Hakowa:Hakowa shine tsarin ƙirƙirar ramuka a cikin kayan aiki ta amfani da kayan aikin yankan juyawa. Ana amfani da shi a aikace-aikace daban-daban, gami da samar da tubalan injin, abubuwan da ke cikin sararin samaniya, da shingen lantarki.
Injin Cire Lantarki (EDM):EDM yana amfani da fitar da wutar lantarki don kawar da kayan aiki daga kayan aiki, yana ba da damar samar da siffofi masu mahimmanci da siffofi tare da madaidaici. Ana amfani da ita sosai wajen kera gyare-gyaren allura, mutuwar-simintin, da abubuwan haɗin sararin samaniya.
A aikace aikace-aikace na madubi inji a cikin CNC machining ne daban-daban. Ya haɗa da samar da abubuwa don masana'antu daban-daban kamar sararin samaniya, motoci, na'urorin likitanci, na'urorin lantarki, da kayan masarufi. Ana amfani da waɗannan matakai don ƙirƙirar nau'ikan sassa daban-daban, daga sassauƙan raƙuman ruwa da sanduna zuwa hadaddun abubuwan haɗin sararin samaniya da ƙwararrun likitanci.
Gudanar da madubi yana nufin gaskiyar cewa saman da aka sarrafa zai iya nuna hoton kamar madubi. Wannan matakin ya sami kyakkyawan ingancin farfajiyarmachining sassa. Ayyukan madubi ba zai iya haifar da bayyanar inganci kawai don samfurin ba amma har ma yana rage tasirin sakamako kuma ya tsawaita rayuwar gajiyar aikin. Yana da matukar mahimmanci a yawancin taro da tsarin rufewa. The polishing madubi sarrafa fasaha da yafi amfani don rage surface roughness na workpiece. Lokacin da aka zaɓi hanyar polishing don aikin aikin ƙarfe, ana iya zaɓar hanyoyin daban-daban bisa ga buƙatu daban-daban. Wadannan su ne hanyoyin gama gari da yawa na fasahar sarrafa madubi.
1. Gyaran injina wata hanya ce ta gogewa wacce ta haɗa da yankewa da ɓata saman abu don cire lahani da samun ƙasa mai santsi. Wannan hanyar yawanci ta ƙunshi amfani da kayan aiki kamar ɗigon dutsen mai, ƙafafun ulu, da takarda yashi don aiki da hannu. Don sassa na musamman kamar saman jikin jujjuyawar, ana iya amfani da kayan aikin taimako kamar na'urorin juyawa. Lokacin da ake buƙatar ingancin saman ƙasa, za a iya amfani da hanyoyin niƙa da goge-goge. Superfinishing nika da polishing ya ƙunshi yin amfani da musamman abrasives a cikin wani ruwa dauke da abrasives, manne a kan workpiece domin high-gudun Rotary motsi. Amfani da wannan dabara, a surface roughness na Ra0.008μm za a iya cimma, sa shi mafi girma a cikin daban-daban polishing hanyoyin. Ana amfani da wannan hanyar sau da yawa a cikin ƙirar ruwan tabarau na gani.
2. Chemical polishing wani tsari ne da ake amfani da shi don narkar da ɓangarorin da ba a iya gani ba na wani abu a cikin matsakaicin sinadari, yana barin sassan da ba a taɓa su ba kuma yana haifar da ƙasa mai santsi. Wannan hanyar ba ta buƙatar kayan aiki masu rikitarwa kuma tana da ikon goge kayan aiki tare da hadaddun sifofi yayin kasancewa mai inganci don goge kayan aiki da yawa a lokaci guda. Babban ƙalubale a cikin gogewar sinadarai shine shirya slurry mai gogewa. Yawanci, ƙarancin saman da aka samu ta hanyar goge sinadarai yana kusa da mitoci goma.
