Yadda za a rage fitar da kayan aiki a cikiCNCniƙa?
Kuskuren da ke haifar da radial runout na kayan aiki kai tsaye yana rinjayar ƙananan kuskuren siffar da daidaitattun siffar geometric na kayan aikin da za a iya samu ta hanyar kayan aikin injin a ƙarƙashin kyakkyawan yanayin aiki. Mafi girma da radial runout na kayan aiki, da mafi m yanayin aiki na kayan aiki, da kuma mafi rinjayar da aiki sakamako.
▌ Abubuwan da ke haifar da zubar da jini
1. Tasirin radial runout na spindle kanta
Babban dalilai na kuskuren radial runout na spindle shine kuskuren coaxiality na kowane jarida na spindle, kurakurai daban-daban na ɗaukar kanta, kuskuren coaxiality tsakanin bearings, karkatar da igiya, da dai sauransu, da tasirin su akan daidaitattun juyawa na radial sandal ɗin ya bambanta da hanyar sarrafawa.
2. Tasirin rashin daidaituwa tsakanin cibiyar kayan aiki da cibiyar juyawa na spindle
Lokacin da aka shigar da kayan aiki a kan sandar, idan tsakiyar kayan aiki da cibiyar juyawa na spindle ba daidai ba ne, radial runout na kayan aiki ba makawa zai faru.
Abubuwan da ke tasiri na musamman sune: daidaitawar kayan aiki da chuck, ko hanyar ɗaukar kayan aiki daidai ne, da ingancin kayan aikin kanta.
3. Tasirin takamaiman fasahar sarrafawa
Radial runout na kayan aiki a lokacin sarrafawa shine yafi saboda ƙarfin yanke radial yana ƙara haɓaka radial runout. Ƙarfin yankan radial shine ɓangaren radial na jimlar ƙarfin yanke. Zai sa kayan aikin ya lanƙwasa da lalacewa kuma ya haifar da girgiza yayin aiki, kuma shine babban ƙarfin bangaren da ke shafar ingancin sarrafa kayan aiki. An fi shafa shi da abubuwa kamar yankan adadin, kayan aiki da kayan aiki, kayan aikin lissafi na kayan aiki, hanyar lubrication da hanyar sarrafawa.
▌ Hanyoyin rage radial runout
Radial runout na kayan aiki a lokacin sarrafawa shine yafi saboda ƙarfin yanke radial yana ƙara haɓaka radial runout. Sabili da haka, rage karfin yankan radial shine muhimmiyar ka'ida don rage radial runout. Ana iya amfani da hanyoyi masu zuwa don rage radial runout:
1. Yi amfani da kayan aiki masu kaifi
Zaɓi babban kusurwar rake kayan aiki don sanya kayan aikin ya fi ƙarfin don rage yanke ƙarfi da girgiza.
Zaɓi babban kusurwar baya na kayan aiki don rage juzu'i tsakanin babban fuskar kayan aiki da madogarar dawo da na'ura mai ƙarfi na shimfidar kayan aiki, don haka rage girgiza. Duk da haka, rake kwana da baya kwana na kayan aiki ba za a iya zaba da yawa girma, in ba haka ba zai kai ga rashin ƙarfi da zafi dissipation yankin na kayan aiki.
Zai iya zama ƙarami a lokacin aiki mai mahimmanci, amma a cikin aiki mai kyau, don rage radial runout na kayan aiki, ya kamata ya zama mafi girma don yin kayan aiki mai mahimmanci.
2. Yi amfani da kayan aiki masu ƙarfi
Na farko, ana iya ƙara diamita na mashaya kayan aiki. A karkashin irin wannan ƙarfin yankan radial, diamita na kayan aiki yana ƙaruwa da 20%, kuma za a iya rage radial runout na kayan aiki da 50%.
Na biyu, za a iya rage tsawon tsawo na kayan aiki. Mafi girman tsayin tsayin kayan aiki, mafi girman nakasar kayan aiki yayin aiki. Kayan aiki yana cikin canji koyaushe yayin aiki, kuma radial runout na kayan aikin zai canza ci gaba, wanda zai haifar da wani m surface na workpiece. Hakazalika, idan an rage tsawon tsawo na kayan aiki da kashi 20%, za a kuma rage radial runout na kayan aiki da 50%.
3. Gaban yankan kayan aiki ya kamata ya zama santsi
A lokacin aiki, ƙwanƙwasa mai laushi na gaba zai iya rage raguwa na kwakwalwan kwamfuta a kan kayan aiki, kuma yana iya rage ƙarfin yankewa a kan kayan aiki, ta haka yana rage radial runout na kayan aiki.
4. Tsaftace madaurin dunƙule da yanke
Taper da chuck ya kamata su kasance masu tsabta, kuma kada a sami ƙura da tarkace da aka haifar yayin sarrafa kayan aiki.
Lokacin zabar kayan aiki, gwada amfani da kayan aiki tare da ɗan gajeren tsawo. Lokacin yankan, ƙarfin ya kamata ya zama mai ma'ana kuma ya zama iri ɗaya, ba babba ko ƙarami ba.
5. Zaɓin madaidaicin yanke zurfin yanke
Idan zurfin yankan ya yi ƙanƙara, mashin ɗin zai zamewa, wanda zai sa kayan aiki su ci gaba da canza radial runout a lokacin machining, yin injin da aka yi amfani da shi. Lokacin da zurfin yankan ya yi girma sosai, ƙarfin yanke zai karu daidai da haka, yana haifar da babban lahani na kayan aiki. Ƙara radial runout na kayan aiki a lokacin machining zai kuma sa na'ura m surface m.
6. Yi amfani da jujjuyawar niƙa yayin kammalawa
A lokacin milling gaba, da rata matsayi tsakanin gubar dunƙule da goro canje-canje, wanda zai haifar da m ciyar da worktable, haifar da tasiri da kuma vibration, shafi rayuwar inji kayan aiki da kayan aiki da machining surface roughness na workpiece.
Lokacin amfani da milling na baya, yanke kauri yana canzawa daga ƙarami zuwa babba, nauyin kayan aiki kuma yana canzawa daga ƙarami zuwa babba, kuma kayan aikin yana da kwanciyar hankali yayin injin. Lura cewa ana amfani da wannan kawai lokacin kammalawa. Don sarrafa injina, yakamata a yi amfani da niƙa na gaba saboda niƙa na gaba yana da babban aiki kuma ana iya tabbatar da rayuwar kayan aiki.
7. Haƙiƙa na amfani da yankan ruwa
Amfani mai ma'ana na yanke ruwa mai ruwa mai ruwa tare da sanyaya kamar yadda babban aikin ba shi da ɗan tasiri akan yanke ƙarfi. Yanke mai, wanda galibi yana aiki azaman mai mai, yana iya rage yanke ƙarfi sosai.
Aiki ya tabbatar da cewa idan dai an tabbatar da samar da daidaito da daidaito na kowane bangare na kayan aikin injin kuma an zaɓi matakai masu ma'ana da kayan aiki, ana iya rage tasirin tasirin radial na kayan aiki akan daidaiton mashin ɗin na kayan aikin.
