HSS, cobalt, thiab carbide khoom feem ntau txawv ntawm cov khoom, hardness/heat resistance, nqi, thiab zoo tshaj - siv cov ntaub ntawv. Hauv kev xyaum, HSS yog rau kev ua haujlwm dav dav, cobalt yog rau cov hlau tawv, thiab carbide yog rau cov ntaub ntawv nyuaj tshaj plaws / feem ntau abrasive.
HSS (High -Speed Steel):
Ua los ntawm cov cuab yeej hlau hlau (feem ntau nrog cov ntsiab lus xws li chromium, vanadium, thiab lwm yam), nyuaj tab sis kuj tawv thiab tsis nkig heev.
Cobalt (HSS{0}}Co): Qhov tseem ceeb HSS nrog txog 5-8% cobalt ntxiv, nce hardness thiab kub-lub zog tab sis kuj ua rau me ntsis nkig.
Carbide: Feem ntau cov khoom tungsten carbide los yog carbide-tipped, nyuaj dua li cov hlau-raws li cov khoom thiab khaws cov npoo ntse ntawm qhov kub thiab txias, tab sis tseem muaj zog dua.
HSS bits:
Zoo tshaj plaws rau ntoo, yas, thiab me me / qis-carbon steels thiab lwm yam hlau mos
Zoo "lub hom phiaj dav" xaiv rau tsev thiab lub khw muag khoom siv qhov twg koj tsis thawb nrawm lossis txiav cov alloys nyuaj.
Cobalt khoom:
Tsim los rau cov tawv tawv, tawv tawv xws li stainless hlau, cam khwb cia hlau, titanium, thiab ntau cov hlau tawv tawv, tshwj xeeb tshaj yog nyob rau hauv repetitive lossis ntau lawm drilling.
Feem ntau siv thaum tshav kub kub buildup siab vim lawv khaws hardness thiab txiav peev xwm ntawm kub siab dua tus qauv HSS
Carbide khoom:
Siv rau cov ntaub ntawv nyuaj los yog abrasive: hardened steels, cam khwb cia hlau, composites, ceramics, pob zeb, pob zeb, thiab masonry (feem ntau yog carbide-tipped percussion / rauj laum khoom).
Feem ntau hauv CNC thiab kev teeb tsa kev lag luam uas rigidity thiab siab spindle speeds txo qhov kev pheej hmoo ntawm chipping.
Durability, brittleness, thiab nqi
HSS:
Tus nqi qis tshaj plaws, yooj yim tshaj plaws los kho dua tshiab, thiab ntau dua kev zam txim ntawm kev ua tsis zoo los yog tes drilling vim tias nws yog qhov nyuaj thiab tsis tshua muaj siab rau chipping, tab sis nws dulls sai dua hauv kev ua haujlwm hnyav / kub.
Cobalt:
Ntau ruaj dua HSS hauv cov hlau tawv thiab kub kub, nyob twj ywm ntev dua, tab sis kim dua thiab nkig, yog li cov npoo nti yooj yim dua yog tias tsim txom.
Carbide:
Kev hnav lub neej ntev tshaj plaws thiab ua haujlwm kub zoo tshaj plaws, tab sis tus nqi siab tshaj plaws thiab feem ntau nkig; poob siab, sab-load, lossis sib tham tuaj yeem snap lossis nti me ntsis sai
Cov lus xaiv ceev
| Drill ntsis hom | Cov khoom siv tseem ceeb & qhov zoo | Cov ntaub ntawv zoo tshaj plaws | Pros | Cons |
|---|---|---|---|---|
| HSS | Alloy cuab yeej steel; tawv, nruab nrab hardness thiab kub tsis kam. cov | Ntoo, yas, txhuas, me me hlau, dav DIY. cov | Pheej yig, ntau yam, zam txim, yooj yim rau resharpen. cov | Dulls sai dua hauv cov hlau tawv / abrasive; qis kev ua haujlwm kub kub. cov |
| Cobalt (HSS-Co) | HSS nrog ~ 5-8% cobalt; nyuaj, ntau cua sov resistant, me ntsis brittle. cov | Stainless hlau, cam khwb cia hlau, titanium, hardened steels. cov | Zoo heev hauv cov hlau tawv, tuav ntug ntawm qhov kub siab, zoo rau kev tsim khoom drilling. cov | Ntau nkig; tus nqi siab dua. cov |
| Carbide | tungsten carbide (feem ntau nrog cobalt binder); nyuaj heev, kub resistant, nkig. cov | Hardened steels, abrasive composites, masonry, pob zeb, pob zeb. cov | Lub neej ntev tshaj plaws, ua kom ntse ntug ntawm kev kub ceev / cua sov, txiav cov ntaub ntawv lwm tus tsis tuaj yeem. cov | Yooj yim heev; xav tau kev teeb tsa nruj; kim tshaj plaws. cov |
Txoj cai yooj yim - ntawm - tus ntiv tes xoo xaiv
Siv HSS yog tias koj tab tom ua qhov dav dav hauv cov ntoo, yas, lossis cov hlau me me thiab xav tau tus nqi qis thiab zam txim rau tus cwj pwm.
Kauj Ruam mus rau cobalt thaum koj niaj hnub xyaum stainless lossis lwm yam hlau tawv thiab tsim kom muaj cua sov ntau
Siv cov carbide thaum cov khoom tsis tshua muaj zog / abrasive los yog koj muaj kev teeb tsa nruj thiab xav tau kev ceev tshaj plaws thiab lub neej cuab yeej txawm tias tus nqi siab dua thiab brittleness.
