Uthotho: Kutheni ii-Drill Bits zingaphumeleli | Inqaku le-16
Amagama angundoqo: i-RPM yokubhola engalunganga, isantya se-drill bit, i-HSS drill bit RPM, isantya sokusika ukubhola, isantya sokubhola kunye nokutya, ububanzi be-drill bit kunye ne-RPM, isantya sokubhola sentsimbi engatyiwayo, i-feed per revolution, ukuguguleka kwe-drill bit, ukwaphuka kwe-drill bit, ukuqina komsebenzi wentsimbi engatyiwayo, kutheni ii-drill bits zingaphumeleli
I-drill inokungaphumeleli kwangethuba xa isantya sayo singahambelani nobubanzi bayo, umsebenzi kunye ne-feed. Useto oluluncedo lwe-RPM kufuneka lubotshelelwe kuzo zontathu. Ukujika nje umatshini ngokukhawuleza, okanye kancinci, akuqinisekisi umngxuma ongcono.
Eli nqaku ligxile kwiidrili ze-HSS ezijijekileyo ezisetyenziswa kwisinyithi. I-HSS ithetha intsimbi ekhawulezayo. Amaxabiso okubhekisa angezantsi achaza ubudlelwane; khetha useto lwemveliso kwidatha yedrili yokwenyani kunye nezinto.
1 Qonda isantya ngaphambi kokukhetha i-RPM
| Ixesha | Ithetha ukuthini |
| Isantya se-spindle n kwi-RPM | Zingaphi iinguqu ezenziwa yi-drill ngomzuzu ngamnye. |
| Isantya sokusika i-Vc kwi-m/min | Isantya somphetho wokusika kububanzi obungaphandle bokubhola. |
| Ububanzi D kwi mm | Sebenzisa ububanzi bokusika, hayi ububanzi obuncitshisiweyo bomqala. |
Kwi-RPM efanayo, i-drill enkulu inesantya esiphezulu sokusika esingaphandle. Kwi-1,000 RPM, i-drill eyi-10 mm isebenza malunga nesantya sokusika esiphindwe kathathu kune-drill eyi-3 mm. La ngamaxabiso abaliweyo, hayi useto olucetyiswayo.
Umfanekiso 1 I-RPM efanayo, isantya sokusika esahlukileyo. Ibalwe ukusuka kwi-Vc = πDn / 1000.
2 Isantya esiphezulu sinokunciphisa ubomi bokubhola
I-drill ingaphulukana nomphetho wayo ngaphambi kokuba iphuke. Isantya esiphezulu kunye nokutya okunganelanga kunokunciphisa ubomi besixhobo. Isantya esiphezulu singonakalisa neekona zangaphandle. Ukuhanjiswa kwesibandisi kunye nokukhetha i-drill nako kubalulekile.
Umphetho ogugileyo ungadinga amandla angakumbi ukuze uqhubeke usika. Ukuqhubeka nomsebenzi ngaphandle kokujonga umphetho kwaye inkqubo inokuguqula ingxaki yokuguguleka ibe yingxaki yokuqhekeka. Bhala phantsi indlela i-drill ehlulekile ngayo kunye nendawo eqale kuyo umonakalo ngaphambi kokuba uthathe isigqibo sokuba uza kutshintsha ntoni.
3 Ukucotha akusoloko kungcono
Isantya sokubhola esigqithisileyo nesinganeleyo sinokubangela ukwaphuka. Iidrill ezincinci ezenziwe ngentsimbi engagqwaliyo akufuneki ziqhutywe ngokuzenzekelayo kwi-RPM ephantsi kakhulu.
Kukwakho nengxaki yokufuya. Kumatshini ophethe i-feed kwi-mm/min, ukunciphisa i-RPM kunyusa umgama ohambileyo ngokujikeleza ngakunye ngaphandle kokuba useto lokufuya lutshintsha nalo. Umzekelo osebenzayo kwiiokulandelayo kubonisa isizathu sokuba oku kubalulekile.
