Umgangatho ophezulu wokusebenza ngokuchaneka kwe-PCD amasuntswana e-drill kwiintsimbi ezikhethekileyo
Ingcaciso yeMveliso
Indlela yokulungiselela amasuntswana esiqhelo e-PCD e-drill iqhele ukusetyenzwa kwigroove kwincam ye-drill, sebenzisa ukusika ucingo ukusika ifilimu ye-PCD efakwe kwi-samente ye-carbide substrate ukumila, kwaye emva koko uyidibanise kwincam yencam ye-drill.Ekuqaleni kweminyaka yoo-1990, amasuntswana okubhola ePCD adityanisiweyo ayesetyenziswa ukugrumba imingxuma yokubeka indawo kwiipiston zemoto.Iipiston ziyi-hypereutectic aluminium alloy castings (umxholo we-silicon ngaphezu kwe-12%), kunye ne-PCD drill bits kufuneka isetyenziswe ukucubungula izixhobo ezifunekayo.Ubomi, i-drill idla ngokuqhuba izibini ezingama-3,500 zemingxuma xa sele iloliwe (eneneni, inokuqhuba ipereyi ezili-10,000 zemingxuma).Nangona kunjalo, ixesha lokusetyenzwa kwe-PCD drill bit elidityanisiweyo lide, kwaye iindleko zokusetyenzwa kweqhekeza ngalinye ziphezulu.Ukongezelela, umgca wokusika we-drill uhlala uhlupheka ngenxa yokungaphumeleli kwe-welding phantsi kwesenzo sokushisa okuphezulu, okukhokelela kumonakalo we-drill yonke.Ukusetyenziswa kwe-PCD drill bits ehlanganisiweyo inokusombulula ngcono ezi ngxaki zingentla.
