金剛石磨輪石墨模具發(fa)展背景(jing)

  工(gong)(gong)(gong)(gong)具(ju)(ju)，是人(ren)(ren)類能(neng)力的(de)(de)(de)延伸，是推(tui)動(dong)社會發展(zhan)(zhan)進步的(de)(de)(de)杠桿。在人(ren)(ren)類發展(zhan)(zhan)史(shi)上工(gong)(gong)(gong)(gong)具(ju)(ju)起著(zhu)不可替代(dai)的(de)(de)(de)作用(yong)(yong)(yong)，并且(qie)隨著(zhu)高效(xiao)(xiao)(xiao)率、高精度的(de)(de)(de)工(gong)(gong)(gong)(gong)作要求，對工(gong)(gong)(gong)(gong)具(ju)(ju)的(de)(de)(de)生產(chan)技術要求越(yue)來(lai)越(yue)高。50年前人(ren)(ren)們(men)在苦苦尋求如(ru)何改變硬(ying)(ying)脆材料(liao)加(jia)(jia)工(gong)(gong)(gong)(gong)業艱辛而又效(xiao)(xiao)(xiao)率低下(xia)勞動(dong)狀態，直(zhi)到1955 年人(ren)(ren)造金(jin)(jin)(jin)(jin)剛(gang)石*次在美(mei)國合(he)成(cheng)(cheng)成(cheng)(cheng)功(gong)，為(wei)金(jin)(jin)(jin)(jin)剛(gang)石工(gong)(gong)(gong)(gong)具(ju)(ju)的(de)(de)(de)制(zhi)造及推(tui)廣奠定了基礎，同(tong)時也為(wei)許(xu)多艱難的(de)(de)(de)硬(ying)(ying)脆非金(jin)(jin)(jin)(jin)屬材料(liao)加(jia)(jia)工(gong)(gong)(gong)(gong)業帶來(lai)了曙光(guang)，成(cheng)(cheng)為(wei)人(ren)(ren)類史(shi)上的(de)(de)(de)一次劃(hua)時代(dai)的(de)(de)(de)工(gong)(gong)(gong)(gong)具(ju)(ju)革命(ming)，其(qi)(qi)(qi)加(jia)(jia)工(gong)(gong)(gong)(gong)效(xiao)(xiao)(xiao)率明顯(xian)地(di)高于以(yi)往(wang)，金(jin)(jin)(jin)(jin)剛(gang)石工(gong)(gong)(gong)(gong)具(ju)(ju)以(yi)其(qi)(qi)(qi)無與倫比(bi)的(de)(de)(de)性能(neng)優勢，成(cheng)(cheng)為(wei)當今(jin)公認(ren)的(de)(de)(de)、*有效(xiao)(xiao)(xiao)的(de)(de)(de)硬(ying)(ying)脆非金(jin)(jin)(jin)(jin)屬材料(liao)加(jia)(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)具(ju)(ju)，比(bi)如(ru)，只有用(yong)(yong)(yong)金(jin)(jin)(jin)(jin)剛(gang)石刀(dao)具(ju)(ju)能(neng)加(jia)(jia)工(gong)(gong)(gong)(gong)超(chao)硬(ying)(ying)的(de)(de)(de)陶瓷，尚無其(qi)(qi)(qi)他(ta)代(dai)用(yong)(yong)(yong)品。金(jin)(jin)(jin)(jin)剛(gang)石砂輪用(yong)(yong)(yong)來(lai)磨削(xue)硬(ying)(ying)質(zhi)(zhi)合(he)金(jin)(jin)(jin)(jin)，比(bi)碳化(hua)硅耐用(yong)(yong)(yong)一萬倍(bei)。用(yong)(yong)(yong)金(jin)(jin)(jin)(jin)剛(gang)石磨料(liao)代(dai)替碳化(hua)硅磨料(liao)加(jia)(jia)工(gong)(gong)(gong)(gong)光(guang)學玻璃(li)，生產(chan)效(xiao)(xiao)(xiao)率可以(yi)提(ti)高數倍(bei)至數十倍(bei)。金(jin)(jin)(jin)(jin)剛(gang)石聚晶(jing)拉(la)絲模(mo)比(bi)用(yong)(yong)(yong)硬(ying)(ying)質(zhi)(zhi)合(he)金(jin)(jin)(jin)(jin)的(de)(de)(de)拉(la)絲模(mo)的(de)(de)(de)使用(yong)(yong)(yong)壽命(ming)長250 倍(bei)。

隨(sui)著(zhu)我(wo)國經濟(ji)的(de)不斷(duan)發展，金(jin)剛石工(gong)具不僅被廣(guang)泛用于民(min)用建筑與土木(mu)工(gong)程、石材(cai)金(jin)剛石工(gong)具

   加工業、汽車(che)工業、交通工業、地勘(kan)與國(guo)防(fang)工業等領域和其它現(xian)(xian)代高(gao)新技術領域，而且(qie)在(zai)寶石(shi)、醫療器(qi)械、木材(cai)、玻璃鋼、石(shi)材(cai)工藝品(pin)、陶瓷和復合非(fei)金(jin)屬硬脆材(cai)料等眾多新領域不斷出現(xian)(xian)，社會對金(jin)剛石(shi)工具(ju)的(de)需求量正在(zai)逐(zhu)年大幅增加。

