Ntau cov neeg siv khoom nug yuav nug dab tsi peb muaj?Cov txheej txheem ua li cas?Niaj hnub no los ntawm cov xov xwm no luv luv qhia cov khoom siv kais dej thiab txheej txheej.
1. Kais Khoom
Cov kais dej tso siab rau cov khoom siv ntau, thiab xaiv cov khoom zoo tuaj yeem ua kom zoo dua cov qauv ntawm cov kais dej, ua rau nws tsim nyog rau kev ua haujlwm zoo thiab xav tau ntau dua, thaum tseem muaj lub neej ntev dua.Tam sim no, cov tuam txhab lag luam loj muaj lawv tus kheej cov khoom lag luam lossis cov qauv tsim khoom, thiab vim yog cov peev txheej cobalt thiab cov nqi teeb meem, cov khoom siv cobalt tshiab tsis muaj kev ua haujlwm siab ceev steel kuj tau qhia.
1) Cov cuab yeej steel: Nws yog feem ntau siv rau tes txiav xov kais thiab tsis muaj ntau lawm.
2) Cobalt dawb high-speed steel: tam sim no dav siv los ua cov khoom siv kais dej, xws li M2 (W6Mo5Cr4V2, 6542), 4341, thiab lwm yam, cim nrog code HSS.
3) Cobalt uas muaj cov hlau ceev: tam sim no dav siv los ua cov khoom siv kais dej, xws li M35, M42, thiab lwm yam., cim nrog tus lej HSS-E.
4) hmoov metallurgy high-speed steel: siv los ua cov khoom siv ua haujlwm siab, nws qhov kev ua tau zoo tau zoo dua qub piv rau ob qho saum toj no, thiab cov npe ntawm txhua qhov chaw tsim khoom kuj txawv, nrog rau cov cim code yog HSS-E-PM .
5) Cov khoom siv tawv tawv: feem ntau xaiv nrog cov khoom siv ultrafine thiab zoo toughness, feem ntau yog siv rau kev tsim cov groove ncaj kais ua cov ntaub ntawv luv luv, xws li grey cam khwb cia hlau, siab silicon aluminium, thiab lwm yam.
Peb lub tuam txhab tsuas yog tsim HSS-M2, HSS-4341, HSS-E cov ntaub ntawv.
2. Kais Txheej
Cov txheej txheem ntawm cov kais dej muaj qhov cuam tshuam loj rau kev ua haujlwm ntawm cov kais dej, tab sis tam sim no, feem ntau yog cov chaw tsim khoom thiab cov chaw tsim tshuaj pleev ib ce uas sib koom ua ke los kawm cov txheej txheem tshwj xeeb.
1) Chav oxidation: Cov kais dej tau muab tso rau hauv cov dej kub kub los ua ib txheej ntawm oxide zaj duab xis ntawm nws qhov chaw, uas muaj qhov zoo adsorption ntawm lub coolant thiab tuaj yeem txo kev sib txhuam, thaum tiv thaiv adhesion ntawm cov kais dej thiab cov khoom raug txiav.Nws yog tsim rau kev ua cov hlau mos.
2) Nitriding kev kho mob: Qhov saum npoo ntawm cov kais dej yog nitrided los ua ib txheej txheej tawv tawv, haum rau kev ua cov ntaub ntawv xws li cam khwb cia hlau thiab cam khwb cia txhuas uas muaj kev hnav tsis kam rau cov cuab yeej txiav.
3) Chav + Nitriding: Muab qhov zoo ntawm ob qho saum toj no.
4) TiN: Golden daj txheej, nrog zoo txheej hardness thiab lubrication, thiab zoo txheej adhesion kev ua tau zoo, haum rau kev ua cov ntaub ntawv feem ntau.
5) TiCN: Xiav grey txheej, nrog lub hardness ntawm kwv yees li 3000HV thiab kub tsis kam mus txog 400 ° C.
6) TiN + TiCN: sib sib zog nqus daj txheej nrog zoo heev txheej hardness thiab lubrication, haum rau kev ua cov khoom siv feem ntau.
7) TiAlN: Blue grey txheej, hardness 3300HV, tshav kub tsis kam mus txog 900 ° C, haum rau high-speed machining.
8) CrN: Silver grey txheej nrog lubrication kev ua tau zoo, feem ntau yog siv rau kev ua cov hlau tsis muaj hlau.
Peb lub tuam txhab tsuas yog tsim Chav oxidation, Nitriding kho, TiN, TiCN, TiAlN txheej.
