Yikuphi okungcono, okuqondile noma okuphambene?

Igama elithi "i-drill-shaped drill bit" livela eqinisweni lokuthi i-alloy blade eqinile emise okwesiphambano ishiselwe phezulu kwe-drill bit. Eyaziwa nangokuthi ibhithi yenkinobho emise okwesiphambano, umzimba we-drill omise okwesiphambano wenziwe ngensimbi engu-50Cr futhi wakhiwe nge-hot extrusion, ene-blade ephezulu eyenziwe nge-alloy eqinile futhi engagugi. Uma kuziwa ekuthungeni, ezinye zinezintambo, kanti ezinye azinazo; lezo ezingenazo izintambo zixhunywe ngokuqondile ku-drill rod. Osayizi abajwayelekile bezinsimbi zokubhola ezimise okwesiphambano bahlanganisa φ28, φ32, φ34, φ36, φ38, kanye no-φ40, usayizi ongu-40 iwona osetshenziswa kakhulu. Izingcezu zokubhoboza ezimise okwesiphambano zisetshenziswa ikakhulukazi ezimayini, ekumbiweni komhubhe, nakumaphrojekthi wokwakha, okuvumela ukumba emadwaleni noma kumalahle ngaphandle kokunciphisa ukusebenza kahle kokumba ngisho nalapho kukhiqiza ama-chips amakhulu. Ukusesha i-Yimei Machinery Manufacturing Co., Ltd. kuzohlinzeka ngolwazi olwengeziwe.

Izici zezingcezu zokubhola ezimise okwesiphambano zifaka izinqubo zokukhiqiza ezilula, ukusetshenziswa okulula, amanani aphansi, kanye nokuvumelana nezimo zamadwala. Ngezinqubo zokukhiqiza ezilula, ukugaywa kabusha okulula, nokusebenza okuthembekile, izinsimbi zokubhola ezimise okwesiphambano zivumelana nezimo ezihlukahlukene zamadwala. Zivame ukusetshenziswa ngokushisa kwangaphakathi okukhanyayo, ugesi, umoya womoya, kanye ne-hydraulic rock drill ukubhoboza izimbobo ezinobubanzi obungaphansi kuka-D50mm ezinhlotsheni ezahlukene zamadwala. Ngenxa yezindleko eziphansi nezinye izici, izinsimbi zokubhola ezimise okwesiphambano zisasetshenziswa kabanzi embonini yezimayini yaseShayina ukumba izimbobo zamatshe amancane naphakathi nendawo.
