CNC lathe ndi chida cholondola kwambiri, chapamwamba kwambiri chodziwikiratu. Kugwiritsa ntchito CNC lathe kumatha kupititsa patsogolo kukonza bwino ndikupanga phindu lochulukirapo. Kutuluka kwa CNC lathe kumathandizira mabizinesi kuti achotse ukadaulo wakumbuyo. Ukadaulo waukadaulo wa CNC lathe ndi wofanana, koma popeza lathe ya CNC ndi kugunda kwanthawi imodzi ndikusintha kosalekeza kokhazikika kumamaliza njira zonse zokhotakhota, zotsatirazi ziyenera kutsatiridwa.
Kusankha koyenera kwa kuchuluka kwa kudula
Kwa kudula zitsulo zamphamvu kwambiri, zinthu zomwe ziyenera kukonzedwa, zida zodulira, ndi mikhalidwe yodulira ndi zinthu zazikulu zitatu. Izi zimatsimikizira nthawi ya makina, moyo wa zida ndi mtundu wa makina. Njira yoyendetsera ndalama komanso yothandiza iyenera kukhala kusankha koyenera kwa zinthu zodula.
Zinthu zitatu za kudula mikhalidwe: kudula liwiro, kuchuluka kwa chakudya ndi kuya kwa kudula kumayambitsa kuwonongeka kwa chida. Ndi kuwonjezeka kwa liwiro la kudula, kutentha kwa nsonga ya chida kudzawuka, zomwe zidzapangitse kuvala kwa makina, mankhwala ndi kutentha. Kuthamanga kwachulukira ndi 20%, moyo wa zida udzachepetsedwa ndi 1/2.
Kugwirizana pakati pa chakudya chamagulu ndi kuvala kumbuyo kwa zida kumachitika mkati mwazochepa kwambiri. Komabe, mlingo wa chakudya ndi waukulu, kutentha kwa kudula kumakwera, ndipo kuvala kumbuyo kumakhala kwakukulu. Zili ndi zotsatira zochepa pa chida kusiyana ndi kudula liwiro. Ngakhale zotsatira za kuya kwa odulidwa pa chida si zazikulu monga kudula liwiro ndi mlingo wa chakudya, pamene kudula ndi kuya pang'ono odulidwa, zinthu kuti kudula adzabala wosanjikiza woumitsa, zomwe zidzakhudzanso moyo wa chida.
Wogwiritsa ntchitoyo ayenera kusankha liwiro lodula kuti agwiritse ntchito molingana ndi zinthu zomwe zimayenera kukonzedwa, kuuma, kudula boma, mtundu wazinthu, kuchuluka kwa chakudya, kudula kuya, etc.
Kusankhidwa kwa zinthu zoyenera kwambiri zogwirira ntchito kumasankhidwa pazifukwa izi. Kuvala kokhazikika, kokhazikika mpaka kumapeto kwa moyo ndiye mkhalidwe wabwino.
Komabe, mu ntchito yeniyeni, kusankha kwa moyo wa chida kumakhudzana ndi kuvala kwa zida, kusintha kwa kukula, khalidwe lapamwamba, phokoso locheka, kutentha kutentha, ndi zina zotero. Pazinthu zovuta kumakina monga zitsulo zosapanga dzimbiri ndi ma aloyi osatentha, zoziziritsa kuziziritsa zitha kugwiritsidwa ntchito kapena m'mphepete mwachitsulo chokhazikika chitha kugwiritsidwa ntchito.
Momwe mungadziwire zinthu zitatu za kudula processing
Momwe mungasankhire bwino zinthu zitatuzi ndizomwe zili muzitsulo zodulira mfundo. Metal processing WeChat yatulutsa mfundo zazikulu, ndi mfundo zoyambira posankha zinthu zitatu izi:
(1) Kudula liwiro (liwiro la mzere, liwiro lozungulira) V (m/min)
Kuti musankhe masinthidwe a spindle pamphindi, choyamba muyenera kudziwa kuchuluka kwa liwiro la mzere V. Kusankha V: zimatengera zida zakuthupi, zida zogwirira ntchito, zinthu zogwirira ntchito, etc.
Zida zothandizira:
Carbide, V angapezeke apamwamba, zambiri kuposa 100 m/mphindi, zambiri kupereka magawo luso pogula masamba:
Momwe liwiro la mzere lingasankhidwe pokonza zinthu zilizonse. Chitsulo chothamanga kwambiri: V ikhoza kukhala yotsika, nthawi zambiri osapitirira 70 m / min, ndipo nthawi zambiri imakhala yosakwana 20-30 m / min.
Zida zogwirira ntchito:
Kuuma kwakukulu, otsika V; kuponyedwa chitsulo, otsika V, 70 ~ 80 m/mphindi pamene chida ndi simenti carbide; chitsulo chochepa cha carbon, V pamwamba pa 100 m / min, zitsulo zopanda chitsulo, V apamwamba (100 ~ 200 m / min). Pazitsulo zolimba ndi zitsulo zosapanga dzimbiri, V iyenera kukhala yotsika.
