Mufekitori inogadzira zvikamu zvakanyatsonaka, furemu yeXYZ chaiyo yakaita se "super plotter", inokwanisa kufamba zvakanyatsonaka pa micrometer kana kunyange nanometer scale. Gwaro regranite ndiro "tafura yakagadzikana" inotsigira "plotter" iyi. Vanogona here "kushanda pamwe chete" kana vakabatana? Nhasi, ngatibudisei chakavanzika chiri mukati.
Sei zvichinzi "zvinowirirana zvakakwana"?
Granite harisi dombowo zvaro. Rakafanana ne "murwi ane mapoinzi matanhatu" munyika yezvinhu:
Kugona kukuru kwekunyudzwa kweshock: Granite ine density yakanyanya, uye chimiro chayo chemukati chakaita se "tight jigsaw puzzle". Kana gantry frame ichifamba nekukurumidza uye ichidedera (sekunge inodedera seinobhururuka nekukasira ichimhanya), granite inogona kunyudza anopfuura 90% yesimba re vibration, zvichiita kuti gantry frame "imire yakasimba" nekukurumidza. Semuenzaniso, pakugaya optical lenses, mushure mekushandisa granite base, shaken amplitude ye gantry frame yakaderedzwa kubva pa15 microns kusvika pa3 microns, uye kurongeka kwemalenzi kwakavandudzika zvikuru.
Usatya "kukanganiswa" kwekupisa: Furemu ye gantry ichapisa mushure mekushanda kwenguva refu. Zvinhu zvakajairika "zvinokura uye zvinokanganisika" kana zvapiswa, asi thermal expansion coefficient ye granite inongova chikamu chimwe muzvishanu chesimbi! Kunyangwe tembiricha iri muworkshop ikachinja ne10℃ mukati mezuva, deformation yayo inogona kuregeredzwa. Inogona kutsigira furemu ye gantry zvakasimba uye kuona kuti positioning error haipfuure 2 microns.
Vachavawo "nemakakatanwa" here? Nyaya idzi dzinofanira kucherechedzwa!
Kunyange zvazvo "zvichienderana zvikuru", kana zvisina kurongwa zvakanaka pakutanga, "kusawirirana nemamiriro ekunze emuno" kunogonawo kuitika:
Kunyara kwekuti "interfaces hadzina kufanana"
Maslider nemaguide rails ari pa gantry frame zvinofanira kuiswa nemazvo mumaburi echigadziko. Kana kutsauka kwemaburi ari pachigadziko kukadarika 0.01 millimeters (kutetepa kupfuura bvudzi remunhu), gantry frame inogona kutsveyama kana yaiswa uye kunamatira kana yafambiswa. Kungofanana kana majoini ejigsaw puzzle asingawirirane, zvisinei nekuti unoedza sei, hazvishande.
Njodzi yakavanzika ye "kusaenzana kwehuremu"
Mafuremu makuru egantry anorema uye "akasimba". Kana hwaro hwegranite husina kusimba zvakakwana (nesimba rekudzvanya riri pasi pe120 megapascals), hunogona kutsemuka kana hukamanikidzwa kwenguva refu. Izvi zvakafanana nekutsigira dombo guru rine matavi madiki. Nokufamba kwenguva, richatsemuka.
Dambudziko re "kuwedzera kwekupisa uye kudzikira kwekupisa kusingaenderane"
Mwero wekukura kwemafuremu esimbi negranite kana zvichipiswa wakasiyana. Munzvimbo ine musiyano mukuru wekupisa, zviviri izvi zvinogona "kukwikwidzana" kuti zvigadzire kushushikana, zvichiita kuti michina isagadzikane, kungofanana nezvikamu zvakagadzirwa nezvinhu zvakasiyana "zvichienda nenzira yazvo" pakupisa kwakanyanya.
Maitiro ekuita kuti "vashande pamwe chete zvakakwana"?
Usazvidya moyo. Kune mhinduro dzematambudziko aya:
Hwaro hwakagadzirwa nenzira yakakodzera: Yera huremu hwefuremu yegantry, nzvimbo dzemaburi ekuisa uye rumwe ruzivo pachine nguva, uye rega mugadziri agadzirise hwaro hwakatsaurirwa kuti ave nechokwadi chekuti kukanganisa kwenzvimbo yega yega yeburi hakupfuuri 0.005 millimeters.
Simbisa uye simudzira hwaro: Sarudza granite ine simba rekudzvanya rakakwirira (≥150 megapascals), uye gadzirawo chimiro cheuchi mukati mehwaro, sezvinoita mukoko wenyuchi, izvo zvisingangoderedzi huremu chete asiwo zvinowedzera kugona kwekutakura mutoro.
Isa "Temperature Control Guardian": Wedzera gasket rinochinjika pakati pehwaro nefuremu yegantry kuti ubvise kushushikana kwekupisa; Kana kuisa mapaipi ekutonhodza mvura kuti tembiricha irambe iri mukati me1℃.
