今(jin)后適當(dang)長一段時間內，轎車(che)(che)工(gong)(gong)業(ye)將一向作為(wei)國民(min)經濟(ji)支(zhi)柱產業(ye)而取得較高速開(kai)展。轎車(che)(che)工(gong)(gong)業(ye)開(kai)展有賴(lai)轎車(che)(che)配(pei)備水平加工(gong)(gong)工(gong)(gong)藝水平進步，特別是(shi)機床數控化相應的(de)(de)加工(gong)(gong)東(dong)西(包含刃具、磨(mo)具)領先(xian)程(cheng)度。努(nu)力(li)開(kai)發轎車(che)(che)零部(bu)件加工(gong)(gong) 不可少的(de)(de)領先(xian)超硬資料刀具、磨(mo)具，是(shi)磨(mo)料磨(mo)具職業(ye)為(wei)習慣轎車(che)(che)工(gong)(gong)業(ye)開(kai)展促進本身開(kai)展的(de)(de)需求(qiu)。

　　對于中國轎車工業現(xian)狀(zhuang)，學習(xi)發(fa)(fa)達國家老(lao)練經歷，咱們應首(shou)要開發(fa)(fa)：加(jia)工活塞(sai)環用(yong)(yong)CBN磨(mo)盤(pan)；高(gao)精(jing)度高(gao)耐(nai)磨(mo)軸承加(jia)工用(yong)(yong)CBN砂輪(lun)(包含樹脂陶瓷(ci)結合劑)；各(ge)(ge)種(zhong)鑄鐵零部件(jian)加(jia)工用(yong)(yong)PCBN刀(dao)具磨(mo)具、珩磨(mo)東西；各(ge)(ge)種(zhong)液壓件(jian)加(jia)工用(yong)(yong)小(xiao)孔磨(mo)頭(tou)；轎車窗玻璃、轎車后視鏡等玻璃加(jia)工用(yong)(yong)各(ge)(ge)種(zhong)金(jin)剛石砂輪(lun)、套鉆；塑料、橡膠其它非(fei)金(jin)屬資料加(jia)工用(yong)(yong)金(jin)剛石磨(mo)輪(lun)；鋁合金(jin)件(jian)加(jia)工用(yong)(yong)CPD刀(dao)具；各(ge)(ge)種(zhong)用(yong)(yong)處(chu)金(jin)剛石修整滾輪(lun)等等。

　　這一范(fan)圍十分廣，應將要點依然放(fang)與(yu)基(ji)礎設施建(jian)造(zao)密(mi)切(qie)相關修建(jian)建(jian)材職業、路途交通設施等職業上。獨(du)自就資料而論，要點可放(fang)耐磨地磚(zhuan)、玻璃陶瓷等加工上。

陶(tao)瓷(ci)資(zi)(zi)料(liao)開(kai)展很快，由曩昔首要(yao)(yao)作為(wei)日子用(yong)材(cai)開(kai)展到工(gong)(gong)業用(yong)材(cai)、東(dong)西資(zi)(zi)料(liao)工(gong)(gong)程資(zi)(zi)料(liao)。陶(tao)瓷(ci)資(zi)(zi)料(liao)加工(gong)(gong)離不開(kai)金剛石。盡管中(zhong)國精(jing)細(xi)陶(tao)瓷(ci)使用(yong)還剛剛起步，依照開(kai)展趨勢(shi)，21世紀 將(jiang)取得廣泛使用(yong)，新資(zi)(zi)料(liao)工(gong)(gong)業重要(yao)(yao)成(cheng)員。因而要(yao)(yao)在(zai)日子陶(tao)瓷(ci)、電子陶(tao)瓷(ci)加工(gong)(gong)經(jing)歷基礎上(shang)，努力開(kai)發(fa)新金剛石加工(gong)(gong)東(dong)西，用(yong)于處理精(jing)細(xi)陶(tao)瓷(ci)加工(gong)(gong)疑(yi)問。
