近幾年，各類卷板機向大規格化發展成為突出特點。“重大專項”中所需高檔數控卷板機的規格越來越大型化。需要的大型數控金切卷板機中，數控折彎機的折彎長度達到12m，數控機械壓力機公稱壓力達到5000t，數控液壓機的公稱壓力達(da)(da)到l萬(wan)t。除了大(da)型(xing)卷(juan)(juan)板(ban)(ban)(ban)(ban)機(ji)以(yi)外，我國在重(zhong)型(xing)卷(juan)(juan)板(ban)(ban)(ban)(ban)機(ji)生產中(zhong)具(ju)有一定優勢，如數(shu)控(kong)(kong)重(zhong)型(xing)卷(juan)(juan)板(ban)(ban)(ban)(ban)機(ji)基本(ben)上可以(yi)滿(man)足國內(nei)需要(yao)，各(ge)種數(shu)控(kong)(kong)式卷(juan)(juan)板(ban)(ban)(ban)(ban)機(ji)產量(liang)逐(zhu)年增加，國內(nei)約幾十家卷(juan)(juan)板(ban)(ban)(ban)(ban)機(ji)廠能夠生產。數(shu)控(kong)(kong)卷(juan)(juan)板(ban)(ban)(ban)(ban)機(ji)的大(da)規格化(hua)主(zhu)要(yao)是市場需求推動的結果。如發電設備(bei)：火電機(ji)組(zu)超(chao)過60萬(wan)kW、水電機(ji)組(zu)達(da)(da)到70萬(wan)kW、核電機(ji)組(zu)超(chao)過100萬(wan)kW，這些發電機(ji)組(zu)的轉子加工(gong)需要(yao)數(shu)控(kong)(kong)卷(juan)(juan)板(ban)(ban)(ban)(ban)機(ji)。
