Iyo abajenjeri bagaragaje ibice bya pulasitiki kubikoresho byo mu kirere, amazu yatewe mu buvuzi, cyangwa ibikoresho byo gukoresha wafer ya semiconductor, "uruganda rukora imashini zitunganya plastike" ntabwo ari ijambo ryishakisha gusa-ni ibisabwa bidashoboka. Kwihanganirana kurenza mm 0.005 mm, ubuso burangirira munsi ya Ra 0.4 µm, hamwe na zeru zeru nyuma yo kuboneza urubyaro cyangwa gusiganwa ku magare bikenerwa kuruta amaduka asanzwe ya CNC ashobora gutanga. Twabonye abakiriya bagaruka kubacuruzi batatu bafite ibice byatsinze igenzura-ariko byananiye ibizamini byo gufunga vacuum kubera micro-crack zatewe no guhangayika. Niyo mpamvu itandukaniro nyaryo atari ibikoresho gusa-nuburyo imyitwarire yibintu, ingamba zinzira, hamwe no kugenzura ibidukikije bihurira kumurimo umwe uhuriweho.
Kuki Plastike Atari "Icyuma Cyoroshye" gusa -Kandi Impamvu Iyo myumvire itari yo itwara igihe ningengo yimari
Amatsinda menshi yamasoko atekereza ko gutunganya plastike mubisanzwe byoroshye kuruta ibyuma: imbaraga zo gukata hasi, nta coolant ikenewe, ibihe byihuta. Ariko imikorere yinganda zitunganya plastike zihura nimbogamizi zidasanzwe zishingiye kuri fiziki. Acrylics iranyerera munsi yigitutu. PEEK ikurura ubuhehere - kubyimba kugera kuri 0.3% mbere yo kuyitunganya, hanyuma igabanuka bitateganijwe mugihe cyumye. Polyakarubone yoroshye kuri 140 ° C; inzira imwe ifite imitwaro idahagije irashobora kubyara ubushyuhe bwaho bihagije kugirango ushonge agace kaciwe. Twigeze gushakisha icyiciro cya optique ya optique yananiwe kugera kubushyuhe bwibidukikije mugihe cyo kubika mbere yo gutunganya-ntabwo ari gahunda ya CNC. Niyo mpamvu ibikoresho byo mu rwego rwo hejuru bifata plastiki nkibikoresho bifatika: kubika ibikoresho fatizo bigenzurwa n’ikirere, kugenzura ubushyuhe bw’ibikorwa, hamwe n’ibikoresho byifashishijwe mu gukwirakwiza ubushyuhe - ntabwo byihuta gusa.
Ubushobozi Bune butaganira ugomba kugenzura (Mbere yo kohereza Igishushanyo cyawe cya mbere)
Ntukishingikirize ku gatabo kerekana "gusya CNC" na "ISO 9001." Baza ibi bibazo bine - hanyuma usabe ibimenyetso:
- Ese bemeza ibintu byinshi bikurikirana kugeza kuri ASTM D638 raporo zingutu? Ntabwo abatanga ibicuruzwa gusa - amakuru yikizamini avuye muri laboratoire yabo cyangwa abandi bantu bemewe. Twabonye umucuruzi umwe ukoresheje "ubuvuzi-bwo mu rwego rwa PTFE" bwahuye na FDA 21 CFR ariko binanirwa na ASTM F758 biocompatibilité kuko ibiyuzuza byari bitandukanye mubice.
- Bashobora kwerekana protocole yumuriro? Ibice bikozwe mu nkoni yakuweho bigomba gukorerwa annealing * mbere yuko * birangira-bitabaye ibyo guhagarika umutima birekura nyuma yo koherezwa. Baza igihe cyokunywa / ubushyuhe bwumurongo wa Delrin® na Ultem®.
- Bakoresha ibikoresho bisize diyama cyangwa bikomeye-karbide kubikoresho byo murwego rwa optique? Ibikoresho bisanzwe bya HSS bisiga micro-amarira kuri PMMA ikwirakwiza urumuri. Dupima ubusugire bwubuso hamwe na interterometrie yera-ntabwo ari stylus profilometero gusa.
