Ishoramari rito ritanga ibice byuzuye byicyuma munsi ya garama 50 - akenshi bingana na 0.5 g - hamwe no kwihanganira kurenza mm 0,05 mm kandi ubuso burangirira kuri Ra 1,6 µm. Iyo intebe yawe ya hydraulic igomba gufunga kuri 420 bar, cyangwa cobalt alloy pump nozzle ikarokoka 800 ° C yumukino wo gusiganwa ku magare mugihe urwanya isuri ituruka kumashanyarazi, gushora imari mito ntabwo byoroshye. Nibikorwa byonyine bifite geometrie, imiterere yintete, na chimie muri lockstep kuri buri kintu.
Twakoze ibicuruzwa birenga 17,000 kuva muri 2019-cyane cyane AMS 5387 cobalt alloy nozzles, T800 ishingiye kuri shitingi ya shitingi, hamwe na pompe ya pompe ya piston idafite ibyuma munsi ya mm 32 muburebure. Muri buri cyiciro, tubona ukuri kumwe: guta ishoramari bisanzwe birananirana munsi ya 10 g. Inyangamugayo zisenyuka. Igishashara cyerekana ibishashara hejuru ya 3%. Ceramic shell permeability iratemba. Kuzuza ibyuma biba bitateganijwe. Niyo mpamvu "micro" itari mubunini gusa-ni bijyanye no kongera gukora urwego rwose rw'ibikorwa: gukora ibishashara, ibishishwa byubaka bikurikirana, dewax kinetics, igipimo cya preheat, hamwe no kugenzura gusuka.
Ibipimo bitatu bya tekiniki bitandukanya ishoramari ryukuri ryukuri guterwa no kugabanuka bisanzwe bisanzwe. Ubwa mbere, ibikoresho byerekana bigomba gukora kuri ± 1.5 µm gusubiramo - ntabwo ± 5 µm. Dukoresha ibyuma bya P20 bikomye hamwe nu mwobo wogosha amashanyarazi hamwe nibice byatewe nubushyuhe. Icya kabiri, sisitemu ya shell isaba ibyiciro bitanu byubaka: amakoti abiri yo gukaraba hamwe na subicron zircon, ibice bibiri hagati hamwe na silika yahujwe, hamwe numwenda wanyuma wububiko hamwe no gukwirakwiza ibice. Icya gatatu, gusuka bisaba kugenzura igihe nyacyo cyo kugenzura ubushyuhe muri ± 3 ° C - hamwe nu gipimo cya vacuum kiri kuri 0.08–0.12 mbar mugihe cyo kuzuza. Simbuka kimwe muri ibyo, uzabona cluster ya porosity hafi yinkuta zoroshye cyangwa irembo rituzuye ryuzuza ibintu biri munsi ya 0.8 mm.
Abakiriya bakunze kubaza bati: "Ntidushobora gusa CNC-imashini icyo gice aho?" Kuri geometrike zimwe - yego. Ariko tekereza kuri AMS 5387 cobalt alloy plug ifite urukuta rwa mm 0,6, umuyoboro wogukonjesha imbere, hamwe nubutaka butatu bwo gufunga. Gukora imyanda 82% by'ibikoresho fatizo. Ubuzima bwibikoresho bugabanuka kugera kuri 47 kuri karbide. Kandi guhangayikishwa cyane no gusya bitera 12 µm umuheto mukuvura ubushyuhe bwa nyuma. Micro ishoramari ritangira hafi-net imiterere. Turahita dushyira mugace ka 5-axis gusya gusa aho GD&T ihamagarira-nkisura yo gufunga cyangwa flange. Igisubizo? 63% igiciro gito cyibikoresho, 4.2 × igihe cyihuta cyigihe, hamwe na zeru zo gukwirakwiza micro-crack ziva mumashini yangijwe nubutaka.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yubatse ubushobozi bwayo bwo gushora imari hafi yubutumwa bukora-ntabwo ari amatsiko ya laboratoire. Buri kintu cyose kigizwe nubushakashatsi bwuzuye: umubare wubushyuhe, ibishashara, ibishishwa byubaka, gusuka inyandiko, na raporo ya CMM yashizwe kuri ASME Y14.5 GD&T guhamagarwa. Twemeza ituze ryikigereranyo hejuru yubushyuhe butatu (–40 ° C kugeza + 250 ° C) mbere yo kurekurwa. Ubusugire bwubuso bugenzurwa hakoreshejwe SEM-ibice-ntibigenzurwa gusa. Kandi yego - tugerageza buri kintu cyose cya T800 kivanze kugirango ikwirakwizwa rya cobalt dukoresheje ikarita ya EDS, kubera ko igipimo cya gamma-beta kidahuye kigira ingaruka ku buzima bw'umunaniro muri shitingi ya winch.
Micro ishoramari ikora neza iyo ihujwe na disipuline. Irinde inguni zimbere - koresha ≥0.3 mm radii. Komeza ibipimo by'urukuta munsi ya 3: 1. Kugaragaza umushinga gusa aho gufungura bisaba - 0,25 ° birahagije kubisasu byinshi bya zircon. Kandi ntuzigere utandukanya ibintu byoroheje: ubihuze na misa hamwe nudupapuro cyangwa imbavu zunganira igikonoshwa mugihe cya dewax. Turasubiramo buri gishushanyo cya castability mbere yo gusubiramo. Ukwezi gushize, twashyize ahagaragara 0.45 mm munsi yintebe yumuvuduko wumuvuduko waba wacitse igikonoshwa ceramic mugihe cya dewax. Kuvugurura byatwaye amasaha abiri. Yakijije umukiriya iminsi 11 na $ 8.400 mugikoresho cyakuweho.
Ibi ntabwo ari ukugabanya inzira zishaje. Nibyerekeye kubaka bundi bushya-layer kumurongo, micron na micron, byinshi kuri byinshi. Nkuko pompe ya peteroli isaba umuvuduko mwinshi, nkuko sisitemu ya hydraulic igabanuka muri robot zigendanwa, kandi nkuko amavuta ya cobalt-nikel asunika mu ibahasha ya serivisi 900 ° C, ishoramari rito riva muri niche rikenewe. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yibanze aho ibisobanuro bihuye ningaruka: ibice bidahuye gusa-ariko imikorere, kubaho, no gusubiramo. gushora imari iciriritse Itangira Gito. Irangirira aho kwizerwa bidashoboka.
