Milling abun yanka kayan yau da kullum

Menene abin yankan niƙa?

Daga ra'ayi na ƙwararru, abin yankan niƙa shine kayan aikin yankan da ake amfani da shi don niƙa. Yana iya juyawa kuma yana da hakora ɗaya ko fiye. Yayin aikin niƙa, kowane haƙori yana yanke izinin aiki na ɗan lokaci. An yafi amfani da machining jiragen sama, matakai, tsagi, kafa saman da yankan workpieces a kan niƙa inji. An kafa ƙasa ƴaƴan ƴan ƙasa a gefen gefe don samar da kusurwar taimako, kuma rayuwarta tana da girma saboda madaidaicin kusurwa. Bayan farar niƙa abun yanka yana da nau'i uku: madaidaiciyar layi, lanƙwasa da layi mai ninka. Ana amfani da baya na layi akai-akai don ƙayyadaddun kayan aikin gamawa masu kyau. Lanƙwasa da murƙushewa suna da ingantacciyar ƙarfin haƙora kuma suna iya jure nauyi yankan kaya, kuma galibi ana amfani da su don masu yankan haƙori.

Menene gama gari masu yankan niƙa?

Cylindrical milling cutter: Ana amfani da shi don sarrafa jiragen sama akan injunan niƙa a kwance. Ana rarraba haƙoran akan kewayen abin yankan niƙa kuma an raba su zuwa madaidaiciyar hakora da hakora masu karkace daidai da siffar haƙori. Dangane da adadin hakora, akwai nau'ikan hakora iri biyu da lallausan hakora. Karkashe hakori m-hakora milling abun yanka yana da ƴan hakora, high hakori ƙarfi, babban guntu sarari, dace da m machining; mai yankan niƙa mai kyau-haƙori ya dace da gamawa;

Abin yankan fuska: ana amfani da injin niƙa a tsaye, injin niƙa fuska ko injunan niƙa. Ƙarshen fuskokin jirgin da kewaye suna da hakora da ƙananan hakora da hakora masu kyau. Tsarin yana da nau'ikan guda uku: nau'in alaƙa, saka nau'in da nau'in masu ma'ana;

Ƙarshen niƙa: ana amfani da shi don injin ramuka da saman matakai. Hakora suna kan kewaye da fuskokin ƙarshe. Ba za a iya ciyar da su a cikin hanyar axial yayin aiki ba. Lokacin da injin ƙarshen yana da haƙori na ƙarshe yana wucewa ta tsakiya, ana iya ciyar da shi axially;

Mai yankan niƙa mai gefe uku: ana amfani da shi don injin ramuka daban-daban da fuskokin mataki tare da hakora a bangarorin biyu da kewaye;

Abun yankan kusurwa: ana amfani da shi don niƙa tsagi a kusurwa, duka masu yankan kusurwa guda ɗaya da na kusurwa biyu;

Saw ruwa niƙa abun yanka: yi amfani da injin zurfin ragi da yanke workpieces tare da ƙarin hakora a kan kewaye. Domin rage gogayya kwana na abun yanka, akwai 15'~ 1° sakandare raguwa a bangarorin biyu. Bugu da kari, akwai keyway niƙa yankan, dovetail nika yankan, T-slot niƙa yankan da daban-daban forming sassa.

Menene abubuwan da ake buƙata don kayan aikin masana'anta na sashin yankan mai yankan milling?

Abubuwan gama gari don masana'antar injin niƙa sun haɗa da ƙarfe na kayan aiki mai sauri, gami da ƙarfi irin su tungsten-cobalt da tushen gami mai ƙarfi na titanium-cobalt. Tabbas, akwai wasu kayan ƙarfe na musamman waɗanda kuma za a iya amfani da su don yin yankan niƙa. Yawancin lokaci, waɗannan kayan ƙarfe suna da kaddarorin masu zuwa:

1) Kyakkyawan aiki na tsari: ƙirƙira, sarrafawa da kaifi suna da sauƙin sauƙi;

2) Babban ƙarfi da juriya: A zafin jiki na al'ada, sashin yanke dole ne ya sami isasshen ƙarfi don yanke cikin aikin; yana da babban juriya na lalacewa, kayan aiki ba ya sawa kuma yana tsawaita rayuwar sabis;

3) Kyakkyawan juriya mai zafi: kayan aiki zai haifar da zafi mai yawa a lokacin aikin yankan, musamman ma lokacin da saurin yankan ya yi girma, zafin jiki zai yi girma sosai. Sabili da haka, kayan aikin kayan aiki ya kamata su sami juriya mai kyau na zafi, har ma a yanayin zafi. Yana iya kula da babban taurin kuma yana da ikon ci gaba da yankewa. Irin wannan taurin zafin jiki kuma ana kiransa thermosetting ko ja taurin.

4) Ƙarfi mai ƙarfi da ƙarfi mai kyau: A lokacin aikin yankewa, kayan aiki dole ne su ɗauki nauyin tasiri mai yawa, don haka kayan aikin kayan aiki ya kamata su sami ƙarfin ƙarfi, in ba haka ba zai zama sauƙi don karyawa da lalacewa. Tun da abin yankan niƙa yana ƙarƙashin girgiza da girgiza, abin yankan niƙaHakanan yakamata ya kasance yana da tauri mai kyau, ta yadda ba shi da sauƙin guntu da guntuwa.

Me zai faru bayan mai yankan niƙa ya wuce gona da iri?

1. Daga siffar gefen wuka, gefen wuka yana da fari mai haske;

2. Daga siffar guntu, kwakwalwan kwamfuta sun zama m da flake-dimbin yawa, kuma launi na kwakwalwan kwamfuta yana da shunayya da hayaki saboda yawan zafin jiki na kwakwalwan kwamfuta;

3. Tsarin niƙa yana haifar da girgiza mai tsanani da ƙararraki mara kyau;

4. Ƙaƙƙarfan yanayin aikin aiki yana da talauci sosai, kuma saman aikin yana da aibobi masu haske tare da alamun sikila ko ripples;

5. Lokacin niƙa sassan ƙarfe tare da masu yankan niƙa na carbide, babban adadin hazo na wuta yakan tashi;

6. Niƙa sassa na karfe da high-gudun karfe milling cutters, idan an sanyaya da man shafawa, zai haifar da yawa hayaki.

Lokacin da abin yankan niƙa ya ƙare, yakamata a dakatar da shi cikin lokaci don bincika lalacewa na abin yankan niƙa. Idan lalacewa ya yi kadan, za'a iya amfani da yankan gefen don niƙa yankan sannan a sake amfani da shi. Idan lalacewa yayi nauyi, dole ne a kaifi don hana abin yankan niƙa daga wuce gona da iri. Saka
