本次设计是对CA6140普通车床的数控化改造。在国内，盛行普通车床改造成数控车床，此设计就是针对着这以目的而设计的，这就降低了生产成本，缩短了工业化的进程，同时为广大的生产厂家所接受。
此设计主要是结合国内的具体国情，针对于广大的用户所设计的。远远比不上那些外国的设备所达到的精度。当然，时代在发展，随着我国的正和国力迅速攀升，在不久的将来那些精度要求比较高的数控设备一定出现在中国的大部分企业中。
Along with the science technical fast fierce development, number's controling tool machine has already become the important marking which measures a national machine manufacture industry level.Adopt the economic number controls system to carry on a number to control to turn a reformation to the common tool machine, particularly in keeping with our country the common tool machine own to have great capacity, the small concrete state of the nation of the production scale.The machine electricity integral whole turns a technique to involve a machine, electronics, and control etc. several academicses, is one of the foundation technique and core techniques of modern and industrial most, is the important marking which measures a national development level of the machine material.Although this academics is still be placed in a development a stage, many orieses are still placed in research and perfect stage, it represents the machine industrial technique revolution of ex- follow a direction, is comprehensive another concrete body of national strength now.Therefore, we should value the research of that academics, and strongly develop this academics, contract to wait with day the United States gradually flourishing nation of margin.This design is to control to turn a reformation to the number of CA6140 common lather.At the domestic, the widely accepted common lather reforms into a number to control lather, this design is to aim at this with the purpose but design of, this lowered production cost and shortenned industrialization of the progress is a large production factory in the meantime, house accept.
This design is mainly to combine local concrete state of the nation and aim at at what large customer design.Far and far can not compare with the accuracy that the equipments of those foreign countries attain.Certainly, the ages is in the development, along with our country of positive with the national strength quickly increase, in the near future those greatly parts of business enterprises that the accuracy requests higher number to control an equipments and must appear in China in.
