Dab tsi yog HSS twist laum me ntsis?
HSS twist laum yog ib hom kev ua haujlwm drilling ua los ntawm cov hlau ceev steel siv rau kev ua hlau. HSS yog tshwj xeeb alloy steel nrog kev ua txhaum zoo heev, ua rau cov khoom siv hluav taws xob, ua rau cov khoom siv ua kom zoo nkauj rau cov haujlwm ua haujlwm xws li drilling. Ib rab riam laum (tseem hu ua auger lossis muab kauv flute tho) yog lub laum nrog cov chips tawm sai sai, txo kev sib txhuam thiab cua sov thaum drilling thiab txhim kho drilling efficiency. Tus tsim qauv ntawm HSS twist Laum ua rau lawv haum rau ntau cov ntaub ntawv hlau, suav nrog cov hlau sib txawv, suav nrog cov hlau thiab lwm yam zoo li ntoo hom machining.
Cov yam ntxwv ntawm cov tshuab ceev-ceev steel twist xyaum
1. Cov ntaub ntawv tsis txaus siab tiv thaiv: Cov txheej txheem ceev steel ua kom pom cov npoo zoo heev, tso cai rau cov kev txiav cov npoo mus txuas ntxiv rau ncua sijhawm.
2. Cov hlau kub muaj peev xwm ua kom muaj zog: high-ceev cov hlau tuaj yeem ua haujlwm nyob rau hauv cov kev kub-taws kub ib puag ncig yam tsis muaj qhov tsis zoo poob ntawm hardness lossis deformation.
3. Kev txiav kev nyab xeeb heev: Tus Kab zoom zig tsim ntawm Twist xyaum laum ua rau muaj cov hlau ua haujlwm thaum txo cov nti tsub zuj zuj.
4. Txhim kho machining zoo: high-ceev steel twist xyaum feem ntau dr drilling qhov ntev thiab du thaj chaw.
HSS hom peb tau siv rau peb cov kev xyaum sib tw
Cov qhab nia tseem ceeb ntawm HSS peb siv yog: M42, M42, M42, M25, M2, 4341, 4241.
Muaj qee qhov sib txawv ntawm lawv, tsuas yog cuam tshuam nrog lawv cov tshuaj muaj kuab lom, tawv tawv, ua kom ruaj khov thiab thaj chaw ntawm daim ntawv thov. Hauv qab no yog qhov sib txawv tseem ceeb ntawm cov qib HSS:
1. M42 HSS:
M42 muaj 7% -8% cobalt (CO), 8% Molybdenum (MO) thiab lwm yam alloys. Qhov no muab nws zoo zuj zus tua thiab thermal ruaj khov. M42 feem ntau muaj ntau lub hardness, thiab nws cov pob zeb hluav taws kub yog 67.5-70 (HRC) uas tuaj yeem ua tiav los ntawm kev kho cua sov.
2. M35 HSS:
M35 muaj 4.5% -5% cobalt thiab tseem muaj kev puas tsuaj loj tiv taus thiab ua kom ruaj khov. M35 yog qhov nyuaj dua li cov HSS thiab feem ntau tswj hwm lub hardness ntawm betwreeb 64.5 thiab 67.59 (HRC). M35 yog qhov tsim nyog rau kev txiav cov khoom nplaum xws li cov hlau stainless.
3. M2 HSS:
M2 muaj qib siab ntawm tungsten (w) thiab molybdenum (mo) thiab muaj cov khoom txiav zoo. Lub hardness ntawm M2 feem ntau yog nyob rau hauv thaj tsam ntawm 63.5-67 (HRC), thiab nws yog qhov tsim nyog rau lub machining cov hlau uas xav tau cov kev xav tau siab dua.
4. 4341 hss:
4341 HSS yog cov hlau ceev nrawm nrog cov ntsiab lus me me Alloy cov ntsiab lus ntsig txog M2. Lub hardness feem ntau tswj hwm saum 63 hrc thiab haum rau cov haujlwm dav hlau.
5. 4241 hss:
4241 hss kuj yog ib qho qis qis hss uas muaj cov ntsiab lus tsawg dua. Lub hardness feem ntau tswj ib ncig ntawm 59-63 hrc thiab feem ntau yog siv rau cov hlau ua haujlwm thiab tshuab ua haujlwm.
Xaiv cov qhab nia tsim nyog HSS nyob ntawm koj cov ntawv thov tshwj xeeb xav tau thiab cov khoom siv yuav tsum tau ua tiav. Hardness, puas tsis kam thiab thermal ruaj khov yog cov ntsiab lus tseem ceeb hauv kev xaiv.
