I-PDC yokusika ubuso engahleliwe

Kuwo wonke umlando wokumba endaweni kawoyela, izisebenzi ziye zazama ukuthuthukisa ukusebenza kahle komshini wokubhoboza. Imibono eyahlukene yokusika, imiklamo, kanye nezinto zokwakha zisetshenziswe ukuze kukhuliswe Izinga Lokungena (ROP), ukumelana nokugqoka, kanye nempilo yonke kancane. Ubuchwepheshe bendabuko bokusika idayimane le-polycrystalline (i-PDC) buye benza izinzuzo ezinkulu kule minyaka eyishumi edlule ngezithombe ezihambisanayo nezinga lokungena (i-ROP) ekuthuthukisweni kokusebenza kokumba. Inselele esele iwukuphatha ukwakheka okuyinkimbinkimbi ngamayunithi ezinhlamvu anekhono kuyilapho kugcinwa ukusebenza kahle kokumba kanye namandla aphezulu e-ROP.

Ukusebenza kahle okuphansi kokuphulwa kwetshe kwamabhithi edayimane e-polycrystalline compact (PDC) avamile ekwakhekeni okunamathelayo okuqinile kwazisa ukuthuthukiswa kwezinto zokusika ze-PDC ukusuka kupulani kuya esakhiweni esingahleliwe. Ngokushintsha i-planar PDC cutter face geometry enezici ezintsha ezingajulile, ukuthuthukiswa okubonisiwe ekusebenzeni kahle kokumba kubonwe kulezi zinhlelo zokusebenza kanye nokwanda kwezithombe ezitholiwe. Ngokuhlaziya imithelela ye-engeli ye-back-rake, ukujula kokusika, i-engeli ejikelezayo, kanye nezakhiwo zamadwala ekusebenzeni kahle kokuphuka kwamadwala, sithola ukuthi umsiki ongahleliwe uhlephula idwala ikakhulukazi ngokuchoboza nokugunda futhi usebenza kahle kakhulu kunomsiki we-PDC ojwayelekile. Lapho ibhithi le-PDC elinama-convex ridge e-PDC abasiki bebhola libhojwa ongqimbeni lwetshe, igravel ayisathinti ngokuqondile indiza eyinhlanganisela yedayimane kodwa yenza ukuthintana okuqondile ne-convex ridge. Amagquma abasiki be-PDC aqala athintane nokwakheka bese akhama igravel, okuholela ekugxilweni kwengcindezi kungqimba olungaphezulu lwetshe, okulwenza luthambekele kakhulu ekuqhekekeni nasekuqhekekeni kwasekuqaleni. Uhlelo lokusebenza lwensimu lubonisa ukuthi i-PDC yokusika i-non-planar kulula ukungena ekubunjweni kune-cutter evamile futhi izinzile ne-torque encane edingekayo.

Kwa-ZZBETTER, singanikela ngabasiki be-planar kanye nabasiki be-PDC abangahleliwe, kuyilapho abasiki be-non-planar abanokumelana nomthelela ongcono kakhulu, ukumelana nokugqoka okuphezulu nokuzinza. Njengoba amakhasimende ethu eshilo: ama-PDC planar cutters ahlakaniphile, kulula kakhulu ukuwasebenzisa.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma nge-imeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
