Tare da ci gaban masana'antu, masana'antar sarrafa karafa kuma tana haɓaka cikin sauri, kuma sabbin kayan aiki da sabbin sabbin abubuwa suna fitowa koyaushe. Koyaya, ingancin sarrafawa da ingancin sarrafa samfuran suna da garanti da haɓakawa. Lokacin zabar madaidaicin ruwan yankan ƙarfe, rage gurɓataccen ƙasa ya zama muhimmiyar hanyar haɗi. Koyaya, zaɓin ruwan yankan ƙarfe don kayan aikin injin iri daban-daban shima yana da wahala a zaɓi.

1. Common yankan ruwa iri ga CNC inji kayan aikin

Domin dacewa da lokuta daban-daban na sarrafawa da bukatun tsari, nau'ikan ruwan yankan karfe suma sun bambanta, wanda galibi ya kasu kashi biyu bisa ga tsarin sinadarai da yanayi, wato yankan ruwa na tushen ruwa da yankan mai.

1. Ruwan yankan ruwa yana nufin ruwan yankan da ake buƙatar a tsoma shi da ruwa a gaba. Anti-tsatsa emulsions, anti-tsatsa man shafawa emulsions, matsananci matsa lamba emulsions da microemulsions duk suna cikin wannan rukuni. Matsayin yankan ruwa na tushen ruwa yawanci shine sanyaya da tsaftacewa, kuma tasirin lubrication ba a bayyane yake ba.

2. Ruwan yankan mai yana nufin ruwan yankan da ba ya buƙatar a tsoma shi da ruwa lokacin amfani da shi. Man ma'adinai mai tsafta, mai mai mai, kayan ƙara mai, mai ma'adinai, mai yankan matsananciyar matsa lamba mara aiki da matsananciyar matsatsin yankan mai duk suna cikin wannan nau'in. Sabanin magudanun ruwa na tushen ruwa, ruwan yankan mai yana da tasirin sa mai a fili, amma suna da ƙarancin sanyaya da damar tsaftacewa.

2, zaɓin yankan ruwa don kayan aikin inji daban-daban

Kayan aikin sarrafawa daban-daban, saboda aikin kayan aiki daban-daban, halayen kayan da suka dace da sarrafawa kuma sun bambanta, don haka ya dace da amfani da nau'ikan yankan ruwa daban-daban.

1. Don kayan aikin da aka yi da kayan ƙarfe mai sauri, a lokacin yankan matsakaici da ƙananan sauri, zafi ba shi da girma, don haka ya dace a yi amfani da ruwa mai yankan mai ko emulsion. A cikin babban saurin yankewa, yin amfani da ruwan yankan ruwa na tushen ruwa zai iya samun sakamako mai kyau na sanyaya saboda yawan zafin zafi. A wannan lokacin, idan aka yi amfani da ruwa mai yanke mai, za a samar da hazo mai yawa, wanda zai gurɓata muhalli kuma cikin sauƙi ya haifar da ƙonewa ga kayan aiki, wanda zai shafi ingancin sarrafawa da kuma rayuwar sabis na kayan aiki. . Bugu da kari, yana da kyau a yi amfani da matsananci matsa lamba aqueous mafita ko matsananci matsa lamba emulsions a lokacin m machining, da matsananci matsa lamba emulsions ko matsa lamba sabon mai sun fi dacewa da kammalawa.

Ƙarfe mai sauri yana amfani da ayyukan yankan matsakaici, kuma saurinsa yana kusan 70m / m. Ƙarfe mai sauri shine ƙarfe na ƙarfe wanda ya ƙunshi abubuwa kamar tungsten da chromium don ƙara taurinsa da juriya; duk da haka, taurinsu da ingancin juriya sun ragu zuwa matakin da ba za a yarda da shi ba saboda yanayin zafi sama da 600 ° C. Duk da haka, ana iya amfani da man yankan ruwa mai narkewa don kiyaye zafin aikinsa ƙasa da 600 ° C.

2. Don kayan aikin carbide da aka yi da siminti, tun da yake sun fi dacewa da zafi na kwatsam, kayan aikin ya kamata a yi zafi da kuma kwantar da su daidai yadda zai yiwu, in ba haka ba yana da sauƙi don haifar da chipping. Sabili da haka, ana amfani da ruwan yankan tushen mai tare da ƙarancin ƙarancin zafin jiki, kuma ana ƙara adadin abubuwan da suka dace na rigakafin sawa. Lokacin yankan cikin babban sauri, fesa kayan aikin tare da babban kwararar ruwan yanka don guje wa dumama mara daidaituwa. Kuma wannan hanya na iya rage yawan zafin jiki yadda ya kamata da kuma rage bayyanar hazo mai.

