style="text-indent:25px">鈑金車間加工部件的加工步驟為：產(chǎn)品前期試驗(yàn)、產(chǎn)品加工試制和產(chǎn)品批量的生產(chǎn)。在產(chǎn)品加工試制步驟時(shí)，應(yīng)及時(shí)與顧客溝通聯(lián)系，得到相應(yīng)加工的評(píng)價(jià)之后，再進(jìn)行產(chǎn)品批量的生產(chǎn)。激光打孔技術(shù)是激光材料加工技術(shù)中早實(shí)現(xiàn)實(shí)用化的激光技術(shù)。鈑金車間中激光打孔一般采用的是脈沖激光，能量密度較高，時(shí)間較短，可以加工1μm的小孔，特別適用于加工具有一定角度和材料較薄的小孔，還適合加工強(qiáng)度硬度較高或較脆較軟材料的零件上的深小孔和微小孔。激光可實(shí)現(xiàn)燃?xì)廨啓C(jī)的燃燒器部件打孔加工，打孔效果可實(shí)現(xiàn)三維方向，數(shù)量可達(dá)到上千個(gè)。舟山鈑金加工金屬板材加工就叫鈑金加工。</p><div