Utshintsho lwesantya alunakulungisa into yokusebenza ekhululekileyo, umphetho owonakeleyo okanye iflute egcwele iitships. Ezo meko zifuna ukujongwa ngokwazo.
4 Intsimbi engagqwaliyo ifuna ukunqunyulwa okusebenzayo
Iintsimbi ezingenasici ze-Austenitic ezifana ne-304 kunye ne-316 zinokuqina ngexesha lokugrumba. Ukuqina komsebenzi kuthetha ukuqina okubangelwa kukuguquka kweplastiki. Akufanele kuchazwe nje njengobushushu obenza intsimbi ibe nzima.
Gcina ukutya okufanelekileyo kwaye uphephe ukuhlala okanye ukukhuhla ngelixa i-drill idibana nezinto ezisetyenzisiweyo. Iitships nazo kufuneka zikwazi ukuphuma emngxunyeni. Oku kufuna ubukhali, ukutya okufanelekileyo kunye nokususwa kweetships ngokufanelekileyo. Akuthethi ukusebenzisa amandla angenamkhawulo.
Ukuba i-drill iqhubeka nokujikeleza kwindawo enye ngaphandle kokuqhubela phambili okanye ukususa izinto, jonga iimeko zokusikwa kunye nemeko yomphetho. Ukuhlikihla ngokuphindaphindiweyo kunokwenza ukusika okulandelayo kube nzima ngakumbi. Musa ukuphendula ngokunyusa uxinzelelo ngaphandle kokufumana unobangela.
Oku kuthetha ukuthini xa kusenziwa
Phatha i-RPM njengenxalenye yenkqubo yokugrumba. Hlola isantya kunye nokutya, isibandisi kunye nokususwa kweetships. I-drill eyenziwe ngokuchanekileyo isafuna iimeko ezifanelekileyo zokusebenza; ingxaki yokusetyenziswa ayikuthinteli ukuba kubekho isiphene kwimveliso.
5 Isalathiso se-HSS sentsimbi engagqwaliyo
Uluhlu oluqhelekileyo lwereferensi yesantya sokusika se-HSS kwintsimbi engatyiwayo yi-30 ukuya kwi-50 iifithi zomphezulu ngomzuzu, okulingana ne-9.144 ukuya kwi-15.24 m/min. Itheyibhile engezantsi iguqula olo luhlu lube yi-RPM. Yisebenzise ukuqonda indlela ububanzi obuchaphazela ngayo isantya, uze ujonge useto lwe-drill kunye nezinto ezisetyenziswayo.
| Ububanzi bokubhola | Kwi-9.144 m/min | Kwi-15.24 m/min |
| 3 mm | 970 RPM | 1,617 RPM |
| 6 mm | 485 RPM | 809 RPM |
| 10 mm | 291 RPM | 485 RPM |
| 13 mm | 224 RPM | 373 RPM |
Itheyibhile 1 I-RPM ebaliweyo, ijikelezwe kwi-RPM epheleleyo ekufutshane. Ukuguqulwa: 1 ft = 0.3048 m.
Umfanekiso 2 Uluhlu olufanayo lwesantya sokusika lufuna i-RPM ephantsi njengoko ububanzi busanda. Ibhendi enombala luluhlu lwesalathiso olubaliweyo, alulo indawo yokusebenza ekhuselekileyo evavanyiweyo.
Olu luhlu olubanzi lwereferensi ye-HSS. Ayiboneleli ngokuseta okukhethekileyo kuyo yonke i-stainless grade, ubulukhuni, ukugquma okanye i-cobalt HSS drill. La maxabiso akangombono wemveliso yeJiacheng M35 okanye M42.
Sebenzisa idatha yomenzi wokugrumba kuqala. Jonga umgangatho wezinto kunye nemeko yazo, ubunzulu bomngxuma, isibandisi kunye namandla omatshini. Musa ukukopa itshati yesantya sekhabhayithi kwi-HSS drill.
