Mainjiniya akamatchula zigawo za pulasitiki za makina oyendetsa ndege, nyumba zoyikamo zachipatala, kapena zida zogwirira ntchito za semiconductor, "fakitale yopangira makina apulasitiki yolondola" singosaka chabe - ndi chofunikira chosakambitsirana. Zololera zolimba kuposa ± 0.005 mm, pamwamba zimatha pansi pa Ra 0.4 µm, ndi zero warpage pambuyo pa kutseketsa kapena kupalasa njinga zotentha kumafunikira kuposa momwe masitolo wamba a CNC angabweretse. Tawona makasitomala akubwerera kuchokera kwa ogulitsa atatu omwe ali ndi magawo omwe adadutsa macheke-koma adalephera kuyesa kusindikiza kwa vacuum chifukwa cha ming'alu yaying'ono yakupsinjika kotsalira. Ndicho chifukwa chake kusiyanitsa kwenikweni sikuli zida chabe-ndi momwe khalidwe lakuthupi, njira zopangira zida, ndi kayendetsedwe ka chilengedwe zimayenderana mumayendedwe amodzi ophatikizika.
Chifukwa Chake Pulasitiki Sili "Chitsulo Chosavuta" -Ndipo Chifukwa Chake Maganizo Olakwikawa Amawononga Nthawi ndi Bajeti
Magulu ambiri ogula zinthu amaganiza kuti kupanga pulasitiki ndikosavuta kuposa chitsulo: mphamvu zochepetsera, palibe choziziritsa chomwe chikufunika, nthawi yozungulira mwachangu. Koma ntchito zamafakitale zamapulasitiki olondola zimakumana ndi zovuta zapadera zochokera ku fizikisi. Acrylics amakwawa pansi pa clamping pressure. PEEK imatenga chinyezi-kutupa mpaka 0.3% musanapange makina, ndiyeno imachepa mosadziwika bwino panthawi yowumitsa. Polycarbonate imafewetsa pa 140 ° C; chiphaso chimodzi chokhala ndi chip chosakwanira chikhoza kutulutsa kutentha komweko kokwanira kusungunula chigawo chodulidwa. Nthawi ina tidatsata gulu la ma lens olephera omwe adalephera kupita ku ma spikes a chinyezi panthawi yosungirako makina - osati pulogalamu ya CNC. Ichi ndichifukwa chake malo apamwamba amatengera mapulasitiki ngati zida zogwirira ntchito: mawonekedwe azinthu zoyendetsedwa ndi nyengo, kuyang'anira momwe kutentha kumagwirira ntchito, ndi njira zosinthira kutentha - osati kuthamanga kokha.
Maluso Anayi Osagonja Omwe Muyenera Kutsimikizira (Musanatumize Chojambula Chanu Choyamba)
Osadalira timabuku ta "CNC mphero" ndi "ISO 9001." Funsani mafunso anayi awa-ndipo funsani umboni:
- Kodi amatsimikizira kutsatiridwa kwa zinthu zambiri mpaka ASTM D638? Osati ziphaso za ogulitsa okha-zoyeserera zenizeni zochokera ku labotale yawo kapena gulu lina lovomerezeka. Tidapeza wogulitsa m'modzi wogwiritsa ntchito "PTFE yachipatala" yomwe idakumana ndi FDA 21 CFR koma idalephera mafotokozedwe a ASTM F758 biocompatibility chifukwa zodzaza zimasiyana m'magulu.
- Kodi angatsimikizire ma protocol okhazikika a kutentha? Magawo opangidwa kuchokera ku ndodo yotuluka ayenera kulumikizidwa mowongoleredwa * asanamalize * komaliza - apo ayi zovuta zamkati zimatulutsa pambuyo potumiza. Funsani nthawi yawo yonyowa / kutentha kwa Delrin® ndi Ultem®.
- Kodi amagwiritsa ntchito zida zokutidwa ndi diamondi kapena zolimba-carbide pamalo owoneka bwino okha? Zida zokhazikika za HSS zimasiya zilembo zazing'ono pa PMMA zomwe zimabalalitsa kuwala. Timayesa kukhulupirika kwapamtunda ndi interferometry yoyera-osati ma stylus profilometers okha.
