Ungayikhetha kanjani i-drill?

Namuhla, ngizokwabelana ngendlela yokukhetha i-drill bit ngezimo ezintathu eziyisisekelo zei-drill bit, okuyilezi: izinto zokwakha, ukumboza kanye nezici zejiyometri.

Indlela yokukhetha izinto zomshini wokubhoboza

Izinto zokwakha zingahlukaniswa cishe zibe izinhlobo ezintathu: insimbi enesivinini esikhulu, insimbi enesivinini esikhulu equkethe i-cobalt kanye ne-carbide eqinile.

Insimbi Esheshayo (i-HSS):

Insimbi yesivinini esiphezulu okwamanje iyindlela yokusika esetshenziswa kakhulu futhi eshibhile kakhulu. Ingxenye yokubhoboza yensimbi yesivinini esiphezulu ingasetshenziswa hhayi kuphela kuma-drill kagesi asetshenziswayo, kodwa futhi nasezindaweni ezinokuqina okungcono njengemishini yokubhoboza. Esinye isizathu sokuphila isikhathi eside kwensimbi yesivinini esiphezulu kungaba ukuthi ithuluzi elenziwe ngensimbi yesivinini esiphezulu lingagaywa ngokuphindaphindiwe. Ngenxa yentengo yalo ephansi, alisetshenziswa nje kuphela ekugayweni libe yizingcezu zokubhoboza, kodwa futhi lisetshenziswa kabanzi ekuphenduleni amathuluzi.

Insimbi Esheshayo Ye-Cobalt (HSSCO):

Insimbi yesivinini esiphezulu equkethe i-cobalt inobulukhuni obungcono kanye nobulukhuni obubomvu kunensimbi yesivinini esikhulu, kanti ukwanda kobulukhuni kuthuthukisa nokumelana kwayo nokuguguleka, kodwa ngesikhathi esifanayo kudela ingxenye yokuqina kwayo. Okufanayo nensimbi yesivinini esikhulu: zingasetshenziswa ukuthuthukisa inani lezikhathi ngokugaya.

 

I-Carbide (i-CARBIDE):

I-carbide esimende iyinto ehlanganisiwe esekelwe ensimbini. Phakathi kwazo, i-carbide ye-tungsten isetshenziswa njenge-matrix, kanti ezinye izinto zezinye izinto zisetshenziswa njenge-binder ezoshiswa uchungechunge lwezinqubo eziyinkimbinkimbi njengokucindezela okushisayo kwe-isostatic. Uma kuqhathaniswa nensimbi yesivinini esikhulu maqondana nobulukhuni, ubulukhuni obubomvu, ukumelana nokuguguleka, njll., kukhona ukuthuthuka okukhulu, kodwa izindleko zamathuluzi e-carbide esimende nazo zibiza kakhulu kunensimbi yesivinini esikhulu. I-Carbide inezinzuzo eziningi kunezinto zamathuluzi zangaphambilini maqondana nokuphila kwamathuluzi kanye nesivinini sokucubungula. Ekugayweni okuphindaphindiwe kwamathuluzi, kudingeka amathuluzi okugaya ochwepheshe.

Indlela yokukhetha i-drill coating

Izembozo zingahlukaniswa cishe zibe izinhlobo ezinhlanu ezilandelayo ngokuya ngobubanzi bokusetshenziswa.

Okungagqokwanga:

Imimese engagqokwanga iyona eshibhile futhi ivame ukusetshenziselwa ukukhanda izinto ezithambile njenge-aluminium alloys kanye nensimbi ethambile.

Ukugqoka kwe-oxide emnyama:

Izembozo ezifakwe i-oxidized zinganikeza ukuthambisa okungcono kunamathuluzi angagqokwanga, futhi zingcono futhi maqondana ne-oxidization kanye nokumelana nokushisa, futhi zingandisa impilo yesevisi ngaphezu kuka-50%.

Ukugqoka kwe-titanium nitride:

I-titanium nitride iyinto evame kakhulu yokumboza futhi ayifaneleki ukucubungula izinto ezinobunzima obuphezulu kanye nokushisa okuphezulu kokucubungula.

Ukugqoka kwe-titanium carbonitride:

I-titanium carbonitride yakhiwe nge-titanium nitride futhi inokushisa okuphezulu kanye nokumelana nokuguguleka, ngokuvamile okunsomi noma okuluhlaza okwesibhakabhaka. Isetshenziselwa ukukhiqiza izinto zokusebenza zensimbi emshinini wokusebenzela waseHaas.

Ukugqoka kwe-Aluminium Nitride Titanium:

I-aluminium titanium nitride imelana kakhulu namazinga okushisa aphezulu kunazo zonke izembozo ezingenhla, ngakho-ke ingasetshenziswa ezindaweni zokusika eziphakeme. Isibonelo, ukucubungula ama-superalloys. Ifanele futhi ukucubungula insimbi nensimbi engagqwali, kodwa ngenxa yezinto eziqukethe i-aluminium, kuzovela ukusabela kwamakhemikhali lapho kucubungula i-aluminium, ngakho-ke gwema ukucubungula izinto eziqukethe i-aluminium.

I-geometry ye-drill bit

Izici zejometri zingahlukaniswa zibe izingxenye ezintathu ezilandelayo:

Ubude

Isilinganiso sobude nobubanzi sibizwa ngokuthi ububanzi obuphindwe kabili, futhi uma ububanzi obuphindwe kabili buncane, kuba ngcono ukuqina. Ukukhetha i-drill enobude bomphetho ukuze kususwe ama-chip kanye nobude obufushane bokulenga kungathuthukisa ukuqina ngesikhathi somshini, ngaleyo ndlela kwandise impilo yenkonzo yethuluzi. Ubude be-blade obunganele cishe buzolimaza i-drill.

I-engeli yesihloko sokubhoboza

I-engeli yokubhoboza engu-118° cishe iyona evame kakhulu ekushicileleni futhi ivame ukusetshenziselwa izinsimbi ezithambile njengensimbi ethambile ne-aluminium. Umklamo waleli engeli ngokuvamile awuzigxilisi, okusho ukuthi akunakugwenywa ukubhoboza imbobo ephakathi kuqala. I-engeli yokubhoboza engu-135° ngokuvamile inomsebenzi wokuzigxilisa. Njengoba kungekho sidingo sokubhoboza imbobo ephakathi, lokhu kuzokwenza kungadingeki ukubhoboza imbobo ephakathi ngokwehlukana, ngaleyo ndlela konge isikhathi esiningi.

I-engeli ye-Helix

I-engeli ye-helix engu-30° iyisinqumo esihle sezinto eziningi. Kodwa ezindaweni ezidinga ukususwa okungcono kwe-chip kanye nomkhawulo wokusika oqinile, kungakhethwa i-drill ene-engeli encane ye-helix. Ezintweni ezilukhuni ukwenza umshini njengensimbi engagqwali, umklamo one-engeli enkulu ye-helix ungakhethwa ukuze udlulise i-torque.
