　　細(xi)長閥(fa)桿加工(gong)(gong)(gong)，一般高溫閥(fa)或者低溫閥(fa)，對閥(fa)桿的粗糙(cao)度(du)(du)(du)值有(you)(you)較高的要(yao)求(qiu)(qiu)，要(yao)求(qiu)(qiu)Ra0.1微米比較普(pu)遍，高光潔度(du)(du)(du)細(xi)長不銹鋼閥(fa)桿加工(gong)(gong)(gong)面(mian)臨一個難題(ti)，磨床磨削過程(cheng)會出(chu)現閥(fa)桿彎曲以及粘砂輪(lun)的問題(ti)，普(pu)通滾(gun)壓手(shou)段對不銹鋼材(cai)質又難以加工(gong)(gong)(gong)，又會產生硬化分離(li)層(ceng)，甚(shen)至微觀(guan)裂紋(wen)，廢品率高。電(dian)致(zhi)伸縮精整(zheng)加工(gong)(gong)(gong)是一種微觀(guan)鍛(duan)打(da)的加工(gong)(gong)(gong)方式，整(zheng)體刀(dao)具作用在(zai)工(gong)(gong)(gong)件(jian)(jian)表(biao)面(mian)僅有(you)(you)3到(dao)5公斤(jin)的力，刀(dao)頭以上千g（重力加速度(du)(du)(du)）密集(ji)鍛(duan)打(da)工(gong)(gong)(gong)件(jian)(jian)表(biao)面(mian)，瞬間將(jiang)(jiang)工(gong)(gong)(gong)件(jian)(jian)表(biao)面(mian)粗糙(cao)度(du)(du)(du)值降低到(dao)Ra0.1微米以下，而(er)工(gong)(gong)(gong)件(jian)(jian)不會有(you)(you)其他(ta)加工(gong)(gong)(gong)工(gong)(gong)(gong)藝造成的缺陷，反(fan)而(er)可以將(jiang)(jiang)工(gong)(gong)(gong)件(jian)(jian)的表(biao)面(mian)殘余應力消(xiao)除(chu)掉，同時工(gong)(gong)(gong)件(jian)(jian)的疲勞壽命、耐腐(fu)蝕性等大幅度(du)(du)(du)提高。
