Loj-loj granite hauv paus yog dav siv nyob rau hauv ntev-txoj kev air-bearing platforms, loj-qhov chaw kho qhov muag khoom soj ntsuam thiab loj-scale metrology ntsuas. Raws li workpiece qhov ntev nce, micro-deformations tshwm sim los ntawm tus kheej qhov hnyav, clamping kev nyuaj siab, machining tshav kub thiab cov khoom aging defects multiply. Cov ntaub ntawv soj ntsuam hauv zos tuaj yeem pom cov txiaj ntsig tau, tab sis tag nrho cov khoom ua haujlwm raug kev txom nyem micron-theem warpage thiab distortion, uas ua rau degraded cov lus qhia-rail ncaj nraim thiab tsis sib haum xeeb hla qhov tseeb tom qab sib dhos. Xws li latent micro-deformations yog ib qho nyuaj rau kev ntes ntawm cov pa ib leeg-point xeem thiab ua ib qho kev sib tw loj rau kev tsim cov khoom loj granite. Kev kos duab ntawm kev ua tau zoo nrog ntau yam 1-6-meter granite hauv paus tej yaam num, UNPARALLELED Group elaborates micro-deformation tswj cov tswv yim uas yuav tsum tau npog cov dawb paug pre-kho, clamping tooling, machining schemes, thermal-ib puag ncig tswj thiab tshuaj xyuas nyiaj.
1. Kev Kho Mob Ua Ntej Tsis Muaj Peev Xwm: Tshem tawm cov kev ntxhov siab uas nyob hauv qhov khoob loj
Loj granite blanks ua rau muaj kev ntxhov siab sab hauv thaum quarrying, txiav thiab ntxhib sawing. Cov ntim loj dua ua rau muaj kev ntxhov siab ntau dua. Yog xa ncaj qha mus ua kom tiav machining, kev ntxhov siab tso tawm tom qab tshem tawm cov khoom ua rau micron-scale warpage.
Kev laus lub sij hawm luv luv tsis tuaj yeem txo qhov kev ntxhov siab hauv qhov khoob loj. UNPARALLELED siv cov khoom siv ntau-kauj ruam tshem tawm ntxiv nrog rau cov txheej txheem kev laus mus ntev. Tom qab kev ua haujlwm ntxhib tshem tawm cov khoom lag luam feem ntau, cov khoob khoob raug xa mus rau qhov chaw ua haujlwm kub thiab txias rau lub sijhawm ntev static cia nrog cyclic thermal cuam tshuam kom tso tawm sab hauv kev ntxhov siab txaus. Semi-fine sib tsoo pib tsuas yog tom qab qhov loj me stabilize. Kev soj ntsuam nruj nruj txwv tsis pub cov khoom siv tsis sib xws lossis cov txheej txheem hloov maj mam kom txo tau qhov kev pheej hmoo deformation los ntawm qhov chaw. Ua kom tiav daim ntawv qhia txog lub cev-kheej yog muab rau txhua pawg.
2. Cov cuab yeej txhawb nqa yooj yim: Tsis txhob yuam kev deformation los ntawm Rigid Clamping
Ntau lub tuam txhab tseem siv nruj-phaj nyuaj clamping rau cov hauv paus loj granite. Ntau lub zog hauv zos los ntawm nruj clamps tsim compressive deformation ntawm brittle rigid granite. Thaum cov khoom raug tso tawm, kev ntxhov siab rov ua rau cov khoom ua haujlwm tsis zoo thiab rhuav tshem qhov tseeb ntawm qhov tseeb.
Rau qhov loj-loj workpieces, hnyav ib-taw tes clamping yog tso tseg nyob rau hauv kev txaus siab ntawm kev faib hloov pauv-txhawb cov cuab yeej. Ntau qhov sib npaug-spaced kev txhawb nqa tuav hauv qab saum npoo kom tawg nws tus kheej qhov hnyav thiab tiv thaiv kev ncua ib nrab. Lateral txwv blocks tsuas yog siv rau qhov chaw tsis muaj lub zog clamping kom txo qis sab nraud clamping-induced stress. Tus kheej qhov hnyav deflection yog ntsuas ntawm cov cuab yeej tsim theem kom tsis txhob muaj qhov micro-deformation tshwm sim los ntawm qhov nruab nrab ntawm qhov chaw raug ncua.
3. Kev tshem tawm cov txheej txheem txheej: Tiv thaiv kom tsis txhob deformation tshwm sim los ntawm kev hloov pauv ntawm kev ntxhov siab
Kev sib tsoo ntau dhau ntawm ib qho kev sib tsoo qhov tob ua rau qhov kev nyuaj siab ntawm lub tshuab ua haujlwm thiab cov khoom sib tsoo sib tsoo, ua rau hauv zos expansion-contraction thiab post-machining rebound distortion.
Kev ua kom zoo txheej txheej-sib tsoo yog siv: kev sib tsoo ntxhib tshem tawm cov khoom lag luam, kev sib tsoo semi-zoo txo qhov tob, thiab kev sib tsoo ua tiav ntxiv txo cov khoom tshem tawm kom tso tawm cov txheej txheem kev ntxhov siab step-by-step. Alternate machining rau pem hauv ntej thiab nram qab lub ntsej muag kom tsis txhob muaj kev ntxhov siab tsis txaus siab los ntawm ib sab ntawm cov khoom tshem tawm thiab tiv thaiv ib sab dabtsi yog khoov. Qhov, counter-sinks thiab embedded-sleeve nta tau ua tiav ua ntej tag nrho cov kev sib tsoo kom tshem tawm cov deformation cuam tshuam los ntawm kev tshem tawm hauv zos tom ntej.
