Hauv ntiaj teb ntawm kev tsim khoom siv precision, metrology, thiab kev tsim khoom siab heev, qhov tseeb tsis yog lub hom phiaj xwb - nws yog qhov tsim nyog kiag li. Hauv plawv ntawm qhov tseeb no yog ib qho cuab yeej tseem ceeb: lub phaj saum npoo. Thaum cov hlau cam khwb cia thiab cov phaj hlau tau ua lub luag haujlwm hauv cov chaw ua haujlwm, granite tau tshwm sim ua cov khoom siv xaiv rau cov chaw niaj hnub, qhov tseeb siab. Txawm li cas los xij, tsis yog txhua lub phaj saum npoo granite tau tsim sib npaug. Txhawm rau kom ntseeg tau tias koj qhov kev ntsuas muaj kev ncaj ncees, nws yog qhov tseem ceeb kom nkag siab txog tus qauv thoob ntiaj teb: DIN 876.
Phau ntawv qhia no yuav coj koj mus rau qhov tseem ceeb ntawm DIN 876, pab koj taug kev ntawm ntau qib sib txawv thiab xaiv lub phaj granite zoo meej rau koj cov kev xav tau tshwj xeeb hauv kev lag luam.
Vim li cas Granite yog qhov kev xaiv zoo tshaj plaws rau Precision
Ua ntej yuav nkag siab txog cov qauv kev siv tshuab, nws yog ib qho tseem ceeb kom nkag siab tias vim li cas granite thiaj yog cov khoom siv zoo tshaj plaws rau cov phaj nto uas muaj qhov tseeb siab. Cov khoom siv ntawm granite muaj cov txiaj ntsig zoo dua li lwm cov hlau, ua rau nws zoo tagnrho rau cov chaw uas qhov ruaj khov thermal thiab qhov tseeb mus sij hawm ntev yog qhov tseem ceeb.
Ua ntej tshaj plaws, granite yog ib yam khoom uas tawv heev. Cov granite zoo siv hauv kev ntsuas feem ntau muaj Mohs hardness ntawm 6 txog 7, uas nyuaj dua li cov hlau uas tau tawv. Qhov no ua kom qhov chaw no tiv taus kev hnav thiab kev sib txhuam, thiab tseem ua kom nws ruaj khov txawm tias nyob hauv chaw ua haujlwm uas tibneeg coob. Tsis zoo li hlau, granite tsis muaj hlau nplaum thiab tsis coj hluav taws xob, uas tshem tawm kev cuam tshuam thaum ntsuas hluav taws xob lossis hlau nplaum.
Tej zaum qhov zoo tshaj plaws yog granite lub thermal stability. Nws muaj cov coefficient qis ntawm thermal expansion thiab thermal conductivity qis. Qhov no txhais tau tias qhov kub thiab txias hloov pauv muaj qhov cuam tshuam tsawg kawg nkaus rau qhov loj ntawm lub phaj, thiab cov cua sov hauv zos (xws li los ntawm tes ntawm tus neeg ua haujlwm lossis ib qho khoom sov tso rau ntawm lub rooj) dissipates qeeb qeeb thiab sib npaug, tiv thaiv kev cuam tshuam. Ntxiv mus, granite yog ntuj tsim tsis xeb thiab tiv taus cov kua qaub, ua kom lub neej ntev nrog kev saib xyuas tsawg kawg nkaus. Qhov tseem ceeb tshaj plaws, granite qib siab yog cov qauv sib xws thiab tsis muaj kev ntxhov siab sab hauv, txhais tau tias nws tiv taus kev khoov thiab ntswj dhau sijhawm.
Kev txhais cov qauv DIN 876
DIN 876 yog tus qauv kev lag luam German uas teev cov kev cai rau cov phaj granite nto. Nws tau lees paub thoob ntiaj teb ua tus qauv rau qhov zoo hauv kev ntsuas. Tus qauv hais txog txhua yam los ntawm hom pob zeb siv mus rau qhov txwv ntawm qhov tiaj tiaj.
Tus qauv no faib cov phaj granite ua plaub qib sib txawv ntawm qhov tseeb. Kev xaiv qib kom raug yog qhov sib npaug ntawm qib kev raug koj xav tau thiab cov peev nyiaj uas koj muaj. Feem ntau, qib siab dua ntawm qhov tseeb, tus nqi siab dua vim yog cov neeg ua haujlwm ntau uas xav tau rau cov txheej txheem lapping thiab scraping zoo.
Qib 00: Tus Qauv Hauv Chav Kuaj Mob
Qib 00 sawv cev rau qhov siab tshaj plaws ntawm qhov tiaj tiaj thiab qhov tseeb. Cov phaj nto uas ua tau raws li tus qauv no yog tsim nrog cov kev kam rau siab tshaj plaws thiab yog siv rau hauv cov chaw tswj hwm, xws li cov chaw soj ntsuam thiab cov chav ntsuas. Yog tias koj txoj haujlwm cuam tshuam nrog kev lees paub lwm yam cuab yeej ntsuas lossis ua cov kev ntsuas qhov tseeb uas txawm tias ib qho micron ntawm qhov yuam kev tsis lees txais, Qib 00 yog koj qhov kev xaiv xav tau. Cov phaj no tsis tshua pom ntawm lub Hoobkas pem teb vim muaj kev pheej hmoo ntawm kev puas tsuaj thiab kev tsis ruaj khov ntawm ib puag ncig.

Cov phaj nto uas ua tau raws li tus qauv no yog tsim nrog cov kev kam rau siab tshaj plaws thiab yog siv rau hauv cov chaw tswj hwm, xws li cov chaw soj ntsuam thiab cov chav ntsuas. Yog tias koj txoj haujlwm cuam tshuam nrog kev lees paub lwm yam cuab yeej ntsuas lossis ua cov kev ntsuas qhov tseeb uas txawm tias ib qho micron ntawm qhov yuam kev tsis lees txais, Qib 00 yog koj qhov kev xaiv xav tau. Cov phaj no tsis tshua pom ntawm lub Hoobkas pem teb vim muaj kev pheej hmoo ntawm kev puas tsuaj thiab kev tsis ruaj khov ntawm ib puag ncig.
Qib 0: Tus Qauv Kev Ua Haujlwm Precision
Qib 0 yog tus qauv rau cov chav cuab yeej ua haujlwm siab thiab cov chaw tshuaj xyuas hauv chaw tsim khoom. Txawm hais tias nws tsis nruj npaum li Qib 00, nws tseem muaj qhov tiaj tiaj zoo heev. Qib no zoo meej rau kev cim cov khoom ua haujlwm raug, tshuaj xyuas cov khoom ua haujlwm siab, thiab teeb tsa cov khoom siv ua haujlwm rhiab heev. Nws txuas qhov sib txawv ntawm qhov zoo tshaj plaws ntawm lub chaw kuaj mob thiab qhov xav tau ntawm cov kab ntau lawm.
