Nyob rau hauv ultra-precision manufacturing teb xws li kev soj ntsuam semiconductor, kho qhov muag khoom siv thiab siab -precision motion platforms, qhov kawg machining raug, nto zoo thiab ntev -lub sij hawm stability ntawm dub granite siv cov khoom nyob ntawm tsis tsuas yog nyob rau hauv cov khoom sib tsoo thiab kev tsim cov txheej txheem, tab sis kuj nyob rau hauv lub hauv paus chiv keeb ntawm cov pob zeb. Dub granite nrog zoo sib xws ntawm kev ua lag luam muab kev sib txawv machining kev ua tau zoo. Qee tus tuaj yeem ncav cuag qhov muag pom tau yooj yim ultra- cov qauv tiaj tus, thaum lwm tus tuaj yeem ua rau pits, waviness, grain shedding thiab raug drift. Qhov laj thawj tseem ceeb nyob rau hauv qhov sib txawv ntawm cov ntxhia hauv cov khoom, cov nplej morphology, impurity ratio thiab pore qauv. Kos rau ntev - lub sij hawm raw khoom xaiv thiab ultra- precision machining kev, UNPARALLELED systematically soj ntsuam seb cov ntxhia muaj pes tsawg leeg ntawm dub granite cuam tshuam rau nws ultra- precision machinability.
1. Mineral Proportion Structure: Txiav txim siab lub Upper Limit of Flatness hauv Finish Machining
Dub granite nplooj siab rau siab -kawg precision machining mas muaj quartz, feldspar, maub minerals thiab trace filler crystals. Minerals sib txawv heev nyob rau hauv hardness, toughness thiab sib tsoo zog, uas ncaj qha mus rau lub tiav machining tau. Quartz nta siab hardness thiab ruaj khov qauv, ua tus tseem ceeb tivthaiv kom lav lub rigidity thiab seem stability ntawm lub pob zeb. Feldspar ua lub hauv paus ntsiab lus ntawm granite thiab ua kom muaj kev sib koom ua ke ntawm cov qauv. Cov pob zeb tsaus nti ua kom lub zog compactness thiab vibration damping muaj peev xwm.
Yog hais tias flaky mica thiab cov ntxhia mos yog concentrated nyob rau hauv lub pob zeb, lub zos tev thiab pitting tsis xws luag yuav yooj yim tshwm sim thaum lub sij hawm ultra-precision lapping, ua rau nws tsis yooj yim sua kom tau optical- qib nto nrog ultra- tsawg roughness. UNPARALLELED proprietary dub granite undergoes nruj raw khoom soj ntsuam nrog sib npaug ntxhia proportions thiab tusyees dispersed mos impurities yam tsis muaj enrichment hauv zos. Nws ua tiav cov txheej txheem tshem tawm thiab ua kom zoo sib xws thaum sib tsoo, ruaj khov xa cov nano- theem saum npoo tiav haum rau siab - qhov tseeb qhov xwm txheej suav nrog AOI kho qhov muag tshuaj xyuas thiab wafer metrology.
2. Grain Size thiab Crystallization State: Kev cuam tshuam ntawm Nto Waviness thiab Micro Machining Defects
Grain loj yog ib qho tseem ceeb qhia qhov txawv ntawm cov pob zeb zoo tib yam los ntawm precision-qib granite. Coarse-grained granite nta cov khoom siv lead ua loj loj thiab pom tseeb lis ciam ciam. Cov qoob loo zoo li poob raws li cov ciam teb thaum lub sij hawm milling, grooving thiab ultra- precision lapping, tsim cov micro textures tsis zoo thiab tsis sib xws nrog cov waviness tsis zoo, ua tsis tau raws li qhov yuav tsum tau ua ntawm cov huab cua bearing platforms thiab siab - cov khoom siv txhais lus. Lub caij no, ntxhib- pob zeb ua pob zeb ua rau muaj kev puas tsuaj ntau dua tom qab kev ua haujlwm, uas tuaj yeem ua rau me ntsis qhov dav dav hauv lub sijhawm ntev.
Premium ultra-precision dub granite txais yuav zoo-cov khoom siv lead ua zoo sib xws nrog cov txheej txheem zoo sib xws thiab sib cuam tshuam. Kev tshem tawm cov khoom ua haujlwm tsis tu ncua thiab tswj tau hauv kev sib tsoo yam tsis muaj qoob loo, ntug chipping lossis hauv zos tawg. Xws li cov yam ntxwv zoo crystallization tshem tawm machining textures mus rau qhov siab tshaj plaws thiab ua kom zoo dua qhov waviness. Lub dav hlau siv granite ua tau zoo dua qhov flatness thiab micro flatness, nteg lub hauv paus tseem ceeb rau ntev -lub sij hawm ruaj khov precision.
