Codsiga
Roller cone bit waa qalabka ugu badan ee loo isticmaalo qodista batroolka iyo qodista juqraafiga.Xoogaa Tricone waxay leedahay shaqada saamaynta, burburinta iyo xiirida dhagaxa samaynta, si ay ula qabsato qaab-dhismeed jilicsan, dhexdhexaad ah iyo adag.Qaniinyada kolayga waxa loo qaybin karaa wax-shiidka (ilkaha birta) kolayga birta iyo qaniinyada kolayga ee TCI iyadoo loo eegayo nooca ilkahu.
Astaamaha
Marka loo eego walxaha goynta, waxa loo qaybin karaa ilig bir ah (Ilig-shiid kiimikaad) iyo tungsten carbide insert (TCI) qaniinyada koodhka iliga.
TCI Tricone waxay qodaysaa qodista samaynta dhagxaanta dhexdhexaadka ah iyo kuwa adag.
Samaynta dhexdhexaadka ah ee TCI tricone bits waxay ka kooban tahay dhejisyo tungsten carbide ah oo gardarro leh oo la gelinayo safafka cidhibta iyo safafka gudaha.
Naqshadani waxay bixisaa heerka qodista degdega ah iyo ku darista adkaysiga qaab dhismeedka goynta ee qaababka adag ee dhexdhexaadka ah.Ring-ga caagga ah ee HSN waxa uu bixiyaa xidhid ku filan oo adkeysiga.
Samaynta adag ee TCI tricone bits waxaa loo isticmaali karaa in lagu qodo samaynta adag iyo abrasive.Xiro caabbinta tungsten kaarbiide waxa loo isticmaalaa safafka dibadda si looga hortago luminta xoogaa cabbirka.Tirooyinka ugu badan ee gashanaya qaab hemispherical ayaa loo isticmaalaa dhammaan safafka si loo bixiyo cimri dherer iyo cimri dheer.
