A granite nto phajyog cov khoom siv ntsiag to tshaj plaws hauv txhua qhov chaw ntsuas ntsuas. Nws tsis txav. Nws tsis hum. Nws tsuas yog zaum ntawd, tuav lub dav hlau siv uas txhua qhov kev ntsuas hauv chav nyob ntawm. Qhov tseem ceeb ntawd yog lub ntsiab lus. Tab sis qhov flatness uas ua rau lub phaj nto trustworthy tsis yog ib qho cuab yeej ntawm lub pob zeb ib leeg - nws yog los ntawm kev xaiv cov khoom, tsim kev qhuab qhia, thiab calibration, txhua tus uas ntsiag to undo lwm tus yog hais tias carelessly.
Rau tus thawj tswj hwm zoo lossis tus kws kuaj sim, nkag siab tias qhov flatness ua tiav li cas yog qhov tseem ceeb. Nws yog qhov sib txawv ntawm kev yuav ib lub phaj thiab yuav khoom siv.
Vim li cas granite, thiab vim li cas dub granite tshwj xeeb
Granite yeej dhau cam khwb cia hlau rau ib qho yooj yim vim li cas: thermal stability. Ntuj granite nthuav ntawm kwv yees li 4.5 txog 8 × 10⁻⁶ ib℃Celsius, piv nrog txog 11 × 10⁻⁶ rau cam khwb cia hlau. Nyob rau hauv lub khw hauv pem teb uas ua pa los ntawm qhov kub thiab txias txhua hnub, lub phaj hlau ntsuas qhov cuam tshuam thaum lub phaj granite tuav nws cov duab geometry. Qhov qis expansion coefficient yog lub hauv paus ntawm txhua yam.regattagranitesindia
Txawm li cas los xij, tsis yog txhua tus granite sib npaug. Lub pob zeb cov qauv nplej thiab qhov porosity txiav txim siab seb nws yuav siv sij hawm ntev npaum li cas thiab ruaj khov npaum li cas nws nyob hauv qhov load. Dense, fine-grained black granite - the type Unparalleled sources for its plates - offers a combination of high density (around 3,100 kg/m³) and low porosity that resists chipping and holds an edge better than coarser, more porous stone. Nws yog kev xaiv cov khoom siv, tsis yog kev lag luam thov.
Cov qhab nia, thiab qhov lawv txhais tau li cas
Cov phaj saum npoo yog cais los ntawm kev ua siab ntev, thiab cov qib muaj txiaj ntsig ntau dua li cov neeg yuav khoom feem ntau paub. Raws li kev tswj hwm tus qauv - Tsoom Fwv Teb Chaws Specification GGG-P-463C, tam sim no hloov los ntawm ASME B89.3.7-2013, nrog rau DIN 876, JIS B7513, thiab BS 817 - kam rau ua kwv yees li ob npaug nrog txhua qib qib.
Qib AA / 00 (lab):lub flattest, tseg rau calibration thiab master reference ua hauj lwm. Qib AA phaj tuav lub tiaj tiaj ntawm qhov kev txiav txim ntawm ob peb microns thoob plaws nws qhov chaw ua haujlwm, thiab rau cov phaj me dua qhov kev ua siab ntev mus txog ib feem ntawm micron.
Qib A / 0 (kev tshuaj xyuas):lub workhorse ntawm chav tswj kom zoo, ntsuas qhov tseeb nrog tus nqi.
Qib B / 1 (toolroom):haum rau lub khw- hauv pem teb kev kuaj xyuas qhov twg ib puag ncig tswj tau txwv.
Lub tswv yim takeaway: ib phaj qib tsuas yog siv tau raws li nws cov calibration. ASME B89.3.7 tam sim no xav tau cov ntaub ntawv ntsuas qhov tsis paub tseeb thiab kev taug qab, tsis yog kev kuaj hla / tsis ua haujlwm. Lub phaj tsis muaj daim ntawv pov thawj calibration traceable yog ib lub pob zeb uas muaj daim ntawv lo zoo.
