HSS Twist Drill Bit Yog Dab Tsi?
Lub tshuab tho qhov ntswj HSS yog ib hom cuab yeej tho qhov uas ua los ntawm cov hlau ceev ceev uas siv rau kev ua hlau. HSS yog cov hlau sib xyaw tshwj xeeb uas muaj kev tiv taus kev sib txhuam zoo heev, kev ruaj khov thermal, thiab cov yam ntxwv txiav, ua rau nws zoo tagnrho rau cov haujlwm ua hlau xws li kev tho qhov. Lub tshuab tho qhov ntswj (tseem hu ua auger lossis spiral flute drill) yog lub tshuab tho qhov uas muaj helical flutes uas tso cai rau kev txiav cov chips tawm ntawm qhov tho qhov sai sai, txo kev sib txhuam thiab cua sov thaum lub sijhawm tho qhov thiab txhim kho kev ua haujlwm drilling. Kev tsim cov tshuab tho qhov ntswj HSS ua rau lawv haum rau ntau yam khoom siv hlau sib txawv, suav nrog hlau, txhuas, tooj liab thiab alloys, thiab lwm yam nrog rau kev ua haujlwm hom ntoo.
Cov Yam Ntxim Saib Ntawm Cov Tshuab Drills Hlau Ceev Ceev
1. Kev Tiv Thaiv Kev Sib Txhuam Siab: Cov khoom siv hlau ceev ceev ua rau muaj kev tiv thaiv kev sib txhuam zoo heev, ua rau cov npoo txiav tseem ntse rau lub sijhawm ntev.
2. Kev Ruaj Khov Kub Siab: Cov hlau ceev ceev tuaj yeem ua haujlwm hauv qhov chaw kub siab yam tsis muaj kev poob ntawm qhov nyuaj lossis kev hloov pauv.
3. Kev Ua Haujlwm Zoo Tshaj Plaws: Tus qauv tsim ntawm cov laum ntswj pab txhawb rau kev txiav hlau zoo thaum txo cov chips sib sau ua ke.
4. Kev Siv Tshuab Zoo: Cov tshuab laum hlau ceev ceev feem ntau xa cov qhov zoo uas muaj qhov loj me thiab cov nto du.
Cov Hom HSS Peb Siv Rau Peb Cov Twist Drills
Cov qib tseem ceeb ntawm HSS peb siv yog: M42, M35, M2, 4341, 4241.
Muaj qee qhov sib txawv ntawm lawv, feem ntau yog hais txog lawv cov tshuaj lom neeg muaj pes tsawg leeg, qhov nyuaj, kev ruaj khov thermal thiab thaj chaw siv. Hauv qab no yog qhov sib txawv tseem ceeb ntawm cov qib HSS no:
1. M42 HSS:
M42 muaj 7% -8% cobalt (Co), 8% molybdenum (Mo) thiab lwm yam alloys. Qhov no ua rau nws zoo dua qub thiab thermal stability. M42 feem ntau muaj qhov nyuaj dua, thiab nws qhov rockwell hardness yog 67.5-70 (HRC) uas tuaj yeem ua tiav los ntawm cov txheej txheem kho cua sov.
2. M35 HSS:
M35 muaj 4.5% -5% cobalt thiab kuj muaj kev tiv taus kev sib txhuam zoo thiab kev ruaj khov thermal. M35 nyuaj dua li HSS ib txwm muaj thiab feem ntau tswj tau qhov nyuaj ntawm 64.5 thiab 67.59 (HRC). M35 yog qhov tsim nyog rau kev txiav cov khoom nplaum xws li hlau tsis xeb.
3. M2 HSS:
M2 muaj cov tungsten (W) thiab molybdenum (Mo) ntau thiab muaj cov yam ntxwv txiav zoo. Qhov nyuaj ntawm M2 feem ntau yog nyob rau hauv qhov ntau ntawm 63.5-67 (HRC), thiab nws yog qhov tsim nyog rau kev siv cov hlau uas xav tau cov kev cai siab dua.
4. 4341 HSS:
4341 HSS yog cov hlau ceev ceev uas muaj cov ntsiab lus alloy qis dua me ntsis piv rau m2. Qhov nyuaj feem ntau yog khaws cia siab tshaj 63 HRC thiab tsim nyog rau cov haujlwm ua hlau dav dav.
5. 4241 HSS:
4241 HSS kuj yog HSS uas tsis muaj hlau ntau uas muaj cov khoom sib xyaw tsawg dua. Qhov nyuaj feem ntau tswj tau nyob ib puag ncig 59-63 HRC thiab feem ntau yog siv rau kev ua haujlwm hlau dav dav thiab kev khawb.
Kev xaiv qib HSS kom raug yog nyob ntawm koj qhov kev xav tau tshwj xeeb thiab hom khoom siv uas yuav tsum tau ua. Qhov nyuaj, kev tiv taus kev sib txhuam thiab kev ruaj khov thermal yog cov yam tseem ceeb hauv kev xaiv.
