Idayimani yePolycrystalline (PCD) Izixhobo zokusika

Polycrystalline Diamond (PCD) Cutting Tools

Ukuphuhliswa kwezixhobo zokusika zePCD

Idayimani njengesixhobo esinzima kakhulu sisetyenziselwa ukusika, enembali yamakhulu eminyaka. Kwinkqubo yophuhliso lwezixhobo zokusika ukusuka ekupheleni kwekhulu le-19 ukuya phakathi kwekhulu lama-20, izixhobo zesixhobo zazibonakaliswa ikakhulu ngentsimbi ephezulu. Ngomnyaka we-1927, iJamani yaqala ukwenza izixhobo ze-carbide kwaye yafunyanwa ngokubanzi.


Kwiminyaka yoo-1950, iSweden kunye ne-United States ngokulandelelanayo zadibanisa izixhobo zokusika idayimani ezenziweyo, ngaloo ndlela zingena kwixesha elimelwe yimathiriyeli enzima kakhulu. Ngeminyaka yoo-1970, idayimani ye-polycrystalline (PCD) yadityaniswa kusetyenziswa itekhnoloji yoxinzelelo oluphezulu, eyandisa umda wokusetyenziswa kwezixhobo zedayimani kuphapho, i-aerospace, iimoto, i-electronics, ilitye, kunye namanye amacandelo.


Iimpawu zokusebenza kwezixhobo zePCD

Izixhobo zokusika idayimane zineempawu zobunzima obuphezulu, amandla aphezulu oxinzelelo, ukuhanjiswa kakuhle kwe-thermal, kunye nokumelana nokunxiba, okunokufezekisa ukuchaneka okuphezulu kwe-machining kunye nokusebenza kakuhle kwi-high-speed cut.


Ukusetyenziswa kwezixhobo zePCD

Ukusukela ukuba idayimani yokuqala ye-polycrystalline yenziwa eSweden ngo-1953, uphando malunga nokusebenza kokusika kwezixhobo ze-PCD lufumene iziphumo ezininzi, kwaye umda wesicelo kunye nokusetyenziswa kwezixhobo ze-PCD ziye zanda ngokukhawuleza.


Okwangoku, abavelisi abadumileyo bamazwe ngamazwe beedayimani ze-polycrystalline ikakhulu baquka i-De Beers Company yase-United Kingdom, i-GE Inkampani yase-United States, i-Sumitomo Electric Co., Ltd. yaseJapan, njl. Kubikwa ukuba kwikota yokuqala ye-1995, Imveliso yesixhobo sePCD yaseJapan iyodwa yafikelela kumaqhekeza angama-107,000. Umda wesicelo sezixhobo ze-PCD uye wanda ukusuka kwinkqubo yokuqala yokujika ukuya kwiinkqubo zokomba kunye nokusila. Uphando malunga nezixhobo ezinzima kakhulu ezenziwa ngumbutho waseJapan lubonise ukuba eyona ngqwalasela iphambili yokuba abantu bakhethe izixhobo zePCD zisekwe kwiingenelo zokuchaneka komphezulu, ukuchaneka komgangatho, kunye nobomi besixhobo emva kokucubungula ngezixhobo zePCD. Itekhnoloji yokudityaniswa kwamaphepha adityanisiweyo edayimani nawo aphuhliswe kakhulu.


ZZBETTER PCD izixhobo

Izixhobo ze-PCD ze-ZZBETTER zibandakanya amabakala ahlukeneyo kunye noqwalaselo lwe-dimensional. Uluhlu lwemveliso lubandakanya amabakala anemilinganiselo yeenkozo eziqhelekileyo ukusuka kwi-5 ukuya kwi-25 microns kunye ne-62mm ububanzi obusebenzisekayo. Iimveliso ziyafumaneka njengeediski ezipheleleyo okanye iingcebiso ezisikiweyo ngokwahluka ngokubanzi kunye nobukhulu bomaleko we-PCD.


