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;
Second is NC, the addend reveals the installment on the ordinary engine bed, or adds the numerical control system, transforms the NC engine bed, the CNC engine bed;
Third is renovates, for increases the precision, the efficiency and the automaticity, to the machinery, the electricity partially carries on renovates, reassembles the processing to the machine part, extensively recovers the precision; Does not satisfy the production request to it the CNC system to carry on the renewal by newest CNC;
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
3.3 The numerical control transformation superiorly lacks
3.3.1 reduced investment costs, the date of delivery are short
With purchases the new engine bed to compare, may save 60% ~ 80% expense generally, the transformation expense is low. Large-scale, the special engine bed especially is specially obvious. The common large-scale 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 compare, only can economical invest about 50%.
3.3.2 machine capability stable are reliable, the structure is limited
Uses foundation and so on lathe bed, column all is heavy but the firm casting component, but is not that kind of welding component, 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.
3.3.3 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; 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.
3.3.4 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.
3.3.5 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 transformation, should act according to the special details to carry on the choice. 数控机床改造英文文献和中文翻译(4):http://www.751com.cn/fanyi/lunwen_54038.html
