1. Convex type: Qhov no me ntsis tuaj nyob rau hauv ob daim ntawv, ib tug thawj coj thiab ob tug thawj coj.Cov yav tas yog tsuas yog siv rau loj-inch DDP khoom.
Convex DDRs tuaj yeem khaws tus nqi siab drilling thaum drilling tawv thiab tawv abrasive pob zeb, tab sis qhov flatness ntawm drilling tsis zoo, yog li nws tsis haum rau drilling engineering uas yuav tsum tau siab flatness ntawm blasting qhov.
2, lub ntsej muag tiaj tus: cov duab ntawm lub laum no kuj muaj zog thiab ruaj khov, haum rau drilling tawv thiab tawv pob zeb, tab sis kuj haum rau drilling qhov flatness tsis yog siab ntawm nruab nrab nyuaj pob zeb thiab pob zeb mos.
3. Concave hom: lub ntsej muag kawg ntawm lub taub hau me ntsis nrog cov duab no muaj lub conical kev nyuaj siab, uas yog tsim los ntawm me ntsis nyob rau hauv tus txheej txheem ntawm drilling kom lub centering kev ua tau zoo ntawm me ntsis, thiab lub qhov drilling muaj zoo ncaj.Cov me me no muaj cov hmoov zoo tso tawm thiab ua kom nrawm nrawm, thiab yog qhov feem ntau siv DWB me ntsis ntawm kev ua lag luam.
4, kawg lub ntsej muag sib sib zog nqus concave chaw hom: qhov zoo li ntawm qhov me me yog hloov zuj zus los ntawm tib hom pob hniav me ntsis, qhov nruab nrab ntawm qhov kawg ntawm lub ntsej muag ntawm qhov me me muaj qhov sib sib zog nqus concave qhov chaw.
Nws yog siv rau nucleation nyob rau hauv cov txheej txheem ntawm drilling pob zeb.Thaum drilling qhov tob, nws tuaj yeem ua kom lub tiaj tiaj ntawm rab phom qhov.Nws tsuas yog tsim rau drilling pob zeb mos thiab nruab nrab nyuaj pob zeb.