Kukonzekera:
Kwa makina ovuta, V ayenera kukhala otsika; kwa makina abwino, V ayenera kukhala apamwamba. Dongosolo lolimba la chida cha makina, chogwirira ntchito, ndi chida ndilabwino, ndipo V iyenera kukhala yotsika. Ngati S ntchito mu pulogalamu NC ndi chiwerengero cha zozungulira spindle pamphindi, ndiye S ayenera kuwerengedwa molingana ndi awiri a workpiece ndi kudula mzere liwiro V: S (ozungulira spindle pa mphindi) = V (kudula mzere liwiro) * 1000 / (3.1416 * workpiece Diameter) Ngati pulogalamu ya NC imagwiritsa ntchito liwiro lokhazikika, ndiye kuti S imatha kugwiritsa ntchito mwachindunji liwiro la V (m / min)
(2) Kuchuluka kwa chakudya (kudula)
F makamaka zimadalira workpiece pamwamba roughness amafuna. Pomaliza makina, chofunika pamwamba ndi mkulu, ndi kudula ndalama ayenera kukhala ochepa: 0.06 ~ 0.12mm / spindle pa kusintha. Pamene roughing, izo m'pofunika kukhala wamkulu. Zimadalira makamaka mphamvu ya chida. Nthawi zambiri, ndi oposa 0.3. Pamene mbali yaikulu ya mpumulo wa chidayo ndi yaikulu, mphamvu ya chida ndi yosauka, ndipo kuchuluka kwa kudula sikuyenera kukhala kwakukulu. Kuonjezera apo, mphamvu ya chida cha makina ndi kukhwima kwa workpiece ndi chida ziyenera kuganiziridwanso. Pulogalamu ya NC imagwiritsa ntchito magawo awiri a mlingo wa chakudya: mm/min, mm/spindle per revolution, unit yomwe imagwiritsidwa ntchito pamwambayi ndi mm/spindle per revolution, ngati mm/min ikagwiritsidwa ntchito, formula ikhoza kusinthidwa: feed per miniti = per Revolving. kuchuluka kwa chakudya* kusintha kwa spindle pamphindi
(3) Kucheka kuya (kucheka kuya)
Pomaliza makina, nthawi zambiri amakhala ochepera 0.5 (mtengo wa radius). Pa makina akhakula, zimatengera mikhalidwe ya workpiece, kudula chida ndi makina chida. Nthawi zambiri, lathes ang'onoang'ono (pazipita Machining awiri m'munsimu 400mm) kutembenuza zitsulo No. 45 mu chikhalidwe normalized, ndi kuya kwa mpeni kudula mu malangizo radial zambiri si upambana 5mm. Komanso, tisaiwale kuti ngati spindle liwiro la lathe utenga wamba pafupipafupi kutembenuka liwiro lamulo, ndiye pamene liwiro spindle pamphindi ndi otsika kwambiri (zosakwana 100 ~ 200 rpm), linanena bungwe mphamvu ya galimoto. kuchepetsedwa kwambiri. Kuzama ndi kuchuluka kwa chakudya kumatha kupezeka kochepa kwambiri.
Kusankha koyenera kwa mipeni
1. Pamene kutembenuka kwaukali, ndikofunikira kusankha chida chokhala ndi mphamvu zambiri komanso kukhazikika bwino, kuti mukwaniritse zofunikira za kudula kwakukulu ndi chakudya chachikulu panthawi yokhotakhota.
2. Mukamaliza galimotoyo, m'pofunika kusankha chida cholondola kwambiri komanso chokhazikika bwino kuti mutsimikizire zofunikira za makina olondola.
3. Pofuna kuchepetsa nthawi yosinthira chida ndikuthandizira kukhazikitsa zida, zida zomangira makina ndi makina opangira makina ziyenera kugwiritsidwa ntchito momwe zingathere.
Zida za Xinfa CNC zili ndi zabwino kwambiri komanso zolimba, kuti mumve zambiri, chonde onani: https://www.xinfatools.com/cnc-tools/
Kusankha koyenera kwa zosintha
1. Yesetsani kugwiritsa ntchito zida zanthawi zonse kuti muchepetse zida, ndipo pewani kugwiritsa ntchito zida zapadera;
2. Datum yoyika magawo imagwirizana kuti achepetse cholakwika chapamalo.
Dziwani njira yopangira
Njira yoyendetsera imatanthawuza kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake ndi njira ya chida chokhudzana ndi gawo panthawi ya makina a CNC.
1. Iyenera kuwonetsetsa kuti makinawo ali olondola komanso ovuta kwambiri;
2. Njira yogwiritsira ntchito iyenera kufupikitsidwa momwe mungathere kuti muchepetse nthawi yoyenda yopanda ntchito ya chida.
Mgwirizano wapakati pa processing njira ndi processing allowance
Pakali pano, malinga ndi kuti lathe ya CNC sinagwiritsidwebe ntchito kwambiri, nthawi zambiri ndalama zochulukirapo zomwe zilibe kanthu, makamaka ndalama zomwe zimakhala ndi zigawo zolimba za khungu, ziyenera kukonzedwa pa lathe wamba. Ngati ikuyenera kukonzedwa ndi CNC lathe, chidwi chiyenera kuperekedwa ku dongosolo losinthika la pulogalamuyo.
Zokonza zoikamo
Pakadali pano, kulumikizana pakati pa hydraulic chuck ndi hydraulic clamping cylinder kumazindikirika ndi ndodo yokoka. Mfundo zazikuluzikulu za hydraulic chuck clamping ndi izi: choyamba, gwiritsani ntchito wrench kuchotsa nati pa silinda ya hydraulic, chotsani chubu chokoka, ndikuchikoka kuchokera kumapeto kwa shaft yaikulu, ndiyeno Gwiritsani ntchito wrench kuchotsa. zomangira chuck kuchotsa chuck.
