Uchungechunge:Kungani Ama-Drill Bits Ehluleka | Isihloko 3
Amagama angukhiye:Ikhwalithi yebhithi lokubhoboza le-HSS, isisindo sebhithi lokubhoboza, ubulukhuni bebhithi lokubhoboza, ukuminyana kwe-HSS, ukuhlolwa kwekhwalithi yebhithi lokubhoboza, indlela yokuhlola amabhithi okubhoboza
Abanye abathengi bakala izingcezu zokubhoboza lapho behlola amasampula omhlinzeki omusha. Uma ingxenye isinda, kulapho insimbi iba ngcono khona — noma kunjalo ukucabanga kuyahamba.
Kuyisimo esiqondakalayo. Isisindo sizwakala njengesimelelo sento ebalulekile. Kodwa uma kukhulunywa ngama-drill bits e-HSS, isisindo singenye yezinkomba ezingathembeki kakhulu zekhwalithi. Kwezinye izimo, i-drill bit enzima empeleni iyisibonakaliso somkhiqizo osezingeni eliphansi.
Nasi isizathu.
Ubuningi be-HSS abushintshi kakhulu phakathi kwamabanga
I-High Speed Steel iwumndeni othize wezinsimbi zamathuluzi ezichazwa yizakhi zayo zokuxuba — i-tungsten, i-molybdenum, i-chromium, i-vanadium, kanye ne-cobalt grades. Lezi zakhi zengezwa ngamaphesenti amancane ukulawula ubulukhuni, ukumelana nokuguguleka, kanye nobunzima obubomvu.
Ubuningi be-HSS kuwo wonke amamaki avamile — i-M2, i-M35, i-M42 — bungaphansi kobubanzi obuncane, cishe bungu-8.1 kuya ku-8.3 g/cm³. I-M2 ne-M35 ziyahlukahluka ngokuqukethwe kwe-cobalt (0% uma kuqhathaniswa no-5%), kodwa ubuningi be-cobalt (cishe u-8.9 g/cm³) busondele ngokwanele ku-matrix yensimbi eyisisekelo ehlanganisa u-5% wayo ku-alloy ishintsha ubuningi obuphelele ngaphansi kuka-0.1 g/cm³. Lowo mehluko awubonakali ngesandla futhi awubalulekile ngisho nasesikalini sokunemba.
Ngokwendlela engokoqobo: awukwazi ukusebenzisa isisindo ukuhlukanisa i-M2 ne-M35, noma i-HSS ejwayelekile ne-HSS yezinga le-cobalt.
Pho kungani ezinye izingcezu zokubhoboza zizwakala zinzima?
Uma izingcezu ezimbili zokubhoboza ezinobukhulu obufanayo zizwakala zihlukile kakhulu ngesisindo, incazelo cishe njalo iwukuba yi-geometry — hhayi izinto ezibonakalayo.
Isisindo sento yokubhoboza sinqunywa ukuthi iqukethe izinto ezingakanani. Ngobude nobubanzi obunikeziwe, okubalulekile ukuthi ingakanani insimbi esusiwe ngesikhathi sokugaya. I-geometry yombhobho — ukujula nobubanzi beziteshi ezilengayo ezisikiwe emzimbeni — kulawula lokhu ngqo. Imibhobho ejulile nebanzi isusa izinto eziningi. Imibhobho engajulile ishiya okuningi.
Umkhiqizi angakhiqiza i-drill bit enzima ngokugaya ama-flute angajulile. I-bit igcina izinto eziyinhloko ezengeziwe, ngakho-ke inesisindo esikhulu. Kodwa ama-flute angajulile anemiphumela: ukususwa kwama-chip kuba nzima ukusebenza kahle, ukusika ukungqubuzana kuyanda, futhi ukushisa kwakheka ngokushesha endaweni yokusika. Ezintweni ezinzima noma eziphakelweni eziphezulu, lokhu kuholela ekugugeni okusheshayo kanye nengozi ephezulu yokwehluleka kusenesikhathi.
Lokhu kusho ukuthi i-drill bit esindayo akuyona i-drill bit engcono. Kungaba nje indawo lapho kwasikwa khona ikona ngokwejiyometri - futhi umthengi uphambanisa uphawu nophawu lwekhwalithi.
Lokho Okufanekiswa Yisisindo Ngempela
Isisindo sibonisa ubukhulu bensimbi esele. Ubuningi bulawulwa ngokugaya. Ikhwalithi yokugaya iyisinqumo sokukhiqiza.
