Los ntawm Daim Qauv Mus Rau Qhov Tseeb: Cov Txheej Txheem Tsim Khoom ntawm Cov Cheebtsam Granite Tshwj Xeeb

Hauv lub ntiaj teb ntawm kev tsim kho tshuab siab, qhov twg qhov ntsuas qhov yuam kev hauv microns, granite tsis yog pob zeb xwb - nws yog lub hauv paus ntawm qhov tseeb. Txij li cov hauv paus ntawm Coordinate Measuring Machines (CMM) mus rau cov theem ntawm semiconductor lithography systems, cov khoom granite ua raws li kev cai ua lub luag haujlwm tseem ceeb hauv kev ua kom ruaj khov, kev co damping, thiab kev tiv thaiv thermal.

Chiv Keeb: Kev Xaiv Khoom Siv thiab Kev Ruaj Ntseg Geological

• Cov Qauv Nplej: Lub pob zeb yuav tsum muaj cov noob nplej zoo thiab sib xws. Cov siv lead ua loj lossis cov kab nrib pleb loj tuaj yeem ua rau muaj qhov tawg me me thaum lub sijhawm ua haujlwm lossis hnav tsis sib xws raws sijhawm.
• Kev Laus Ntuj: Thaum khawb av, cov chaw tsim khoom zoo tshaj plaws cia cov pob zeb nyoos "so" lossis laus ntuj rau ntau lub hlis. Qhov kev raug rau cov ntsiab lus no pab tso tawm cov kev ntxhov siab geological uas raug kaw hauv pob zeb. Yog tias hla cov kauj ruam no, kev ntxhov siab sab hauv yuav ua rau cov khoom tiav lawm warp lossis twist, ua rau nws puas tsuaj.

Theem 1: Kev Siv Tshuab Rough Machining - Shaping the Beast

• Kev Txiav Hlau Pob Zeb Diamond: Txhawm rau txiav cov pob zeb loj no, cov chaw tsim khoom siv cov hlau pob zeb diamond hauv kev lag luam. Tsis zoo li cov hniav ib txwm muaj, cov hlau uas muaj pob zeb diamond ua rau muaj kev txiav cov pob zeb tawv kom raug nrog kev pov tseg tsawg kawg nkaus.
• CNC Milling: Rau cov khoom uas muaj cov qauv geometries nyuaj—xws li T-slots, threaded inserts, lossis cov qhov mounting tshwj xeeb—Computer Numerical Control (CNC) milling tshuab nruab nrog cov cuab yeej diamond-tolerant siv. Nyob rau theem no, qhov kev tsom mus rau kev tshem tawm cov khoom loj kom ze rau qhov loj me, feem ntau tawm ntawm 1-2 hli rau cov txheej txheem tiav.

Theem 2: Kev Tshawb Fawb Txog Kev Txo Kev Nyuaj Siab

• Cov Txheej Txheem: Cov blocks uas tau ua tiav lawm raug muab tso rau hauv cov qhov cub loj, uas tswj hwm los ntawm lub khoos phis tawj. Lawv raug cua sov rau qhov kub tshwj xeeb (feem ntau ntawm 450 ° C thiab 600 ° C) thiab tom qab ntawd txias qeeb qeeb rau ob peb hnub raws li qhov nkhaus meej.
• Qhov Tshwm Sim: Qhov kev hloov pauv kub no ua raws li xyoo ntawm kev laus ntawm ntuj tsim hauv ob peb hnub xwb. Nws ua rau cov qauv siv lead ua sab hauv ntawm lub pob zeb so, ua kom ntseeg tau tias thaum nws ua tiav, nws yuav nyob ruaj khov rau ntau xyoo caum.

Theem 3: Kev Sib Tsoo Kom Tseeb - Kev Nrhiav Kom Tiaj

• Kev Sib Tsoo Nto: Cov tshuab sib tsoo nto loj siv los ua kom cov nto sab saud thiab sab hauv qab tiaj. Cov txheej txheem no tshem tawm cov "cim pom" ntawm qhov txiav thawj zaug thiab tsim kom muaj qhov sib luag thawj zaug.
• Kev Tswj Xyuas Cov Dej Txias: Kev sib tsoo granite tsim cov cua sov thiab cov hmoov silica ntau heev. Txhawm rau tiv thaiv qhov no, cov chaw tsim khoom siv cov dej txias ntau heev. Qhov no tsis yog tsuas yog tiv thaiv cov hmoov av (qhov yuav tsum tau muaj kev nyab xeeb tseem ceeb) tab sis kuj tiv thaiv lub pob zeb kom tsis txhob nthuav dav vim muaj cua sov, uas yuav cuam tshuam rau qhov tseeb ntawm kev sib tsoo.

