Nyob rau hauv cov cheeb tsam heev, Cheebtsam xws liLub Cav Rotor Coops, Tsaws Iav Cov Kabmob Rooj Zaum, thiab lwm qhov tseem ceeb Aerospace ntu yog raug rau siab - zaus, hloov kev ntxhov siab. Cov khoom no ua ib lub luag haujlwm tseem ceeb hauv kev tswj hwm txoj kev ncaj ncees thiab kev nyab xeeb, tshwj xeeb hauv kev thauj khoom thiab thauj mus los mus. Raws li qhov tshwm sim, tswjDaj qaug zog tawgUa qhov tseem ceeb rau kev tswj kev ua haujlwm kom muaj kev cia siab ua haujlwm thiab txuas ntxiv rau lub neej ntawm cov khoom ntawd.
Qhov kev sib tw
Ib qho ntawm cov kev sib tw tseem ceeb tshaj plaws hauv kev siv cov khoom siv no yog kev tswj hwmThaj Chaw Muaj Kev Thaj Chaw Zoo, uas yog qhov ua rau tawg tau dhau lub sijhawm. Cov chaw no yuav tsum muaj:
Tsawg kawg nkaus nto roughnessTxhawm rau zam kev pib nkees tawg.
Residual Kev Nyuaj SiabTxhawm rau txhim kho cov khoom siv tsis kam rau kev hais tawm sai.
Ua tiav cov yam ntxwv no, tshwj xeeb tshaj yog nyob rau hauv high - kev muaj kev ntxhov siab thaj chaw, ua rau ib qho nyuaj tshaj plaws hauv kev ua haujlwm ntawm cov khoom siv tseem ceeb tshaj plaws.
Peb txoj kev daws teeb meem
Txhawm rau kom cov cheeb tsam ntsib kev ua kom muaj zog ua ke, kev sib xyaw ntawm kev sib xyaw tshuab nthuav dav thiab tshaj tawm {{txheej txheej yog siv:
Precision tig
Peb ua haujlwm siab - precisionCNC Rawskom ua tiav qhov yuav tsum tau uaNto tasnrog tus nqi ra tsawg heev (tsawg dua 0.2 μm). Cov kauj ruam no ua kom muaj kev ntxhib tseem ceeb uas tsis muaj qhov sib luag uas tuaj yeem ua qhov pib rau kev ua haujlwm nkees.
Tua puab tsaig
Rau ntxiasResidual Kev Nyuaj SiabNyob rau hauv cov txheej saum npoo, peb thovtua puab tsaigmus rau cov machined Cheebtsam. Qhov txheej txheem no txhim kho lub zog qaug zog los ntawm kev tiv thaiv kev tawg pleb pib thiab kev loj hlob hauv cov khoom seem.
Nano {-} polishing
Tom qab txhaj clening, cov khoom sib xyawThaum kawg nano -} polishingkom ua tiav cov ultra -} du nto. Cov txheej txheem no ntxiv txo qis txoj kev pheej hmoo ntawm kev tawg thiab txhim kho cov khoom sib xyaw ua haujlwm tas.

Los ntawm kev sib txuasPrecision tig, tua puab tsaig, thiabnano {-} polishingrau hauv aPuas muaj ntau -} theem txheej txheem, peb paub tseeb tias txhua qhov ntawm kev nkees sab saum npoo tsis kam yog hais los ntawm pib kom tiav.
Qho kawg

|---|---|---|
| Nto roughness (ra) | Ra> 0.8 μm | Ra <0.2 μm |
| Residual kev ntxhov siab | Tsawg (tsis muaj compression) | Siab (Compressive) |
| Qeeb zog tawg | Ntau zaus | Ho txo qis |
| Txheej Txheem Txheej | Txo | Txuas ntxiv los ntawm 30-50% |
