Simbi yakakwirira-yakasimba inowedzerwa nehuwandu hwakasiyana hwezvinhu zvealloying musimbi.Mushure mekupisa kupisa, iyo alloying zvinhu zvinosimbisa iyo yakasimba mhinduro, uye iyo metallographic chimiro kazhinji martensite.Iyo ine simba rakakura uye kuomarara kwepamusoro, uye kuomarara kwayo kwakakwira zvakare kupfuura 45 simbi.Simba rekucheka panguva yekucheka richava 25% -80% yakakwirira kudarika simba rekucheka rekucheka 45, iyo yakakwirira yekucheka tembiricha ndeye, uye yakaoma chip breaking.Saka, mukugadzirwa chaiko, simbi dzakasimba dzinocheka sei?
1. Chishandiso
Pakucheka uye kukanganiswa kucheka, chishandiso chinodiwa kuti ive nekupisa kwekuvhunduka.Pamusoro pemidziyo yedhaimondi, marudzi ese ezvishandiso anogona kutemwa.Paunosarudza zvishandiso zvekushandisa, zvinofanirwa kusarudzwa maererano nemamiriro ekucheka.
A. High speed simbi
Kusarudzwa kwesimbi yepamusoro-yepamusoro-yepamusoro-yekucheka yakakwirira-simba uye ultra-yakakwirira-yakasimba simbi inofanira kunge yakavakirwa pane zvivakwa, chimiro, nzira yekugadzira uye kuomarara kwemaitiro ehurongwa, uye kunyatso funga nezve kupisa kupisa, kupfeka kusagadzikana uye. kuoma kwezvinhu zvekushandisa.Kana iyo process system ine yakanyanya kuomarara uye chishandiso chimiro chiri nyore, tungsten-molybdenum-yakavakirwa, yakakwira-kabhoni yakaderera-vanadium-ine aluminium yakakwirira-kumhanya simbi kana tungsten-molybdenum-yakavakirwa yakakwira-carbon low-vanadium yakakwira-cobalt yakakwira- kumhanya simbi inogona kushandiswa;pasi pesimba rekucheka mamiriro, tungsten-molybdenum inogona kushandiswa.High vanadium high speed simbi.
B. Powder metallurgy high speed simbi uye Tin coated high speed simbi
Powder metallurgy high-speed simbi ihuru-nokukurumidza hupfu iyo yakananga yakatsikirirwa pakupisa kwepamusoro uye kumanikidzwa kwepamusoro, uye yobva yaumbwa muchimiro chinodiwa chekushandisa.Iyo inorodzwa mushure mekugadzirisa uye ine yakanyanya kuoma uye yakakwirira kupfeka kusagadzikana.Iyo yakakodzera kune yakakwirira-simba simbi uye super.Kucheka kwesimbi yakakwirira-yakasimba.
C. Cemented carbide
Cemented carbide ndicho chinhu chikuru chekushandisa chekucheka yakakwirira-simba uye ekupedzisira-yepamusoro-simba simbi.Kazhinji, mitsva yepamusoro-inoshanda yakaoma alloys kana coated hard alloys inofanira kusarudzwa.
D. Ceramic mapanga
Kuomarara kwayo uye kushorwa kwekupisa kwakakwira kupfuura iyo yakaoma alloys, ichibvumira kucheka kumhanya 1-2 nguva yakakwirira kupfuura simende carbides.Mukucheka kwesimbi yakasimba-yakasimba uye ye-ultra-high-simba simbi, zvigadziro zveceramic zvinonyanya kushandiswa mushizha rekushanda uye kunyatsogadzira machining.
2. Kucheka huwandu
Iyo yekucheka kukurumidza kutendeuka yakakwirira-yakasimba simbi inofanira kunge iri 50% -70% yakaderera pane yekucheka kukurumidza kwesimbi yakawanda.Iyo yakakwirira simba uye kuoma kwezvinhu zvekushanda, iyo yakaderera kukurumidza kwekucheka kunofanira kuva.Kucheka kumhanya kwesimbi yakakwirira-yakasimba kucheka simbi yakasimba ndeye (3-10) m/min, carbide tool (10-60) m/min, ceramic tool is (20-80) m/min, CBN tool is (40). —220) m/maminitsi.Kudzika kwekucheka uye kudya kwakafanana neyekutenderera kwesimbi.
3. Chip kuputsa nzira
Pamusana pesimba repamusoro-soro resimbi yakasimba, hazvisi nyore kuputsa chip panguva yekutendeuka, izvo zvinounza kuoma kukuru kwekufamba kwakatsetseka kwekutendeuka.Izvo zvinodikanwa kubhadhara zvakanyanya kune izvi mukugadzirisa.