Theem 4: Kev Khawb Tes thiab Kev Lapping - Kev Kos Duab ntawm Kev Zoo Tag Nrho

• Kev Khawb Tes: Cov kws txawj siv cov khawb tes los khawb cov pob zeb me me. Los ntawm kev siv lub phaj siv lossis lub laser interferometer ua tus qhia, tus neeg ua haujlwm txheeb xyuas cov chaw siab (feem ntau qhia los ntawm Prussian Blue dye) thiab khawb lawv. Qhov no tsim cov qauv "frosted" lossis checkered uas feem ntau pom ntawm cov phaj nto siab. Cov qauv no tsis yog tsuas yog zoo nkauj xwb; cov hnab tshos pab khaws cov roj, txo kev sib txhuam rau cov khoom swb.
• Kev Sib Txhuam: Rau qhov ua tiav du heev (yuav tsum muaj rau cov kabmob cua lossis cov khoom siv kho qhov muag), qhov chaw yuav raug sib txhuam. Cov hmoov txhuam (feem ntau yog Silicon Carbide lossis Diamond) raug nthuav tawm rau saum npoo, thiab lub cuab yeej sib txhuam raug txav mus rau saum nws kom txhuam lub pob zeb kom zoo li daim iav tiav. Cov txheej txheem no tuaj yeem ua tiav qhov roughness ntawm qhov chaw (Ra) tsawg dua 0.1 microns.

Theem 5: Kev Sib Dhos thiab Kev Sib Txuas

• Kev Sib Txuas: Vim tias granite tsis yooj yim vuam lossis kov zoo li hlau, cov ntxig feem ntau raug sib txuas siv cov epoxy muaj zog heev. Tus neeg tsim khoom yuav tsum tho qhov, ntxuav nws nrog tshuaj lom neeg kom tshem tawm tag nrho cov hmoov av, thiab txhaj cov nplaum.
• Kev Xauv Tshuab: Hauv qee qhov kev siv khoom hnyav, cov hlau ntxig tau raug kho lossis dovetailed rau hauv pob zeb kom tiv thaiv rub tawm.
• Kev Kho: Lub rooj sib txoos raug tso tseg kom kho rau ib lub sijhawm tshwj xeeb kom ntseeg tau tias qhov kev sib txuas muaj zog npaum li lub pob zeb nws tus kheej.

Theem 6: Kev Ntsuam Xyuas Zoo - Qhov Kev Txiav Txim Zaum Kawg

• Kev Tiaj thiab Kev Sib Npaug: Cov khoom no raug ntsuas siv Lub Tshuab Hluav Taws Xob Qib lossis Laser Interferometer. Lub teeb laser raug tua hla qhov chaw, thiab lub khoos phis tawj tsim daim ntawv qhia topographical, qhia cov ncov thiab cov hav hauv microns.
• Kev Ntsuas Rockwell Hardness: Tej qhov chaw random ntawm cov khoom yuav raug kuaj xyuas kom paub tseeb tias cov granite ua tau raws li qhov yuav tsum tau ua kom tawv (feem ntau yog Mohs 6-7).
• Kev Tshuaj Xyuas Pom: Qhov chaw raug tshuaj xyuas hauv qab lub teeb ci ntsa iab rau txhua qhov khawb, qhov tawg, lossis cov qauv "txiv kab ntxwv tev" uas qhia txog kev txhuam tsis zoo.

Kev Ntim Khoom thiab Kev Xa Khoom: Qhov Kawg

• Kev Ntim: Cov khoom tau ntim rau hauv cov ntoo plywood uas tsis muaj fumigation.
• Kev Cais Tawm: Cov granite yeej tsis kov cov ntoo ncaj qha. Nws raug dai rau ntawm cov ua npuas dej siab lossis cov roj hmab kom nqus tau kev co thaum thauj khoom hauv dej hiav txwv.
• Kev Tiv Thaiv Dej Nqus: Vim tias granite yog qhov ntxeem tau, nws yog qhwv rau hauv VCI (Volatile Corrosion Inhibitor) daim ntawv lossis cov yas hnyav nrog cov desiccants los tiv thaiv kev nqus dej noo thaum lub sijhawm thauj mus los hauv hiav txwv.
