Nyob rau hauv high-end khoom tsim thiab geometric metrology teb, kub drift thiab ua hauj lwm-surface hnav tau ntev tau ob tug tseem ceeb mob cov ntsiab lus txwv lub sij hawm ntev precision ntawm cov cuab yeej ntsuas. Txawm hais tias ib txwm steel thiab cam khwb cia-hlau ncaj-edges muaj kev paub tab, lawv yuav raug kev txom nyem qhov hloov pauv thiab khawb av nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias thiab nquag ua haujlwm sib txhuam hauv kev cob qhia. Yuav tsum tau kuaj xyuas dua thiab rov ua dua tshiab, ua rau lawv tsis tshua muaj raws li micron- thiab txawm tias sub-micron-theem siv cov kev xav tau hauv kev lag luam xws li semiconductors, optics thiab precision tshuab cuab yeej. Tau txais txiaj ntsig los ntawm cov khoom siv pob zeb tshwj xeeb ntawm pob zeb, granite ncaj-edges sib xyaw ua ke qis-expansion thiab high-wear-tiv taus, thiab tau dhau los ua cov khoom siv tseem ceeb hauv kev ntsuas niaj hnub no.
Qhov qis-expansion kev ua tau zoo ntawm granite ncaj-edges originates los ntawm nruj interwoven micro-structure ntawm ntxhia pob zeb. High-quality precision granite feem ntau yog tsim los ntawm quartz thiab feldspar nrog compact thiab sib npaug sib npaug. Internal residual stress yog tso tawm tag nrho los ntawm ntuj aging tshaj geological cycles. Piv nrog cov hlau thiab cam khwb cia hlau, granite boasts qhov qis dua thermal expansion coefficient. Thaum ambient kub hloov pauv me ntsis, nws qhov kev hloov pauv tag nrho yog txwv rau ib qho me me. Nws zam thermal expansion thiab contraction deformation feem ntau pom nyob rau hauv cov ntaub ntawv hlau, thiab zoo txo qhov tsis ncaj ncees lawm los ntawm qhov kub thiab txias. Ntau qhov chaw tsim khoom tsis tuaj yeem tswj xyuas qhov kub thiab txias. Lub viav vias kub ntawm ob peb degrees tuaj yeem tsim qhov ntsuas ntsuas qhov sib txawv rau cov cuab yeej ntsuas hlau. Ua tsaug rau qhov zoo thermal inertia, granite ncaj-edges tsis ambient kub cuam tshuam thiab khaws cov ntaub ntawv ncaj qha kuj ruaj khov. Lawv txo qhov kev cia siab ntawm qhov kub thiab txias tsis tu ncua thiab hloov mus rau ob qho tib si kuaj ntsuas ntsuas thiab cov txheej txheem kev cob qhia nyuaj. Nws yog ib qho tsim nyog sau cia tias kev nthuav dav qis tsis txhais tau tias muaj kev tiv thaiv tag nrho rau qhov kub thiab txias. Deformation tsuas yog txo qis. Rau ntev-span ncaj-edges, qhov kub-compensation logic tseem yuav tsum tau tshwj tseg kom muab kev ua si tag nrho rau cov khoom siv tau zoo.
