and the scale, alters to the old engine bed now the horizontal engine bed. Fourth, numerical control system choice When the numerical control system mainly has three kind of types, the 江漢大學機建 學院 2020 年畢業論文 外文翻譯 第 10 頁 transformation, should act according to the special details to carry on the choice. Stepbysteps the open system which the electrical machinery drives This system servo drive mainly is stepbysteps the electrical machinery, the power stepbysteps the electrical machinery, the battery solution pulse motor and so on. Entering sends out which by the numerical control system for instruction pulse, after the actuation electric circuit control and the power enlargement, causes to stepbystep the electrical machinery rotation, through gear vice and ball bearing guide screw vice actuation executive ponent. So long as the control mand pulse quantity, the frequency as well as the circular telegram order, then may control the executive ponent movement the displacement quantity, the speed and the heading. This kind of system does not need the physical location and the velocity feedback which obtains to the input end, therefore called it the open system, this system displacement precision mainly decided in stepbysteps the electrical machinery angul
