Momwe Mungatsimikizire Kusalala kwa Granite Surface Plate

Mwayitanitsa mbale ya granite ya Giredi 00. Wogulitsayo akuti yavomerezedwa. Bokosi lafika. Mumasaina risiti yotumizira.

Patatha miyezi isanu ndi umodzi, woyang'anira khalidwe lanu amachita kafukufuku wa autocollimator nthawi zonse ndipo akuwona kuti mbaleyo yayamba kugwedezeka. Mumatsegula chikalata chopempha. Woperekayo akuloza siginecha yomwe ili pa risiti yanu yobweretsera.

Izi zimachitika kawirikawiri kuposa momwe ziyenera kukhalira. Sikuti chifukwa ogula ndi osasamala — koma chifukwa ogula ambiri sadziwa choti ayang'ane asanagule cholemberacho.

Bukuli limakupatsani njira zenizeni. Palibe zinthu zopanda pake. Mutha kupita nalo ku malo anu owunikira mawa.

TL;DR

Magiredi osalala (Giredi 00: ≤0.5μm/m, Giredi 0: ≤1μm/m, Giredi 1: ≤2μm/m) akuyimira kuchuluka kwenikweni kwa muyeso, osati zilembo zotsatsa. Musanasainire risiti iliyonse yotumizira: yesani mayeso a pepala ngati chipata choyamba chodutsa (mphindi 5-10), kenako chitani muyeso woyenera wa gridi ya autocollimator (mphindi 45-90). ZHHIMG® surface plate iliyonse imatumizidwa ndi German Mahr 0.5μm verification, Swiss WYLER electronic level confirmation, ndi Renishaw laser interferometer cross-check - zonse zomwe zingatsatidwe ku mabungwe a dziko lonse lapansi. Ngati kuwunika kwanu komwe kukubwera kwapeza vuto, lembani nthawi yomweyo ndi deta yanu yoyezera musanasayine.

Chifukwa Chake 70% ya Ogula a Kunja Sayang'ana Mbale Yawo Yapamwamba ya Granite Akafika

Ndiloleni ndikuuzeni zomwe zikuchitikadi pamene wina walandira.

Ogula ambiri ochokera kumayiko ena amakhulupirira satifiketi yoyezera ya wogulitsa. Amaganiza kuti labotale yachitatu kapena satifiketi yamkati ya wopanga ndi yokwanira. Amasaina, amapitiliza.

Vuto: satifiketi imeneyo inapangidwa masiku kapena milungu isanafike pansi panu. Paulendo - makamaka kutumiza zidebe kudzera m'njira za m'nyanja - ma granite pamwamba amatha kukumana ndi kutentha, kugwedezeka, komanso kukhudzidwa ndi thupi. Mapepala omwe adachoka ku fakitale amatha kufika pamalo anu mosadziwika bwino.

Ndaona ogula akupeza izi pamene potsiriza achita cheke chawo cha autocollimator panthawi yowunikira malo. Pofika nthawi imeneyo, nthawi yotumizira katundu yatsekedwa, nthawi yopempha katundu yatha, ndipo ali ndi mbale ya Giredi 00 ya $15,000 yomwe sangagwiritse ntchito pa ntchito ya Giredi 00.

Yankho si mantha. Ndi njira yowunikira ya mphindi 20 yomwe mungagwiritse ntchito ndi zida zoyambira.

Kumvetsetsa Giredi 00, Giredi 0, ndi Giredi 1: Kodi Manambala Amenewo Amatanthauza Chiyani mu Microns?

Musanatsimikizire kuti ndi yosalala, muyenera kudziwa zomwe mukufuna.

Magiredi osalala amafotokozedwa mu miyezo ingapo yapadziko lonse lapansi — DIN876, ASME B89, JIS, GB/T — ndipo onse amagwirizana pa mfundo yofanana. Umu ndi momwe magiredi amatanthauza:

Ndiloleni ndimasulire izi kukhala ziwerengero zenizeni.

Pa mbale yokhazikika ya 1000 × 630 mm (kukula kofala kwambiri komwe kumatumizidwa kunja), Giredi 00 imalola kusinthasintha konse kwa flatness kwa pafupifupi 1.5 μm pamwamba ponse. Izi ndi pafupifupi 1/50th ya m'mimba mwake wa selo lofiira la munthu. Giredi 0 imawirikiza kawiri mpaka pafupifupi 3 μm. Giredi 1 ili pafupifupi 6 μm.

Tsopano nayi zomwe ogula ambiri amaphonya: mfundo zake ndi pa mita imodzi ya kutalika kwa pamwamba, osati kupotoka konse kwa mbale.

Ngati mugula mbale ya 2000 × 1000 mm, kulekerera kwa kalasi kumagwira ntchito padera pa mita iliyonse yolunjika pamwamba. Kupatuka kwanu kovomerezeka kumawerengedwa kutengera kukula kwakutali. Pa mbale ya 2000 mm, mukuyang'ana pafupifupi 2.5 μm pa Giredi 00, 5 μm pa Giredi 0, ndi 10 μm pa Giredi 1.

Izi ndi ziwerengero zomwe mungathe kuziyeza. Ngati wina akukuuzani kuti mbale yake ya 2000 mm Giredi 00 ili ndi "pafupifupi ma microns atatu a kusiyana" - zimenezo zili mkati mwa spec. Ngati akunena kuti "pafupifupi ma microns 8" - ndilo gawo la Giredi 1, osati Giredi 00.

Dziwani bwino manambala musanasainire chilichonse.

Mayeso a Mzere wa Pepala: Njira Yachangu Yodziwira Katswiri Aliyense Ayenera Kudziwa

Kuyesa kwa pepala simuyeso wolondolaKoma ndi njira yachangu yothanirana ndi mavuto odziwikiratu musanawononge nthawi kukhazikitsa autocollimator.

Umu ndi momwe zimagwirira ntchito.
