Pankhani ya makina olondola a CNC, opanga zida ambiri amayesa maziko achitsulo ndi granite. Funso lomwe limafunsidwa ndi mainjiniya nthawi zambiri: kodi kusintha kolondola kwa makina kungatheke bwanji posintha maziko achitsulo chachikhalidwe ndi a granite? Palibe chiwerengero chokhazikika cha kulondola kolondola. Zimatengera kusinthasintha kwa kutentha, kutentha kotsika, kugwedezeka, ndi kukula kwa ntchito. Komabe, ubwino wofunikira wa maziko a granite umachotsa zopinga zingapo zazikulu zomwe zimalepheretsa kulondola kwa CNC.
Maziko a chitsulo chopangidwa ndi chitsulo ali ndi zovuta zake. Zitsulo zimakhala ndi ma coefficients okwera kwambiri okulitsa kutentha. Kutentha komwe kumachitika chifukwa chodula spindle mosalekeza komanso kusintha kwa kutentha kwa usana ndi usiku m'ma workshop kumapangitsa kuti maziko afutukuke komanso afupike, zomwe zimapangitsa kuti makina ayambe kuyenda. Kupatula apo, chitsulo chopangidwa ndi chitsulo chimasuntha mosavuta kugwedezeka. Kugwedezeka pang'ono kuchokera pakudula kupita ku nsonga ya chida ndikusiya zizindikiro pamalo omalizidwa. Kusakalamba mokwanira kumabweretsanso kusintha pang'onopang'ono pakapita nthawi. Zolakwika zomwe zimasonkhanitsidwa nthawi zambiri zimaletsa kulondola kwa CNC wamba mkati mwa micrometer, zomwe zimapangitsa kuti makina a sub-micrometer akhale ovuta kuwasamalira.
Makina a CNC atagwiritsa ntchito maziko a granite olondola a ZHHIMG, kusintha kumayamba ndi kukhazikika kwa kutentha. Granite wakuda wosankhidwayo ali ndi kuchuluka kochepa kwambiri kwa kutentha. Kusintha kwake kwa kukula kumakhala kochepa kwambiri pansi pa kutentha kodula komanso kusintha kwa kutentha kwa malo, zomwe zimachepetsa kwambiri zolakwika zomwe zimachitika chifukwa cha kutentha. Pansi pa kusintha kofanana kwa kutentha, kusintha kwa kutentha kwa maziko a granite kumatha kutsika ndi 70% poyerekeza ndi kapangidwe ka chitsulo chopangidwa ndi chitsulo. Chiyambi cha makina chimakhala chokhazikika kwa maola ambiri, kuchepetsa kusintha kwa nthawi zambiri komanso kubwezeretsanso.
Kuchepetsa kugwedezeka ndi chinthu china chofunikira kwambiri. Granite ili ndi mphamvu yabwino kwambiri yochepetsera kugwedezeka, yomwe imayamwa mwachangu kugwedezeka kuchokera ku kuzungulira kwa spindle mwachangu komanso kudula zida kuti ichepetse kugwedezeka. Kugwedezeka koyendetsedwa bwino, kuyenda kwa nsonga ya chida kumatsatira njira yongopeka bwino, kutsirizika kwa pamwamba pa workpiece kumakula bwino ndipo kulondola kwa contour kumawonjezeka. Pakukonza bwino kwa nkhungu, ziwalo za kuwala ndi zigawo za semiconductor, phindu la kuchepetsa kugwedezeka limawonekera kwambiri.
Komabe, kukula kwa kulondola kumasiyana malinga ndi momwe ntchito ikuyendera. M'ma workshop wamba okhala ndi kutentha kosakhazikika, kusinthana ndi maziko a granite nthawi zambiri kumawonjezera kulondola kobwerezabwereza komanso kulondola kwa contour ndi 30% ~ 50%. M'ma workshop olamulidwa ndi kutentha kwa CNC yolondola kwambiri, kusintha kulondola kokhazikika kumatha kupitirira 60%, zomwe zimapangitsa kuti machining a sub-micrometer azikhala okhazikika. Tiyenera kudziwa kuti maziko a granite ndi omwe amayendetsa bwino kwambiri. Zotsatira zomaliza za machining zimadalirabe njira zoyendetsera zapamwamba, ma linear motors, ma gratings olondola komanso kusonkhana koyenera. 
Kupatula kulondola kwachangu, kukhazikika kwa nthawi yayitali ndi chinthu china chomwe chimawonetsa maziko a granite. Granite yakale kwambiri yatulutsa kupsinjika kwamkati. Mosiyana ndi chitsulo chopangidwa ndi chitsulo, sichimasuntha pakapita nthawi. Kapangidwe ka maziko kamakhalabe kofanana ngakhale patatha zaka zambiri akugwira ntchito. Kulondola kumachepa pang'onopang'ono kuposa mabedi achitsulo wamba, zomwe zimachepetsa ndalama zokonzera ndi kukonzanso ntchito pakapita nthawi.
ZHHIMG, yokhala ndi ukadaulo wopanga zinthu zopangidwa ndi granite komanso zida zonse zowunikira za metrology yapadziko lonse lapansi, imapereka maziko a granite ophatikizidwa ndi mafelemu a gantry a makina osiyanasiyana a CNC, kuyambira mphero zazing'ono zopangira zinthu zolondola mpaka makina akuluakulu a gantry CNC. Opanga zida zolondola kwambiri amagwiritsa ntchito njira zothetsera mavuto a granite. Amagwiritsa ntchito ubwino wachilengedwe wa zinthuzo kuti achepetse zolakwika za kutentha ndi kugwedezeka komwe kumachokera ndikutsegula mphamvu zonse zogwirira ntchito za zida za CNC.
