Nyob rau hauv precision manufacturing thiab metrology laboratories, lub granite nto phaj ua hauj lwm raws li lub hauv paus siv dav hlau rau kev soj ntsuam qhov ntev. Txawm hais tias siv rau kev teeb tsa ua haujlwm, ntsuas qhov ntsuas ntsuas qhov tseeb, lossis ua lub hauv paus rau cov cuab yeej ntsuas ntsuas ntsuas, qhov tseeb ntawm granite nto phaj ncaj qha cuam tshuam kev ntsuas kev ntseeg tau thiab cov khoom zoo.
Txawm li cas los xij, txawm tias qhov siab tshaj - Qib Qib 000 granite daim hlau tsis tiv thaiv kev hnav thiab ib puag ncig kev puas tsuaj. Sij hawm dhau mus, rov qab sib cuag nrog cov cuab yeej ntsuas, cov khoom ua haujlwm, thiab cov khoom siv sib txuas tuaj yeem tsim cov khoom siv microscopic uas cuam tshuam qhov flatness. Cov lus qhia dav dav no muab cov kws tshaj lij- cov txheej txheem qib rau Granite Surface Plate Calibration thiab Maintenance Guide kom paub meej ntev -Lub sij hawm Surface Plate Accuracy.
Nkag siab Qib 000 Cov Lus Qhia Tshwj Xeeb
Qib 000 sawv cev rau lub pinnacle ntawm granite nto phaj precision, tsim los rau cov kev thov kev ntsuas feem ntau suav nrog kev tsim khoom semiconductor, kho qhov muag calibration, thiab aerospace tshuaj xyuas. Raws li cov txheej txheem thoob ntiaj teb (ASME B89.3.7 thiab qhov sib npaug sib npaug), Qib 000 daim hlau yuav tsum muaj qhov tshwj xeeb nruj flatness kam rau ua:
表格
| Phaj Loj (mm) | Qib 000 Flatness kam rau ua (μm) |
|---|---|
| 300×200 | 0.9 |
| 400×250 | 1.0 |
| 630×400 | 1.3 |
| 1000×630 | 1.5 |
| 1000×1000 | 1.8 |
| 1600×1000 | 2.0 |
Lub flatness kam rau ua raws li cov qauv: kam rau ua=Qib Coefficient × (1 + d/1000) μm, qhov twg d sawv cev rau kab pheeb ces kaum ntev hauv millimeters. Rau Qib 000, tus coefficient sib npaug 1, nrog rau kev ntsuas ntsuas ntawm tus qauv ntsuas kub (20 ± 2 degree).
Qhov tseem ceeb tseem ceeb ntawm kev ntsuas tsis tu ncua
Thaum granite muaj qhov tshwj xeeb qhov ruaj khov thiab hnav tsis kam piv rau cov kev xaiv hlau cam khwb cia, kev txheeb xyuas lub sijhawm tseem tseem ceeb rau kev tswj xyuas qhov tseeb. Txawm tias qhov sib txawv me me tuaj yeem cuam tshuam rau hauv kev ntsuas qhov yuam kev hauv siab - cov ntawv thov raug.
Kev ntsuas txhua xyoo yog qhov tseem ceeb rau ntau yam laj thawj:
Kev Nyab Xeeb Kev Ua Tau Zoo: Ua raws li cov qauv hauv tebchaws thiab thoob ntiaj teb, qhov tseem ceeb rau ISO 9001, ISO 17025, thiab aerospace kev xav tau zoo