3. Cast alloys (chromium cobalt tungsten) Waɗannan abubuwan haɗin gwiwa ba su da ƙarfe waɗanda ba na ƙarfe ba dangane da cobalt. Lokacin da zafin jiki ya fi 600 ℃, yana da wuya kuma yana da mafi kyawun juriya fiye da ƙarfe mai sauri. Ana iya amfani da wannan don yanke mai sauri, kuma ana iya amfani da shi don yin amfani da kayan aiki mai wuyar yankewa da yanke ayyukan da ke haifar da yanayin zafi. Abubuwan simintin gyare-gyaren simintin gyare-gyare suna da matukar damuwa ga manyan canje-canjen zafin jiki, kamar tsangwama kwatsam a cikin yanke ayyukan. Sun fi dacewa don ci gaba da ayyukan yankewa kuma suna iya amfani da man yankan mai narkewa.

4. Tun da kayan aikin yumbu da kayan aikin lu'u-lu'u suna da juriya mai girman zafin jiki fiye da simintin carbide, galibi suna amfani da dabarun sarrafa bushewa. Wani lokaci, don guje wa yawan zafin jiki da yawa, ana amfani da ruwan yankan ruwa tare da mafi girman zafin zafin jiki don ci gaba da zub da yankin yankan.

5. Ana amfani da Carbides sosai a cikin masana'antar sarrafa ƙarfe. Yawancin lokaci ana kiran su siminti carbides ko manyan allurai masu ƙarfi. Ana yin su ta hanyar ƙara carbide foda na tungsten, titanium, niobium, da tantalum zuwa ƙirar cobalt da sintering a babban zafin jiki. Canza rabo da nau'in carbides na karfe na iya samar da nau'ikan siminti iri-iri. Ana amfani da carbide da aka yi da siminti saboda har yanzu yana riƙe taurinsa kuma yana juriya a yanayin zafi na 1000°C. Yawancin lokaci ana amfani da su azaman abin sakawa ko yankan kawunan da za'a iya maye gurbinsu. Kowane kai yana da siffa da kusurwa daban. Ana iya sake shigar da shi kuma a adana shi bisa ga buƙatu daban-daban. Wata hanyar masana'anta mai sauƙi ita ce ta rufe Layer na carbide a kan yankan kayan aiki. Hanyar masana'anta ita ce ta rufe kayan aikin carbide na gargajiya ta hanyar ƙaura daga titanium carbide. Shugaban yankan da aka yi ta wannan hanyar yana da juriya mai girma, kuma mai yankan kanta ba ta da sauƙin karya. Ana amfani da kayan aikin Carbide sau da yawa tare da mai yankan ruwa mai narkewa, amma dole ne a zaɓi su a hankali. Wasu abubuwan da ake ƙarawa za su lalata ƙarfen da ke rufe cobalt.

6. Babban ɓangaren kayan aikin yumbu / lu'u-lu'u na kayan aikin katako shine alumina, wanda zai iya kula da taurin su kuma ya sa juriya a yanayin zafi. Duk da haka, kamar yadda aka ambata a sama, abin da ya fi ƙarfin abu, mafi raunin shi ne, wanda ya sa kayan aikin yumbu ba su dace da yanke yankewa ba ko nauyin girgiza da canje-canjen zafin jiki. Lokacin da ake yin injin, zaku iya amfani da man yankan da ba ruwa mai narkewa (man yankan mai) ko kuma ki yi amfani da yankan mai kwata-kwata, ku guji amfani da man yankan mai-ruwa.

7. Kayan aikin yankan mafi wuya shine lu'u-lu'u, amma kuma yana da rauni. Za a iya amfani da lu'u-lu'u a cikin ayyukan sarrafa kayan aikin aluminum, wannan gami yana ƙunshe da ƙwayoyin siliki mai wuya, zai sa kayan aikin carbide da sauri. Hakanan ya dace da niƙa da sarrafa kayan da ba na ƙarfe ba, kamar dutse da siminti. Diamonds za a iya oxidized a high zafin jiki, don haka bai dace da alloys da wuya a aiwatar. Domin yana da wuyar gaske, ana yawan amfani da shi wajen niƙa. Ana iya amfani da man yankan mai ko man yankan mai mai narkewa ko ruwan yankan roba.
