Ultra-chaiyo inofamba module: Granite chaiyo base VS cast base.

Mukushandiswa kwe-ultra-precision motion module, hwaro, sechinhu chakakosha chekutsigira chikamu, inoita basa rakasimba mukuita kwemodule. Granite chaiyo base uye chigadziko chakakandwa vane hunhu hwavo, uye musiyano pakati pavo uri pachena.
I. Kugadzikana
Granite mushure memamiriyoni emakore ekuchinja kwe geological, chimiro chemukati chakaomeswa uye chakafanana, kunyanya nequartz, feldspar uye mamwe maminerari akanyatsobatanidzwa. Ichi chimiro chakasiyana chinochipa kugadzikana kwakanakisa uye chinogona kurwisa kupindira kwekunze. Mune yemagetsi chip yekugadzira workshop, midziyo yeperipheral inomhanya kazhinji, uye chigadziko chegranite chinogona kuderedza kuzunguzika kweyekupedzisira-chaiyo motion module inotumirwa kumhepo inoyangarara neinopfuura 80%, kuve nechokwadi chekufamba kwakanaka kwemodule uye kupa vimbiso yakasimba yemhando yepamusoro-chaiyo maitiro senge lithography uye etching yechip kugadzirwa.

Kunyangwe iyo base yekukanda inogona kuvharira vibration kusvika pamwero wakati, panogona kunge paine kumwe kukanganisa senge maburi ejecha uye pores mukuita kwekukanda, izvo zvinoderedza kufanana uye kugadzikana kwechimiro. Mukutarisana nepamusoro-frequency uye yakakwirira-simba vibration, iyo vibration attenuation kukwanisa haina kufanana negranite base, zvichiita kuti kusagadzikana kwekufamba kweiyo ultra-precision motion module yemhepo inoyangarara, iyo inokanganisa kugadzirisa uye kuona kurongeka kwemidziyo.
Chechipiri, kunyatsochengeta kuchengetedza
Granite thermal yekuwedzera coefficient yakadzikira zvakanyanya, kazhinji mu5-7 × 10⁻⁶/℃, munzvimbo yekushanduka kwekushisa, saizi shanduko ishoma. Mundima yekuongorora nyeredzi, iyo yekupedzisira-chaiyo yekufamba module yekunyatso-tuning yetelescope lens yakapetwa negirenati base, kunyangwe musiyano wetembiricha pakati pemasikati nehusiku wakakura, inogona kuona kuti kurongeka kwema lens kunochengetedzwa pachikamu che-sub-micron, zvichibatsira vanoongorora nyeredzi kuti vaone zviri kure mitumbi yedenga.
Chigadziko chekukanda chinowanzo shandiswa simbi zvinhu, senge simbi yakakandwa, kupisa kwekuwedzera coefficient yakakwira, ingangoita 10-20 × 10⁻⁶/℃. Kana tembiricha ichichinja, saizi inoshanduka zviri pachena, izvo zviri nyore kukonzeresa deformation ye-ultra-precision motion module yemhepo inoyangarara, zvichikonzera kuderera kwekufamba chaiko. Mune tembiricha-sensitive optical lens grinding process, deformation ye cast base pasi pesimba retembiricha inogona kukonzeresa kutsauka kwelens kugaya chaiko kupfuura iyo inobvumidzwa renji uye kukanganisa kunaka kwelens.
Chechitatu, kupfeka kuramba
Granite kuoma kwakakwirira, Mohs kuoma kunogona kusvika 6-7, yakasimba kupfeka kuramba. Murabhoritari yesainzi yemidziyo, iyo inogara ichishandiswa mhepo inoyangarara yekupedzisira-chaiyo inofamba module, granite base inogona kunyatso ramba kukweshera kwemhepo inotsvedza, kana ichienzaniswa neyakajairika base base, inogona kuwedzera kutenderera kweiyo module neinopfuura 50%, kuderedza mutengo wekugadzirisa midziyo, uye kuve nechokwadi kuenderera kwebasa resainzi rekutsvagisa.
Kana iyo yekukanda base yakagadzirwa neyakajairwa simbi zvinhu, kuoma kwacho kwakadzikira, uye pasi iri nyore kupfeka pasi penguva refu inodzokorodza kukweshera kwemhepo inotsvedza inotsvedza, iyo inokanganisa kufamba chaiko uye kutsvedzerera kweiyo yekupedzisira-chaiyo motion module yemhepo inoyangarara, inoda kakawanda kugadzirisa uye kutsiva, kuwedzera mutengo wekushandisa uye kudzika.
Chechina, mutengo wekugadzira uye kuomerwa kwekugadzirisa
Granite raw material yekutora mutengo wakakwira, migodhi, yekufambisa yakaoma, kugadzirisa kunoda hunyanzvi hwekushandisa uye tekinoroji, senge yakakwira-chaiyo kucheka, kugaya, kupukuta, nezvimwe, mitengo yakakwira yekugadzira. Uye nekuda kwekuoma kwayo kwepamusoro, brittleness, kuomerwa kwekugadzirisa, nyore kutaridzika kudonha kwemupendero, kutsemuka uye humwe hurema, chiyero chakakura chakakwira.
Iyo yekukanda base raw materials inowanikwa zvakanyanya, mutengo wakaderera, maitiro ekukanda akura, kuomerwa kwekugadzirisa kudiki, uye kugadzirwa kwakawanda kunogona kuitwa kuburikidza nekuumbwa, nepamusoro pekugadzira hunyanzvi uye mutengo unodzoreka. Nekudaro, kuti uwane iyo yakafanana yakakwirira chaiyo uye kugadzikana segiredhi base, maitiro ekukanda uye post-processing zvinodiwa zvakanyanya kuomarara, uye mutengo uchakwirawo zvakanyanya.
Muchidimbu, granite precision base ine bhenefiti yakakosha mumamiriro ekushandisa e-ultra-precision motion modules ane kurongeka kwepamusoro, kugadzikana uye kuramba kupfeka. Iyo yekukanda base ine zvimwe zvakanakira mumutengo uye kugadzirisa zviri nyore, uye inokodzera nguva apo kudiwa kwechokwadi kwakadzikira uye kutsvaga kwekugadzirisa mutengo kunoteverwa.
