Uchungechunge: Kungani Ama-Drill Bits Ehluleka | Isihloko 16
Amagama angukhiye: i-RPM yokubhoboza engalungile, isivinini sebhithi lokubhoboza, i-HSS drill bit RPM, isivinini sokusika ukubhoboza, isivinini sokubhoboza kanye nokuphakelayo, ububanzi bebhithi lokubhoboza kanye ne-RPM, isivinini sokubhoboza sensimbi engagqwali, ukuphakela ngokujikeleza ngakunye, ukuguguleka kwebhithi lokubhoboza, ukuphuka kwebhithi lokubhoboza, ukuqina komsebenzi wensimbi engagqwali, kungani amabhithi okubhoboza ehluleka
I-drill ingahluleka kusenesikhathi uma ijubane layo lingahambisani nobubanzi bayo, umsebenzi kanye ne-feed. Isethingi ye-RPM ewusizo kumele iboshwe kuzo zontathu. Ukujika umshini ngokushesha, noma kancane, akuqinisekisi umgodi ongcono.
Lesi sihloko sigxile kuma-drill e-HSS twist asetshenziswa ensimbini. I-HSS isho insimbi esheshayo. Amanani okubhekisela ngezansi achaza ubudlelwano; khetha izilungiselelo zokukhiqiza kudatha ye-drill yangempela kanye nezinto.
1 Qonda isivinini ngaphambi kokukhetha i-RPM
| Ithemu | Kusho ukuthini |
| Isivinini se-spindle n ku-RPM | Ukujima kwenza izinguquko ezingaki ngomzuzu ngamunye. |
| Isivinini sokusika i-Vc ku-m/min | Ijubane lomkhawulo wokusika kububanzi bangaphandle bokubhoboza. |
| Ububanzi D ngo-mm | Sebenzisa ububanzi bokusika, hhayi ububanzi obuncishisiwe bomphetho. |
Ku-RPM efanayo, i-drill enkulu inesivinini sokusika esiphezulu esingaphandle. Ku-RPM eyi-1,000, i-drill engu-10 mm isebenza cishe ngesivinini sokusika esiphindwe ka-3.3 kune-drill engu-3 mm. Lawa amanani abaliwe, hhayi izilungiselelo ezinconywayo.
Umfanekiso 1 I-RPM efanayo, isivinini sokusika esihlukile. Kubalwe kusukela ku-Vc = πDn / 1000.
2 Isivinini esikhulu singanciphisa isikhathi sokubhoboza
I-drill ingase ilahlekelwe unqenqema lwayo ngaphambi kokuba iphuke. Isivinini esikhulu kanye nokudla okunganele kunganciphisa isikhathi sokuphila kwamathuluzi. Isivinini esikhulu singalimaza namakhona angaphandle. Ukulethwa kwesibandisi kanye nokukhetha i-drill nakho kubalulekile.
Unqenqema olugugile lungadinga amandla engeziwe ukuze luqhubeke nokusika. Ukuqhubeka nomsebenzi ngaphandle kokuhlola unqenqema futhi inqubo ingaguqula inkinga yokuguguleka ibe inkinga yokuphuka. Bhala phansi ukuthi i-drill yehluleke kanjani nokuthi umonakalo uqale kuphi ngaphambi kokunquma ukuthi yini okufanele uyishintshe.
3 Ukuhamba kancane akuhlali kungcono
Kokubili isivinini sokubhoboza ngokweqile nesinganele kungabangela ukuphuka. Ukubhoboza okuncane kwensimbi engagqwali akufanele kusebenze ngokuzenzakalelayo nge-RPM ephansi kakhulu.
Kukhona nenkinga yokuphakelwa. Emshinini ophethe ukuphakelwa ku-mm/min, ukwehlisa i-RPM kwandisa ibanga elithuthukisiwe ngokujikeleza ngakunye ngaphandle kokuthi ukusethwa kokuphakelwa kushintshe futhi. Isibonelo esisebenzayo ku-iokulandelayo kukhombisa ukuthi kungani lokhu kubalulekile.
