Chitsulo chosapanga dzimbiri ndi chimodzi mwa zinthu zofunika kwambiri kuboola. Mosiyana ndi chitsulo chofewa kapena aluminiyamu, chimawononga luso loipa komanso kugwiritsa ntchito zipangizo molakwika mwachangu komanso moonekera bwino — kudzera m'zidutswa zosweka, mabowo akuluakulu, ndi malo otsetsereka. Bukuli likufotokoza chifukwa chake chitsulo chosapanga dzimbiri chimachita zinthu momwe chimachitira, komanso tanthauzo lake posankha chobowola choyenera, kukhazikitsa magawo oyenera, ndikusunga khalidwe logwirizana pakupanga.
Chifukwa chiyani chitsulo chosapanga dzimbiri chimakhala chovuta kuboola
Kumvetsa vutoli kumayamba ndi zinthu zomwezo. Chitsulo chosapanga dzimbiri — makamaka magiredi a austenitic monga 304 ndi 316 — chili ndi zinthu ziwiri zomwe zimapangitsa kuti kuboola kukhale kovuta kwambiri kuposa zitsulo zina zambiri.
Kulimbitsa ntchito
Chitsulo chosapanga dzimbiri chikakumana ndi mphamvu ya makina — kuphatikizapo mphamvu zodulira kuchokera ku chobowolera — zinthu zomwe zili pamalo odulira zimalimba mofulumira. Izi zimatchedwa kuuma kwa ntchito, ndipo zimachitika mofulumira m'magawo osapanga dzimbiri a austenitic kuposa pafupifupi zinthu zina zonse zodziwika bwino zaukadaulo.
Mwachidule, izi zikutanthauza kuti: ngati chobowolera chayima, chachedwa, kapena kukanda m'malo modula bwino, pamwamba pa chobowoleracho chimalimba mkati mwa masekondi. Chodulira chotsatira chimakumana ndi gawo lolimba kuposa lomwe lidalipo kale. Izi zimapangitsa kuti chida chiziwonongeka kwambiri ndipo, ngati sichinakonzedwe, zimapangitsa kuti ntchito ikhale yolimba kwambiri m'dzenjemo - zomwe zimapangitsa kuti ntchitoyo ikhale yovuta kwambiri pamene ikupita patsogolo.
Kutentha kochepa
Chitsulo chosapanga dzimbiri sichitentha bwino poyerekeza ndi chitsulo chofatsa kapena aluminiyamu. Pakuboola, kudula kumabweretsa kutentha kwakukulu. Mu chinthu chomwe chili ndi kutentha kwabwino, kutentha kwakukulu kumatengedwa ndi workpiece ndi tchipisi. Mu chitsulo chosapanga dzimbiri, kutentha kumakhala kokhazikika m'mphepete mwa chodulira.
Kuphatikiza kwa kuuma kwa ntchito ndi kuchuluka kwa kutentha kumabweretsa vuto lowonjezereka: pamene chobowolera chikutentha, kuuma kwake m'mphepete mwachitsulo kumayamba kuchepa. Mphepete yofewa imadula pang'ono bwino, imapanga kukangana kwambiri, imapanga kutentha kwambiri - ndipo kayendedwe kake kamapitirira mpaka chobowoleracho chitalephera.
Kusankha chobowola choyenera: M2 vs M35
Chinthu chimodzi chofunikira kwambiri pakuboola chitsulo chosapanga dzimbiri ndi choboolera. Njira ziwiri zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale ndi chitsulo champhamvu cha M2 ndi M35. Kumvetsetsa kusiyana pakati pa izi ndikofunikira kwambiri kuposa momwe ogula ambiri amaganizira.
Chitsulo cha M2 chothamanga kwambiri
M2 ndi mtundu wamba wa chitsulo chothamanga kwambiri komanso chinthu chobowola chomwe chimapangidwa kwambiri padziko lonse lapansi. Kapangidwe kake — pafupifupi 6% ya tungsten, 5% ya molybdenum, 4% ya chromium, ndi 2% ya vanadium — kamapangitsa kuti ikhale yolimba, yolimba, komanso yogwira ntchito bwino pazinthu zosiyanasiyana.
Cholepheretsa cha M2 pa ntchito ya chitsulo chosapanga dzimbiri ndi kuuma kwake kotentha, komwe kumatchedwanso kuuma kofiira. Izi zikutanthauza kuthekera kwa chinthu kusunga kuuma kwake kutentha kwambiri. M2 imayamba kutaya kuuma kwake bwino pa kutentha kwa pafupifupi 550–600°C. Mu kuboola chitsulo chosapanga dzimbiri — makamaka m'malo opangira kapena pamene kuzizira sikukwanira — kutentha kwamakono nthawi zambiri kumapitirira malire awa.
