CNC Niobium machined qhov chaw polished nto
Niobium paub txog nws qhov nyuaj machinability vim nws lub zog siab, ductility thiab thermal conductivity tsawg. Kev ua niobium yuav tsum muaj cov cuab yeej tshwj xeeb, cov txheej txheem thiab cov txheej txheem kom ua tiav cov txiaj ntsig raug.
Qee qhov kev txiav txim siab tseem ceeb rau niobium machinability suav nrog:
1. Cov cuab yeej: Vim lub siab hardness ntawm niobium, carbide los yog pob zeb diamond cov cuab yeej feem ntau yog siv los ua niobium. Cov cuab yeej no tuaj yeem tiv taus qhov hnav thiab tsim kua muag ntawm niobium thiab tuav lawv txoj kev txiav ntev dua.
2. Txiav ceev thiab pub: Niobium muaj cov thermal conductivity tsawg thiab txiav ceev thiab pub yuav tsum tau ua tib zoo xav kom tsis txhob overheating thiab cov cuab yeej hnav. Kev xaiv kom raug ntawm kev txiav tsis yog qhov tseem ceeb kom ua tiav cov khoom tshem tawm kom zoo yam tsis muaj kev cuam tshuam lub neej ntawm cov cuab yeej.
3. Lubrication: Siv cov kua txiav kom tsim nyog lossis cov roj nplua nyeem yog qhov tseem ceeb los txo kev sib txhuam thiab kub thaum lub tshuab ua haujlwm. Qhov no pab txhim kho qhov chaw tiav thiab txuas ntxiv lub neej ntawm cov cuab yeej.
4. Workpiece clamping thiab fixtures: Kev nyab xeeb workpiece clamping thiab fixtures yog ib qho tseem ceeb rau kev txo qis kev co thiab ua kom muaj kev ruaj ntseg thaum lub sij hawm machining, tshwj xeeb tshaj yog thaum machining me me los yog complex niobium qhov chaw.
5. Cov txheej txheem tom qab ua tiav: Cov txheej txheem tom qab ua tiav xws li electrolytic polishing lossis chemical etching tuaj yeem siv los txhim kho qhov chaw tiav thiab tshem tawm cov kev ntxhov siab uas tshwm sim thaum lub sijhawm ua haujlwm.
Muab cov kev cov nyom ntawm niobium machining, nws yog ib qho tseem ceeb uas yuav tsum tau ua hauj lwm nrog cov kws paub txog kev siv tshuab thiab siv cov cuab yeej CNC machining siab heev kom ua tiav qhov raug thiab qhov zoo uas yuav tsum tau muaj rau niobium machined qhov chaw.
Yog, niobium yog malleable. Nws muaj ductility zoo thiab tuaj yeem yooj yim molded rau hauv ntau yam duab tsis muaj cracking. Qhov ductility no ua rau niobium haum rau cov ntawv thov uas xav tau kev tsim thiab tsim, xws li kev tsim cov hlau, ntawv, thiab lwm yam khoom siv.
Yog lawm, niobium yog cais raws li cov hlau refractory. Refractory hlau yog ib pawg ntawm cov hlau uas muaj cov cua sov zoo heev thiab cov ntsiab lus melting siab, ua rau lawv tsim nyog siv rau hauv cov ntawv thov kub. Niobium, uas muaj lub siab melting point thiab zoo heev kub-kub kuj, ntog rau hauv qeb no thiab feem ntau yog siv nyob rau hauv aerospace, high-temperature alloys thiab high-temperature processing industries vim nws cov hluav taws-resistant zog.
