Ungayikhetha njani i-drill?

Namhlanje, ndiza kwabelana ngendlela yokukhetha i-drill bit ngokusebenzisa iimeko ezintathu ezisisiseko zedrill bit.

Ungayikhetha njani imixholo ye-Drill

Izixhobo zinokwenziwa ukuba zihlulwe zibe ziindidi ezintathu: intsimbi enesidima esiphakamileyo, i-cobalt-eneshole yentsimbi ephezulu kunye ne-carbide eqinileyo.

Isantya esiphezulu sensimbi (HSS):

Insimbi yesantya esiphezulu okwangoku yeyona nto isetyenziswa kakhulu isetyenziswayo kunye nexabiso eliphantsi. Intsimbi encinci yentsimbi inokusetyenziswa kungekuphela nje kwimithombo yombane yesandla, kodwa nakwiimeko ezinozinzo olungcono njengabanyibilikisi. Esinye isizathu sobomi obude besinyithi kakhulu isenokuba sisixhobo esenziwe ngensimbi yesantya esiphezulu. Ngenxa yexabiso layo eliphantsi, ayisetyenziswanga kuphela ukubaleka kwi-bits ye-drill, kodwa isetyenziswa ngokubanzi kwizixhobo.

I-Cobalt Speef Speel Steel (HSCO):

I-Cobabalt-inensimbi yesantya esiphezulu inobunzima obungcono kunye nobunzima obubomvu kunesantya esiphezulu, kunye nokunyuka kobulukhuni kuphucula ukunyangwa kwayo, kodwa kwangaxeshanye inzondelelo yobunzima bayo. Okufanayo nensimbi yesantya esiphezulu: banokusetyenziselwa ukuphucula inani lamaxesha ngokugaya.

 

I-carbide (i-carbide):

I-carbide ye-carbide yindawo yokuhlanganisiwe yentsimbi. Phakathi kwazo, i-tungsten ye-tungsten isetyenziswa njenge-matrix, kwaye ezinye izixhobo zezinto zisetyenziswa njengoko i-binder ingene ngothotho lweenkqubo ezintsonkothileyo ezishushu. Xa kuthelekiswa nentsimbi ehamba ngesantya esiphezulu ngokubhekisele kubulukhuni, ubunzima obubomvu, bunxila, njl njl. I-carbide ineengenelo ngakumbi kunezixhobo zangaphambili Izixhobo zobomi bezixhobo kunye nesantya sokulungisa. Kwisixhobo esiphindaphindiweyo sezixhobo, izixhobo zokugcuma eziqeqeshiweyo ziyafuneka.

Ungayikhetha njani i-Drill Deance

Ingubo yangaphantsi inokuba phantse kwezi ntlobo zintlanu zintlanu ngokobungakanani bokusetyenziswa.

I-tooty:

Iimpeni ezingabhalwanga zezo tyhefu kwaye zihlala zisetyenziselwa izixhobo zokuthambisa ezinjengeealloys kunye nentsimbi ethambileyo.

I-Oneam emnyama

I-Oxidared I-Coasthings inokubonelela ngotywala obungcono kunezixhobo ezingaziwayo, kwaye ikwangcono nangokuchasene nobushushu, kwaye inokunyusa ubomi benkonzo ngaphezulu kwe-50%.

I-titanium witride

I-titanium ndride yeyona nto ixhaphakileyo kwaye ayilunganga kwizinto zokwenza izinto ezinzima kunye nobushushu obuphezulu.

I-titanium ye-carbonitrive i-comaing:

I-Titanium Carbonitride iphuhliswa ukusuka kwi-Titanium ndride kwaye inamaqondo aphezulu obushushu obuphezulu kwaye unxibe ukunganyangeki, ngokufuthi okanye iblowu. Isetyenziselwa ukuya kumatshini wokusebenza kwi-Iron Drimies kwindibano ye-Haas.

I-Aluminium Nitride Diatium Coom:

I-Aluminium Titanium Nitride inyangeka ngakumbi kubushushu obuphezulu ngakumbi kunazo zonke ezi ntlawulo zingasentla, ukuze zisetyenziswe kwiindawo ezinqamlezileyo. Umzekelo, ukuqhuba i-sueralloys. Ikwakulungele ukuqhubekiswa kwentsimbi yentsimbi kunye nentsimbi engenasibala, kodwa ngenxa yezinto eziqulatha i-aluminium, ukuphendula kweekhemikhali kuyakwenzeka xa kusenziwa izixhobo ze-aluminium ezinee-aluminium-ezinemigangatho ye-aluminium.

I-Drill Git Geometry

Iimpawu zejometri zinokwahlulwahlulwahlulwahlulwa kwezi zinto zi-3 zilandelayo:

Ubude

Umyinge wobude obuya kububanzi bubizwa ngokuba bubukhulu obuphindwe kabini, kwaye buncinci ubukhulu obuphindiweyo, okungcono ubungqola. Ukukhetha i-drill ngobude bomphetho nje ngokususwa kwe-chip kunye nobude obugqithisileyo obungaphezulu kunokuphucula ubungqola ngexesha lokwenzakala, ngaloo ndlela kunyusa ubomi benkonzo yesixhobo. Ubude obungonwabanga bungawonakalisayo buya konakalisa i-drill.

Drill i-tit engle

I-tit ye-till ye-118 ° yeyona ixhaphakileyo yomatshini kwaye ihlala isetyenziselwa iintsimbi ezithambileyo ezinje ngentsimbi ephantsi yentsimbi kunye ne-aluminium. Uyilo lwale Angle luhlala lungazizo, oko kuthetha ukuba akunakuphepheka ukuba ngumthi wokuhamba phambili. I-135 ° Emba i-till ye-till idla ngokuba nomsebenzi ozimeleyo. Kuba akukho sidingo sokuthi matshini umngxunya ophakathi, oku kuyakwenza ukuba kungafuneki ukuba kudlule umngxunya wayo ngokwahlukeneyo, ngaloo nto ukonga ixesha elininzi.

I-helix engle

I-helix engle engama-30 ° lukhetho olufanelekileyo kwizixhobo ezininzi. Kodwa kwiimeko ezifuna ukufuduswa okungcono kwe-chip kunye nomphetho oqinileyo oqinileyo, i-drill ene-angle encinci ye-helix inokukhetha. Kwizixhobo ezinzima-zoomatshini ezinje ngentsimbi engenasibala, uyilo olune-engix enkulu ye-helix inokukhethwa ukuba idlulise itota.
