易車鐵光潔性好：經(jīng)車加工后的工件表面光潔度好；4. 易車鐵環(huán)保性：符合歐盟SGS環(huán)境認證標(biāo)準(zhǔn)，并通過瑞士環(huán)境認證。產(chǎn)品可以出口機械設(shè)備：木工機械、陶瓷機械、造紙機械、玻璃機械、食品機械、建筑機械、塑料機械、紡織機械、千斤頂、液壓機等；電器產(chǎn)品部件：電機軸、風(fēng)扇軸、縫紉機軸等；家具：特別是出口金屬家具，如茶幾、椅子、戶外家具；金屬器具：園林工具、燒烤爐網(wǎng)架、螺絲刀、防盜鎖等；小五金零配件：如導(dǎo)軌、機鍵、螺母、螺絲、圓釘、六角釘八角釘以及各種不同規(guī)格標(biāo)準(zhǔn)件等；汽車、摩托車零配件等。計算公式播報編輯易切削鋼圓棒、線材、鋼絲兩種：分別為如下：1.W（重量，kg