Mphepete ikafewa, imasiya kudula ndikuyamba kukanda. Kukangana kumawonjezeka, kutentha kumawonjezeka kwambiri, gawo lolimba lomwe limagwiritsidwa ntchito limakhala lovuta kulowa, ndipo moyo wa zida umachepa kwambiri. Kulephera sikuchitika mwadzidzidzi nthawi zonse - nthawi zambiri kumawonekera ngati kumverera kolemera pang'onopang'ono kwa chakudya, kuwonjezeka kwa kuphulika mozungulira potulukira pa dzenje, komanso kuwonongeka kwa kukula kwa dzenjelo lisanathe.
Chitsulo champhamvu cha M35 cobalt
M35 imagwiritsa ntchito kapangidwe kofanana ndi ka M2 ndi kuwonjezera pafupifupi 5% ya cobalt. Cobalt sichita nawo mwachindunji kudula - sipanga ma carbide kapena kuwonjezera kuuma pa kutentha kwa chipinda mwanjira iliyonse yofunikira. Ntchito yake makamaka ndikukhazikitsa matrix yachitsulo pa kutentha kwambiri, kukweza malo omwe kuuma kumayamba kuwonongeka.
M35 imasunga kuuma kothandiza mpaka pafupifupi 630–650°C. Kusiyana kwa 50–80°C poyerekeza ndi M2 kungawoneke ngati kochepa, koma moyo wa zida umakhudzidwa kwambiri ndi kutentha kwamtunduwu. Mu mayeso oyerekeza olamulidwa pa chitsulo chosapanga dzimbiri cha austenitic, M35 nthawi zambiri imapanga mabowo ochulukirapo kawiri kapena katatu kuposa M2 pansi pa mikhalidwe yofanana - ndipo nthawi zambiri kwambiri pamene ntchitoyo ikuphatikizapo kudula kosalekeza, kuchuluka kwa chakudya chosiyanasiyana, kapena kuzizira kosakwanira.
Kwa ogula, kufananiza kwachuma ndikosavuta: M35 bits imadula kwambiri pa unit, koma mtengo pa bowo lomwe labowoledwa - chifukwa cha kuchuluka kwa ma replacement, nthawi yomwe makina sagwira ntchito, komanso kuchuluka kwa ma retract kuchokera ku mabowo otsika - nthawi zambiri kumakhala kotsika poyerekeza ndi momwe chitsulo chosapanga dzimbiri chimagwirira ntchito.
Pamene M2 ikadali yovomerezeka
M2 si yoyenera kugwiritsidwa ntchito pa chitsulo chosapanga dzimbiri. Pansi pa izi, imatha kugwira ntchito mokwanira:
•Liwiro lotsika lodula ndi choziziritsira madzi chambiri
•Kuboola pang'onopang'ono komanso kotsika kwambiri komwe kumakhala ndi nthawi yozizirira pakati pa mabowo
•Zipangizo zopyapyala (≤3mm) pomwe chobowoleracho chimakhudzana ndi chogwirira ntchito kwa kanthawi kochepa
•Pamene zoletsa za mtengo zimapangitsa kuti M35 isagwire ntchito komanso kuti kulekerera kwa mabowo kukhale kwakukulu
Pakupanga zinthu zambiri, pa zinthu zokhuthala, kapena pamene kulondola kwa miyeso n'kofunika kwambiri, M35 ndiye chisankho chodalirika kwambiri.
Kudula liwiro ndi kuchuluka kwa chakudya
Ngakhale ndi zinthu zolondola, magawo odulira olakwika angayambitse kulephera msanga. Zinthu ziwiri zoyendetsera ndi liwiro lodulira (lomwe limafotokozedwa ngati liwiro la pamwamba mu m/min, kapena kusinthidwa kukhala RPM kuti likhale ndi mainchesi enaake) ndi liwiro la chakudya (momwe kubowola kumayendera mofulumira pa kuzungulira kulikonse).
Kudula liwiro
Pa chitsulo chosapanga dzimbiri, liwiro loyenera la pamwamba pa ma HSS drill bits ndi lotsika kwambiri kuposa la chitsulo chofewa. Malangizo onse a austenitic grades (304, 316):
•M2 HSS: Liwiro la pamwamba pa 10–15 m/mphindi
•M35 cobalt HSS: Liwiro la pamwamba pa 15–25 m/mphindi
Izi zimasanduka RPM monga: RPM = (liwiro la pamwamba × 1000) ÷ (π × m'mimba mwake wa kubowola mu mm). Chidutswa cha 10mm M35 mu chitsulo chosapanga dzimbiri cha 316, cholunjika 20 m/min, chimagwira ntchito pa pafupifupi 637 RPM.
Kuthamanga mofulumira kwambiri ndi cholakwika chofala kwambiri pobowola chitsulo chosapanga dzimbiri. Kuthamanga kwambiri kumapanga kutentha mofulumira kuposa momwe choziziritsira chimachichotsera komanso mofulumira kuposa momwe chip chingachinyamulire. Chidutswacho chimatentha kwambiri, chimataya kuuma kwa m'mphepete, ndipo chimalephera msanga. Ogwiritsa ntchito omwe amazolowera kubowola chitsulo chofewa kapena aluminiyamu nthawi zambiri amagwiritsa ntchito chosapanga dzimbiri pa liwiro lomwe ndi lalikulu kawiri kapena katatu kuposa momwe chimakhalira.
