Izingcezu zokubhola ze-PCD zekhwalithi ephezulu zokunemba kwezinsimbi ezikhethekile
Incazelo Yomkhiqizo
Indlela yokulungiselela ye-PCD drill bits ngokuvamile iwukucubungula i-groove endaweni yokubhoboza, sebenzisa ukusika ucingo ukusika ifilimu ye-PCD efakwe ku-substrate ye-carbide enosimende ukuze ibumbe, bese uyishisela emseleni wethiphu ye-drill bit.Ekuqaleni kwawo-1990, izinsimbi zokubhola ze-PCD ezishiselwe zazisetshenziselwa ukubhoboza izimbobo zokubeka indawo kumapiston enjini yemoto.Ama-piston angama-hypereutectic aluminium alloy castings (okuqukethwe kwe-silicon ngaphezu kuka-12%), futhi izingcezu zokubhoboza ze-PCD kufanele zisetshenziselwe ukucubungula amathuluzi adingekayo.I-Life, i-drill ngokuvamile ingacubungula amapheya angu-3,500 emigodi uma isiloliwe (empeleni, ingase icubungule amapheya angu-10,000 ezimbobo).Kodwa-ke, isikhathi sokucubungula se-PCD drill bit esishiselwe side, futhi izindleko zokucubungula ucezu ngalunye ziphezulu.Ngaphezu kwalokho, umkhawulo wokusika we-drill uvame ukubhekana nokwehluleka kwe-welding ngaphansi kwesenzo sokushisa okuphezulu, okuholela ekulimaleni kwe-drill yonke.Ukusetshenziswa kwamabhithi okubhola e-PCD ahlanganisiwe kungaxazulula kangcono izinkinga ezingenhla.
Isakhiwo Izinhlamvu
Izindawo zokufaka isicelo: 3C, izimoto, i-aerospace, njll.;
Izinto ezisetshenziswayo: i-aluminium, i-magnesium, i-titanium, i-silicon nezinye izinsimbi ezingenayo insimbi;fibre materials, insulating materials, plastics, composite materials, njll .;
Isigaba sebhithi ye-PCD drill: I-PCD twist drill, i-PCD integral sintered drill, i-PCD countersink drill, i-PCD reaming drill compound cutter, i-PCD step drill, i-PCD i-groove drill eqondile, i-PCD imbobo ejulile ye-PCD, njll.

Izinzuzo
Inobunzima obuphakeme kakhulu kanye nokumelana nokugqokwa okukhulu;
Ukusebenza okuzinzile kanye nempilo yamathuluzi emide;
Ukusebenza okuzinzile kokusika, ukusebenza kahle kokucubungula okuphezulu;
Kungatholakala isiphetho esiphezulu.
