Ua ntej peb mus rau hauv daim ntawv qhia saum npoo, cia peb nkag siab tias qhov chaw ua tiav dab tsi entails.
Surface finish yog hais txog cov txheej txheem ntawm kev hloov cov hlau qhov chaw uas yuav tsum tau tshem tawm, ntxiv, los yog reshaping. Nws yog ib qho kev ntsuas ntawm qhov ua tiav kev ntxhib los mos ntawm cov khoom nto uas txhais los ntawm peb yam ntxwv ntawm qhov roughness, waviness thiab nteg.
Qhov saum npoo roughness yog qhov ntsuas ntawm tag nrho qhov sib txawv ntawm qhov tsis sib xws ntawm qhov chaw. Thaum twg cov kws kho tshuab tham txog "nto tiav," lawv feem ntau hais txog qhov roughness.
Waviness yog hais txog qhov chaw warped uas nws qhov sib nrug ntau dua li qhov ntev ntawm qhov roughness. Thiab nteg yog hais txog cov kev taw qhia uas tus qauv nto moo tshaj yuav siv. Machinists feem ntau txiav txim siab qhov nteg los ntawm txoj kev siv rau saum npoo.
3.2 nto tiav txhais li cas
A 32 nto tiav, tseem hu ua 32 RMS tiav lossis 32 microinch tiav, hais txog qhov roughness ntawm cov khoom lossis cov khoom. Nws yog ib qho kev ntsuas ntawm qhov nruab nrab qhov siab variations los yog deviations nyob rau hauv qhov kev ntxhib los mos nto. Nyob rau hauv cov ntaub ntawv ntawm 32 nto tiav, qhov siab variations yog feem ntau nyob ib ncig ntawm 32 microinches (los yog 0.8 micrometers). Nws qhia tau hais tias ib tug kuj du nto nrog zoo zoo nkauj thiab tsawg imperfections. Tus lej qis dua, qhov zoo dua thiab smoother ntawm qhov chaw tiav.
Dab tsi yog RA 0.2 nto tiav
RA 0.2 nto tiav yog hais txog ib qho kev ntsuas ntawm qhov roughness. "RA" stands rau Roughness Nruab Nrab, uas yog ib qho parameter siv los ntsuas qhov roughness ntawm qhov chaw. Tus nqi "0.2" sawv cev rau qhov nruab nrab roughness hauv micrometers (µm). Hauv lwm lo lus, qhov chaw tiav nrog tus nqi RA ntawm 0.2 µm qhia tau hais tias qhov zoo nkauj heev thiab zoo nkauj. Hom kev ua tiav saum npoo no feem ntau ua tiav los ntawm kev ua haujlwm precision lossis polishing txheej txheem.
ZhongRui TubeElectropolished (EP) Seamless Tube
Electropolished Stainless Hlau Tubingyog siv rau biotechnology, semiconductor thiab hauv kev siv tshuaj. Peb muaj peb tus kheej polishing cov cuab yeej thiab tsim electrolytic polishing raj uas ua tau raws li qhov yuav tsum tau muaj ntawm ntau lub teb raws li kev taw qhia ntawm pab pawg neeg Kauslim.