4. Ib puag ncig-Temperature Machining Ib puag ncig: Tshem Tawm Thermal-Induced Micro-Deformation
Txawm tias tsis tshua muaj thermal-expansion coefficient, qhov loj-loj granite ua rau muaj kev cuam tshuam loj heev nyob rau hauv qhov sib txawv me me vim qhov ntev tag nrho. Diurnal khw-pem teb kub viav vias thiab hauv zos sib tsoo tshav kub tsim kub gradients thiab warpage.
UNPARALLELED ua tiav machining ntawm cov khoom loj loj hauv kev cob qhia qhov kub thiab txias nrog kev tswj qhov kub thiab txias. Optimized txias txo cov cua sov hloov mus rau hauv workpieces. Cov khoom yog tag nrho thermally sib npaug ua ntej sib tsoo thiab tshuaj xyuas kom tshem tawm cov ntawv nyeem tsis raug thiab thermal deformation tshwm sim los ntawm qhov sib txawv ntawm qhov kub thiab txias sab hauv.
5. Tso tawm-thiab-Tsev-Tsev-Tshaj Tawm: Tshaj Tawm Muaj Peev Xwm Rebound Deformation ua ntej
Kev tshem tawm tag nrho ntawm kev thim rov qab yog qhov nyuaj rau cov khoom loj loj. Kev xa ncaj qha tom qab machining yuav ua rau qhov tseeb drift raws li qhov seem kev ntxhov siab tso tawm maj mam tom qab kev cia zoo li qub.
UNPARALLELED txais yuav qhov "machining-stress-release-re-inspection-compensation-grinding" workflow. Tom qab ib nrab ua tiav, cov khoom ua haujlwm raug tshem tawm ntawm cov cuab yeej thiab muab tso rau hauv kev siv lub platform kom tso tawm clamping thiab machining kev ntxhov siab. Zuag qhia tag nrho flatness thiab geometric kam rau ua tau rov ntsuas dua. Me me rebound distortion yog kho los ntawm cov nyiaj them poob qis hauv kev sib tsoo rov ua dua. Deformation txaus ntshai yog daws nyob rau hauv tsev es tsis kis mus rau cov neeg muas zaub.
6. Kev Tshuaj Xyuas Tag Nrho Hauv Cheeb Tsam Ntau Qhov Chaw: Tshawb xyuas tag nrho cov kev cuam tshuam nrog cov ntawv nyeem tsim nyog hauv zos
Sparse sampling yooj yim nco lub ntiaj teb twist thiab ntev-span warpage. Me-zone flatness yuav dhau mus thaum micron-qib dabtsi yog khoov nyob rau hauv qhov ntev.
Cov cuab yeej tshuaj ntsuam xyuas loj yog siv rau qhov ntsuas qhov sib txawv ntawm qhov sib txawv ntawm qhov chaw ua haujlwm tag nrho los ntsuas tag nrho cov deformation tiam sis tsis yog kev ua haujlwm hauv cheeb tsam nkaus xwb. Tag nrho cov cuab yeej tshuaj xyuas tuav CNAS-traceable calibration daim ntawv pov thawj. Cov ntaub ntawv tshuaj xyuas raug xa ua ke nrog cov hauv paus rau cov neeg siv khoom siv thaum lub sijhawm ua tiav-tshuab sib dhos.
7. Kev tiv thaiv kev thauj mus los: Tiv thaiv qhov kev hloov pauv thib ob los ntawm qhov hnyav ntawm tus kheej thiab lub zog sab nraud
Txawm tias zoo kawg nkaus ua tiav cov hauv paus loj tuaj yeem raug kev txom nyem thib ob micro-deformation thaum lub sij hawm nqa, kev thauj mus los thiab ntim khoom vim qhov kev txhawb nqa tsis raug thiab kev kho tus kheej qhov hnyav.
Custom-made tooling yog saws. Cov ntsiab lus txhawb nqa tau npaj raws li cov txheej txheem kev faib khoom siv tshuab kom tsis txhob muaj kev thauj khoom ib leeg lossis ncua kev ncua ntev. Deformation raws li tus neeg tau txais kev pab tseem nyob ib puag ncig nrog lub Hoobkas-tested xwm txheej.
Muaj peev xwm xa khoom
UNPARALLELED tuav ISO9001, ISO14001, ISO45001, CE certifications thiab tshaj ib puas patents thiab trademarks. Muaj peev xwm tsim muaj peev xwm loj rau cov khoom siv granite loj ua kom muaj kev cai ua ntev mus ncig ntau lawm nrog 2 lub lis piam ua haujlwm. Peb xa cov granite ruaj khov siv cov kev daws teeb meem rau cov tuam txhab lag luam thoob ntiaj teb hauv cov khoom siv hluav taws xob, kev tshuaj xyuas qhov muag thiab kev ntsuas ntsuas kev lag luam.
Cov ntsiab lus
Micro-deformation ntawm qhov loj-loj granite hauv paus tsis tshua muaj tshwm sim los ntawm cov khoom tsis xws luag ib leeg; Nws tshwm sim los ntawm superposition ntawm seem seem kev nyuaj siab, clamping-yuam deformation, machining tshav kub thiab nws tus kheej-qhov hnyav deflection. Cov txheej txheem ua tiav npog lub voj voog ntev lub voj voog tsis muaj kev laus, hloov pauv cov cuab yeej tsis muaj zog, txheej sib tsoo, kev tsim hluav taws xob tas li, cov voj voog zoo li qub-tso-pab nyiaj thiab kev soj ntsuam tag nrho ntawm thaj chaw ua haujlwm tau zoo ua rau cov khoom ua haujlwm micron-theem deformation nyob rau hauv kev kam rau ua.