3. Ainihin ka'idar electrolytic polishing yayi kama da na polishing sinadaran. Ya ƙunshi zaɓin narkar da ƙananan sassa masu fitowa na saman kayan don sanya shi santsi. Ba kamar sinadarai polishing, electrolytic polishing iya kawar da sakamakon cathodic dauki da kuma samar da mafi kyau sakamako. Tsarin polishing electrochemical ya ƙunshi matakai guda biyu: (1) matakin macroscopic, inda samfurin narkar da ke yaduwa a cikin electrolyte, yana rage girman yanayin yanayin, kuma Ra ya zama mafi girma fiye da 1μm; da (2) micropolishing, wanda a cikinsa ya baje ko'ina, anode ya zama polarized, kuma hasken saman yana ƙaruwa, tare da Ra kasancewa kasa da 1μm.
4. Ultrasonic polishing ya shafi ajiye workpiece a cikin wani abrasive dakatar da kuma subjecting shi zuwa ultrasonic taguwar ruwa. Raƙuman ruwa suna haifar da abrasive don niƙa da goge samanal'ada cnc sassa. Ultrasonic machining exerts wani karamin macroscopic karfi, wanda ya hana workpiece nakasawa, amma yana iya zama kalubale ga ƙirƙira da shigar da zama dole kayan aiki. Ana iya haɗa mashin ɗin ultrasonic tare da hanyoyin sinadarai ko na lantarki. Aiwatar da jijjiga ultrasonic don motsa maganin yana taimakawa wajen kawar da samfuran narkar da su daga farfajiyar workpiece. A cavitation sakamako na ultrasonic tãguwar ruwa a cikin taya kuma taimaka hana lalata tsari da kuma facilitates surface haskakawa.
5. Fluid polishing yana amfani da ruwa mai gudu mai sauri da kuma barbashi abrasive don wanke saman wani workpiece don gogewa. Hanyoyin gama gari sun haɗa da jetting abrasive, jetting na ruwa, da niƙa mai ƙarfi. Hydrodynamic nika ne hydraulically kore, haifar da ruwa matsakaici dauke da abrasive barbashi don matsawa da baya da kuma fitar a fadin workpiece surface a high gudun. Matsakaici ya ƙunshi abubuwa na musamman (kamar abubuwa masu kama da polymer) tare da kwarara mai kyau a ƙananan matsi, gauraye da abrasives irin su silicon carbide powders.
6. Mirror polishing, kuma aka sani da mirroring, Magnetic nika, da kuma polishing, ya shafi yin amfani da Magnetic abrasives don ƙirƙirar abrasive goge da taimakon Magnetic filayen ga nika da sarrafa workpieces. Wannan hanyar tana ba da ingantaccen sarrafawa, inganci mai kyau, sauƙin sarrafa yanayin sarrafawa, da yanayin aiki mai kyau.
Lokacin da aka yi amfani da abrasives masu dacewa, ƙazantaccen saman zai iya kaiwa Ra 0.1μm. Yana da mahimmanci a lura cewa a cikin sarrafa gyare-gyaren filastik, manufar polishing ya bambanta da buƙatun gyaran fuska a wasu masana'antu. Musamman, ya kamata a yi la'akari da gyaran gyare-gyare a matsayin kammalawar madubi, wanda ke sanya babban buƙatu ba kawai akan tsarin gogewa da kansa ba har ma a kan shimfidar ƙasa, santsi, da daidaiton geometric.
Sabanin haka, gyaran fuska gabaɗaya yana buƙatar ƙasa mai haske kawai. Ma'aunin sarrafa madubi ya kasu kashi huɗu: AO = Ra 0.008μm, A1=Ra 0.016μm, A3=Ra 0.032μm, A4=Ra 0.063μm. Tunda hanyoyin kamar polishing electrolytic, polishing na ruwa, da sauransu suna gwagwarmaya don sarrafa daidaitattun daidaiton lissafi naCNC niƙa sassa, da kuma saman ingancin polishing sinadarai, ultrasonic polishing, Magnetic nika da polishing, da makamantansu hanyoyin bazai cika buƙatun ba, aikin madubi na madaidaicin gyare-gyaren ya dogara ne akan gogewar injiniya.
