Factors yuav xav txog:
Khoom siv:Cov cuab yeej siv yuav tsum muaj qhov tsim nyog hardness, toughness, thiab hnav tsis kam tiv thaiv lub zog thiab qhov kub thiab txias thaum lub sijhawm machining.
Tus nqi:Cov cuab yeej tuaj yeem yog tus nqi tseem ceeb, yog li tus nqi ntawm cov khoom siv thiab nws cov khoom muaj yog qhov tseem ceeb rau kev txiav txim siab.
Machineability:Qee cov khoom siv tau yooj yim dua rau lub tshuab dua lwm tus, uas tuaj yeem cuam tshuam rau lub sijhawm tsim khoom thiab cov nqi.
Txheej:Cov cuab yeej txheej tuaj yeem txhim kho kev ua tau zoo los ntawm kev txhim kho kev hnav tsis kam, txo kev sib txhuam, thiab ua kom lub neej ntev.
Lub neej cuab tam:Cov khoom siv yuav tsum tso cai rau lub neej ntev ntawm cov cuab yeej kom txo qis qis thiab hloov cov nqi.
Daim ntawv thov:Hom khoom siv ua tshuab (steel, aluminium, yas, thiab lwm yam) cuam tshuam rau kev xaiv cov khoom siv.
Common Tool Materials:
High-Speed Steel (HSS):Kev lig kev cai siv rau ntau yam kev siv vim nws zoo toughness thiab hnav tsis kam. Nws yog haum rau dav-purpose tej cuab yeej.
Cobalt-muaj HSS:Muab cov tawv tawv zoo dua qub thiab hnav tsis kam dua li HSS tus qauv, ua rau nws haum rau kev txiav nrawm dua thiab cov ntaub ntawv tawv dua.
Carbide (Cemented Carbide):Paub txog nws cov hardness siab thiab hnav tsis kam, carbide yog siv los txiav cov ntaub ntawv nyuaj thiab siv lub neej ntev dua ntawm kev nrawm dua.
Ceramics:Cov cuab yeej ceramic yog qhov nyuaj heev thiab muaj kev sib txhuam qis, ua rau lawv zoo tagnrho rau kev ua haujlwm siab ceev ntawm qee yam khoom xws li cam khwb cia hlau thiab cov hlau tsis muaj hlau.
Pob zeb diamond:Ntuj los yog hluavtaws pob zeb diamond cuab yeej siv rau machining non-ferrous hlau thiab non-metallic cov ntaub ntawv vim lawv hnyav hardness thiab hnav tsis kam.
Cubic Boron Nitride (CBN):Zoo ib yam li pob zeb diamond hauv hardness, CBN yog siv rau machining ferrous hlau, tshwj xeeb tshaj yog nyob rau hauv high speeds thiab roughing ua hauj lwm.
Polycrystalline Pob Zeb Diamond (PCD):Siv rau cov ntaub ntawv uas tsis yog-ferrous thiab muaj qhov zoo sib npaug ntawm hardness thiab thermal conductivity.
Silicon Nitride (Si3N4):Ib hom ceramic paub txog nws lub zog siab ntawm qhov kub thiab txias, ua rau nws haum rau high-speed machining.
Txheej txheem xaiv:
Txheeb xyuas cov khoom siv ua haujlwm:Hom khoom siv machined yog qhov tseem ceeb hauv kev xaiv cov khoom siv.
Txiav txim siab qhov kev ua haujlwm Machining:Kev ua haujlwm sib txawv (tig, milling, drilling, thiab lwm yam) yuav xav tau cov khoom siv sib txawv.
Xav txog cov xwm txheej txiav:Ceev, pub tus nqi, thiab qhov tob ntawm kev txiav tuaj yeem cuam tshuam rau kev xaiv cov khoom siv.
Ntsuam xyuas Tool Lub Neej thiab Kev Ua Haujlwm:Cov cuab yeej xav tau lub neej thiab qib xav tau ntawm kev ua tau zoo yog qhov tseem ceeb hauv cov txheej txheem xaiv.
Kev Ntsuas Tus Nqi-Cov txiaj ntsig:Txawm hais tias qee cov ntaub ntawv muaj kev ua tau zoo dua, lawv kuj tuaj yeem tuaj nrog tus nqi siab dua. Kev txheeb xyuas tus nqi-cov txiaj ntsig tuaj yeem pab nrhiav qhov sib npaug zoo tshaj plaws.
Kev xaiv cov khoom siv cuab yeej yog cov txheej txheem nyuaj uas yuav tsum muaj kev nkag siab tob ntawm ob qho tib si txheej txheem machining thiab cov ntaub ntawv koom nrog. Nws feem ntau yog cov txheej txheem rov ua dua uas suav nrog kev sim thiab kev ua kom zoo kom ua tiav cov txiaj ntsig zoo tshaj plaws rau ib daim ntawv thov tshwj xeeb.