- Kodi kutanthauzira kwa GD&T kumapangidwira kuunikanso uinjiniya-osati kumangoperekedwa kunja? Kuyitana kwa "malo enieni" panyumba yapulasitiki sikungokhudza malo okhawo. Zimatengera momwe ma shrinkage gradients amalumikizirana ndi ma mold line offsets. Ngati gulu lawo silingakuyendetseni pakuwunika koyipa kwambiri pogwiritsa ntchito data yanu yeniyeni ya CTE ya utomoni, chokani.
The Vertical Integration Gap Ogula Ambiri Amanyalanyaza
Izi ndi zomwe sizimawonekeranso pamasamba: "mafakitole olondola kwambiri apulasitiki" amapereka njira zofunika kwambiri. Amamakina—koma amatumiza zida ku shopu ina kuti azipaka nthunzi, electrostatic discharge (ESD) zokutira, kapena kuphatikiza zipinda zoyeretsa. Chiwopsezo chilichonse chimawonjezera chiwopsezo: kuipitsidwa, kugwedezeka kwapang'onopang'ono, kusawoneka bwino. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timayendetsa makina apulasitiki pambali pazitsulo zathu ndi mizere yoponyera - osati ngati madipatimenti osiyana, koma monga njira zolumikizirana. N’chifukwa chiyani zimenezi zili zofunika? Chifukwa kasitomala akafuna chigawo cha haibridi - valavu yachitsulo chosapanga dzimbiri yokhala ndi manja osindikizira a PEEK - timayika zida zonse papulatifomu yofananira ndi CMM, pogwiritsa ntchito mitundu yolipirira matenthedwe omwe amagawana. Palibe zongoyerekeza pakukula kosiyanasiyana pakuyesa magwiridwe antchito. Kuphatikizika kumeneko kumadula nthawi yotsogolera ndi 37% pamisonkhano yazinthu zambiri-ndipo kumachotsa 92% ya zolephera zokhudzana ndi mawonekedwe mu prototypes zama hydraulic system.
Kodi “Kulekerera Kwambiri” Kumatanthauza Chiyani M’kachitidwe (ndi Mmene Mungatchulire Molondola)
"Kulekerera kwakukulu" kuli kopanda tanthauzo popanda nkhani. Kulekerera kwa ± 0.01 mm pa bulaketi ya acrylic 50 mm ndi chizolowezi. Kulekerera komweko pa benchi ya 300 mm polycarbonate Optical? Izi zimafuna kukonza kwa vacuum-chuck, sub-1 µm spindle runout, ndi kugwetsa kwa nthawi yeniyeni kugwedezeka - chifukwa ngakhale kumveka kwapansi kuchokera kumafoloko apafupi amasuntha pulasitiki kuposa chitsulo. Timalangiza makasitomala kuti atchule kulolerana ndi *function*, osati kukula kwake: "Ayenera kusunga kufanana kwa 0.002 mm pakati pa malo okwerera pansi pa 200 kPa hydraulic load" kugunda "± 0.005 mm flatness." Izi zimatiuza komwe tingagawire zinthu za metrology-komanso ngati tingapangire zochepetsera kupsinjika kapena kusintha PEEK yodzaza magalasi kuti ikhale yosasunthika. Komanso: nthawi zonse tchulani momwe mungayesere. “Monga makina” sizitanthauza kanthu. "Kuyesedwa pa 23 ° C ± 1 ° C, 50% RH, maola 4 mutatha kuchotsedwa pamapaketi oyendetsedwa ndi nyengo" -ndizochita.
Kusankha fakitale yokonza makina apulasitiki yolondola sikutengera kufananiza mawu. Ndi za kutsimikizira yemwe ali ndi physics-kuchokera ku polymer crystallinity mpaka kupotokola kwa zida kupita ku chilengedwe. Wokondedwa woyenera samangokhala ndi kulolerana; amayembekezera momwe gawo lanu lidzakhalira m'malo ake omaliza. Ichi ndichifukwa chake mainjiniya pamakampani opanga zida zachipatala a Tier-1 ndi ma semiconductor OEM nthawi zonse amabwerera kumalo komwe pulasitiki simaganiziridwa pambuyo pake - amapangidwa mwamphamvu mofanana ndi ma turbine a superalloy. Kulondola kumayamba kalekale Chip choyamba chisanawuluke.
