一說到平面(mian)(mian)(mian)磨(mo)床(chuang)(chuang)機床(chuang)(chuang)人(ren)們就(jiu)以為(wei)是那種磨(mo)平的(de)機床(chuang)(chuang)。如今世(shi)界平面(mian)(mian)(mian)磨(mo)床(chuang)(chuang)的(de)發(fa)展趨(qu)勢已經變(bian)改變(bian)了。現(xian)在平面(mian)(mian)(mian)磨(mo)床(chuang)(chuang)發(fa)展趨(qu)勢是轉向成形、臺階、切入、快(kuai)速抖動(dong)、三(san)維空間曲線表面(mian)(mian)(mian)磨(mo)削加工。可以說，平磨(mo)是磨(mo)床(chuang)(chuang)機床(chuang)(chuang)中演變(bian)潛力大的(de)一種機型(xing)。

不同的(de)平(ping)(ping)面磨(mo)床設備在(zai)不斷(duan)的(de)使(shi)用當(dang)中(zhong)(zhong)會(hui)出現很多的(de)問題(ti)，于是伴隨問題(ti)的(de)解決(jue)，產品也在(zai)不斷(duan)的(de)升級改(gai)造(zao)當(dang)中(zhong)(zhong)，在(zai)我國的(de)大(da)(da)型零(ling)件加工(gong)(gong)(gong)(gong)當(dang)中(zhong)(zhong)，平(ping)(ping)磨(mo)是磨(mo)床類機(ji)床中(zhong)(zhong)演變潛力Z 大(da)(da)的(de)一種機(ji)型。為了保證平(ping)(ping)面磨(mo)床在(zai)正常的(de)工(gong)(gong)(gong)(gong)作當(dang)中(zhong)(zhong)可以(yi)更好的(de)完成工(gong)(gong)(gong)(gong)作，于是對于操(cao)作工(gong)(gong)(gong)(gong)人來說，使(shi)用平(ping)(ping)面磨(mo)床需要注(zhu)意很多的(de)問題(ti)。

1、墊彈性墊片裝夾方式

平(ping)面(mian)磨(mo)(mo)床上磨(mo)(mo)削(xue)上述薄片工(gong)(gong)(gong)件時，采用彈性(xing)夾緊機構，使薄片工(gong)(gong)(gong)件在(zai)自由狀(zhuang)態下實現定位與夾緊。在(zai)工(gong)(gong)(gong)件與磁性(xing)工(gong)(gong)(gong)作臺之間墊(dian)一(yi)層0.5mm厚的橡膠(jiao)，當(dang)工(gong)(gong)(gong)件受(shou)磁性(xing)吸引力作用時，橡膠(jiao)被壓(ya)縮(suo)，彈性(xing)變(bian)形變(bian)小，從而可(ke)磨(mo)(mo)削(xue)出工(gong)(gong)(gong)件的平(ping)直平(ping)面(mian)。反(fan)復磨(mo)(mo)削(xue)幾次，可(ke)滿足加工(gong)(gong)(gong)精度要(yao)求(qiu)。

2、用臨時措施加強薄片工件的剛性

采用環(huan)氧樹脂結(jie)(jie)合劑，將(jiang)薄(bo)(bo)片(pian)(pian)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)在自由狀態下粘到一(yi)塊平板(ban)(ban)(ban)上。平板(ban)(ban)(ban)連同(tong)薄(bo)(bo)片(pian)(pian)一(yi)起放到磁力(li)吸盤(pan)上。磨(mo)(mo)平薄(bo)(bo)片(pian)(pian)一(yi)端(duan)平面(mian)(mian)后(hou)，再將(jiang)薄(bo)(bo)片(pian)(pian)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)從(cong)平板(ban)(ban)(ban)上取下來，以磨(mo)(mo)平的(de)一(yi)面(mian)(mian)放到磁力(li)吸盤(pan)上，再磨(mo)(mo)削(xue)薄(bo)(bo)片(pian)(pian)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)的(de)另一(yi)端(duan)平面(mian)(mian)。由于環(huan)氧樹脂在未硬化之前有流(liu)動性(xing)，它可(ke)以填平薄(bo)(bo)片(pian)(pian)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)與平板(ban)(ban)(ban)之間(jian)(jian)的(de)間(jian)(jian)隙。當環(huan)氧樹脂硬化后(hou)，工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)與平板(ban)(ban)(ban)粘結(jie)(jie)在一(yi)起，成為一(yi)個整體，從(cong)而大(da)大(da)增(zeng)強了工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)的(de)剛性(xing)。在磁力(li)吸引(yin)下，薄(bo)(bo)片(pian)(pian)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)不會(hui)產生夾緊變形，為磨(mo)(mo)削(xue)出(chu)平直平面(mian)(mian)創(chuang)造了條件(jian)(jian)(jian)。也可(ke)用厚油脂代替環(huan)氧樹脂填充薄(bo)(bo)片(pian)(pian)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)與磁力(li)吸盤(pan)之間(jian)(jian)的(de)間(jian)(jian)隙，增(zeng)強工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)的(de)剛性(xing)，同(tong)樣可(ke)以收到良好的(de)效果。

3、真空裝夾方式

利用(yong)大氣的(de)壓(ya)力(li)裝夾薄片工(gong)(gong)件來進行磨削加(jia)工(gong)(gong)。其工(gong)(gong)作原(yuan)理為：夾具體(ti)上設有(you)橡膠密封(feng)圈(quan)(quan)，把薄片工(gong)(gong)件放(fang)在橡膠密封(feng)圈(quan)(quan)上，從(cong)而使工(gong)(gong)件與夾具體(ti)之間形成密封(feng)腔。用(yong)真空泵將室內空氣從(cong)抽氣孔抽出，這時工(gong)(gong)件被夾緊。由于(yu)夾緊力(li)小，可采用(yong)圓周磨削方法進行磨削加(jia)工(gong)(gong)。當磨削好薄片工(gong)(gong)件一端(duan)平(ping)面后(hou)，磨削薄片工(gong)(gong)件另一端(duan)平(ping)面時，可采用(yong)上述(shu)方式進行，同樣(yang)可得(de)到滿意的(de)結果。
