    99%的人不知道:高精度立式加工中心的精度由这几个因素决定

    高精度(du)立式加(jia)(jia)工(gong)(gong)中(zhong)心可自动完成铣、镗、钻、扩(kuo)、攻丝(si)(刚(gang)性攻丝(si))等(deng)多种工(gong)(gong)序的(de)(de)(de)(de)加(jia)(jia)工(gong)(gong),用途广泛,特别适用于(yu)加(jia)(jia)工(gong)(gong)各(ge)种形状(zhuang)复杂(za)的(de)(de)(de)(de)二、三维凹凸模型(xing)及复杂(za)的(de)(de)(de)(de)型(xing)腔和表面(mian)。适用于(yu)板类(lei)、盘(pan)类(lei)、壳体类(lei)等(deng)精密零件的(de)(de)(de)(de)中(zhong)小批量生产。泛应用于(yu)航空、航天、汽车零部件及模具(ju)等(deng)行业(ye)的(de)(de)(de)(de)三维复杂(za)零件加(jia)(jia)工(gong)(gong)。其实机(ji)床的(de)(de)(de)(de)精度(du)高低直接(jie)决定了加(jia)(jia)工(gong)(gong)的(de)(de)(de)(de)成品率,高精度(du)的(de)(de)(de)(de)机(ji)床对降(jiang)低不(bu)良品、减少生产物(wu)质损(sun)耗起(qi)到非常(chang)重要作用,机(ji)床的(de)(de)(de)(de)精度(du)是衡量机(ji)床性能(neng)的(de)(de)(de)(de)一项重要指标。影响(xiang)机(ji)床精度(du)的(de)(de)(de)(de)因素很多,机(ji)床本身(shen)的(de)(de)(de)(de)精度(du)是一个(ge)主要因素,高精度(du)立式加(jia)(jia)工(gong)(gong)中(zhong)心的(de)(de)(de)(de)...
