Cas ua cua sov txhim kho cnc-machining qhov chaw?

Kev kho cua sov yog ib qho kev kho cua sov tau thov rau cov hlau hluav taws xob rau cov cua sov kom sov, thiab lub sijhawm nyob ua ke.

Cov kev txwv no tseem ceeb tshaj plaws lub cev cov khoom kawg ntawm machined Cheebtsam, ua rau cov kev siv rau engineering.

CNC Machining Kev Txhim Kho Cua sov

Txhim kho cov khoom siv mechanical

 Hardness & Hnav Kuj: Ua tiav qhov chaw ua kom ruaj khov rau lub zog, kev ua cuab yeej, lossis cov khoom sib txhuam siab.

 Zog-qhov hnyav piv: Txhim kho cov qauv kev ntseeg nyob rau hauv Aerospace lossis alloys alloys (piv txwv li aluminium {{t6).

 Ductility & machinility: Cov ntaub ntawv muag muag ua ntej-machining (piv txwv li, annealing) los txo cov khoom hnav thiab txhim kho kev tsim cov cim.

 Kev ntxhov siab nyem: Tshem tawm sab hauv kev ntxhov siab los ntawm CNC cov txheej txheem (piv txwv li, txiav) los tiv thaiv deformation.

Micruction Kev Tswj

Phase hloov pauv (piv txwv li, martensite hauv hlau) thiab tshuaj diffusion (piv txwv li, carburizing) Refine Land qauv qauv rau kev ua tau zoo.

 Cov khoom siv tau:Aluminium vs. steel xav tau cov kev cai txawv (piv txwv li, t6 tempering vs. roj quenching).

 Part Geometry:Nyias-walled lossis cov duab sib xyaw yuav xav tau nqus cua sov kom txo qis distortion.

 Kev xav tau kev ua tau zoo:Ua ntej Hardness (HRC / HRB), nkees tsis kam, lossis corrosion thev taus.

 Tus nqi efficiency:Sib npaug rau tom qab kev kho mob kev kho mob machining xav tau (piv txwv li, kev sib tsoo cov chaw tawv).

 Ua ntej machining: Annealing / softening kom yooj yim CNC txiav ntawm nyuaj alloys.

 Ncej-Machining: Zaum kawg ua rau kev laus / kev laus kom tau raws li qhov tsis muaj kev cuam tshuam qhov tseeb.

 Cov haujlwm thib ob: Muab sib txuas nrog cov kev kho kom ncaj (piv txwv li, anodizing) rau ntau yam sib xyaw.

1, annealing, ntxhov siab lug thiab kev kub ntxhov

Annealing, Tempering, thiab kev ntxhov siab kev ntxhov siab yog cov txheej txheem kho cua sov siv los kho cov khoom siv hlau tshuab ntawm cov hlau alloys. Thaum txhua tus koom nrog rau kev kub kub kom nce qhov kub (500-1, 200 degree), lawv cov laj thawj qeeb (huab cua lossis huab cua sib txawv.

Annealing yog ib txoj kev kho cua sov uas cov hlau (piv txwv li, txhuas, nyob ntawm alloy) thiab maj mam txias (cua sov) kom ua tiav cov kev hloov pauv microstruction microstructural.

Kev ntxhov siab kev ntxhov siab yog lub hom phiaj kho cua sov uas cov khoom siv kub kom sov rau thaum lub sijhawm tsim khoom (piv txwv li, machining, lossis sib sau ua). Cov kauj ruam no yog qhov tseem ceeb rau kev tsim cov khoom nrog cov cuab yeej siv cov khoom siv zoo ib yam, tshwj xeeb tshaj yog nyob rau hauv high-precision kev lag luam zoo li lub tshuab hluav taws xob.

Tempering kuj kub dua qhov chaw ntawm qhov kub qis dua li annealing thiab feem ntau yog siv tom qab quenying ntawm cov hlau me (1045 thiab AR36) thiab alloy hlau (4240). Qhov no txo ​​nws tus brittleness thiab txhim kho nws cov khoom siv neeg kho tshuab.

2, harden los ntawm quenching

Quenching yog cov txheej txheem kev kho cua sov uas muaj hlau (piv txwv li cov cuab yeej siv hluav taws xob (roj av) thiab txias) thiab txias dua (}

Vim li cas quench tom qab cnc machining?

✅ Ncej-Machining Hardening: Thov raws li cov kauj ruam kawg kom tsis txhob ua workpiece embrittlementlim thaum lub sij hawm txiav
✅ Tool Steel AShancement: A2 cuab tam Hlau tiav 63-65 hrc tom qab quenching (thiab 22-25 hrc hauv annealed xeev)
✅ Kev tswj qhov seem: Minimizes distortion thaum ua rau tag nrho cov khoom siv tau

3, Nag los daus tawv

Nag ua daus hardening (tseem hu ua hnub nyoog nyuaj siv tau siv los ntxiv dag zog cov hlau alloys los ntawm kev sib sau Nanoscale precipitates nyob rau hauv tus qauv crystal. Tus txheej txheem no tau siv dav rau txhuas, hlau stainless, thiab titanium alloys rau cov ntawv thov siab.

4, cov txheej txheem hardening thiab carburizing

Cov txheej txheem hardening yog lub tshav kub kho kom muaj kev tiv thaiv kev kub ntxhov ntawm cov hlau sab nraud sab nraud thaum tswj hwm tus tseem ceeb. Qhov no tau ua tiav los ntawm kev qhia cov roj carbon, nitrogen, lossis lwm cov khoom rau saum npoo los ntawm cov txheej txheem xws li carburizing, nitring, lossis induction hardening.

 Kev Siv Nyiaj Siv Kev Siv Nyiaj Txiag: Txo cov nqi hloov pauv hauv ib cheeb tsam muaj kev ntxhov siab siab.

 Tsim qauv tsim: Pab kom lub teeb yuag tsis muaj zog tsis muaj zog.

 Kev ceev kev cai: Ua raws li cov qauv kev lag luam (piv txwv li, ASTM, Ams, ISO) rau cov ntawv thov tseem ceeb.
