CBN vs. PCD: Le Taua a Superhard Cutting Tools - O se Maulu loloto i Gaosi ma Fa'atinoga
CBN (Cubic Boron Nitride) CNC Meafaigaluega tipi
CBN, poʻo le Cubic Boron Nitride, o se mea faʻapipiʻi e iloa ona o lona maaa tele ma le tumau. E lona lua na'o taimane i tulaga o le maaa, lea e avea ai ma mea lelei mo le tipiina o meafaigaluega faʻaaogaina i masini maualuga. O meafaigaluega tipi CBN e masani ona faʻaaogaina mo le faʻaogaina o uʻamea malo, uʻamea, ma isi mea e sili atu le malosi e faigata ona faʻaogaina i meafaigaluega tipi masani.
Fa'agasologa o le Gaosiina ole CBN Tools:
O le gaosiga o meafaigaluega tipi CBN e masani ona aofia ai le tuʻufaʻatasia o le boron nitride (BN) i lalo o le mamafa ma le vevela maualuga. O le faagasologa e amata i le boron powder ma le nitrogen gas, lea e oʻo i tulaga ogaoga (i luga aʻe o le 1500°C) e fausia ai tioata boron nitride (c-BN). O nei tioata e tuʻufaʻatasia ma se mea matrix, e masani lava o se faʻapipiʻi cobalt, e fai ai se mea faʻapipiʻi tipi poʻo se meafaigaluega. O lenei tu'ufa'atasiga e tu'uina atu ai le meafaigaluega a le CBN ma lona ma'a'a mata'ina ma le fa'alavalava.
CBN faʻapipiʻi e mafai ona gaosia i foliga eseese ma lapopoa, faʻalagolago i manaoga faʻapitoa o masini. O le mea faigaluega mulimuli e masani ona fa'apalapala, eleele, ma faʻapipiʻiina e faʻaleleia atili ai lona faʻatinoga ma le maeʻa. Ole malosi ole mea faigaluega e fa'atumauina ai pito ma'ai ma'ai ile vevela maualuga e avea ma filifiliga sili mo galuega mamafa-tiute i alamanuia e pei ole vateatea, ta'avale, ma mea faigaluega gaosiga.
PCD (Polycrystalline Diamond) Meafaigaluega tipi CNC
PCD, poʻo le Polycrystalline Diamond, o se mea e faia e ala i le faʻapipiʻiina o tioata taimane lelei i lalo o le mamafa ma le vevela, e maua ai se mea faigaluega tipi malosi ma umi. O mea faigaluega PCD e lauiloa ona o lo latou fa'aofuofu fa'apitoa, aemaise lava pe'a fa'aogaina metala e le o ni u'amea pei o le alumini, kopa, ma le 'apamemea, fa'apea fo'i ma mea fa'apipi'i.
Fa'agasologa o le Gausia o Meafaigaluega PCD:
O le gaosiga o mea faigaluega PCD e amata i le fausiaina o pauta taimane lelei, lea e faʻafefiloi ma se fusi uʻamea, e masani lava o le cobalt poʻo isi pauta uʻamea. O lenei faʻafefiloi e faʻapipiʻiina i se faiga maualuga-vevela, maualuga-omiga e taʻua o le "sintering" i totonu o se lomitusi faapitoa. I le faagasologa o lenei faagasologa, o tioata taimane e fusi faatasi, ma fausia ai se fausaga mafiafia, polycrystalline.
O meafaigaluega PCD e masani ona gaosia i ni faiga autu se lua: monolithic ma brazed. I le auala monolithic, o le meafaigaluega atoa e faia mai le PCD, aʻo i le auala faʻapipiʻi, o se mea manifinifi o le PCD o loʻo faʻapipiʻiina i se mea faʻapipiʻi carbide. A maeʻa le faʻamaʻaina, o mea faigaluega PCD e faʻapalapala ma faʻamalo i fua saʻo, faʻamautinoa le tipiina o pito ma le lamolemole. E mafai ona toe togafitia i latou i paʻu e faʻateleina ai lo latou teteʻe i le ofuina ma le faʻamaʻiina, lea e mafai ona faʻaleleia atili ai a latou faʻatinoga i faʻaoga faʻapitoa.
O mea faigaluega PCD e masani ona faʻaaogaina mo galuega faʻapipiʻi saʻo maualuga ma e sili ona aoga mo le faʻaogaina o mea e mafua ai le ofuina o mea faigaluega masani. Ona o lo latou ma'a'a ma'a'a fa'apitoa ma le maualalo o fe'ese'esea'iga, latou te maua ai le fa'atinoga mata'ina i le fa'amae'aina ma le fa'agaio'iga fa'avavevave.

Eseesega Autu:
Mea Fesootaiga:
O le CBN e fetaui lelei mo mea malo ma abrasive e pei o u'amea malo ma u'amea.
O le PCD e lelei mo mea vaivai e pei o le alumini, kopa, ma mea tuʻufaʻatasia, lea e masani ona faʻaumatia meafaigaluega masani.
Fa'atinoga i le maualuga o le vevela:
O meafaigaluega a le CBN e mafai ona tatalia le maualuga o le vevela e aunoa ma le faʻaleagaina, e sili atu le aoga mo tulaga maualuga ma le vevela vevela.
O mea faigaluega PCD, e ui ina faigata tele, e itiiti le fa'apalepale i le maualuga o le vevela ma e mafai ona leiloa o latou mata i lalo o ia tulaga.
Iloiloga o Tau:
O meafaigaluega a le CBN e foliga mai e sili atu le taugofie nai lo mea faigaluega PCD, aua e manaʻomia e le PCD le faʻalavelave faʻagasologa o gaosiga ma o meafaitino lava ia e sili atu le taugata.
Fa'ai'uga ma le Sa'o:
O mea faigaluega PCD e sili atu ona fetaui mo le ausiaina o mea sili ona lelei, aemaise lava i mea e le o ni ferrous.
O meafaigaluega a le CBN, e ui ina sa'o, e sili atu i le tumau ma le tipiina o le malosi nai lo le ausiaina o le maualuga maualuga i luga o mea i mea vaivai.
O CBN ma PCD CNC meafaigaluega tipi e ofoina atu le faʻatinoga faʻapitoa, ae latou te faʻafeiloaʻi i manaoga eseese o masini. O mea faigaluega a le CBN e lelei mo mea faigata, faigata ma faʻaoga maualuga-vevela, aʻo susulu meafaigaluega a le PCD pe a galue i uʻamea vaivai ma mea tuʻufaʻatasia, e maua ai le ola umi o meafaigaluega ma le lelei o le tipiina. Filifilia i le va o le lua e faʻalagolago i mea faʻapitoa o loʻo faʻaaogaina, le manaʻomia o meafaigaluega, ma le siosiomaga masini.
