Tapered HSS maroojin Drill Bit oo leh oksaydh madow dhammayn
Astaamaha
1.High Speed Steel (HSS) dhismaha
2.Naqshadaynta Tapered:
3.Daawaynta dusha sare ee oksaydhka
4.Dhibaatooyinkan laydhka ah waxaa loogu talagalay inay la jaanqaadaan qalabyada kala duwan ee qodista, iyagoo siinaya fududaynta isticmaalka iyo kala duwanaanta qalabka mashiinka kala duwan.
Isku soo wada duuboo, qalabka wax lagu duubo ee HSS oo leh dhamaystirka oksaydhka madow wuxuu bixiyaa adkeysiga, saxnaanta, iska caabinta daxalka, iyo kala duwanaanshaha, taasoo ka dhigaysa qalab qiimo leh oo loogu talagalay baahiyo qodid oo kala duwan.

Faa'iidooyinka
1.Heat caabbinta: Qalabka birta ah ee xawaaraha sare leh waxay u adkeysan kartaa heerkulka sare ee la soo saaro inta lagu jiro qodista, yaraynta khatarta kuleylka iyo ilaalinta waxtarka goynta.
2.Precision Drilling: Naqshadaynta dhejisku waxay u oggolaanaysaa isku-habboonaanta iyo saxnaanta, taas oo ka dhigaysa mid ku habboon abuurista godadka saxda ah ee qalabyada kala duwan.
3.Naqshadaynta biibiile ee spiral waxay kor u qaadaa daadgureynta fiilooyinka wax ku oolka ah, yaraynta khatarta xiritaanka iyo hagaajinta waxqabadka qodista.
4.The tapered HSS maroojin biibiile daahan madow oxide ku haboon qodista noocyo kala duwan oo qalab ah oo ay ku jiraan biraha, alwaax, balaastiig iyo composites, bixinta kala duwan ee codsiyada kala duwan.
5.Daawaynta dusha sare ee oksaydhka madow waxay ka caawisaa in la yareeyo khilaafka inta lagu jiro qodista, taasoo keentay hawlgalo qodid oo fudud iyo kuleyl badan oo kor u kaca.
6.Isku-darka dhismaha birta-xawaaraha sare leh iyo daaweynta dusha sare ee oksaydhka madow waxay ka caawisaa in la gaaro waxqabad waqti dheer ah oo la yareeyo inta jeer ee beddelka qalabka.
