Hauv ntiaj teb ua haujlwm hlau, qhov tseeb yog txhua yam. Ib qho ntawm cov lus nug feem ntau los ntawm cov neeg faib khoom thiab cov neeg siv kawg yog: "RPM yog dab tsi yog qhov tseeb rau kuv lub laum?" Kev teeb tsa qhov ceev yog qhov sib txawv ntawm lub qhov huv thiab lub cuab yeej puas lawm. Yog tias qhov ceev siab dhau, kev sib txhuam tsim cua sov ntau dhau, ua rau lub taub hau "kub hnyiab". Yog tias nws qis dhau, kev ua haujlwm poob qis, thiab koj yuav muaj kev pheej hmoo ntawm lub ntsis tawg vim muaj zog ntau dhau.
Nkag Siab Txog Cov Ntsiab Lus Tseem Ceeb: Kev Txiav Ceev vs. RPM
Ua ntej xam qhov ceev, koj yuav tsum nkag siab txog Qhov Ceev Txiav Vc. Qhov no sawv cev rau qhov ceev uas ntug txiav ntawm lub laum txav mus hla qhov chaw ntawm qhov khoom ua haujlwm.
Txawm hais tias Qhov Ceev Txiav yog txiav txim siab los ntawm cov khoom siv ntawm qhov workpiece, RPM (Revolutions Per Minute) yog qhov chaw koj tau kho qhov tseeb ntawm koj lub tshuab laum lossis CNC tshuab.
Cov Qauv lej rau Kev Ntsuas Tseeb
Yuav kom nrhiav tau qhov RPM tseeb uas xav tau rau koj txoj haujlwm tshwj xeeb, cov kws ua haujlwm engineers siv cov qauv txheem hauv qab no:
Cov Ntaub Ntawv Siv Txog Tus Qauv Kev Lag Luam
Cov ntaub ntawv hauv qab no yog raws li cov qauv kev tsim kho thoob ntiaj teb (xws li ISO 3685 thiab DIN 1414) rau High-Speed Steel (HSS). Cov nqi no ua haujlwm ua tus qauv thoob ntiaj teb rau kev nyab xeeb thiab kev ua haujlwm hlau.
Lub Tswv Yim Zoo: Thaum siv cov ntsis laum HSS-Co (Cobalt), feem ntau koj tuaj yeem ua kom qhov ceev no nce ntxiv 20% vim yog cov khoom siv tiv taus cua sov zoo dua.
3 Yam Tseem Ceeb Uas Cuam Tshuam Rau Koj Cov Txiaj Ntsig
Dhau ntawm tus qauv no, peb yam sab nraud yuav txiav txim siab koj txoj kev vam meej:
- Kev Tswj Kub thiab Lubrication
Kub yog tus yeeb ncuab tseem ceeb ntawm HSS. Kev siv roj txiav zoo lossis cov dej txias zoo tso cai rau koj ua haujlwm ntawm qhov kawg siab dua ntawm qhov ntau RPM pom zoo. Yog tsis muaj lubrication, koj yuav tsum nyob ntawm qhov kawg "muaj kev nyab xeeb" qis dua ntawm qhov ntsuas kom tiv thaiv cov hlau kom tsis txhob mos.
- Kev Tshem Tawm Chip (Txoj Kev "Peck")
Rau cov qhov tob, RPM yuav tsum tau sib npaug nrog kev tshem tawm cov chips. Yog tias cov chips (cov hlau curls) tsis tuaj yeem khiav tawm ntawm cov flutes, lawv yuav txhaws thiab ua kom lub ntsis kub dhau. Peb pom zoo kom "peck drilling" - rub lub ntsis rov qab tsis tu ncua kom tshem tawm cov khib nyiab.
- Kev Ruaj Ntseg Tshuab
Yog tias koj siv lub tshuab xuas tes tuav, ib txwm siv RPM qis dua li tus nqi uas tau xam. Cov cuab yeej tuav tes muaj kev co ntau dua thiab tsis ruaj khov dua li lub tshuab xuas ruaj khov, uas ua rau muaj kev pheej hmoo ntawm qhov ntsis "taug kev" lossis tawg.
Xaus lus
Siv RPM kom raug yog txoj hauv kev yooj yim tshaj plaws los txuas lub neej ntawm koj cov khoom Jiacheng Tools. Los ntawm kev ua raws li cov qauv thoob ntiaj teb no, koj xyuas kom meej tias koj cov khoom siv HSS tseem ntse, koj cov qhov tseem meej, thiab koj cov nqi tsim khoom tseem qis.
