Mu CNC Machining, chida chamoyo chimatanthawuza nthawi yomwe chida chodulira chimadula chojambulacho panthawi yonseyi kuyambira koyambirira kwa makina kupita pachidutswa chazida, kapena kutalika kwa malo opangira ntchito panthawi yodula.
1. Kodi chida chazida chitha kusintha?
Moyo wazida ndi mphindi 15-20 zokha, kodi chida chamoyo chingakonzedwe bwino? Zachidziwikire, moyo wazida ukhoza kusinthidwa mosavuta, koma pokhapokha ngati mungapereke liwiro la mzere. Kutsika kwa liwiro la mzere, kumawonekeranso kuwonjezeka kwazida zamagetsi (koma liwiro lotsika kwambiri limapangitsa kugwedera pakukonza, komwe kumachepetsa moyo wazida).
2. Kodi pali chilichonse chofunikira pakusintha chida chazida?
Pogwiritsa ntchito mtengo wogwiritsira ntchito, kuchuluka kwa mtengo wazida ndizochepa kwambiri. Kuthamanga kwazitsulo kumachepa, ngakhale chida chidawonjezeka, koma nthawi yogwiritsira ntchito imagwiranso ntchito, kuchuluka kwa zida zogwiritsidwa ntchito ndi chida sikuyenera kukulirakulira, koma mtengo wamagetsi ukwera.
Chomwe chikuyenera kumvedwa molondola ndikuti ndizomveka kuwonjezera kuchuluka kwa magwiridwe antchito momwe zingathere poonetsetsa kuti chida chikugwira ntchito momwe zingathere.
3. Zinthu zomwe zimakhudza moyo wazida
1. Liwiro la mzere
Kuthamanga kwazitali kumakhudza kwambiri chida chogwiritsa ntchito. Ngati kuthamanga kwazitali ndikokwera kuposa 20% ya ma velocity ofotokozedwayo, moyo wazida udzachepetsedwa mpaka 1/2 wazoyambirira; ngati yawonjezeka mpaka 50%, chida chogwiritsa ntchito chidzangokhala 1/5 yoyambirira. Kuti muwonjezere moyo wa chida, ndikofunikira kudziwa zakuthupi, momwe ntchito iliyonse iyenera kukonzedwa, komanso kuthamanga kwa chida chosankhidwa. Zida zodulira kampani iliyonse zimakhala ndi ma liwiro osiyana. Mutha kusaka koyambirira kuchokera pazitsanzo zomwe kampaniyo ikupereka, kenako ndikuzisintha malinga ndi momwe zinthu zilili pokonzekera kuti zikwaniritse bwino. Zambiri za liwiro la mzere panthawi yovuta komanso kumaliza sizigwirizana. Roughing makamaka imayang'ana kuchotsa malire, ndipo liwiro la mzere liyenera kukhala lotsika; pomaliza, cholinga chachikulu ndikuwonetsetsa kuti zowoneka molondola komanso zovuta, ndipo liwiro la mzere liyenera kukhala lokwera.
2. Kuzama kwa kudula
Mphamvu yakuchepetsa kuzama pazida zamagetsi siyabwino kwambiri ngati kuthamanga kwakanthawi. Mtundu uliwonse wamakina uli ndi malo ocheperako ochepa. Pakati pa makina okhwima, kuya kwa kudula kuyenera kuwonjezeredwa momwe zingathere kuti zitsimikizire kuchuluka kwachangu kwa malire; mukamaliza, kuya kwa kudula kumayenera kukhala kochepera momwe mungathere kuti muwonetsetse kulondola kwake komanso mawonekedwe ake. Koma akuya kudula sangapitirire kudula osiyanasiyana masamu. Ngati kudula kochuluka ndikokulirapo, chidacho sichingathe kupirira mphamvu yocheka, zomwe zimapangitsa kuti chida chikucheke; ngati kudula kocheperako kuli kocheperako, chidacho chimangokanda ndikufinya pamwamba pa workpiece, ndikupangitsa kuvala kwakukulu pambali pake, potero kumachepetsa moyo wazida.
