Granite bases, muaj nuj nqis rau lawv cov rigidity siab, tsis tshua muaj thermal expansion, thiab zoo heev tiv thaiv corrosion, yog dav siv nyob rau hauv precision instruments, kho qhov muag systems, thiab industrial metrology daim ntaub ntawv. Lawv qhov tseeb qhov tseeb ncaj qha cuam tshuam rau kev sib sau ua ke, thaum kev tu thiab tu kom zoo txiav txim siab txog kev ruaj ntseg ntev thiab ntsuas qhov tseeb. Hauv qab no, peb piav qhia txog cov ntsiab lus ntawm qhov ntsuas qhov ntev thiab cov kev coj ua zoo tshaj plaws rau kev tu thiab tu.
1. Dimensional Definition – Function-Oriented Precision Design
1.1 Tsim Cov Qauv Txheej Txheem
Qhov tsis zoo ntawm granite puag-ntev, dav, thiab qhov siab-yuav tsum tau txiav txim siab raws li cov khoom siv tag nrho. Tus qauv tsim yuav tsum ua qhov tseem ceeb rau kev ua haujlwm thiab kev sib raug zoo ntawm spatial:
-
Rau cov cuab yeej kho qhov muag, kev tshem tawm ntxiv yuav tsum raug tso cai kom tsis txhob cuam tshuam.
-
Rau high-precision ntsuas hauv paus, qis qhov siab pab txo qis kev sib kis thiab txhim kho kev ruaj ntseg.
ZHHIMG® ua raws li lub hauv paus ntsiab lus ntawm "kev ua haujlwm ua ntej, cov qauv kev cog lus", ua kom cov nqi ua haujlwm tsis muaj kev cuam tshuam.
1.2 Txhais qhov tseem ceeb ntawm cov qauv qhov ntev
-
Mounting Surface: Qhov chaw tiv tauj yuav tsum npog tag nrho cov cuab yeej txhawb nqa, tsis txhob muaj kev ntxhov siab hauv cheeb tsam. Rectangular li xav tau me ntsis qhov loj me me rau kev hloov kho, thaum cov khoom siv ncig tau txais txiaj ntsig los ntawm concentric mounting nto los yog nrhiav tus thawj coj.
-
Positioning Holes: Threaded thiab nrhiav qhov yuav tsum phim cov khoom siv txuas. Ib qho symmetrical faib ua kom muaj zog torsional rigidity, thaum hloov qhov tso cai rau kev calibration zoo.
-
Luj-Txo Grooves: Tsim nyob rau hauv cov cheeb tsam uas tsis yog-load-bearing kom txo cov huab hwm coj thiab cov nqi khoom. Cov duab (cov duab plaub, voj voog, lossis trapezoidal) yog qhov ua tau zoo raws li kev soj ntsuam kev ntxhov siab los khaws cov rigidity.
1.3 Tolerance Control Philosophy
Dimensional tolerances qhia txog qhov machining precision ntawm granite puag:
-
High-precision daim ntaub ntawv (xws li, semiconductor manufacturing) thov flatness tswj mus rau qib micron.
-
Kev siv dav dav tso cai rau me ntsis looser kam rau ua.
ZHHIMG® siv lub hauv paus ntsiab lus ntawm "kev nruj me ntsis ntawm qhov tseem ceeb, hloov tau ntawm qhov tsis tseem ceeb", ntsuas qhov tseeb nrog cov nqi tsim khoom los ntawm cov txheej txheem kev ua haujlwm siab thiab ntsuas.
2. Kev tu thiab tu - Ua kom muaj kev ntseeg siab ntev
2.1 Kev xyaum tu txhua hnub
-
Kev tshem tawm plua plav: Siv txhuam txhuam los yog lub tshuab nqus tsev kom tshem tawm cov khoom thiab tiv thaiv khawb. Rau cov stains tawv, ib daim ntaub tsis muaj lint-dawb dampened nrog dej distilled yog pom zoo. Tsis txhob corrosive cleaning agents.
-
Roj thiab Coolant Tshem Tawm: Tam sim ntawd so qhov chaw paug nrog isopropyl cawv thiab qhuav lawm. Roj residues tuaj yeem txhaws qhov pores thiab cuam tshuam rau cov dej noo.
-
Kev Tiv Thaiv Hlau: Siv ib txheej nyias ntawm cov roj los tiv thaiv xeb rau threaded thiab nrhiav qhov los tiv thaiv corrosion thiab tswj kev sib dhos.
2.2 Advanced Cleaning rau Complex Contamination
-
Tshuaj lom neeg: Nyob rau hauv cov ntaub ntawv ntawm acid / alkali sib cuag, ntxuav nrog ib tug nruab nrab buffer tov, yaug kom huv si nrog distilled dej, thiab cia 24 teev kom tiav ziab.
-
Kev Loj Hlob: Yog tias pwm lossis algae tshwm nyob rau hauv qhov chaw ntub dej, tshuaj tsuag nrog 75% cawv, txhuam maj mam, thiab siv UV sterilization. Cov tshuaj chlorine-raws li yog txwv tsis pub kom tsis txhob muaj xim.
-
Kev Kho Cov Qauv: Micro-cracks lossis ntug chipping yuav tsum tau kho nrog epoxy resin, ua raws li kev sib tsoo thiab rov polishing. Tom qab kho, qhov tseeb qhov tseeb yuav tsum tau rov qab xyuas dua.
2.3 Tswj Kev Tu Ib puag ncig
-
Khaws qhov kub thiab txias (20 ± 5 ° C) thiab av noo (40-60% RH) thaum ntxuav kom tsis txhob nthuav lossis contraction.
-
Hloov cov cuab yeej ntxuav (dawb, txhuam) tsis tu ncua kom tsis txhob muaj kab mob sib kis.
-
Tag nrho cov haujlwm saib xyuas yuav tsum tau sau tseg rau tag nrho lub neej traceability.
3. Cov lus xaus
Qhov tseeb qhov tseeb thiab kev tu xyuas ntawm lub hauv paus granite yog qhov tseem ceeb rau nws qhov kev ua tau zoo thiab kev ua neej nyob. Los ntawm kev ua raws li cov qauv tsim qauv tsim, ua kom zoo rau kev sib koom ua ke, thiab cov txheej txheem tu kom zoo, cov neeg siv tuaj yeem ua kom ruaj khov mus ntev, kev ntseeg siab, thiab ntsuas qhov tseeb.
Ntawm ZHONGHUI Group (ZHHIMG®), peb muab cov khoom siv hauv ntiaj teb-chav granite, ISO-certified ntau lawm, thiab ntau xyoo ntawm craftsmanship kom xa granite hauv paus uas ua tau raws li cov qauv xav tau tshaj plaws hauv semiconductor, metrology, thiab precision engineering industries.
