High Precision Yas CNC Machining Qhov Chaw
Dab tsi yog qhov tshwj xeeb ntawm cov khoom sib txawv CNC?
CNC machining tuaj yeem tsim cov khoom los ntawm yuav luag txhua yam hlau lossis yas.Cov yam ntxwv ntawm kev txaus siab ntawm cov ntaub ntawv no yog:
1. mechanical zog: qhia los ntawm tensile yield zog;
2. machinability: qhov yooj yim ntawm machining influences tus nqi ntawm CNC;
3. tus nqi ntawm cov khoom siv;
4. hardness: tsuas yog rau cov hlau;
5. kub tsis kam: feem ntau yog rau cov yas.
CNC hlau
Cov ntawv thov uas xav tau lub zog siab, hardness, thiab thermal kuj siv hlau los yog, theej, hlau alloys.
1.Aluminium: siv los tsim kev cai hlau qhov chaw thiab cov qauv.
2.Stainless hlautuaj yeem yooj yim welded, machined, thiab polished.
3.Me me hlau, los yog tsawg-carbon steel: siv rau tshuab qhov chaw, jigs, thiab fixtures.
4.Hlau alloymuaj lwm yam alloying ntsiab ntxiv nrog rau cov carbon los txhim kho hardness, toughness, qaug zog, thiab hnav tsis kam.
5.Cov cuab yeej steelyog qhov zoo rau fabrication cov cuab yeej xws li tuag, stamps, thiab pwm.
6.tooj dagyog qhov zoo tagnrho rau cov ntawv thov uas yuav tsum muaj kev sib txhuam qis thiab kev tsim vaj tsev los tsim cov khoom kub zoo nkauj rau lub hom phiaj zoo nkauj.
CNC yas
Plastics yog cov khoom siv sib txawv nrog lub cev sib txawv, feem ntau siv rau lawv cov tshuaj tiv thaiv thiab cov yam ntxwv ntawm hluav taws xob rwb thaiv tsev.
1.ABS: feem ntau siv los tsim cov qauv ua ntej ntau lawm los ntawm kev txhaj tshuaj molding.
2.Nylon, los yog polyamide (PA): Feem ntau yog siv rau kev siv vim nws cov khoom siv kho tshuab zoo heev, cuam tshuam lub zog, thiab kev ua haujlwm siab rau tshuaj thiab puas.
3.Polycarbonateyog feem ntau optically pob tshab, ua rau nws zoo tagnrho rau ntau daim ntawv thov, xws li cov kua dej los yog automotive glazing.
POM (Delrin) yog cov khoom xaiv rau CNC machining thaum cov khoom xav tau:
1. siab precision
2. siab rigidity
3. kev sib txhuam qis
4. zoo heev dimension stability ntawm qhov kub thiab txias
5. nqus dej tsawg heev.
PTFE (Teflon) muaj kev tiv thaiv kev ua haujlwm kub siab tshaj 200 ° C thiab yog li ntawd, ib qho hluav taws xob zoo insulator.
High-density polyethylene (HDPE) yog tsim rau siv sab nraum zoov thiab kav.
PEEK: feem ntau yog siv los hloov cov khoom hlau vim nws lub zog-rau-qhov hnyav piv.Cov qib kho mob kuj muaj, ua PEEK kuj tsim nyog rau kev siv biomedical.
CNC Composite cov ntaub ntawv
Composites, hauv cov ntsiab lus yooj yim, yog ntau yam khoom siv nrog cov yam ntxwv sib txawv ntawm lub cev thiab tshuaj lom neeg uas sib xyaw ua ke los tsim kom muaj zog, sib zog, los yog qee zaum cov khoom hloov tau yooj yim dua.
Ib qho ntawm qhov zoo tshaj plaws-paub composites nyob rau hauv kev ua lag luam yogreinforced yas.Niaj hnub no, yas yog siv nyob rau hauv ib tug ntshiab daim ntawv nyob rau hauv feem ntau cov khoom, xws li nyob rau hauv cov khoom ua si thiab lub raj mis dej.Txawm li cas los xij, nws tuaj yeem txhawb nqa nrog fibers los ntawm lwm cov ntaub ntawv.Cov txheej txheem no ua rau qee qhov muaj zog tshaj plaws, lightest, thiab ntau yam sib xyaw muaj.
Ib qho kev siv ntawm cov khoom sib xyaw yog los txhawb cov khoom siv purer nrog fiber ntau los ntawm lwm cov ntshiab los yog cov khoom sib xyaw.Cov neeg tsim khoom feem ntau yuav ntxivcarbon los yog graphite fibersmus rau ib qho kev sib xyaw.Cov pa roj carbon fibers yog cov khoom siv hluav taws xob, muaj kev sib xyaw ua ke zoo kawg nkaus ntawm cov qauv siab thiab lub zog tensile, muaj qhov qis heev (me ntsis tsis zoo) CTE (coefficient ntawm thermal expansion), thiab muaj kev tiv thaiv zoo rau qhov kub thiab txias.Cov yam ntxwv no ua rau cov pa roj carbon zoo heev rau ntau lub lag luam, thiab nws yooj yim fuses nrog ntau cov ntaub ntawv.
Ntxiv nrog rau cov pa roj carbon,fiberglassyog ib qho khoom siv fiber ntau zoo.Fiberglass tsis muaj zog lossis nruj li cov pa roj carbon fiber ntau, tab sis nws muaj cov yam ntxwv tshwj xeeb uas ua rau nws xav tau hauv ntau daim ntawv thov.Cov iav fiber ntau yog nonconductive (piv txwv li, ib qho insulator) thiab feem ntau pom tsis tau rau ntau hom kev sib kis.Qhov no ua rau nws xaiv zoo rau kev siv hluav taws xob lossis kev tshaj tawm.
Resinsyog ib qho tseem ceeb ntawm cov khoom sib xyaw.Lawv yog cov matrices uas tuav cov ntaub ntawv sib cais ua ke yam tsis muaj lawv raug fused rau hauv ib qho khoom ntshiab.
