Tataiso ea Mochini le Tlhokomelo ea Granite Surface Plate: Poleite e nepahetseng ea holim'a granite e hloka mochini o khethehileng le tlhokomelo ho netefatsa ho nepahala le ho phela halelele. Pele o benya, karolo ea granite e tlameha ho etsoa ts'ebetsong ea mochini oa pele le tokiso e otlolohileng e ipapisitseng le melaoana ea boemo ba khutlotharo. Ka mor'a ho sila ka holimo, haeba mochine oa CNC o sitoa ho finyella ho nepahala ho hlokahalang-hangata ho finyella ho nepahala ha Kereiti ea 0 (ho mamellana ka 0.01mm/m joalo ka ha ho boletsoe ho DIN 876) - ho qetela ka letsoho hoa hlokahala bakeng sa ho fumana limaraka tse holimo tse nepahetseng joalo ka Kereiti ea 00 (0.005mm/m mamello ho latela maemo a ASTM77).3.
Ts'ebetso ea mochini e kenyelletsa mehato e 'maloa ea bohlokoa. Taba ea pele, ho sila ka likhoka ho theha boreleli ba mantlha, 'me ho lateloe ke semi-finishing ho tlosa matšoao a machining. Ho sila ka mokhoa o nepahetseng, hangata ho etsoang ka letsoho, ho ntlafatsa holim'a metsi ho finyella mamello e lakatsehang ea flatness le holimo holimo (Ra boleng ba 0.32-0.63μm, moo Ra e emelang ho kheloha ha lipalo ho bolela ho kheloha ha boemo bo holimo). Qetellong, tlhahlobo e hlokolosi e tiisa hore e lumellana le litekanyetso tsa tekheniki, tse nang le lintlha tsa tekanyo tse behiloeng ka mokhoa o hlophisitsoeng ho pholletsa le li-diagonal, metse, le li-midline-hangata lintlha tse 10-50 ho itšetlehile ka boholo ba poleiti - ho netefatsa tlhahlobo e ts'oanang ea ho nepahala.
Ho sebetsana le ho kenya ho ama haholo ho nepahala. Ka lebaka la ho tiea ha granite (Mohs hardness 6-7), ho phahamisa ka mokhoa o sa lokelang ho ka baka ho senyeha ho sa feleng. Bakeng sa lits'ebetso tsa bohlokoa tse hlokang ho nepahala ha Kereiti ea 00, ho roala letsoho ka mor'a ho kenya letsoho ho bohlokoa ho khutlisetsa ho nepahala ho senyehileng nakong ea lipalangoang. Tlhokomelo ena ea lintlha e khetholla lipoleiti tse holimo tsa granite tse nepahetseng ho tsoa liphetolelong tse tloaelehileng tsa mochini.
Mekhoa ea tlhokomelo e ama ka ho toba tshebetso le nako ea bophelo. Qala ka ho hloekisa ka ho feletseng ka ho sebelisa lihloeki tsa pH tse sa jeleng paate - qoba lintho tse nang le asiti tse ka hlabang bokaholimo. Tekanyetso ea selemo le selemo ka li-interferometer tsa laser, tse latelloang ho latela litekanyetso tsa NIST, li netefatsa ho nepahala ho tsoelang pele. Ha u beha li-workpieces, lumella ho lekanngoa ha mocheso (ka tloaelo metsotso e 15-30) ho thibela liphoso tsa tekanyo ho tloha ho fapana ha mocheso. Le ka mohla u se ke ua thella lintho tse makukuno ka holim'a metsi, kaha sena se ka baka likhoele tse nyane tse amang ho bata.
Litaelo tse nepahetseng tsa tšebeliso li kenyelletsa ho hlompha meeli ea mojaro ho thibela ho senyeha ha sebopeho, ho boloka maemo a tsitsitseng a tikoloho (mocheso oa 20 ± 2 ° C, mongobo 50 ± 5%), le ho sebelisa lisebelisoa tsa ho phahamisa tse inehetseng ho qoba tšenyo ea sefofane. Ho fapana le lisebelisoa tsa tšepe, botsitso ba mocheso oa granite (0.01ppm/°C) bo fokotsa tšusumetso ea tikoloho, empa liphetoho tsa tšohanyetso tsa mocheso li ntse li lokela ho qojoa.
E le sesebelisoa sa motheo ho precision metrology, lipoleiti tsa granite tse netefalitsoeng (ISO 17025 e ngolisitsoe ka molao) li sebetsa e le litekanyetso tsa litšupiso bakeng sa litekanyo tsa litekanyo. Tlhokomelo ea tsona e hloka boiteko bo fokolang—ho hlakola feela ka lesela le se nang lint ka mor’a ho sebelisoa—ha ho hlokahale litlolo tse khethehileng kapa mafura. Ka ho latela liprothokholo tsena tsa machining le tlhokomelo, lipoleiti tsa granite tse nepahetseng li fana ka ts'ebetso e tšepahalang ka lilemo tse mashome, e leng se etsang hore e be tsa bohlokoa haholo lilaboratoring tsa calibration, tlhahiso ea lifofane, le lits'ebetso tsa boenjiniere tse nepahetseng haholo.
