大连水产学院本科毕业论文（设计） 摘要摘 要我国是世界上机床产量最多的国家，但数控机床的产品竞争力在国际市场中仍处于较低水平，即使在国内市场也面临着严峻的形势：一方面国内市场对各类机床产品特别是数控机床有大量的需求，而另一方面却有不少国产机床滞销积压，国外机床产品充斥市场，严重影响我国数控机床自主发展的势头。这种现象的出现，除了有经营上、产品质量上和促销手段上等的原因外，一个最主要的原因就是新产品（包括基型、变型和专用机床）的开发周期长，不能及时针对用户的需求提供满意的产品。普通机床的数控化改造事业方兴未艾，在我国目前形式下将大批故障机床尤其是一大批闲置的普通机床进行改造、升级，以较小的投入尽快使这批设备在经济发展中发挥效能、创造效益，的确是许多企业的一项不可忽视的课题。关键词: 脉冲发生器，滚珠丝杠，滚珠丝杠螺母副，自动刀架，塑料导轨软带AbstractMy national yes machine output mos statet state in the world,the product competitive power at international market suffer still get off to inferiority level , of the therefor numerically-controlled machine , granted that at home market too be faced with austere posture:on the one hand domestic market versus all manner of tool product especially numerically-controlled machine be covered with demand,whereas on the other hand refuse have got not a little made in ones country tool dull sale overstock,abroad tool product overflow market,had a strong impact on me national numerically-controlled machine independence extend momenta into.show such phenomenal face,except to have got manage upper, product quality upper sum sales promotion instrument good cause besides,the development cycle length of the both one upmost cause namely novelty（include fundamental mode, derivative and special machine）,be be incapable of in season aim at users demand supply satisfied product.General machine tool numerical control melt reclaim undertaking be in the ascendant from, upratein our country for the moment form down move in bulk malfunction tool above all crowd idle general machine tool proceed rebuild, up upgrade,withal lesser project into as soon as possible gotten these batch EQUIPment at economic development exert EFFiciency, create benefit,the one term nonnegligible problem of the forsooth yes heap enterprise.Keywords: I