6 Tshatisa i-RPM kunye ne-feed
I-feed per revolution fn ngumgama oqhutyelwe phambili yi-drill nge-turn enye, nge-mm/rev. Isantya se-feed Vf ngumgama oqhutyelwe phambili ngomzuzu omnye, nge-mm/min. Ulwalamano lwabo lulandelayo:
Vf= fnxn
Masithi umatshini ugcina isantya sokutya kwi-60 mm/min. Ukutshintsha i-RPM kuphela kuvelisa la maxabiso alandelayo. Lo ngumzekelo wezibalo, hayi isindululo sokubhola.
| Isantya se-spindle | Isantya sokutya | Ukutya ngokujikeleza ngakunye |
| 1,200 RPM | 60 mm/ngomzuzu | 0.05 mm/rev |
| 600 RPM | 60 mm/ngomzuzu | 0.10 mm/rev |
| 300 RPM | 60 mm/ngomzuzu | 0.20 mm/rev |
Itheyibhile 2 Ibalwe kusetyenziswa i-fn = Vf / n. Yonke imiqolo emithathu isebenzisa isantya esifanayo sokutya.
Umfanekiso 3 Xa i-feed iqiniswe kwi-60 mm/min, i-RPM iphinda kabini i-feed ngokujikeleza ngakunye. Ubude bebha bubonisa i-axial advance ngokujika ngakunye, hayi amandla okusika.
Ukunciphisa isantya ukusuka kwi-600 ukuya kwi-300 RPM kuphinda kabini i-advance nge-turn. Ukuba elo xabiso litsha liphezulu kakhulu kwi-drill kunye nokuseta, ukugqithisa kusenokuvela. Ukunyusa i-RPM ngelixa ubambe i-mm/min constant kunesiphumo esahlukileyo kwaye kunciphisa i-advance nge-turn.
Jonga indlela umatshini olawula ngayo ukutya. Xa ukutya kusetiwe kwi-mm/rev, umlawuli udla ngokutshintsha i-mm/min nge-RPM ukuze agcine i-advance ekhethiweyo ngokujika ngakunye. Qinisekisa imo esebenzayo kunye nokuziphatha komatshini ngaphambi kokulungisa useto.
Kwi-drill ephakelwa ngesandla, uxinzelelo alulolungiselelo lokuphakelwa olulinganisiweyo. Amaxabiso abaliweyo angasentla awanakuguqulelwa ngqo kwi-hand force ecetyiswayo.
7 Jonga iimeko ngaphambi kokuba utyhole i-RPM
Uphawu olunye lunokuba nezizathu ezahlukeneyo. Sebenzisa ezi tsheki zilandelayo ukukhokela uphando; itheyibhile ayichongi i-drill engaphumelelanga yodwa.
| Ingxaki eboniweyo | Iitshekhi eziza kubandakanywa |
| Ubomi bezixhobo obufutshane | Isantya, ukutya, ukukhetha i-drill kunye ne-coolant efikelela kwinqanaba. |
| Iikona zangaphandle ezonakeleyo | Isantya esigqithisileyo, isibandisi kunye neendawo eziqinileyo kwindawo yokusebenza. |
| Ukwaphuka ngequbuliso | Ukupakisha iitships, ukutya okuninzi, umphetho ogugileyo kunye nokubambelela okuqinileyo. |
| Umngxuma omkhulu kakhulu | Ukubeka i-point centering, imeko ye-spindle kunye nokuhamba kwe-workpiece. |
Kubathengi nakwabasasazi, bhala phantsi umgangatho wezinto kunye nemeko yazo, imodeli yokubhola kunye nobubanzi, ubunzulu bomngxuma, izixhobo, i-RPM yokusebenza, indlela yokutya kunye ne-coolant. Yongeza iifoto ezicacileyo zomphetho ophambili, iitships kunye necandelo elingasebenziyo. Oku kunika umthengisi ubungqina obuluncedo bokuthelekisa okufanelekileyo.
Ababoneleli bahlala benoxanduva lwezinto zokwakha, unyango lobushushu, ijiyometri kunye nokuhambelana kwebhetshi. Isikhokelo esicacileyo sokusetyenziswa sinceda abathengi ukuba baguqule loo mgangatho wemveliso ube kukusebenza kokugrumba okuphindaphindwayo.