Ukushintsha isivinini akukwazi ukulungisa umsebenzi okhululekile, unqenqema olulimele noma umtshingo ogcwele ama-chips. Lezo zimo zidinga ukuhlolwa kwazo.
4 Insimbi engagqwali idinga ukusikwa okusebenzayo
Izinsimbi ezingagqwali ze-Austenitic ezifana ne-304 kanye ne-316 zingasebenza kanzima ngesikhathi sokubhoboza. Ukuqina komsebenzi kusho ukuqina okubangelwa ukuguqulwa kwepulasitiki. Akufanele kuchazwe njengokushisa okwenza insimbi ibe nzima.
Gcina ukudla okufanele futhi ugweme ukuhlala noma ukuhlikihla ngenkathi i-drill ithintana nezinto. Ama-chips kumele akwazi ukuphuma emgodini. Lokhu kudinga unqenqema olubukhali, ukudla okufanele kanye nokususwa kwama-chip okuphumelelayo. Akusho ukusebenzisa amandla angenamkhawulo.
Uma i-drill iqhubeka nokujikeleza endaweni efanayo ngaphandle kokuthuthukisa noma ukususa izinto, hlola izimo zokusika kanye nesimo somphetho. Ukuhlikihla okuphindaphindiwe kungenza ukusika okulandelayo kube nzima kakhulu. Ungaphenduli ngokwandisa ingcindezi ngaphandle kokuthola imbangela.
Kusho ukuthini lokhu empeleni
Phatha i-RPM njengengxenye yenqubo yokubhoboza. Buyekeza isivinini kanye nokudla, i-coolant kanye nokususwa kwama-chip. I-drill eyenziwe kahle isadinga izimo zokusebenza ezifanele; inkinga yokusetshenziswa ayisusi iphutha lokukhiqiza.
5 Ireferensi ye-HSS yensimbi engagqwali
Ibanga elijwayelekile lokubhekisela kwesivinini sokusika se-HSS sensimbi engagqwali lingamafidi obuso angu-30 kuya kwangu-50 ngomzuzu, okulingana no-9.144 kuya ku-15.24 m/min. Ithebula elingezansi liguqula lelo banga libe yi-RPM. Lisebenzise ukuze uqonde ukuthi ububanzi buthinta kanjani isivinini, bese uhlola izilungiselelo ze-drill yangempela kanye nezinto zokwakha.
| Ububanzi bokubhoboza | Ku-9.144 m/min | Ku-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 |
Ithebula 1 I-RPM ebaliwe, ijikelezwe ku-RPM ephelele eseduze. Ukuguqulwa: 1 ft = 0.3048 m.
Umfanekiso 2 Ububanzi obufanayo besivinini sokusika budinga i-RPM ephansi njengoba ububanzi bukhuphuka. Ibhendi enomthunzi iyibanga lokubhekisela elibaliwe, akuyona indawo yokusebenza ephephile evivinyiwe.
Lolu uhla olubanzi lwereferensi ye-HSS. Ayinikezi isethingi enikezelwe kuyo yonke i-stainless grade, ubulukhuni, ukumboza noma i-cobalt HSS drill. Lawa manani akuzona izincomo zomkhiqizo we-Jiacheng M35 noma i-M42.
Sebenzisa idatha yangempela yomkhiqizi wokubhoboza kuqala. Hlola izinga lezinto kanye nesimo sazo, ukujula kwembobo, isibandisi kanye nekhono lomshini. Ungakopishi ishadi lesivinini se-carbide ku-HSS drill.