- Ubusobanuro bwa GD&T bwubatswe mubushakashatsi bwubuhanga - ntabwo bwatanzwe? Ihamagarwa "imyanya nyayo" kumazu ya plastike ntabwo ari ahantu honyine. Nukuntu uburyo bwo kugabanya gradients zikorana numurongo wa offsets. Niba itsinda ryabo ridashobora kugutambutsa muburyo bubi bwo gusesengura ukoresheje imibare yawe ya CTE yukuri, genda.
Icyuho cyo Guhuza Icyuho Abaguzi Benshi birengagiza
Dore ibidakunze kugaragara kurubuga: "inganda zikora plastike zuzuye" zitanga intambwe zikomeye. Bakora imashini - ariko bohereza ibice mu rindi duka ryo gusiga imyuka, gusohora amashanyarazi (ESD), cyangwa guteranya ubwiherero. Buri ntoki yongeramo ibyago: kwanduza, gutembera kugipimo, kubura gukurikiranwa. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dukora imashini ya pulasitike iruhande rwibyuma no kumirongo - ntabwo ari amashami atandukanye, ariko nkibikorwa bifitanye isano. Kuki ibyo bifite akamaro? Kuberako mugihe umukiriya akeneye ibice bivangavanze-umubiri wibyuma bidafite ingese hamwe nibikoresho bya PEEK bifatanyirijwe hamwe - dukoresha ibikoresho byombi kumurongo umwe wa CMM-Calibrated, dukoresheje uburyo bwo kwishyura ubushyuhe bwumuriro. Nta gukeka kubyerekeye kwaguka gutandukanye mugihe cyo kugerageza imikorere. Uku kwishyira hamwe kugabanya igihe cya 37% kumateraniro yibikoresho-kandi bikuraho 92% byananiranye bijyanye ninteruro muri sisitemu ya hydraulic.
Niki "Kwihanganirana cyane" bivuze mubyukuri mubikorwa (nuburyo bwo kubigaragaza neza)
"Kwihanganirana cyane" ntacyo bivuze nta murongo. Kwihanganira ± 0.01 mm kuri 50 mm ya acrylic bracket ni gahunda. Kwihanganirana kimwe kuri 300 mm ya polikarubone ya optique? Ibyo bisaba guhuza vacuum-chuck, sub-1 µm spindle runout, hamwe nigihe cyo kunyeganyega kugihe-kuko na resonance ituruka hasi kuva kuri forklifts yegeranye ihindura plastike kuruta ibyuma. Turagira inama abakiriya kwerekana kwihanganira * imikorere *, ntabwo ari urugero gusa: "Tugomba gukomeza guhuza 0.002 mm hagati yubusabane hagati ya 200 kPa hydraulic umutwaro" ikubita "± 0.005 mm." Ibyo biratubwira aho twagenera ibikoresho bya metrologiya-kandi niba twasaba inama yo kugabanya imihangayiko cyangwa guhinduranya PEEK yuzuye ibirahuri kugirango bikomere. Na none: burigihe vuga imiterere yo gupima. “Nkimashini” ntacyo bivuze. "Gupimirwa kuri 23 ° C ± 1 ° C, 50% RH, nyuma y'amasaha 4 ukuwe mu bikoresho bipfunyika ikirere" - ibyo birakorwa.
Guhitamo uruganda rutunganya plastike neza ntabwo ari ukugereranya amagambo. Nukugenzura uwaba afite physics-kuva polymer kristalline kugeza guhinduranya ibikoresho kugeza hystereze yibidukikije. Umufatanyabikorwa mwiza ntabwo yihanganira gusa; barateganya uko igice cyawe kizitwara mubidukikije byanyuma. Niyo mpamvu abajenjeri bo mu bigo byubuvuzi bya Tier-1 hamwe na OEMs ba semiconductor bahora basubira mubikoresho aho plastiki itatekerejweho-ikozwe nuburemere bumwe na superalloy turbine. Icyitonderwa gitangira kera mbere yuko chip ya mbere iguruka.
