　板件砂光常采用長帶砂光機和(he)寬帶(dai)(dai)(dai)砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)光(guang)(guang)機。長(chang)帶(dai)(dai)(dai)砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)光(guang)(guang)機又可分為帶(dai)(dai)(dai)滑動(dong)(dong)工(gong)(gong)(gong)(gong)作(zuo)(zuo)臺及手(shou)控壓(ya)(ya)塊(kuai)(kuai)的(de)(de)長(chang)帶(dai)(dai)(dai)砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)光(guang)(guang)機和(he)帶(dai)(dai)(dai)加壓(ya)(ya)塊(kuai)(kuai)與毛(mao)氈肋條(tiao)帶(dai)(dai)(dai)的(de)(de)長(chang)帶(dai)(dai)(dai)砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)光(guang)(guang)機。前者的(de)(de)砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)光(guang)(guang)工(gong)(gong)(gong)(gong)件可在(zai)(zai)(zai)帶(dai)(dai)(dai)導軌的(de)(de)工(gong)(gong)(gong)(gong)作(zuo)(zuo)臺上(shang)移(yi)動(dong)(dong),手(shou)持(chi)操(cao)(cao)作(zuo)(zuo)桿對壓(ya)(ya)塊(kuai)(kuai)施壓(ya)(ya),砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)帶(dai)(dai)(dai)在(zai)(zai)(zai)壓(ya)(ya)塊(kuai)(kuai)的(de)(de)作(zuo)(zuo)用(yong)(yong)下對工(gong)(gong)(gong)(gong)件砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)磨,這種砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)光(guang)(guang)機結構簡單(dan),投資費用(yong)(yong)低(di),可對大(da)規格的(de)(de)實木(mu)(mu)板或人造(zao)板貼木(mu)(mu)皮的(de)(de)部件進行砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)光(guang)(guang),在(zai)(zai)(zai)熟練工(gong)(gong)(gong)(gong)的(de)(de)操(cao)(cao)作(zuo)(zuo)下,可獲得較(jiao)好(hao)的(de)(de)表(biao)面(mian)砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)光(guang)(guang)效果(guo)。它用(yong)(yong)氣動(dong)(dong)加壓(ya)(ya)墊代替了(le)(le)切(qie)削(xue)方(fang)向移(yi)動(dong)(dong)的(de)(de)手(shou)控壓(ya)(ya)板,加壓(ya)(ya)墊覆蓋整個工(gong)(gong)(gong)(gong)件寬度,但(dan)當(dang)砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)帶(dai)(dai)(dai)與工(gong)(gong)(gong)(gong)件接觸面(mian)過大(da)時(shi),增加了(le)(le)動(dong)(dong)力消耗(hao),而且砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)光(guang)(guang)時(shi)大(da)量(liang)木(mu)(mu)屑易粘附(fu)在(zai)(zai)(zai)砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)帶(dai)(dai)(dai)上(shang)，同時(shi)砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)帶(dai)(dai)(dai)易發熱，從而縮短(duan)了(le)(le)砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)帶(dai)(dai)(dai)使用(yong)(yong)壽命，設置的(de)(de)毛(mao)氈肋條(tiao)帶(dai)(dai)(dai)，可克服上(shang)述缺陷，提高砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)光(guang)(guang)質量(liang)。還有(you)(you)一種多軸(zhou)壓(ya)(ya)塊(kuai)(kuai)式長(chang)帶(dai)(dai)(dai)砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)光(guang)(guang)機，它適用(yong)(yong)于(yu)空(kong)心板件的(de)(de)砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)光(guang)(guang),即使空(kong)心板件表(biao)面(mian)有(you)(you)輕微不(bu)平時(shi)也可獲得較(jiao)好(hao)的(de)(de)砂(sha)(sha)(sha)(sha)(sha)(sha)(sha)光(guang)(guang)效果(guo)。
