剪(jian)板(ban)(ban)(ban)(ban)機(ji)(ji)是借于運動(dong)的(de)上刀(dao)片(pian)和固定的(de)下刀(dao)片(pian)，采用(yong)合(he)理(li)的(de)刀(dao)片(pian)間隙，對各(ge)種(zhong)厚(hou)度(du)的(de)金屬板(ban)(ban)(ban)(ban)材施加(jia)剪(jian)切力，使板(ban)(ban)(ban)(ban)材按所需(xu)要的(de)尺(chi)寸(cun)斷裂(lie)分(fen)離。剪(jian)板(ban)(ban)(ban)(ban)機(ji)(ji)可(ke)分(fen)為：腳踏式(shi)（人(ren)力）、機(ji)(ji)械剪(jian)板(ban)(ban)(ban)(ban)機(ji)(ji)式(shi)、液壓擺式(shi)剪(jian)板(ban)(ban)(ban)(ban)機(ji)(ji)等(deng)。剪(jian)板(ban)(ban)(ban)(ban)機(ji)(ji)常(chang)用(yong)來(lai)剪(jian)裁直(zhi)線邊(bian)緣的(de)板(ban)(ban)(ban)(ban)料毛坯。剪(jian)切工(gong)藝應能保證(zheng)被(bei)剪(jian)板(ban)(ban)(ban)(ban)料剪(jian)切表面的(de)直(zhi)線性和平行度(du)要求，并盡(jin)量(liang)減少板(ban)(ban)(ban)(ban)材扭曲，以獲(huo)得高質(zhi)量(liang)的(de)工(gong)件。

剪板(ban)(ban)機工(gong)(gong)作前，刀片(pian)的(de)刃口(kou)必須保持(chi)(chi)銳(rui)利，如刃口(kou)變鈍或有崩裂現象，應及時磨利或更換。刀板(ban)(ban)應緊固牢靠，刀片(pian)必須緊貼，上(shang)、下刀板(ban)(ban)面保持(chi)(chi)平行(xing)，調正后應用人(ren)工(gong)(gong)盤(pan)車檢(jian)驗，以(yi)免發(fa)生意外。其刀片(pian)間(jian)(jian)隙(xi)應根據剪切鋼板(ban)(ban)厚度確定，一般為被剪板(ban)(ban)料的(de)厚度5~7%之間(jian)(jian)，每次間(jian)(jian)隙(xi)調整都應用手轉動飛輪，使上(shang)下刀片(pian)往復(fu)運動一次，并用輔助測量工(gong)(gong)具檢(jian)查間(jian)(jian)隙(xi)是否合適(shi)，防止彈(dan)簧(huang)崩斷或損傷刃口(kou)。

剪(jian)板機(ji)送(song)料(liao)(liao)要(yao)正、平、穩。手(shou)指(zhi)(zhi)不(bu)得(de)接(jie)近切刀和壓板，送(song)料(liao)(liao)時(shi)要(yao)注意手(shou)指(zhi)(zhi)安(an)全、特別是(shi)一張板料(liao)(liao)剪(jian)到末了時(shi)、不(bu)要(yao)將手(shou)指(zhi)(zhi)墊在(zai)板料(liao)(liao)下送(song)料(liao)(liao)或(huo)將手(shou)指(zhi)(zhi)送(song)入刃口。料(liao)(liao)頭不(bu)夠200mm不(bu)準手(shou)動(dong)剪(jian)切，應選折輔助(zhu)工(gong)具(ju)進(jin)行剪(jian)切。應在(zai)剪(jian)扳機(ji)上(shang)安(an)置防護(hu)柵(zha)欄，防止操(cao)作(zuo)者(zhe)的(de)手(shou)進(jin)入剪(jian)刀落下區域內，防護(hu)柵(zha)欄不(bu)能擋住操(cao)作(zuo)者(zhe)眼睛而看(kan)不(bu)到裁切的(de)部位。工(gong)作(zuo)時(shi)嚴禁撿拾地上(shang)廢(fei)(fei)料(liao)(liao)，以免被落下來的(de)工(gong)件擊傷。作(zuo)業(ye)后(hou)產生的(de)廢(fei)(fei)料(liao)(liao)有棱(leng)有角，操(cao)作(zuo)者(zhe)應及(ji)時(shi)清除，防止被刺傷、割傷。

剪板機的皮帶、飛輪、齒輪以及軸等運動部位必須安裝防護罩。要經常注意夾緊機構及離合器、制動器有無異常失靈現象；剪切時應精力集中，若發現設備有異常現象，應立即停止剪切，切斷電源，通知有關人員檢修。確保安全生產，提高工作效率，發生人身設備事故，應保持現場，并報告有關部門工作完畢下班前，應切斷電源，擦凈設備，做好點檢記錄。