Umkhiqizi onolwazi ugaya ama-flute ngokwe-geometry echazwe uhlelo lokusebenza — i-DIN 338 noma amazinga alinganayo achaza i-engeli ye-helix, ukujula kwe-flute, kanye ne-geometry yephuzu ngesizathu. Lezi zilinganiso zilungiselelwe phakathi namashumi eminyaka okusetshenziswa kwezimboni ukuze kulinganiswe ukuphuma kwe-chip, amandla asezingeni eliphezulu, kanye nokusebenza kahle kokubhoboza.
I-drill bit ephambuka ku-geometry ejwayelekile ukuze ibonakale inzima kakhulu ayithuthukanga kuleyo bhalansi. Iyibekile engcupheni.
Izilinganiso Ezibalulekile Ngempela
Uma isisindo singeyona inkomba ethembekile, yini okufanele abathengi bayibheke lapho behlola ikhwalithi ye-drill bit?
Izinguquko ezinengqondo yilezi:
•Ubulukhuni.Ngemva kokwelashwa ngokushisa, umkhawulo ophambili we-M2 HSS drill bit ekhiqizwe kahle kufanele ufinyelele cishe ku-HRC 63–65. I-M35 cobalt kufanele ifinyelele ku-HRC 64–66. Amanani okuqina ngaphandle kwala mabanga abonisa izinkinga ngokwelashwa ngokushisa — kungaba ukushisa okunganele, izinga lokucima elanele, noma ukulawula okungahambi kahle kokushisa. Ukuqina kungalinganiswa ngqo ngesihloli sokuqina kweRockwell.
•Ukwakheka kwezinto.Ukuhlaziywa kwe-Spectrometer (OES — Optical Emission Spectrometry) kuyindlela ethembekile yokuqinisekisa ukuthi i-drill bit iqukethe yini izakhi ze-alloy ezifunwayo. Okuqukethwe kwe-Cobalt, iphesenti le-tungsten, i-vanadium — akukho nokukodwa kwalokhu okubonakalayo noma okungalinganiswa. Kudinga ukuqinisekiswa kwelebhu.
•Ukunemba kwejiyometri.I-engeli yephoyinti, i-engeli ye-helix, ukulingana kombhobho, kanye nesimo somphetho we-chisel konke kuthinta ukusebenza kokusika. Lokhu kuyalinganiswa ngamathuluzi okulinganisa okukhanya noma amaphrojektha ephrofayili.
•Ukuvumelana kweqembu.Isampula eyodwa edlulayo ayanele. Abathengi bezimboni badinga ukusebenza okugcina yonke inqwaba yokukhiqiza. Ukuvumelana kobulukhuni, i-geometry, kanye nokuphela kobuso phakathi kwamakhulu noma izinkulungwane zezingcezu kungumbuzo wenqubo yokukhiqiza, hhayi umbuzo wokuhlolwa kweyunithi eyodwa.
•Ukuqeda ubuso.Ikhwalithi yokugaya iyabonakala. Amamaki okugaya aqinile, izindawo zombhobho ezingalingani, noma amamaki okukhuluma abonakalayo onqenqemeni oluphambili kuyizimpawu zezinkinga zenqubo. I-drill bit egayiwe kahle ikhombisa izindawo zombhobho ezihlanzekile, ezibushelelezi ezine-geometry yonqenqema ehambisanayo.
Lokhu Kusho Ukuthini Ngezinqumo Zokuthola Imithombo
Uma umhlinzeki ethumela amasampula, gwema ukuthambekela kokuwahlola ngesisindo. Ukuhlola okunenjongo ukucela isitifiketi sezinto ezibonakalayo, ukuhlola i-geometry ngaphansi kokukhulisa uma kungenzeka, kanye - ngama-oda aphezulu - ukucela idatha yokuhlola ubulukhuni noma ukuqinisekiswa kwezinto ezizimele.
Isisindo asiyona indlela emfushane. Siwumsindo.
Ikhwalithi ye-HSS drill bit itholakala ekwakhekeni kwayo kwensimbi, ukwelashwa kwayo ngokushisa, kanye nokwakheka kwayo komhlabathi. Akukho nokukodwa kwalokhu okubonakala esikalini.
Mayelana Nalolu Hlelo
Kungani Ama-Drill Bits Ehluleka uchungechunge lobuchwepheshe oluvela eqenjini lethu lokukhiqiza. Isihloko ngasinye sigxile esicini esisodwa ekusebenzeni kwama-drill bit — kusukela ezintweni zokusetshenziswa kuya ekupakisheni. Umgomo ulula: ukusiza abathengi baqonde ukuthi bathengani ngempela, nokuthi yimiphi imibuzo efanele ukubuzwa.