Iinzuzo zokusebenzisa i-ZZBETTER PCD zibonelela ngokusebenza okuthembekileyo kunye nokuhambelanayo ngexabiso elikhuphisanayo. Iphucula ukulula kokwenziwa, inika amandla amazinga aphezulu okutya, kwaye ibonelela ngokuphucuka kokumelana nokunxiba kwezixhobo ezahlukeneyo zokusebenza. Iquka amabakala amaninzi kunye ne-tungsten carbide additive kwi-PCD layer, eyenza abenzi bezixhobo bakhuphe oomatshini bombane (EDM) kunye / okanye ukukhutshwa kombane (EDG) ngokukhawuleza. Uluhlu lwayo olubanzi lwamabakala luvumela ukuguquguquka ekukhetheni izinto ezifanelekileyo kuso nasiphi na isicelo somatshini


Kuba Woodworking

Ukwandisa izinga lokutya kunye nokuphucula ubomi besixhobo kwizicelo zemithi ezifana ne-medium-density fiberboard (MDF), i-melamine, i-laminates, kunye ne-particleboard.


Kushishino olunzima

Yandisa ukumelana nokunxiba kunye nokunciphisa ixesha lokuphumla kwilitye lomatshini, ikhonkrithi, ibhodi yesamente, kunye nezinye izinto zokusebenza ezirhabaxa.


Ezinye ii-aplikeshini

Ukunciphisa iindleko zesixhobo kunye nokwandisa ukuhambelana koluhlu olubanzi lwezinto ezinzima-kumatshini, ezifana ne-carbon composite, i-acrylics, iglasi, kunye nezinye izinto ezininzi ezingenayo i-nonferrous kunye ne-nonmetallic.


Iimpawu xa kuthelekiswa nezixhobo ze-tungsten carbide:

I-1, Ukuqina kwe-PCD yi-80 ukuya kwi-120 amaxesha e-tungsten carbide.

2. I-thermal conductivity ye-PCD yi-1.5 ukuya kwi-9 amaxesha e-tungsten carbide.

3. Ubomi bezixhobo zePCD bunokudlula ubomi besixhobo sokusika i-carbide ngamaxesha angama-50 ukuya kwangama-100.


Iimpawu xa kuthelekiswa nezixhobo zedayimane zendalo:

I-1, i-PCD ixhathisa ngaphezu kweedayimani zendalo ngenxa yesakhiwo sokuqhelaniswa okungahleliwe kweengqungquthela zedayimane kwaye ixhaswa yi-carbide substrate.

I-2, i-PCD isoloko inxiba ngenxa yenkqubo epheleleyo yokuvelisa yokulawula umgangatho, idayimani yendalo yikristale enye kwindalo kwaye ineenkozo ezithambileyo nezilukhuni xa zenziwe isixhobo. Ayizukusetyenziswa kakuhle ngeenkozo ezithambileyo.

I-3, i-PCD inexabiso eliphantsi kwaye ineemilo ezahlukeneyo kunye nobukhulu onokukhetha kuzo kwisixhobo, idayimani yendalo ngumda kula manqaku.



Izixhobo zokusika ze-PCD zisetyenziswa ngokubanzi kwishishini ngenxa yomgangatho wabo wokuqhuba kakuhle kunye noqoqosho lokuqhuba. Ibonisa iingenelo ukuba ezinye izixhobo azikwazi ukuhambelana nezinto ezingezizo ezentsimbi, iintsimbi ezingezizo ezoni kunye nezixhobo zazo zealloy, kunye nezinye izinto zokusika. Ukujula kophando lwethiyori kwizixhobo zokusika zePCD kukhuthaza indawo yezixhobo zePCD kwintsimi yezixhobo ezinzima kakhulu. I-PCD iya kubaluleka kakhulu, kwaye umda wesicelo sayo nawo uya kwandiswa ngakumbi.
