Buku Lotsogolera kwa Ogula Kwambiri: Momwe Mungasankhire Mbale Yokhala ndi Granite Mogwirizana ndi Miyezo ya DIN, ASME, ndi JIS

Mbale ya granite pamwamba ndiye maziko a muyeso wa miyeso. Ndiwo malo ofunikira kwambiri omwe miyeso ina yonse imayerekezeredwa. Koma si mbale zonse pamwamba zomwe zimapangidwa zofanana—ndipo si miyezo yonse yomwe ili yofanana. Ngati mukufuna kusankha mbale ya pamwamba ya labu ya metrology, dipatimenti yowunikira, kapena malo oyezera, kumvetsetsa kusiyana pakati pa miyezo ya DIN, ASME, ndi JIS sikungokhudza maphunziro okha. Ndi kusiyana pakati pa kugula mbale yomwe ikukwaniritsa zofunikira zanu ndi kugula yomwe siyikukwaniritsa zomwe mukufuna.

Miyezo Yoyang'ana Malo

Miyezo ingapo yapadziko lonse lapansi imayang'anira kulondola ndi kulinganiza kwa ma granite pamwamba pa mbale. Miyezo yomwe imadziwika kwambiri ndi iyi:

• DIN 876 (muyezo waku Germany), wokutira mapepala ophimba pamwamba kuti ayang'anire ndi kuyeza
• ASME B89.3.7 (muyezo waku America), womwe unalowa m'malo mwa wakale wa Federal Specification GGG-P-463C

• JIS B 7513 (muyezo wa ku Japan), wokutira mbale zapamwamba kuti muyeze molondola
• GB/T 20428 (muyezo wa Chitchaina)
• BS 817 (Muyezo waku Britain)

Muyezo uliwonse umafotokoza magiredi osiyanasiyana olondola, njira zoyesera, ndi zofunikira zovomerezeka. Mbale yomwe ikukwaniritsa DIN 876 Giredi 00 mwina singakwaniritse ASME B89.3.7 Giredi AA—ndi mosemphanitsa.

Kumvetsetsa Magiredi Olondola

Kulondola kwa mbale ya granite pamwamba nthawi zambiri kumafotokozedwa potengera kupirira kwa flatness pamwamba pa mbale yogwirira ntchito. Nayi kufananiza konse:

L = kutalika kwa mbale mu mm

Mfundo yofunika kwambiri: mbale yomwe ili ndi "Giredi 00" pansi pa DIN sikutanthauza kuti ndi "Giredi AA" pansi pa ASME. Njira zoyesera zimasiyana, malo oyezera amasiyana, ndipo njira zovomerezeka zimasiyana.

Zimene Muyenera Kuyang'ana Mu Mbale Yabwino Kwambiri

Kupatula kulondola kwa kalasi, zinthu zingapo zimatsimikiza ngati mbale ya pamwamba idzagwira ntchito momwe imayembekezeredwa pa nthawi yonse ya ntchito yake:

Ubwino wa Zinthu. Granite iyenera kukhala yopyapyala, yopanda zilema, komanso yofanana. Granite yotsika mtengo imatha kukhala ndi ma fractures ang'onoang'ono omwe amakhudza kukhazikika kwa nthawi yayitali. Ku ZHHIMG®, timagwiritsa ntchito granite wakuda wa ZHHIMG® wokhala ndi kuchulukira kwa ≈3100 kg/m³—wokwera kuposa granite wakuda ambiri aku Europe ndi America—kutsimikizira kukhazikika bwino komanso kukana kuwonongeka.

Kulimba ndi Kukana Kuwonongeka. Mbale ya pamwamba iyenera kukana kukanda ndi kuwonongeka chifukwa chogwiritsa ntchito mobwerezabwereza. Granite yathu imapeza kulimba kwa Mohs kwa 6-7, zomwe zimapangitsa kuti ikhale yolimba kwambiri kwa zaka zambiri ikugwiritsidwa ntchito tsiku ndi tsiku.

Kukhazikika kwa Kutentha. CTE ya granite iyenera kukhala yotsika komanso yodziwikiratu momwe ingathere. Granite yathu yakuda ya ZHHIMG® imapereka kukhazikika kwa kutentha kwapadera, kusunga kusalala pakati pa kutentha komwe kungapangitse mbale zachitsulo kupindika.