High hnav tsis kam lav lub sij hawm ntev geometric daim ntawv ntawm ncaj-ntug siv nto. Granite nce mus txog 6-7 ntawm Mohs hardness nplai, nrog Shore hardness ntau dua li cov hlau cam khwb cia. Nws compact, pore-dawb lithological qauv zoo heev txhim kho khawb-kuj thiab kev sib txhuam-ua haujlwm ntawm qhov chaw ua haujlwm. Hauv kev tshuaj xyuas ua haujlwm, rov ua haujlwm ua haujlwm thiab kev sib txhuam los ntawm cov khib nyiab hlau yog yam tsis muaj kev zam. Kev sib txhuam mus sij hawm ntev yuav tsim cov furrows thiab kev nyuaj siab hauv zos ntawm cov hlau ncaj-edges, ua rau tsis ua hauj lwm sai ntawm qhov chaw siv. Thaum muaj kev sib txhuam tsis tu ncua, granite ncaj-edges tsuas muaj kev puas tsuaj me ntsis ntawm cov pob zeb hauv av es tsis txhob hnav cov nplaum thiab qaug zog spalling. Lawv qhov chaw ua haujlwm lapped tuaj yeem tuav cov ntsuas ncaj nraim rau lub sijhawm ntev, ua kom lub neej ua haujlwm zoo ntawm kev ntsuas cov cuab yeej thiab txo lub Hoobkas rov qab rov ua dua zaus. Tsis tas li ntawd, cov ntaub ntawv pob zeb yuav tsis xeb thiab tiv thaiv kev cuam tshuam los ntawm kev txiav cov kua thiab roj stains. Tsis muaj xeb bulges yuav ua rau cov ntaub ntawv puas tsuaj, ntxiv qhov txo qis qhov poob los ntawm ib puag ncig xov xwm. Txawm li cas los xij, granite yog inherently brittle. Hnav tsis kam tsis sib npaug ntawm kev cuam tshuam. Cov khoom hnyav hnyav tseem yuav ua rau muaj kev cuam tshuam hauv zos, uas yuav tsum tau zam hauv kev siv tswv yim.
Low-expansion and high-wear-resistance tsis yog ib qho qhia tawm. Lawv kev sib koom ua ke coj tawm cov txiaj ntsig zoo ntawm granite ncaj-edges. Tsawg expansion daws precision drift tshwm sim los ntawm ib puag ncig kev hloov pauv, thaum hnav tsis kam tiv thaiv kev puas tsuaj tom qab kev pabcuam ntev. Lawv qhov sib xyaw ua ke paub txog lub sijhawm ruaj khov thiab ib puag ncig hloov pauv ntawm cov neeg siv khoom siv. Hauv cov xwm txheej suav nrog cov cuab yeej qhia kev ntsuas lub tshuab, kev sib dhos cov khoom siv kho qhov muag, kev tshuaj xyuas cov khoom siv semiconductor thiab kuaj pwm loj, granite ncaj-edges xa cov ntaub ntawv ncaj qha ncaj qha, txiav cov txheej txheem tsis raug los ntawm qhov kub thiab txias, pab cov tuam txhab txo cov nqi ntsuas-cov cuab yeej tu thiab txhim kho cov ntaub ntawv sib xws hauv kev tshuaj xyuas batch.
Los ntawm qhov kev xav ntawm kev tsim kho kev lag luam, domestic super-precision granite tivthaiv thev naus laus zis tau hloov kho dua tshiab. Los ntawm kev soj ntsuam cov pob zeb nyoos, cov khoom siv hluav taws xob theem nrab thiab cov txheej txheem ntau dhau super-precision lapping txheej txheem, cov khoom siv tau zoo dua qub ntxiv. Cov khoom tau raug xa mus rau cov koom haum tshawb fawb thiab thoob ntiaj teb cov tuam txhab high-end. Cov kev coj ua hauv kev lag luam qhia tias cov khoom siv ib leeg tsis tuaj yeem txiav txim siab ua tiav cov khoom tiav; raw-khoom siv tshuaj ntsuam xyuas, cov txheej txheem kev ntxhov siab-nyem thiab cov qauv lapping tseem ceeb sib npaug. Nrog kev txhim kho txuas ntxiv ntawm kev tsim khoom hauv tsev high-end, xav tau cov cuab yeej siv ruaj khov nce ntxiv. Featuring low-expansion and high-wear-resistance, granite ncaj-edges yuav ntxiv thiab maj mam hloov cov khoom siv hlau ntsuas hauv cov xwm txheej super-precision ntau dua thiab nteg lub hauv paus metrological rau precision manufacturing.
