Niki PDC bit Cutter？

Diamond ni ibintu bikomeye bizwi. Uku gukomera kuyiha imitungo isumba iyindi yo gukata ibindi bikoresho. PDC (Compact ya polycrystalline compact) ni ingenzi cyane mu gucukura kuko ikusanya diyama ntoya, ihendutse, yakozwe n'abantu muri diyama nini cyane, ikura hagati ya kristu yerekanwe ku buryo butemewe ishobora gukorwa mu buryo bw'ingirakamaro bwitwa ameza ya diyama. Imbonerahamwe ya diyama nigice cyo gukata gihuza imiterere. Usibye gukomera kwabo, ameza ya diyama ya PDC afite ikintu cyingenzi kiranga ibyuma bitobora: Bihuza neza nibikoresho bya tungsten karbide bishobora gutondekwa (bifatanye) kumubiri. Diyama, yonyine, ntishobora guhuza hamwe, cyangwa ntishobora gufatanwa no gushakisha.

Diyama

Diamond grit isanzwe ikoreshwa mugusobanura ibinyampeke bito (≈0.00004 muri.) Ya diyama ya sintetike ikoreshwa nkibikoresho byingenzi bikata PDC. Ku bijyanye n’imiti n’imiterere, diyama yakozwe n'abantu isa na diyama isanzwe. Gukora diyama grit ikubiyemo uburyo bworoshye bwa chimique: karubone isanzwe ishyuha munsi yumuvuduko mwinshi nubushyuhe. Mubikorwa ariko, gukora diyama ntabwo byoroshye.

Indanganturo ya diyama ya buri muntu ikubiyemo diyama grit yerekanwe muburyo butandukanye. Ibi bituma ibikoresho bikomeye, bikarishye, kandi, kubera ubukana bwa diyama irimo, birwanya kwambara cyane. Mubyukuri, imiterere idasanzwe iboneka muri diyama ya sintetike ihujwe ikora neza mugutemagura kurusha diyama karemano, kubera ko diyama karemano ari kristu ya cubic ivunika byoroshye kumipaka yabyo, itondekanye.

Diamond grit ntabwo ihagaze neza mubushyuhe bwo hejuru kuruta diyama karemano. Kuberako catalizike yumutego wafatiwe muburyo bwa grit ifite umuvuduko mwinshi wo kwaguka kwinshi kurenza diyama, kwaguka gutandukanye gushira diyama-diyama munsi yimyenda kandi, niba imizigo ari myinshi bihagije, itera kunanirwa. Niba inkwano zananiranye, diyama irazimira vuba, PDC rero itakaza ubukana bwayo nuburakari bikagenda neza. Kugirango wirinde kunanirwa, gukata PDC bigomba gukonjeshwa bihagije mugihe cyo gucukura.

Ameza ya diyama

Gukora ameza ya diyama, grit ya diyama yomekwa hamwe na karubide ya tungsten hamwe na binder metallic kugirango ibe urwego rukungahaye kuri diyama. Bimeze nka wafer muburyo, kandi bigomba gukorwa mubyimbye nkibishoboka kuko ingano ya diyama yongera ubuzima. Ameza meza ya diyama ni mm2 kugeza kuri 4 mm, kandi iterambere ryikoranabuhanga rizongera umubyimba wameza ya diyama. Tungsten karbide substrate isanzwe ≈0.5 muri. Hejuru kandi ifite imiterere-nini-nini-nini-imwe ya ameza ya diyama. Ibice byombi, ameza ya diyama, hamwe na substrate, bigize icyuma

Kubaka amashanyarazi ya PDC.

Gukora PDC muburyo bwingirakamaro kubakata bikubiyemo gushyira diyama grit, hamwe na substrate yayo, mukibindi cyumuvuduko hanyuma ugacumura mubushyuhe bwinshi nigitutu.

Gukata PDC ntibishobora kwemererwa kurenza ubushyuhe bwa 1,382 ° F [750 ° C]. Ubushyuhe bukabije butera kwambara vuba kuko itandukaniro ryubushyuhe butandukanye hagati ya binder na diyama ikunda kumena diyama ya grit kristal ikura kumeza ya diyama. Imbaraga zingana hagati yameza ya diyama na tungsten karbide substrate nayo ibangamiwe no kwaguka kwinshi gutandukanye.

Niba ushimishijwe nibicuruzwa bya tungsten ukaba ushaka amakuru arambuye, urashobora kutwandikira ukoresheje terefone cyangwa amabaruwa ibumoso, cyangwa UKOHEREZA MAIL US hepfo yurupapuro.