Kulinganiza ndi Kutsata. Mbaleyi iyenera kukhala ndi satifiketi yowunikira yomwe imatsatira miyezo kuchokera ku bungwe la dziko lonse la metrology. Ku ZHHIMG®, mbale iliyonse pamwamba imayesedwa pogwiritsa ntchito zida zovomerezeka ndi Jinan Institute of Metrology ndi Shandong Institute of Metrology, ndipo imatsatiridwa ndi National Institute of Metrology of China.

Udindo wa Luso la Ntchito Zaluso

Ngakhale granite yabwino kwambiri siigwira ntchito popanda kumalizidwa bwino.mbale ya pamwamba pa graniteZimaphatikizapo magawo awiri akuluakulu: kukonzekera kopanda kanthu ndi kukonza molondola. Chopanda kanthucho chimadulidwa mozungulira kuchokera pa chipika chogwetsedwa, kenako chimaphwanyidwa molondola mpaka kufika pamlingo wofanana. Koma gawo lomaliza—kukwaniritsa mulingo wokhazikika womwe watchulidwa—limafuna kulumikiza ndi manja mwaluso.

Akatswiri aluso amasintha mosamala pamwamba pa mbale kuti pakhale kusalala ndi kusalala kofunikira. Chidutswa chilichonse chiyenera kuyesedwa mosamala kuti chitsimikizire kuti chikukwaniritsa mulingo womwe watchulidwa. Ku ZHHIMG®, makina athu opukusira ali ndi zaka zoposa 30 zokumana ndi manja, zomwe zimapangitsa kuti pakhale kusalala kwa micrometer kudzera mu kukhudzidwa komwe palibe makina omwe angakope.

Malangizo Othandiza kwa Ogula

Poyerekeza mawu ochokera kwa opanga osiyanasiyana, musadalire dzina la chinthucho lokha. Pempho:

1. Kuchuluka kwenikweni kwa granite (osati "granite" yokha koma mtundu wake ndi kuchuluka kwake)
2. CTE (coefficient of thermal expansion) imayesedwa pa 20°C
3. Kulekerera kwa flatness komwe kwapezeka komanso muyezo womwe ukuyesedwa motsutsana nawo
4. Satifiketi yowunikira ndi zolemba zolondola
5. Chitsimikizo cha moyo wautumiki ndi ndondomeko yokonzanso mawonekedwe

Ngati wogulitsa sangathe kupereka tsatanetsatane uwu, ndiye kuti pali vuto lalikulu. Opanga ambiri ang'onoang'ono amagwiritsa ntchito miyala yotsika mtengo m'malo mwa miyala yeniyeni—mchitidwe wonyenga womwe timatsutsa mwamphamvu. Marble ndi yofewa, yosakhazikika, komanso yotha kutha kuposa granite yoyenera. Kusiyana sikochepa; ndi kusiyana pakati pa mbale ya pamwamba yomwe imasunga kulondola kwake kwa zaka zambiri ndi yomwe imachoka pamlingo winawake mkati mwa zaka zambiri.

Kukonza ndi Kukonzanso Chikalata

Plate ya granite pamwamba si ndalama yoti "muyikemo ndipo muiwale". Ngakhale mbale zabwino kwambiri zimafunika kubwezeretsanso nthawi ndi nthawi kuti zitsimikizire kuti sizinachoke pa kulekerera. ASME B89.3.7 imaphimba satifiketi yatsopano, kubwezeretsanso m'munda, ndi kubwezeretsanso pambuyo pokonzanso. DIN 876 ndi JIS B 7513 zili ndi zinthu zofanana.

Kusamalira nthawi zonse—kuyeretsa ndi zosungunulira zoyenera, kuteteza pamwamba kuti pasagwe, ndi kugwiritsa ntchito zophimba zoyenera pamene sizikugwiritsidwa ntchito—kumawonjezera nthawi yogwira ntchito ya pamwamba pa mbale. Ndipo pamene mbaleyo yatha kupitirira momwe imafunikira, kukonzanso pamwamba ndi katswiri wodziwa bwino ntchito kungathe kuibwezeretsa pamalo atsopano.

Ku ZHHIMG®, sitipanga ma plate apamwamba okha. Timapereka chithandizo chonse cha moyo—kuyambira pa specification yoyamba ndi calibration mpaka recertification ndi refacing—chifukwa timadziwa kuti plate pamwamba si chida chokha. Ndi maziko a dongosolo lanu lonse loyezera.
