金瑞3A品質保證：

    ;   檢驗平板以高質量遠銷海(hai)內外。做(zuo)工精細，技術精湛(zhan)，出廠(chang)(chang)率極高。檢驗平板廠(chang)(chang)家(jia)直銷，我廠(chang)(chang)經濟(ji)實力雄厚，公司(si)廠(chang)(chang)房寬(kuan)大，設(she)備先進，購買熱(re)線：***。是用(yong)于(yu)工件檢測或劃線的平面基準(zhun)量具。

       檢(jian)(jian)(jian)驗(yan)(yan)(yan)平(ping)(ping)板(ban)(ban)在(zai)使用(yong)時(shi)要先(xian)進行安裝調試。然后，把檢(jian)(jian)(jian)驗(yan)(yan)(yan)平(ping)(ping)板(ban)(ban)的(de)工(gong)(gong)作面(mian)擦拭干(gan)凈，在(zai)確認沒有問(wen)題的(de)情況下使用(yong)，使用(yong)過程中(zhong)，要注意避免工(gong)(gong)件(jian)和(he)平(ping)(ping)板(ban)(ban)的(de)工(gong)(gong)作面(mian)過激的(de)碰撞(zhuang)，防止損(sun)壞(huai)(huai)檢(jian)(jian)(jian)驗(yan)(yan)(yan)平(ping)(ping)板(ban)(ban)的(de)工(gong)(gong)作面(mian)；工(gong)(gong)件(jian)的(de)重(zhong)量(liang)更不可以超過檢(jian)(jian)(jian)驗(yan)(yan)(yan)平(ping)(ping)板(ban)(ban)的(de)標(biao)準(zhun)載荷，否則會(hui)造成工(gong)(gong)作質量(liang)降低，還有可能損(sun)壞(huai)(huai)平(ping)(ping)板(ban)(ban)的(de)結構，甚至會(hui)造成平(ping)(ping)板(ban)(ban)變形損(sun)壞(huai)(huai)，無法使用(yong)。檢(jian)(jian)(jian)驗(yan)(yan)(yan)平(ping)(ping)板(ban)(ban)按JB/T3411.56-99標(biao)準(zhun)制(zhi)造，材料硬度(du)為HT200，廣泛(fan)用(yong)于工(gong)(gong)業(ye)制(zhi)造中(zhong)的(de)測(ce)量(liang)工(gong)(gong)作。檢(jian)(jian)(jian)驗(yan)(yan)(yan)平(ping)(ping)板(ban)(ban)用(yong)于工(gong)(gong)件(jian)及精密(mi)零部件(jian)的(de)劃線、研磨工(gong)(gong)藝加(jia)工(gong)(gong)和(he)測(ce)量(liang)，是檢(jian)(jian)(jian)驗(yan)(yan)(yan)機(ji)械零件(jian)平(ping)(ping)行度(du)和(he)直(zhi)線度(du)等形位(wei)偏差(cha)的(de)測(ce)量(liang)基準(zhun)。

       檢(jian)驗平(ping)臺(tai)(tai)適用(yong)于各種檢(jian)驗工(gong)作(zuo)(zuo)，精密(mi)測量用(yong)的(de)基準(zhun)平(ping)面(mian)；用(yong)于機床機械檢(jian)驗測量基準(zhun)；檢(jian)查零件的(de)尺寸精度或形為偏差，并作(zuo)(zuo)緊(jin)密(mi)劃線，在機械制造中也是(shi)不可缺少的(de)基本工(gong)具(ju)。檢(jian)驗平(ping)板(ban)精度：按國家標(biao)準(zhun)計量檢(jian)定規程執(zhi)行分別為0，1，2，3級四個級別。檢(jian)驗平(ping)臺(tai)(tai)工(gong)作(zuo)(zuo)面(mian)通常(chang)應采用(yong)刮(gua)削工(gong)藝。對采用(yong)刮(gua)削加(jia)工(gong)的(de)3級平(ping)板(ban)工(gong)作(zuo)(zuo)面(mian)，其表面(mian)粗(cu)糙度Ra最(zui)大允許值(zhi)為5μm。

       檢(jian)驗(yan)平(ping)(ping)(ping)(ping)臺安裝(zhuang)時要調(diao)整水(shui)平(ping)(ping)(ping)(ping)、使(shi)用時負(fu)荷均勻分(fen)布于(yu)(yu)各(ge)支點(dian)(dian)上，使(shi)用環(huan)境溫(wen)度（20±5）℃。檢(jian)驗(yan)平(ping)(ping)(ping)(ping)板(ban)表面(mian)(mian)(mian)質(zhi)量檢(jian)驗(yan)是用涂(tu)色法(fa)檢(jian)驗(yan)，其方(fang)法(fa)為0級(ji)1級(ji)平(ping)(ping)(ping)(ping)板(ban)在(zai)每邊為25毫米平(ping)(ping)(ping)(ping)方(fang)的范圍內不(bu)少(shao)(shao)于(yu)(yu)25點(dian)(dian)，2級(ji)不(bu)少(shao)(shao)于(yu)(yu)20點(dian)(dian)，3級(ji)不(bu)少(shao)(shao)于(yu)(yu)12點(dian)(dian)。檢(jian)驗(yan)平(ping)(ping)(ping)(ping)板(ban)按JB/T7974-1999標準制造，產品制成筋(jin)板(ban)式和(he)箱體式，工(gong)作面(mian)(mian)(mian)有長方(fang)形、正方(fang)形或圓(yuan)形，材料(liao)HT200-300，QT400-600，ZG15-45。工(gong)作面(mian)(mian)(mian)采用刮研工(gong)藝，工(gong)作面(mian)(mian)(mian)上可(ke)加工(gong)V形、T形、U形槽、燕尾槽、圓(yuan)孔、長孔等。