Qhov twg qhov flatness tiag los ntawm
Zaj dab neeg ntawm kev tsim khoom yog qhov ua ntej -kev paub ntawm tes cais qhov muaj peev xwm tiag tiag los ntawm daim ntawv thov. Lub phaj nto pib ua cov pob zeb ntxhib, txiav los ntawm cov pob zeb quarried thiab tom qab ntawd thermally hnub nyoog los txo cov kev ntxhov siab sab hauv - ib kauj ruam uas tiv thaiv lub phaj los ntawm maj mam warping xyoo tom qab xa khoom. Los ntawm qhov ntawd, kev sib tsoo precision coj qhov chaw ze rau lub hom phiaj, thiab tom qab ntawd kev ua haujlwm tiag tiag pib.unparalleled-pab pawg
Cov hauj lwm ntawd yog tes lapping. Cov kws tshaj lij kho qhov chaw siv peb - phaj txheej txheem, txhuam peb daim hlau tiv thaiv ib leeg ua ke kom tsuas yog ruaj khov, sib koom ua ke cov duab lawv tuaj yeem sib sau ua ke yog lub dav hlau tiag. Tsis muaj ib tug tswv ntseeg; lub geometry tshwm sim los ntawm tus txheej txheem nws tus kheej.
Qhov no yog qhov kev sib txuas. Unparalleled's lapping technicians nqa ntau tshaj peb caug xyoo ntawm tes-kev xyaum ua kom tiav, ua haujlwm rau micron- qib xav tau - kov uas qhia lawv tias pes tsawg microns ib qho dhau tau tshem tawm. Lub tuam txhab piav qhia txog nws cov grinders ua tiav hlau thiab tsis yog -hlau platforms ntev txog 6,000 mm ntev, thiab nws cov chav ntsuas ntsuas tau cais tawm ntawm kev vibration los ntawm kev tiv thaiv - vibration trenches thiab ntsiag to overhead cranes, yog li qhov kev ntsuas zaum kawg raug coj mus rau hauv ib puag ncig ruaj khov es tsis yog lub chaw ua haujlwm tsis khoom.
Calibration yog qhov kawg, yam tsawg kawg nkaus glamorous kauj ruam
Lub phaj tuaj yeem tsim tau zoo kawg nkaus thiab tseem ua tsis tiav hauv kev pabcuam yog tias kho tau raws li kev xav tom qab. Unparalleled txheeb xyuas qhov tiaj tus nrog cov qib hluav taws xob, autocollimators, thiab laser interferometers - tib cov twj siv los ntawm lub koom haum metrology hauv teb chaws - thiab nws cov cuab yeej nqa cov ntawv pov thawj calibration traceable rau lub teb chaws cov qauv.
Lub tuam txhab pab pawg cob qhia txhua xyoo tawm tsam DIN, ASME, JIS, GB, thiab BS cov qauv, thiab nws lub chaw tuav ISO 9001, ISO 14001, ISO 45001, thiab CE daim ntawv pov thawj. Tsis muaj qhov no ua rau lub phaj flatter. Qhov nws ua yog ua kom lub flatness thov trustworthy.
Kev ntsuas ntsuas
Nanometer- theem stability tsis yog ib qho kev ntsuas. Nws yog cov saw hlau - cov pob zeb ruaj khov, kev tsim cov kev qhuab qhia, kev muab qhab nia ncaj ncees, thiab kev ntsuas traceable - thiab lub phaj tsuas yog zoo li nws qhov tsis muaj zog txuas. Rau tus engineer lossis tus thawj tswj xyuas zoo xaiv qhov chaw siv, cov lus nug tsis yog seb lub phaj yog "nanometer qib." Nws yog seb txhua qhov txuas hauv cov saw hlau no puas tau sau tseg thiab tiv thaiv tau.
Qhov ntawd yog tus qauv Unparalleled tuav nws tus kheej daim hlau rau, thiab ib qho uas nws ntseeg tias kev lag luam yuav tsum tau txais los ntawm leej twg thov kom muab cov ntaub ntawv siv.