6 Qondanisa i-RPM nokuphakelayo
I-feed per revolution fn yibanga eliqhutshwa yi-drill ngokujika okukodwa, nge-mm/rev. Ijubane le-feed Vf yibanga eliqhutshwa ngomzuzu owodwa, nge-mm/min. Ubuhlobo babo buyi:
Vf= fnxn
Ake sithi umshini ubamba isivinini sokuphakelwa ku-60 mm/min. Ukushintsha i-RPM kuphela kukhiqiza amanani alandelayo. Lesi yisibonelo sezibalo, hhayi isincomo sokubhoboza.
| Isivinini se-spindle | Isivinini sokuphakelayo | Okuphakelayo ngokujikeleza ngakunye |
| 1,200 RPM | 60 mm/min | 0.05 mm/rev |
| 600 RPM | 60 mm/min | 0.10 mm/rev |
| 300 RPM | 60 mm/min | 0.20 mm/rev |
Ithebula 2 Libalwe kusetshenziswa i-fn = Vf / n. Yonke imigqa emithathu isebenzisa isivinini sokuphakela esifanayo.
Umfanekiso 3 Njengoba ukudla kuqiniswe ku-60 mm/min, ukuhlukaniswa kwe-RPM kabili kokudla ngokuzungeza ngakunye. Ubude bebha bubonisa ukuthuthuka kwe-axial ngokujika ngakunye, hhayi amandla okusika.
Ukunciphisa ijubane kusuka ku-600 kuya ku-300 RPM kuphinda kabili i-advance ngejika ngalinye. Uma lelo nani elisha liphezulu kakhulu kwi-drill kanye nokusetha, ukulayisha ngokweqile kusengenzeka. Ukuphakamisa i-RPM ngenkathi ubambe i-mm/min constant kunomphumela ophambene futhi kunciphisa i-advance ngejika ngalinye.
Hlola ukuthi umshini ulawula kanjani ukuphakelwa. Njengoba ukuphakelwa kusethwe ku-mm/rev, isilawuli sivame ukushintsha i-mm/min nge-RPM ukuze sigcine i-advance ekhethiwe ngokujika ngakunye. Qinisekisa imodi esebenzayo kanye nokuziphatha komshini ngaphambi kokulungisa izilungiselelo.
Ku-drill ephakelwa ngesandla, ingcindezi akuyona isethingi yokuphakelwa elinganisiwe. Amanani abalwe ngenhla awakwazi ukuguqulwa ngqo abe amandla esandla anconywayo.
7 Hlola izimo ngaphambi kokusola i-RPM
Uphawu olulodwa lungaba nezimbangela eziningana. Sebenzisa ukuhlola okulandelayo ukuze uqondise uphenyo; ithebula alizihloli zodwa izivivinyo ezihlulekile.
| Inkinga ebonwe | Amasheke okufanele afakwe |
| Impilo yamathuluzi emfushane | Isivinini, ukudla, ukukhetha ibhobo kanye nesipholile esifinyelela iphuzu. |
| Amakhona angaphandle alimele | Isivinini esikhulu, isibandisi kanye nezindawo eziqinile endaweni yokusebenza. |
| Ukuphuka okungazelelwe | Ukupakisha ama-chip, ukudla okweqile, unqenqema olugugile kanye nokubopha okuqinile. |
| Umgodi omkhulu kakhulu | Ukubeka iphuzu phakathi, isimo se-spindle kanye nokunyakaza kwezingxenye zomsebenzi. |
Kubathengi nabasabalalisi, qopha ibanga lezinto kanye nesimo sazo, imodeli yokubhoboza kanye nobubanzi, ukujula kwembobo, imishini, i-RPM yokusebenza, indlela yokuphakela kanye ne-coolant. Engeza izithombe ezicacile zomphetho osezingeni eliphezulu, ama-chips kanye nesigaba esihlulekile. Lokhu kunikeza umhlinzeki ubufakazi obuwusizo bokuqhathanisa okufanele.
Abahlinzeki bahlala benomthwalo wemfanelo ngezinto zokwakha, ukwelashwa kokushisa, i-geometry kanye nokuvumelana kweqoqo. Isiqondiso esicacile sokusetshenziswa sisiza amakhasimende ukuguqula leyo khwalithi yomkhiqizo ibe ukusebenza kokubhoboza okuphindaphindwayo.
Mayelana nalolu chungechunge