Chiŵerengero cha chakudya
Kuchuluka kwa chakudya kuyenera kukhala kokwanira kuti chidutswacho chizidula mosalekeza m'malo mokanda. Chakudya chopepuka kwambiri chimalola chidutswacho kuyenda pamwamba pa chinthu cholimba popanda kulowa - kupanga kutentha popanda kuchotsa zinthu. Ichi ndiye chifukwa chachikulu cha kuuma kwa ntchito msanga m'dzenje.
Mitengo yofunikira yodyetsera chitsulo chosapanga dzimbiri (pa kuzungulira kulikonse): 0.05–0.10 mm pa zidutswa mpaka 5mm m'mimba mwake; 0.10–0.20 mm pa 5–15mm; 0.20–0.35 mm pamwamba pa 15mm. Izi ndi malo oyambira — sinthani kutengera kapangidwe ka chip komwe kawonedwa, phokoso lodula, ndi kutentha pa nsonga ya kubowola.
Chizindikiro chodalirika kwambiri chakuti magawo ake ndi olondola ndi chip. Chip yopyapyala, yopindika bwino imasonyeza kudula koyenera. Chip yayitali, yopyapyala imasonyeza kuti chakudya chake ndi chopepuka kwambiri. Chip yophwanyika kapena yosinthika mtundu wake imasonyeza kutentha kwambiri.
Choziziritsira ndi mafuta odzola
Choziziritsira sichosankha pobowola chitsulo chosapanga dzimbiri. Ntchito yake ndi iwiri: kuchotsa kutentha pamalo odulira, ndi kudzola mafuta pakati pa zitoliro za bit flutes ndi khoma la dzenje kuti achepetse kutentha komwe kumapangidwa ndi kukangana.
Choziziritsira madzi (mafuta osungunuka osakanikirana pafupifupi 8–10%) ndi njira yothandiza kwambiri pamakina ndi zida. Pa kuboola ndi manja kapena kuboola popanda choziziritsira madzi, madzi odulira ogwiritsidwa ntchito mwachindunji pa chidutswa ndi polowera musanayambe kuboola komanso panthawi yoboola ndi ofunikira. Kuboola chitsulo chosapanga dzimbiri kuyenera kupewedwa kulikonse komwe ubwino wa dzenje kapena moyo wa chida ndi wofunika.
Choziziritsira chiyenera kufika pamalo odulira. Choziziritsira chakunja chomwe chimasefukira pazida zogwirira ntchito zokhuthala (zopitirira 15–20mm) sichingaziziritse bwino nsonga ya bit - nthawi zina, kugwiritsa ntchito zida zoziziritsira kapena kubweza bit nthawi ndi nthawi kuti zichotsedwe ndikulola kuziziritsa ndikofunikira.
Jiyomethri ndi ngodya ya mfundo
Ma drill bits okhazikika a point 118° apangidwa kuti agwiritsidwe ntchito nthawi zonse. Pa chitsulo chosapanga dzimbiri, mawonekedwe a point point 135° ndi othandiza kwambiri pazifukwa ziwiri.
Choyamba, mfundo yogawanika imachotsa m'mphepete mwa chisel womwe uli pazidutswa zokhazikika zophwanyika. M'mphepete mwa chisel simudula - umakankhira ndi kukanda, ndikupanga kutentha popanda kuchotsa tchipisi. Kuchotsa kumatanthauza kuti chidutswacho chimayamba kudula nthawi yomweyo chikakhudzana, zomwe zimachepetsa kutentha koyamba komanso chizolowezi choyenda pansi.
Chachiwiri, ngodya yocheperako ya 135° imagawa mphamvu zodulira mofanana pa milomo yodulira, kuchepetsa katundu pa gawo lililonse ndikuwonjezera kulimba kwa zidutswa muzinthu zolimba kapena zogwirira ntchito.
Pa ntchito zambiri zobowola zitsulo zosapanga dzimbiri, chobowola cha M35 cobalt cha 135° split-point ndiye njira yoyenera yoyambira.
Kukhazikitsa ndi kugwira ntchito
Kulimba kwa makinawo n'kofunika kwambiri ndi chitsulo chosapanga dzimbiri kuposa zinthu zofewa. Kugwedezeka kulikonse kapena kupatuka kulikonse pakati pa chidutswa ndi chogwirira ntchito kumapangitsa kuti chidutswacho chizikanda pang'onopang'ono m'malo modula mosalekeza, zomwe zimapangitsa kuti ntchito ikhale yolimba komanso kuti m'mphepete mwake musamawonongeke.
Zipangizo zogwirira ntchito ziyenera kukhala zomangiriridwa mwamphamvu, osati zogwiritsidwa ntchito ndi manja. Chobowoleracho chiyenera kufufuzidwa kuti chizigwiritsidwa ntchito bwino musanagwiritse ntchito - ngakhale zochepa zomwe zimayikidwa bwino zimathandiza kuti milomo yodulayo isawonongeke mofanana.
