Yakaisirwa Core Bit
Dhizaini yeiyo yepamusoro ROP mukuboora kwakadzika uye kwakaomarara mafomati, PDC yekuboora zvishoma inogara ichaboora kubva pasi kusvika pasi zvakananga nekumhanya kushoma kana kunyangwe kamwe chete, ichichengetedza yakawanda yenguva yekuboora uye mutengo.
Zvakasiyana netricone bit, PDC chibooreso chinomhanya nechepasi WOB asi Yakakwirira RPM, saka inowanzo shanda nemadhorobha mota kutora kutenderera kumhanya.
Iko kushanda kwePDC chibooreso kunoenderana zvakanyanya nePDC cutters, isu tinopa yakasarudzika mhinduro kune yakatarwa chinodikanwa pane akasiyana mafomu.
Kuchera mune zvakaomesesa mafomati Iyo inokodzera kukora mune akaomesesa akaomarara maitiro, senge sandstone.
Zvimiro
◆ Yakakombama korona
Korona yakakombama ine mushe mushe
◆ Radiant yemvura dhizaini
Iyo bit ine inopenya yemvura dhizaini iyo inokodzera kumhanya kwazvo.

◆ Iyo yekuzvirodza-yakazvimiririra yekuisa
Iyo yekuzvirodza-yakatemerwa yekuisa inochengetedza iyo yekucheka yakapinza panguva yekuchera.
◆ Iyo yakasarudzika matrix fomula
Iyo yakasarudzika matrix fomula inoita kuti matrix ifanane nekusakara uye kuumbwa, inogonesa iyo yekucheka
Nhanganyaya:
Iyo inokodzera coring mune yakaoma zvakanyanya hasha mafomu, senge sandstone.
Zvimiro
1.Curved korona: Korona yakakombama ine mushe mushe
2.Iyo yekuzvirodza-yakarongedzwa yakaiswa muwedzero: Iyo yekuzvirodza-yakatemerwa yekuisa inochengetedza iyo yekucheka yakapinza panguva yekuchera.
3.Iyo yakasarudzika matrix fomula: Iyo yakasarudzika matrix fomula inoita kuti matrix ifanane nekusakara uye kuumbwa, inogadziridza iyo yekucheka kumucheto uye kupfeka kuramba kwedhaimani izvo zvinoita kuti iyo diki iwane iri nani ROP.
4.Radiant yemvura dhizaini: Iyo bit ine inopenya yemvura dhizaini iyo inokodzera kumhanya kwazvo.
