Zingaki izimbozo zomphezulu ze-HSS drill bit? futhi yikuphi okungcono?

Ama-drill bits ensimbi enesivinini esikhulu (i-HSS) avame ukuba ne-surface coating ehlukene eyenzelwe ukuthuthukisa ukusebenza kwawo kanye nokuqina kwawo. I-surface coating evame kakhulu yama-drill bits ensimbi enesivinini esikhulu ifaka:

1. Isimbozo se-Black Oxide: Lokhu kugqoka kunikeza izinga elithile lokumelana nokugqwala futhi kusiza ekunciphiseni ukungqubuzana ngesikhathi sokubhoboza. Kuphinde kusize ukugcina amafutha ebusweni bokubhoboza. Izingcezu zokubhoboza ezimbozwe nge-oxide emnyama zifanelekela ukubhoboza ngenhloso evamile ezintweni ezifana nokhuni, ipulasitiki kanye nensimbi.

2. Isimbozo se-Titanium Nitride (TiN): Ukwembozwa kwe-TiN kwandisa ukumelana nokuguguleka futhi kusiza ekunciphiseni ukungqubuzana, ngaleyo ndlela kwandise impilo yamathuluzi futhi kuthuthukise ukusebenza ekusetshenzisweni kokubhoboza okushisa okuphezulu. Ama-drill bits ambozwe yi-TiN afanelekela ukubhoboza izinto eziqinile njengensimbi engagqwali, insimbi ephonswe, kanye ne-titanium.

3. Ukugqoka kwe-Titanium carbonitride (TiCN): Uma kuqhathaniswa nokugqoka kwe-TiN, ukugqoka kwe-TiCN kunokumelana nokuguguleka okuphezulu kanye nokumelana nokushisa. Kufanelekile ukubhoboza izinto ezisusa ukungcola kanye nezinto ezishisa kakhulu ukuthuthukisa impilo yamathuluzi kanye nokusebenza kahle ekusetshenzisweni kokubhoboza okudingakalayo.

4. Isembozo se-titanium aluminium nitride (TiAlN): Isembozo se-TiAlN sinezinga eliphakeme kakhulu lokumelana nokuguguleka kanye nokumelana nokushisa phakathi kwesembozo esingenhla. Sifanele ukubhoboza izinsimbi eziqinile, ama-alloy okushisa okuphezulu kanye nezinye izinto eziyinselele zokwandisa isikhathi samathuluzi nokuthuthukisa ukusebenza ezimweni ezinzima zokubhoboza.

Ukuthi yikuphi ukugqoka okungcono kuncike ekusetshenzisweni okuthile kokubhoboza kanye nezinto ezibhobozwayo. Ukugqoka ngakunye kunikeza izinzuzo ezihlukile futhi kwenzelwe izinhlobo ezahlukene zezinto kanye nezimo zokubhoboza. Ukuze kubhobozwe izinto ezivamile, i-drill bit eboshwe nge-oxide emnyama ingaba yanele. Kodwa-ke, ukuze kusetshenziswe izinto ezidinga kakhulu ezihlanganisa izinto eziqinile noma ezishisa kakhulu,Ama-drill bits ambozwe nge-TiN, TiCN noma i-TiAlN angase afaneleke kakhulu ngenxa yokuguguleka kwawo okuthuthukisiwe kanye nokumelana nokushisa.