就產品定(ding)位而言，金(jin)剛(gang)石(shi)(shi)工具(ju)市(shi)(shi)(shi)(shi)場(chang)(chang)大體上分(fen)為*市(shi)(shi)(shi)(shi)場(chang)(chang)和通用市(shi)(shi)(shi)(shi)場(chang)(chang)。*市(shi)(shi)(shi)(shi)場(chang)(chang)對金(jin)剛(gang)石(shi)(shi)工具(ju)的(de)(de)要(yao)求主要(yao)體現在(zai)對性能指標要(yao)求較高，即針對特定(ding)切(qie)割(ge)設備(bei)、特定(ding)切(qie)割(ge)材(cai)料，要(yao)求金(jin)剛(gang)石(shi)(shi)工具(ju)必須滿(man)足一(yi)定(ding)切(qie)割(ge)效率、切(qie)割(ge)壽(shou)命和加工精(jing)度等技術(shu)指標。*金(jin)剛(gang)石(shi)(shi)工具(ju)就其產量(liang)來說僅為金(jin)剛(gang)石(shi)(shi)工具(ju)產品總量(liang)的(de)(de)10%左右(you)，但其市(shi)(shi)(shi)(shi)場(chang)(chang)銷(xiao)售額卻占金(jin)剛(gang)石(shi)(shi)工具(ju)市(shi)(shi)(shi)(shi)場(chang)(chang)總額的(de)(de)80%～90%。

   20 世紀(ji)60 年代(dai)，金(jin)剛(gang)石(shi)(shi)工(gong)具制(zhi)造(zao)業率先(xian)在(zai)歐(ou)美(mei)發(fa)達*實現(xian)產業化并迅(xun)速(su)(su)發(fa)展。70 年代(dai)，日本以其相(xiang)對較低的制(zhi)造(zao)成本贏得競爭優(you)勢，迅(xun)速(su)(su)成為(wei)金(jin)剛(gang)石(shi)(shi)工(gong)具制(zhi)造(zao)業的主導者之一。80 年代(dai)，韓(han)國(guo)(guo)替代(dai)日本成為(wei)金(jin)剛(gang)石(shi)(shi)工(gong)具產業的后(hou)(hou)起(qi)(qi)之秀。90 年代(dai)，伴隨著(zhu)中國(guo)(guo)制(zhi)造(zao)產業在(zai)*的崛(jue)起(qi)(qi)，中國(guo)(guo)金(jin)剛(gang)石(shi)(shi)工(gong)具制(zhi)造(zao)業也開(kai)始起(qi)(qi)步，并逐(zhu)漸顯示出強(qiang)大競爭力，經過十(shi)多年的發(fa)展，中國(guo)(guo)已(yi)有金(jin)剛(gang)石(shi)(shi)工(gong)具生(sheng)產廠家上千家，年產值超過百億元(yuan)，已(yi)成為(wei)繼(ji)韓(han)國(guo)(guo)之后(hou)(hou)目前(qian)*金(jin)剛(gang)石(shi)(shi)工(gong)具市場的主要供應(ying)國(guo)(guo)之一。

隨著中(zhong)國(guo)在金剛(gang)(gang)石(shi)工(gong)具(ju)制造(zao)(zao)業(ye)上的(de)(de)(de)技術積累與進步(bu)，中(zhong)國(guo)金剛(gang)(gang)石(shi)工(gong)具(ju)企業(ye)目前已*具(ju)備制造(zao)(zao)中(zhong)*金剛(gang)(gang)石(shi)工(gong)具(ju)的(de)(de)(de)能力，并具(ju)有顯著的(de)(de)(de)產品性(xing)價比(bi)優(you)勢(shi)，西方*以往(wang)在中(zhong)高(gao)端(duan)(duan)*市場(chang)的(de)(de)(de)技術壟(long)斷已經被打破。中(zhong)國(guo)金剛(gang)(gang)石(shi)工(gong)具(ju)企業(ye)進軍中(zhong)高(gao)端(duan)(duan)市場(chang)的(de)(de)(de)趨勢(shi)已經顯現。

   就產(chan)(chan)品(pin)類型而言，中(zhong)國(guo)金(jin)(jin)(jin)剛(gang)石(shi)工具企(qi)業(ye)主要生產(chan)(chan)：金(jin)(jin)(jin)剛(gang)石(shi)鋸片(pian)(pian)、金(jin)(jin)(jin)剛(gang)石(shi)鉆頭、金(jin)(jin)(jin)剛(gang)石(shi)碗磨和金(jin)(jin)(jin)剛(gang)石(shi)刀具、金(jin)(jin)(jin)剛(gang)石(shi)、金(jin)(jin)(jin)剛(gang)石(shi)樹脂磨塊等幾類產(chan)(chan)品(pin)。其(qi)中(zhong)，金(jin)(jin)(jin)剛(gang)石(shi)鋸片(pian)(pian)是我國(guo)金(jin)(jin)(jin)剛(gang)石(shi)工具企(qi)業(ye)產(chan)(chan)量(liang)*大的品(pin)種。
