Chii chinonzi PCD saw blade?

Kuona kuti vanhu vakawanda havazivi zvakawanda pamusoro pekutsanangurwa kwePCD saw blade, kunyange kusanganisira vashandi vane chokuita nePCD saw blade, tsanangudzo yakapiwa nevamwe vavo haina kukwana zvakakwana!

Zita rakazara reChinese rePCD saw blade ndiko kudimburirwa kwe "polycrystalline diamond saw blade", umo PCD iri chidimbu chePolyCrystalline Diamond (yakaturikirwa muchiChinese ichinzi polycrystalline diamond), saka PCD saw blade inodaidzwa zvakare kuti diamond. Saw blade, asi nekuti blade yedhaimani yekucheka ibwe yakaonekwa kare kupfuura PCD saw blade, Huangrui Tool anotenda kuti zviri nyore kukonzera nyonganiso kungodaidza PCD saw blade sedhaimani. Hazvina kunyanya kunzwisiswa kudana iyo PCD diamond saw blade.
Sezvatinoziva tese, dhaimondi ndicho chinhu chakaomesesa chiripo muzvisikwa. Iyo yenguva dzose octahedral single crystal inoumbwa nekabhoni zvinhu zvakaumbwa munzvimbo yakadzika yepasi pasi pekuita kwekumanikidza kwakanyanya uye kupisa kwakanyanya. Yakasimba, maerekitironi ose evalence anobatanidzwa mukuumbwa kwezvisungo zve covalent, hapana maerekitironi akasununguka aripo, saka kuoma kwedhaimondi kwakakura kwazvo, kuoma kwedhaimondi kakapetwa ka4 kune corundum uye 8 nguva yequartz!

Tekinoroji yemazuva ano yagara ichikwanisa kugadzira madhaimondi ega makristasi, uye PCD inoshandisa cobalt nedzimwe simbi semabhindari kuti polycrystallize synthetic diamond imwe crystal poda kuita diamond polycrystals pasi pemamiriro chaiwo. Kuoma kweiyi polycrystalline diamond (kureva PCD) ndiko Kunyange zvazvo isina kuoma sedhaimondi rimwe chete rekristaro, kuoma kuchiri kukwira se8000HV, iyo iri 80 ~ 120 nguva yesamende carbide! Uyezve, iyo yekupisa conductivity yakatevedzana yePCD ndeye 700W/MK, inova 2 ~ 9 nguva yeiyo simende carbide, uye kunyange yakakwirira kupfuura iyo yePCBN nemhangura. Naizvozvo, uchishandisa PCB zvinhu senge yesaha blade musoro, kupisa kwekushisa kunomhanya zvakanyanya panguva yekucheka. Mukuwedzera, iyo coefficient yekuwedzera kwekushisa kwePCD zvinhu inongova chikamu chimwe chete chechishanu cheiyo cemented carbide, uye coefficient of friction inongova chikamu chimwe chete muzvitatu cheiyo cemented carbide. Izvi zvivakwa zvinotarisa kuti blade yesaha inoshandisa PCD zvinhu sezvo musoro wekucheka wakaenzana nemuviri wesaha. Pasi pemamwe mamiriro ezvinhu, kwete chete hupenyu hwebasa resaha blade inotepfenyura kanenge 30 yakakwira kupfuura iyo yecarbide saw blade, asiwo kunaka kwenzvimbo yekucheka kuri nani. Uyezve, hukama huri pakati pePCD zvinhu uye simbi dzisina-ferrous uye zvisiri-simbi zvinhu idiki. Paunenge uchicheka simbi dzisina-ferrous kana zvisiri-metal zvinhu, PCD cutter musoro pane saha blade zvakare kashoma kusungira sawdust kupfuura iyo carbide cutter head. Pakupedzisira, pane imwe mukana: PCD zvinhu zvine asidhi yakasimba uye alkali kuramba kugadzikana, iyo inobatsirawo zvakanyanya kugadzikana kwemhando yePCD saw blades.

Iyo PCD saw blade ndeye kushandisa simende carbide sematrix yePCD zvinhu zvinodarika 1mm, kuumba musanganiswa kuburikidza nekuisa kana mamwe maitiro ekutsikirira, uye pakupedzisira inlay pane alloy simbi ndiro muviri wesaha, kuitira kutsiva. iyo yakaoma zvinhu ine PCD cutter musoro. Ndiyo chidimbu chekucheka chejecha, iyo inovandudza zvikuru hupenyu hwebasa resaha uye kugadzikana kwehutano hwekucheka.

Parizvino, vanonyanya kushandisa saha blade vashandisi vanosarudza kushandisa PCD madhaimani saw blades ane Ultra-yakareba sevhisi hupenyu, ayo anonyanya kushandiswa muindasitiri yekugadzira fenicha, isiri-ferrous simbi yekugadzirisa indasitiri yakaoma kucheka, uye aruminiyamu alloy gonhi nehwindo. vagadziri kutsiva mapanga ekutanga ecarbide. Iyo alloy saw blade yemusoro haigone kungocheka nguva dzose kwenguva yakareba, asiwo haidi kutsiva saha blade kazhinji. Hupenyu hurefu, huzere, hunoderedza yakawanda yekucheka mitengo kana ichienzaniswa nekushandiswa kwecarbide saw blades!
