Umahluko phakathi kwePDC kunye nePCD

I-PDC kunye ne-PCD zombini zizixhobo ezintsha ezinzima kakhulu. Yintoni umahluko phakathi kwabo?

I-PCD (i-Polycrystalline Diamond) yenziwe ngegrit yedayimane. I-diamond grit iye yaxutywa phantsi koxinzelelo oluphezulu, iimeko zobushushu obuphezulu phambi kobukho bentsimbi ye-catalytic. I-PCD inobunzima obugqithisileyo, ukuxhathisa ukunxiba, kunye ne-thermal conductivity kwidayimani, eyenza i-PCD ibe yinto efanelekileyo yokwenza izixhobo zokusika. Izixhobo ze-PCD (ezifana nokufakwa kwe-PCD kunye nee-PCD blades) zinokutshiza zonke izinto ezingenayo i-ferrous ezifana nezo zisetyenziswa kwishishini le-woodworking, i-chipboards, i-HDF, kunye neebhodi ze-laminated. I-PCD isetyenziswa kushishino lweemoto ukuvelisa amacandelo e-aluminiyam kunye nazo zonke izinto ezikhaphukhaphu ezifana ne-carbon fiber eqiniswe iiplastiki (i-CFRP), i-metal matrix composites (MMC), kunye neemfumba zokwakhiwa kweenqwelomoya.

I-PDC (i-Polycrystalline Diamond Compact) ibhekisela kwi-polycrystalline diamond composite okanye i-compact, eyona nto iyisixhobo esiqinileyo phakathi kwazo zonke izixhobo zedayimani. Yenziwe ngokudibanisa ezinye iileyile zedayimane ze-polycrystalline (PCD) kunye noluhlu lwe-carbide substrate ene-cemented kwiqondo lokushisa eliphezulu kunye noxinzelelo oluphezulu. Ubushushu bujikeleze i-1400 ~ 1700 ℃, kwaye uxinzelelo lujikeleze i-6-7 GPA. I-cobalt alloy ikhona kwaye isebenza njenge-catalyst yenkqubo ye-sintering. I-cobalt inceda ukudibanisa i-carbide kunye nedayimane. I-PDC ineenzuzo zokuxhathisa kwedayimani ephezulu kunye nokuqina okuhle kwe-carbide.

Ezona zinto ziluncedo kwiPDC

Ukumelana nokunxiba okuphezulu

Ukuchasana kwempembelelo ephezulu

Ukuzinza okuphezulu kwe-thermal

Ubomi bokusebenza be-PDC cutters bunyuswe ngaphezu kwe-6 ~ 10 amaxesha

Ukunciphisa ukuphindaphindeka kokutshintshwa kweebits zokomba kunye nobunzulu bomsebenzi wabasebenzi.

Ngenxa yokusebenza kwabo okuphezulu, abasiki bePDC basetyenziswa ngokubanzi kule miba ingezantsi:

I-oyile kunye negesi ye-PDC bits njengobuso, igeyiji, kunye nabasiki be-backups

Amasuntswana ePDC okomba i-geothermal

Amasuntswana ePDC okomba amaqula amanzi

Amasuntswana ePDC okomba umkhombandlela

Apha e-zzbetter, Sinikezela ngemilo ebanzi kunye nobukhulu boluhlu lwabasiki bePDC.

Ubume be-zzbetter PDC Cutter

1. Umsiki wePDC oMcaba

2. Iqhosha lePDC elingqukuva

3. Iqhosha leParabolic PDC, iqhosha langaphambili

4. Iqhosha le-PDC le-Conical

5. Abasiki bePDC zesikwere

6. Abasiki be-PDC abangaqhelekanga

Ukuba unomdla kwi PDC cutters kwaye ufuna ulwazi oluthe vetshe kunye neenkcukacha, UNGAQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
