Kodi chimango cholondola cha gantry ndi maziko a granite "zikugwirizana"? Mvetsetsani zinsinsi zazikulu mu nkhani imodzi.

Mu fakitale yomwe imapanga zigawo zolondola, chimango cha gantry cholondola cha XYZ chili ngati "super plotter", chokhoza kuyenda molondola pa sikelo ya micrometer kapena nanometer. Maziko a granite ndi "tebulo lokhazikika" lomwe limathandizira "plotter" iyi. Kodi angagwiredi ntchito mogwirizana bwino akaphatikizidwa? Lero, tiyeni tivumbulutse chinsinsi chomwe chili mkati.
N’chifukwa chiyani amanenedwa kuti ndi “ogwirizana bwino”?
Granite si mwala wamba. Ili ngati "msilikali wankhondo wa hexagonal" m'dziko la zinthu:

Mphamvu yabwino kwambiri yoyamwa ma shock: Granite ili ndi mphamvu zambiri, ndipo kapangidwe kake kamkati kali ngati "tight jigsaw puzzle". Pamene gantry frame ikuyenda mofulumira ndikugwedezeka (monga momwe imagwedezera ikagwedezeka mwadzidzidzi ikathamanga), granite imatha kuyamwa mphamvu yoposa 90% ya kugwedezeka, zomwe zimathandiza kuti gantry frame "iyime mwamphamvu" mwachangu. Mwachitsanzo, pogaya magalasi owoneka bwino, mutagwiritsa ntchito maziko a granite, kugwedezeka kwa gantry frame kunachepetsedwa kuchoka pa 15 microns kufika pa 3 microns, ndipo kulondola kwa magalasi kunasintha kwambiri.
Osaopa "kusokonezeka" kwa kutentha: Chimango cha gantry chidzatentha pambuyo pa ntchito yayitali. Zipangizo wamba "zidzakula ndi kusokonekera" zikatenthedwa, koma kuchuluka kwa kutentha kwa granite ndi gawo limodzi mwa magawo asanu okha a chitsulo! Ngakhale kutentha mu workshop kutasintha ndi 10℃ mkati mwa tsiku limodzi, kusintha kwake kumatha kunyalanyazidwa. Chingathe kuthandizira kwambiri chimango cha gantry ndikuwonetsetsa kuti cholakwika cha malo sichidutsa ma microns awiri.

Kodi nawonso "adzakhala ndi mikangano"? Nkhani izi ziyenera kukumbukiridwa!
Ngakhale kuti "zimagwirizana kwambiri", ngati sizinakonzedwe bwino pachiyambi, "kusagwirizana ndi chilengedwe chapafupi" kungachitikenso:

Manyazi a "ma interfaces osafanana"
Ma slider ndi ma guide rails pa gantry frame ayenera kuyikidwa bwino m'mabowo a maziko. Ngati kupotoka kwa mabowo pa maziko kupitirira 0.01 millimeters (koonda kuposa tsitsi la munthu), gantry frame ikhoza kupendekeka ikayikidwa ndikukakamira ikasunthidwa. Monga momwe zimakhalira pamene ma jigsaw puzzle sakugwirizana, ngakhale mutayesetsa bwanji, sizigwira ntchito.
Kuopsa kobisika kwa "kusagwirizana kwa kulemera"
Mafelemu akuluakulu a gantry ndi olemera komanso "olimba". Ngati maziko a granite si olimba mokwanira (ndi mphamvu yopondereza yochepera 120 megapascals), amatha kusweka chifukwa cha kupanikizika kwakukulu kwa nthawi yayitali. Izi zili ngati kuthandizira mwala waukulu wokhala ndi nthambi zazing'ono. Posachedwapa, udzasweka.
Vuto la "kukulitsa ndi kufupika kwa kutentha kosasinthasintha"
Mlingo wa mafelemu a zitsulo ndi granite zomwe zimakula zikatenthedwa ndi wosiyana. Mu malo omwe kutentha kumasiyana kwambiri, awiriwa amatha "kupikisana" kuti apange kupsinjika, zomwe zimapangitsa kuti zidazo zisakhazikike, monga momwe zidapangidwira ndi zipangizo zosiyanasiyana "zikuyendera njira yawoyawo" kutentha kwambiri.
Kodi mungawapangitse bwanji "kugwirizana bwino"?
Musadandaule. Pali njira zothetsera mavuto awa:

Maziko Opangidwa Mwapadera: Yesani kulemera kwa chimango cha gantry, malo oyika mabowo ndi zina zambiri pasadakhale, ndipo lolani wopanga asinthe maziko apadera kuti atsimikizire kuti cholakwika cha malo aliwonse a bowo sichidutsa mamilimita 0.005.
Limbikitsani ndikusintha maziko: Sankhani granite yokhala ndi mphamvu yopondereza kwambiri (≥150 megapascals), komanso pangani kapangidwe ka uchi mkati mwa maziko, monga momwe njuchi zimakhalira, zomwe sizingochepetsa kulemera kokha komanso zimawonjezera mphamvu yonyamula katundu.
Ikani "Temperature Control Guardian": Onjezani gasket yosinthasintha pakati pa maziko ndi chimango cha gantry kuti muchepetse kutentha; Kapena ikani mapaipi oziziritsira madzi kuti kutentha kusasinthe mkati mwa 1℃.
