Hanyar gogewa na ƙirar filastik

Gyaran injina

Gyaran injina hanya ce mai gogewa wacce ta dogara da yankan da nakasar filastik na saman kayan don cire ɓangarorin da aka goge don samun ƙasa mai santsi. Gabaɗaya, ana amfani da sandunan dutsen mai, ƙafafun ulu, takarda yashi, da sauransu, kuma aikin hannu shine babbar hanyar. Ana iya amfani da sassa na musamman kamar saman jikin mai juyawa. Yin amfani da kayan aikin taimako irin su turntables, za a iya amfani da polishing ultra-daidaici ga waɗanda ke da buƙatun ingancin saman ƙasa. Ultra-daidaici polishing shine amfani da kayan aikin abrasive na musamman, waɗanda aka matse su tam akan saman da aka sarrafa na aikin a cikin wani ruwa mai gogewa wanda ke ɗauke da abrasives don jujjuyawar sauri. Yin amfani da wannan fasaha, za a iya cimma raƙuman ruwa na Ra0.008μm, wanda shine mafi girma a cikin hanyoyi daban-daban na gogewa. Motoci na gani na gani sau da yawa suna amfani da wannan hanyar.

Chemical polishing

gyare-gyaren sinadarai shine a sanya ɓangaren abin da ke cikin matsakaicin sinadari ya narke da kyau fiye da ɓangaren maƙarƙashiya, ta yadda za a sami wuri mai santsi. Babban fa'idar wannan hanyar ita ce, baya buƙatar kayan aiki masu rikitarwa, yana iya goge kayan aiki tare da sifofi masu rikitarwa, kuma yana iya goge kayan aiki da yawa a lokaci guda, tare da ingantaccen inganci. Babban matsalar gogewar sinadarai shine shirya ruwa mai gogewa. Ƙaƙƙarfan saman da aka samu ta hanyar gogewar sinadarai gabaɗaya μm 10 ne.

Electrolytic polishing

Ainihin ka'idar gyaran gyare-gyaren lantarki iri ɗaya ce da ta gyare-gyaren sinadarai, wato, ta hanyar zaɓen narkar da ƴan ƙanana da ke saman kayan don yin santsi. Idan aka kwatanta da sinadaran polishing, sakamakon cathode dauki za a iya kawar da, da kuma sakamako ne mafi alhẽri. Tsarin polishing electrochemical ya kasu kashi biyu matakai: (1) Matsayin macroscopic A narkar da kayayyakin da aka narkar da a cikin electrolyte, da geometric roughness na abu surface ragewa, Ra> 1μm. ⑵ Ƙaramar haske mai haske: Anode polarization, an inganta haske mai haske, Ra <1μm.

Ultrasonic polishing

Saka da workpiece a cikin abrasive dakatar da kuma sanya shi tare a cikin ultrasonic filin, dogara a kan oscillation sakamako na ultrasonic, sabõda haka, abrasive ne kasa da goge a saman da workpiece. Ultrasonic machining yana da ƙananan macroscopic ƙarfi kuma ba zai haifar da nakasawa na workpiece, amma yana da wuya a yi da kuma shigar kayan aiki. Ultrasonic aiki za a iya hade tare da sinadaran ko electrochemical hanyoyin. Dangane da lalatawar bayani da electrolysis, ana amfani da vibration na ultrasonic don tayar da maganin, don haka samfuran da aka narkar da su a saman kayan aikin sun rabu, kuma lalata ko electrolyte kusa da farfajiyar su ne uniform; da cavitation sakamako na ultrasonic a cikin ruwa kuma iya hana lalata tsari da kuma sauƙaƙe surface haskakawa.

Gyaran ruwa

Gyaran ruwa ya dogara da ruwa mai gudu mai sauri da ɓarke ​​​​da ke ɗauke da shi don wanke saman kayan aikin don cimma manufar gogewa. Hanyoyin da aka fi amfani da su sune: sarrafa jet abrasive, sarrafa ruwa jet, hydrodynamic nika da sauransu. Hydrodynamic nika ana kore ta na'ura mai aiki da karfin ruwa matsa lamba don sanya ruwa matsakaici dauke da abrasive barbashi gudãna da baya da kuma fitar a fadin saman workpiece a high gudun. Matsakaicin yawanci an yi shi ne da mahadi na musamman (kamar abubuwa masu kama da polymer) tare da kyawawan kwararar ruwa a ƙarƙashin ƙananan matsa lamba kuma gauraye da abrasives. Abrasives za a iya yi da silicon carbide foda.

Magnetic nika da polishing

Magnetic abrasive polishing shi ne don amfani da Magnetic abrasives don samar da goge goge a ƙarƙashin aikin filin maganadisu don niƙa aikin. Wannan hanya tana da ingantaccen sarrafawa, inganci mai kyau, sauƙin sarrafa yanayin sarrafawa da yanayin aiki mai kyau. Yin amfani da abrasives masu dacewa, ƙarancin saman zai iya kaiwa Ra0.1μm. 2 Gyaran injina bisa wannan hanyar polishing ɗin da aka ambata a cikin sarrafa gyare-gyaren filastik ya bambanta sosai da gogewar da ake buƙata a wasu masana'antu. Magana mai mahimmanci, polishing na mold ya kamata a kira aikin madubi. Ba wai kawai yana da manyan buƙatu don goge kanta ba, har ma yana da manyan ma'auni don shimfidar ƙasa, santsi da daidaiton geometric. Gyaran fuskar gabaɗaya yana buƙatar fili mai haske kawai. Ma'aunin sarrafa saman madubi ya kasu kashi huɗu: AO = Ra0.008μm, A1 = Ra0.016μm, A3 = Ra0.032μm, A4 = Ra0.063μm. Yana da wahala a daidaita daidaitattun daidaiton lissafi na sassa saboda hanyoyin kamar walƙiya na lantarki da gogewar ruwa. Duk da haka, da surface ingancin sinadaran polishing, ultrasonic polishing, Magnetic abrasive polishing da sauran hanyoyin ba har zuwa bukatun, don haka madubi sarrafa madaidaicin kyawon tsayuwa ne har yanzu yafi inji polishing.
