Matebulo opangidwa ndi miyala ya granite amakhazikika pamisonkhano yamiyala yolondola - osati ngati malo ogwirira ntchito, koma ngati nsanja pomwe chowonadi chowoneka bwino chimakumana ndi zinthu zakuthupi. Tawona masitolo akutaya 12% ya zokolola za slab kuchokera ku tebulo flex pansi pa CNC gantry katundu; ena amasiya 3-4 m'mphepete patsiku chifukwa chotsekera chotchinga chalephera pa bar 0,8. Izi sizololera zamalingaliro. Ndi zotayika zatsiku ndi tsiku zomwe zimalowetsedwa m'mabuku apansi pamasitolo ku Ohio, Ontario, ndi Omsk.
Chifukwa Chake Granite—Osati Chitsulo Kapena Konkire—Imapambana Pakupanga Mwala
Mphamvu yopondereza ya granite imaposa 200 MPa. Mphamvu yake yowonjezera kutentha imakhala pa 0.000008 / ° C - zosakwana theka la aluminiyumu, gawo limodzi mwa magawo asanu a chitsulo chochepa. Pamene mlatho wa CNC umayenda pa 1.2 m / s pa mtunda wa mamita 3, ngakhale 0.02 mm ya matenthedwe osuntha amadula ma angles kupitirira ± 0.15 ° kulolerana. Tidayezera izi pamalopo: kugwedezeka kwa 30 ° C kozungulira kunapangitsa kuti 0.07 mm patebulo lachitsulo la 40-mm-koma 0.013 mm pa maziko a granite 120 mm. Kusiyana kumeneko kumalekanitsa kubwereza kwa m'mphepete ndi kukonzanso.
Matebulo opangira ma granite enieni amagwiritsa ntchito midadada yogoba, yochepetsera kupsinjika, osapanga ma polima opangidwa ngati miyala. Mapangidwe a tirigu ayenera kukhala ofanana, opanda ma micro-fractures omwe amadutsa pamtunda. Timayesa slab iliyonse ndi ultrasonic pulse-echo tisanapange makina: kuthamanga kwa phokoso pansi pa 3,200 m / s kumasonyeza voids mkati. Ma slabs okha omwe akugunda 3,450-3,600 m/s ndi omwe amapanga mndandanda wathu womaliza wodula.
Vuto la umphumphu ndilofunika kwambiri kuposa mphamvu yoyamwa yaiwisi. Gome lovotera 95 kPa silitanthauza kanthu ngati geometry ya tchanelo itsikira pa 70 kPa. Protocol yathu yotsimikizira imayesa kuchuluka kwa kuwonongeka: kukakamizidwa kuyenera kugwira ≥85 kPa kwa mphindi 10 mutasindikiza madoko onse. Ndiko kucheperako kukana kukameta ubweya wotsalira panthawi ya chida cha diamondi.
Zina Zinayi Zosakambirana (Zothandizidwa ndi Field Data)
Titafufuza malo opangira 47 ku North America ndi ku Europe, tidasokoneza zinthu zinayi zomwe zimalekanitsa ma tebulo ogwira ntchito ndi ngongole zodula:
Kulekerera kwa flatness ≤0.05 mm/m-zotsimikiziridwa ndi ma flats optical ndi interferometry, osati zowongoka Integrated T-slot grid ndi phula la 20-mm, lopangidwa ndi makina olondola ± 0.02 mm Ma modular vacuum zones (osachepera 16 pa tebulo 3 × 2 m), iliyonse ili ndi mavavu odzipatula okha Thermal mass stabilization: makulidwe osachepera 120 mm kwa matebulo osapitilira 4 m kutalika; 150 mm pamawonekedwe akuluakulu Makasitomala m'modzi ku Wisconsin adalowa m'malo mwa tebulo la konkriti "premium" patatha miyezi isanu ndi umodzi. Routa yawo ya CNC idayamba kuyenda pang'onopang'ono. Kuyanjanitsa kwa laser kunavumbulutsa 0.18 mm sag kudutsa Y-axis - chifukwa cha kuyamwa kwa chinyezi kumatupa gawo lapansi. Granite inathetsa kusintha kumeneku. Zokolola zawo za sabata yoyamba zidalumpha 8.3%.
Umphumphu Wakuthupi Siwosankhira—Kumayesedwa
Botou Haijun Metal Products Co., Ltd. sipanga matebulo a granite. Koma timapereka zitsulo zofunikira kwambiri zomwe zimawapangitsa kuti azigwira ntchito: zolowetsa T-slot m'makina olondola, mavacuum zitsulo zosapanga dzimbiri, ndi mafelemu othandizira a CNC opangidwira ziro resonance pa 120 Hz—kuchuluka kwa macheka ambiri amwala.
Zida zathu zimatsimikiziridwa ndi magawo atatu: certification yazinthu zopangira (malipoti oyesa mphero a SS304/316L), kuwunika kwa CMM pambuyo pa makina (± 0.01 mm pamalo onse opezeka), ndikuyendetsa njinga zavacuum (mizungu 10,000 pamagetsi a 1.2 bar). Timakana 4.7% ya ma billets omwe akubwera potengera kuyesa kwamphamvu kokha-chifukwa mphamvu zokolola pansi pa 520 MPa zimawononga kuwonongeka kwapang'onopang'ono.
Opanga ena amayika matebulo mwachindunji pansi pa konkriti. Malingaliro oipa. Talemba kugwedezeka kwapansi kukulirakulira pa 18 Hz-kufanana ndi ma frequency achilengedwe a machitidwe ambiri a gantry. Malingaliro athu? Dzipatulani ndi ma neoprene pads (Shore A 60 hardness) ndikutsimikizira kusamuka <0.005 mm pachimake mpaka pachimake pogwiritsa ntchito laser Doppler vibrometry.
Kusankha Gome Lanu: Funsani Mafunso Asanu Awa Musanasaine
Musanayitanitsa, funsani sapulani wanu:
Kodi mungapereke mamapu amtundu wa interferometric-osati "m'kati mwazoneneratu"? Kodi chiwopsezo chenicheni cha vacuum pagawo lililonse, choyezedwa pa ISO 10292 ndi chiyani? Kodi T-slot channels CNC-makina khwekhwe limodzi-kapena welded ndi pansi? Kodi mumatsimikizira bwanji kukhazikika kwamafuta? (Funsani ma graph a delta-T vs. Kodi ndi chiani chotalika kwambiri chopitirirabe chomwe chinakonzedwa pamakonzedwe enieni a tebulo ili-ndipo kulekerera m'mphepete kunali kotani? Tawona zolemba zikutsika 22% pomwe ogula amafuna zenizeni m'malo mwa timabuku. Wogulitsa wina ku Europe adasinthiratu ogulitsa atazindikira kuti tebulo lawo "lolondola" adagwiritsa ntchito zida zosungidwa - zowoneka ngati mbewu zosagwirizana poyang'aniridwa ndi 100-lux LED.
Matebulo opanga miyala ya granite sasintha kudula-amawathandiza. Amasintha kachidindo ka CNC kukhala chowonadi chenicheni. Ngati ntchito yanu yotsatira ikufuna ± 0.05 mm m'mphepete mwa 3 cm quartzite, yambani ndi nsanja yomwe imangokhala pomwe china chilichonse chikuyenda. Pulatifomuyo imayamba ndi granite, kutsika kotsimikizika, ndi kusakhulupirika kwa vacuum komwe mungathe kuyeza - osaganiza. Pazolemba zaukadaulo pazida zoyimilira zomwe zimagwirizana ndi mawonekedwe a vacuum, pitani https://www.haijunmetals.com.
