金剛石磨片是如何(he)造成的

金剛石磨(mo)片使用方面(mian)，根據不同的(de)(de)行業，不同的(de)(de)加工方法，不同的(de)(de)磨(mo)床會有許多不同的(de)(de)特點。在(zai)這(zhe)里我(wo)們撿取(qu)一些(xie)常見的(de)(de)問(wen)題(ti)進行講解。

1.由金剛石磨片龜裂產(chan)生的

問題一(yi)：金(jin)剛石(shi)磨片孔(kong)小或(huo)軸大時強硬裝(zhuang)入(ru)的(de)(de)場合(he)解決方法：金(jin)剛石(shi)磨片孔(kong)小或(huo)軸要(yao)能圓滑的(de)(de)裝(zhuang)入(ru)，而不能強硬裝(zhuang)入(ru)

問題二：一側(ce)使用法蘭盤(pan)

解決方(fang)法(fa)：金剛石磨片法(fa)蘭盤兩側大小(xiao)完全相同，均勻緊固

問題三：法蘭盤的支撐不均勻（法蘭盤彎曲；鉛灌孔層凸出；法蘭盤的毛刺；金剛石磨片不平）

解決方法：金剛(gang)石磨片法蘭盤左右兩(liang)側都要精加(jia)(jia)工成所規定的正(zheng)確且(qie)平滑的尺寸，金剛(gang)石磨片平面部分要地進行(xing)加(jia)(jia)工，同時(shi)鉛灌孔層不能平面凸出來。

使用金(jin)剛石軟(ruan)磨(mo)片有(you)如下(xia)優點

1)省電：金剛石磨塊(kuai)由于超鋒利性(xing)去磨削石材(cai)(cai)。由于磨頭(tou)的(de)(de)壓力可(ke)以(yi)大幅(fu)度下(xia)降，機械的(de)(de)磨損降低，同時加(jia)工同樣(yang)厚度的(de)(de)板材(cai)(cai)可(ke)以(yi)減(jian)少石材(cai)(cai)破損率，也(ye)可(ke)以(yi)加(jia)工較薄石材(cai)(cai)；

2)：金剛石磨塊由于鋒(feng)利性(xing)和耐(nai)磨性(xing)可以穩定地提高(gao)輸送帶的傳動速度，從而提高(gao)生產效(xiao)率；

3)光(guang)度(du)高：用(yong)金(jin)(jin)(jin)剛石(shi)(shi)磨(mo)塊(kuai)(kuai)(kuai)可以(yi)提(ti)高石(shi)(shi)材光(guang)度(du)10度(du)以(yi)上(shang)。金(jin)(jin)(jin)剛石(shi)(shi)磨(mo)塊(kuai)(kuai)(kuai)由(you)于采用(yong)的生產工藝可以(yi)完(wan)全避免如菱苦(ku)土磨(mo)塊(kuai)(kuai)(kuai)在生產過程中氧化(hua)鎂(mei)活性(xing)(xing)降(jiang)(jiang)低和(he)養護條件的變化(hua)使磨(mo)塊(kuai)(kuai)(kuai)的質(zhi)量不穩定；由(you)于金(jin)(jin)(jin)剛石(shi)(shi)生產和(he)檢(jian)測(ce)工藝和(he)運輸過程比碳(tan)化(hua)硅嚴格，金(jin)(jin)(jin)剛石(shi)(shi)的粒度(du)均勻性(xing)(xing)遠大于碳(tan)化(hua)硅，所以(yi)造(zao)成(cheng)石(shi)(shi)材劃痕和(he)光(guang)度(du)不穩定的可能性(xing)(xing)大大降(jiang)(jiang)低；

4)質量可靠：由于目前(qian)金剛(gang)石(shi)規(gui)模化生(sheng)(sheng)產(chan)，其(qi)價格(ge)已經大大下(xia)降，電鍍金剛(gang)石(shi)鉆(zhan)頭現貨供應，所以金剛(gang)石(shi)磨塊(kuai)的價格(ge)也大大下(xia)降，電鍍金剛(gang)石(shi)鉆(zhan)頭制作，另外由于金剛(gang)石(shi)磨片的生(sheng)(sheng)產(chan)可以采用計算機控(kong)制的生(sheng)(sheng)產(chan)設備和工藝(yi)，而菱苦土磨塊(kuai)的生(sheng)(sheng)產(chan)仍然采用簡(jian)單人(ren)工生(sheng)(sheng)產(chan)設備和工藝(yi)，并且(qie)生(sheng)(sheng)產(chan)周期長(chang)達一個(ge)月以上，影響質量的時間(jian)很長(chang)，質量不可能(neng)穩定。
