Buku Lokwanira Lokonza Granite Surface Plate: Momwe Mungakulitsire Nthawi Yowerengera

Malo osungira miyala ya granite salephera kugwira ntchito mokweza. Palibe phokoso lophwanyika, palibe kuwala kochenjeza, palibe chizindikiro chodziwikiratu chakuti kuphwanyika kwatha chifukwa cha kulekerera. Imangokhala pamenepo ikuwoneka yosalala monga momwe inalili patsiku loperekera, mpaka wogwiritsa ntchito CMM atazindikira vuto lobwerezabwereza lomwe limabwerera mmbuyo - pambuyo pa theka la tsiku lovuta la kuthetsa mavuto - mpaka pamalo ofunikira. Zokhumudwitsa zambiri zimapewedwa, ndipo zambiri zimadalira zizolowezi zomwe sizikugwirizana ndi khalidwe la granite.

Chifukwa Chake Granite Imatuluka Ngakhale Palibe Amene Akuikhudza

Kutayika kwa flatness pambale ya pamwambaKawirikawiri si kuwonongeka kwakukulu chifukwa cha chochitika chimodzi. Ndikokwanira: njira zogwiritsidwa ntchito m'deralo, kuyeretsa kosagwirizana, kutentha kwa mpweya, ndipo - nthawi zambiri kuposa momwe ma lab amayembekezera - chithandizo chosayenera. Mbale yomwe ili pa benchi losagwirizana, kapena yomwe imathandizidwa pamalo olakwika poyerekeza ndi madera ake onyamula katundu, idzagwa pang'onopang'ono kwa miyezi ingapo. Granite ndi yokhazikika poyerekeza ndi chitsulo, koma "yokhazikika" sikutanthauza "yotetezeka ku fizikisi." Kuchulukana ndikofunikira pano; miyala yolimba kwambiri, yomwe ili pamtunda wa 2,900–3,100 kg/m³, imakonda kusunga nthaka yake bwino ikanyamula katundu wokhazikika kuposa zinthu zotsika zomwe zimakhala ndi ma porosity ambiri amkati, chomwe ndi chifukwa chimodzi chomwe si "granite wakuda" yonse yomwe imachita chimodzimodzi pa moyo wautumiki wazaka zisanu.

Kuyeretsa: Zochepa ndi Zambiri, Koma Chitani Bwino

Cholakwika chachikulu chomwe tikuchiwona kuchokera kumunda si kunyalanyaza - ndi kuyeretsa koopsa kwambiri. Zosungunulira zomwe sizinayesedwe ngati granite, nsalu zokwawa, kapena kupukuta kouma komwe kumakoka grit pamwamba zonse zimapangitsa kuti pakhale kukanda pang'ono komwe kumasonkhana mpaka kusinthasintha kwenikweni pakapita nthawi. Chotsukira granite chopanda pH, nsalu yopanda lint, ndi kukhudza pang'ono zimapita kutali kwambiri kuposa momwe anthu amayembekezera. Zinyalala zouma ziyenera kuchotsedwa, osati kukokedwa. Ngati mbale ikugwiritsidwa ntchito kwambiri tsiku ndi tsiku, kupukuta mwachangu posintha shift ndikofunikira kuposa kuyeretsa kwambiri kamodzi pamwezi.

Kusunga ndi Kuyang'anira Zachilengedwe

Kusintha kwa kutentha ndi chinthu chachiwiri chachikulu, ndipo apa ndi pomwe ma lab ambiri amaika ndalama zochepa poyerekeza ndi bajeti ya zida zomwe adagwiritsa ntchito kale. Mbale yosungidwa kapena kugwiritsidwa ntchito m'chipinda chomwe chimasinthasintha tsiku lililonse cha 5–10°C imagwira ntchito yokha isanayesedwe ngakhale kamodzi. M'malo athu owerengera ndi osonkhanitsira, zigawo za granite zimasamalidwa m'zipinda zoyendetsedwa ndi kutentha ndi chinyezi - osati chifukwa chakuti zinthuzo sizingapulumuke kusintha kwa malo, koma chifukwa kusunga kulekerera kwa flatness kwa zaka zambiri kumafuna kuchotsa kusinthako konse m'malo molipira pambuyo pake. Kwa ma lab ambiri amafakitale, kuwongolera kwathunthu nyengo sikoyenera, koma kusunga mbale kutali ndi ma HVAC vents, kuwala kwa dzuwa mwachindunji, ndi zida zomwe zimapanga kutentha kwapafupi ndi njira yotsika mtengo ya mfundo yomweyo.

Kugawa ndi Kusamalira Katundu

Mbale iliyonse ya pamwamba ili ndi malo othandizira, ndipo imayika kunja kwa malo amenewo - ngakhale kwakanthawi, ngakhale ndi chinthu chowoneka chopepuka - imayambitsa kupsinjika komwe granite sinapangidwe kuti inyamule mofanana. Izi zimachitika panthawi yogwiritsidwa ntchito komanso panthawi yonyamula. Kukweza mbale molakwika, kapena kuisiya kuti ipumule mosagwirizana panthawi yosuntha, ndi chifukwa chofala komanso chopewera cha kubwezeretsanso koyambirira.

Chomwe Chimawonjezera Nthawi Yowerengera

Kusinthasintha kwa nthawi yowunikira sikokhazikika; kumasonyeza lingaliro la kuchuluka kwa madzi omwe amayendetsedwa bwino. Ma labu omwe amakulitsa nthawiyo amachita zinthu zitatu nthawi zonse: kuwongolera kusintha kwa malo, kuyeretsa bwino komanso nthawi zonse m'malo mochita zinthu mwamphamvu komanso nthawi zina, komanso kusunga njira zoyenera zothandizira ndi kuwongolera. Palibe chilichonse mwa izi chomwe chimalowa m'malo mwa kuwunikira - zimangotanthauza kuti mbaleyo ikhoza kukhalabe yovomerezeka tsiku lowunikira likafika, m'malo mofuna kuyang'aniridwa kwakanthawi kosakonzekera.

Kutsata bwino ndikofunikira pano. Zikalata zoyezera ziyenera kubwerera ku bungwe lodziwika bwino la dziko lonse la metrology, ndipo ndikofunikira kutsimikizira kuti aliyense amene akuyesa plate yanu - kaya ndi gulu lamkati lomwe limagwiritsa ntchito mulingo wovomerezeka wamagetsi kapena labu yakunja - amatsatira muyezo wodziwika bwino monga DIN 876, ASME B89.3.7, kapena JIS B7513, m'malo mwa njira yosavomerezeka yamkati. Timayesa kutulutsa kwathu kwa granite motsutsana ndi satifiketi ya Jinan ndi Shandong metrology institute, ndi kutsata bwino malinga ndi miyezo ya dziko, makamaka chifukwa makasitomala omwe amagula ma plate ofunikira amafuna zikalata zomwe angapereke kwa owerengera awo popanda kuyitananso.

Poyambira Pabwino

Palibe chilichonse mwa izi chomwe chimafuna kukonzanso labu. Yambani ndi njira yoyeretsera, yang'anani komwe mbaleyo imathandizidwa poyerekeza ndi komwe ikuyenera kukhala, ndipo yang'anani zomwe zili pafupi nayo zomwe zimapangitsa kutentha. Kusintha pang'ono pano nthawi zonse kumaposa kukonzanso kobwerezabwereza, ndipo kumawononga ndalama zochepa poyerekeza ndi chochitika chosakonzekera cha CMM chomwe chimachitika chifukwa cha malo owonetsera omwe palibe amene ankaganiza kuti angawafunse.