3. Pore thiab impurity Distribution: cuam tshuam rau Machining Yield thiab Cleanroom Compatibility
Micropores, microcracks thiab ntxhia impurities nyob rau hauv ntuj pob zeb yog zais kev phom sij rau ultra- precision machining. Pa dub granite muaj interconnected thiab xoob micropores. Abrasive plua plav yog yuav embed rau hauv pores thaum lapping, tsis tu ncua khawb qhov siv nto thiab ua rau tsis txaus siab roughness thiab tsis sib xws ntawm qhov chaw. Tsis tas li ntawd, qhov pores nyiam cov khoom khib nyiab, uas tsis tuaj yeem ua raws li cov qauv ntawm cov plua plav-cov kev cob qhia pub dawb thiab cov kab hluav taws xob semiconductor huv.
Qee qhov tsis zoo blasts muaj pyrite thiab xoob filling impurities. Tsis muaj kev sib raug zoo ntawm cov impurities thiab cov pob zeb matrix ua rau yooj yim detachment thaum lub sij hawm tiav machining, drilling thiab grooving, tsim cov pits mus tas li uas khawb siab -cov khoom muaj tseeb. UNPARALLELED conducts comprehensive inspections before raw materials are put into production, eliminating blasts with dense pores, enriched impurities and microcracks. Peb xaiv high-density, low-porosity raw cov ntaub ntawv kom tsis txhob machining defects los ntawm qhov chaw. Cov khoom tiav yog compact, du, tsis muaj embedded hmoov thiab particle shedding, ua tau raws li qhov huv thiab siab -kev ua haujlwm zoo ntawm ultra- khoom siv precision.
4. Inherent Mineral Properties: Correlating Thermal Stability thiab Vibration Damping Adaptability
Mineral muaj pes tsawg leeg tsis tsuas cuam tshuam qhov zoo tom qab machining, tab sis kuj txiav txim siab lub cev lub zog ntawm cov pob zeb tiav, tsis ncaj qha cuam tshuam rau tag nrho cov khoom raug. Dub granite nrog cov ntsiab lus quartz txaus muaj cov thermal expansion coefficient tsawg. Nws qhov sib txawv ntawm qhov sib txawv tshwm sim los ntawm qhov kub thiab txias tom qab machining yog tsawg, tuav ntev - lub sij hawm seem stability ntawm precision qhov, siv dav hlau thiab cua bearing grooves.
Tsis tas li ntawd, staggered siv lead ua cuam tshuam zoo nqus kev vibration zog thiab endow granite nrog zoo damping kev ua tau zoo. Piv nrog rau cov pob zeb zoo tib yam uas muaj cov ntxhia pob zeb muaj pes tsawg leeg thiab cov qauv nruj, granite nrog cov ntxhia sib npaug sib luag muab kev muaj zog resonance suppression tom qab machining. Nws yoog mus rau siab - zaus ua haujlwm ntawm qhov siab - nrawm linear motor platforms thiab dynamic optical scanning khoom, tiv thaiv qhov raug yuam kev tshwm sim los ntawm cov khoom siv dynamic vibration.
5. Cov txheej txheem ntxhia sib txawv uas yuav tsum tau ua kom zoo dua thiab kho cov txheej txheem machining
Granite nrog ntau cov qauv ntxhia muaj qhov sib txawv ntawm kev ua haujlwm siab, thiab cov txheej txheem thoob ntiaj teb tsis tuaj yeem haum txhua hom pob zeb. Siab-quartz nyuaj pob zeb ua rau hnyav hnyav ntawm kev sib tsoo log, yog li txiav ceev thiab pub tus nqi yuav tsum tau ua kom zoo dua kom tsis txhob muaj kev puas tsuaj los ntawm kev sib txhuam ntawm cov cua sov. Rau pob zeb nrog cov ntsiab lus siab mica, lapping siab yuav tsum tau txo thiab machining ceev qeeb kom tiv thaiv tev ntawm flaky minerals.
Raws li cov ntxhia cov yam ntxwv ntawm cov tswv dub granite, UNPARALLELED tsim cov txheej txheem tshwj xeeb cov ntaub ntawv. Kev txhawb nqa los ntawm Chav Kawm 10,000 qhov kub thiab txias qhov chaw huv si, peb tsim cov txheej txheem ua tiav nrog rau kev sib tw gradient, qis- ua kom tiav thiab txo kev ntxhov siab. Machining schemes yog matched raws li grain loj, hardness thiab pore yam ntxwv ntawm pob zeb kom tsis txhob muaj ntau yam machining defects thiab ua kom muaj kev ua tau zoo tshaj plaws ntawm cov khoom siv ntxhia zoo. Tag nrho cov khoom tiav tiav ncav cuag cov qauv ntsuas thoob ntiaj teb hauv kev tiaj tus, roughness thiab seem stability.