3. Dyetsani
Poyerekeza ndi liwiro la mzere ndi kuzama kwa kudula, chakudya chimakhudza kwambiri chida chogwiritsa ntchito, koma chimakhudza kwambiri mawonekedwe apamwamba a chopangira. Pakati pa makina okhwima, kuwonjezera chakudya kumatha kukulitsa kuchotsedwa kwa malire; Mukamaliza, kuchepetsa chakudya kumatha kukulitsa kukhathamira kwa malo ogwirira ntchito. Ngati kukalipa kulola, chakudya chitha kukulitsidwa momwe zingathere kukonza magwiridwe antchito.
4. Kugwedera
Kuphatikiza pazinthu zitatu zazikulu zodulira, kugwedera ndichinthu chomwe chimakhudza kwambiri moyo wazida. Pali zifukwa zambiri zogwedezeka, kuphatikiza zida zama makina, kukhazikika kwa zida, magwiridwe antchito, magawo odulira, chida geometry, chida cha arc radius, tsamba lopumulira tsamba, chida chophatikizira, ndi zina zambiri, koma chifukwa chachikulu ndichakuti dongosololi ndi osakhwima mokwanira kuti athe kulimbana ndi mphamvu yakuchepetsa pakukonzekera imapangitsa kugwedezeka kwanthawi zonse kwa chida pantchitoyo pokonza. Kuthetsa kapena kuchepetsa kugwedezeka kuyenera kuganiziridwa mozama. Kugwedezeka kwa chida pamalo opangira ntchito kumatha kumveka ngati kugogoda kosalekeza pakati pa chida ndi chojambuliracho, m'malo modula mwachizolowezi, komwe kumapangitsa ming'alu ndi zingwe zazing'ono kumapeto kwa chidacho, ndipo ming'alu iyi ndi kudulira kuyambitsa mphamvu yakuchulukirachulukira. Chachikulu, kugwedera kumakulitsanso, iwonso, ming'alu ndi ming'alu ikuwonjezeka, ndipo moyo wazida wafupika kwambiri.
5. Zinthu zakuthambo
Pomwe workpiece ikukonzedwa, timangoganizira zofunikira pa workpiece, zofunikira pakuthandizira kutentha, komanso ngati kusokonekera kwake kwasokonekera. Mwachitsanzo, masamba opangira zida zachitsulo ndi omwe amapangira chitsulo chosungunula, ndipo masamba omwe ali ndi kuwuma kwa HB215 ndi HRC62 siofanana ayi; masamba a kukonza kwapakatikati ndi kukonza mosalekeza sizofanana. Zitsulo zazitsulo zimagwiritsidwa ntchito pokonza magawo azitsulo, masamba oponyera amagwiritsidwa ntchito pokonza ma castings, masamba a CBN amagwiritsidwa ntchito pokonza chitsulo cholimba, ndi zina zambiri. Pazinthu zomwezo, ngati ndizopangika mosalekeza, tsamba logwiritsa ntchito lalitali liyenera kugwiritsidwa ntchito, lomwe lingapangitse liwiro la chopangira, kuchepetsa kuvala kwa chida, ndikuchepetsa nthawi yakusinthira; Ngati mukusintha mosadukiza, gwiritsani ntchito tsamba lolimba. Ikhoza kuchepetsa kuvala kosazolowereka monga kudulira ndikuwonjezera moyo wantchitoyo.
6. Chiwerengero cha tsamba lomwe amagwiritsidwa ntchito
Kutentha kwakukulu kumapangidwa panthawi yogwiritsira ntchito chida, chomwe chimakulitsa kwambiri kutentha kwa tsamba. Ngati sichingakonzedwe kapena kuzirala ndi madzi ozizira, kutentha kwake kumachepa. Chifukwa chake, tsambalo nthawi zonse limakhala lotentha kwambiri, kotero kuti tsambalo likukulirakulira ndikulimbana ndi kutentha, ndikupangitsa ming'alu yaying'ono m'mitsamba. Tsamba likakonzedwa ndi m'mphepete mwake, chida chazinthu chimakhala chachilendo; koma kugwiritsa ntchito tsambalo kumakulirakulira, kung'ambikaku kudzafika ku masamba ena, zomwe zimapangitsa kuchepa kwa moyo wa masamba ena.
