CNC lathe Machining process luso

CNC lathe ndi mtundu wa makina olondola kwambiri komanso ochita bwino kwambiri. Kugwiritsa ntchito lathe ya CNC kumatha kukulitsa luso la makina ndikupanga phindu lochulukirapo. Kutuluka kwa CNC lathe kwapangitsa kuti mabizinesi achotse ukadaulo wakumbuyo. Ukadaulo wa CNC lathe processing poyerekeza ndi lathes wamba. Njira yopangira makina ndi yofanana, koma chifukwa lathe ya CNC imakhala yolimba kamodzi komanso makina okhazikika kuti amalize njira zonse zokhotakhota, zotsatirazi ziyenera kutsatiridwa.

Kusankha koyenera kwa kudula ndalama

Pakuti mkulu-mwachangu zitsulo kudula processing, zinthu kukonzedwa, kudula zida, ndi mikhalidwe kudula ndi zinthu zazikulu zitatu. Izi zimatsimikizira nthawi yokonza, moyo wa chida ndi khalidwe la processing. The chuma ndi ogwira Machining njira ayenera kukhala wololera kusankha zinthu kudula.

Zinthu zitatu zodula: kuthamanga, kuchuluka kwa chakudya ndi kuya kwa kudula kumayambitsa kuwonongeka kwa chida. Ndi kuwonjezeka kwa liwiro la kudula, kutentha kwa nsonga ya chida kudzakwera, zomwe zidzapangitse kuvala kwa makina, mankhwala, ndi kutentha. Kuthamanga kwachulukira ndi 20%, moyo wa zida udzachepetsedwa ndi 1/2.

Chiyanjano pakati pa chikhalidwe cha chakudya ndi kuvala kumbuyo kwa chidacho chimapezeka pamtundu wochepa kwambiri. Komabe, mlingo wa chakudya ndi waukulu, kutentha kwa kudula kumakwera, ndipo kuvala kumbuyo kumakhala kwakukulu. Zili ndi mphamvu zochepa pa chida kusiyana ndi kudula liwiro. Ngakhale chikoka cha kudula kuya pa chida si chachikulu monga kudula liwiro ndi mlingo wa chakudya, pamene kudula pa kuya pang'ono odulidwa, zinthu kudula adzabala wosanjikiza woumitsa, zomwe zidzakhudzanso moyo wa chida. .

Wogwiritsa ntchitoyo ayenera kusankha liwiro lodulira lomwe lingagwiritsidwe ntchito molingana ndi zinthu zomwe zakonzedwa, kuuma, kudula, mtundu wazinthu, kuchuluka kwa chakudya, kuya kwa kudula, etc.

Kusankhidwa kwa zinthu zoyenera kwambiri zogwirira ntchito kumasankhidwa pazifukwa izi. Zovala zokhazikika, zokhazikika komanso moyo wautali ndizoyenera.

Komabe, muzochita zenizeni, kusankha kwa moyo wa zida kumakhudzana ndi kuvala kwa zida, kusintha koyenera kukonzedwa, mawonekedwe apamwamba, phokoso lodula, ndi kutentha kwachangu. Pozindikira momwe zinthu zimagwirira ntchito, ndikofunikira kuchita kafukufuku molingana ndi momwe zilili. Pazinthu zovuta kukonza monga chitsulo chosapanga dzimbiri ndi ma aloyi osatentha, zoziziritsa kukhosi kapena masamba olimba bwino angagwiritsidwe ntchito.

Momwe mungadziwire zinthu zitatu za kudula

Momwe mungasankhire zinthu zitatu izi molondola ndizomwe zili muzitsulo zodulira mfundo. Kukonza zitsulo za WeChat kumatulutsa mfundo zina zazikulu. Mfundo zazikuluzikulu posankha zinthu zitatuzi ndi:

(1) Kudula liwiro (liwiro la mzere, liwiro lozungulira) V (m/min)

Kuti musankhe kuchuluka kwa masinthidwe a spindle pamphindi, muyenera kudziwa kaye kuchuluka kwa liwiro la mzere V. Kusankhidwa kwa V: Zimatengera chida, zida zogwirira ntchito, zinthu zogwirira ntchito, etc.

Zida zothandizira:

Pa carbide ya simenti, V ikhoza kukhala yokwera, nthawi zambiri kuposa 100m / min. Nthawi zambiri, magawo aumisiri amaperekedwa pogula tsamba:

Ma liwiro angati liniya akhoza kusankhidwa pokonza zinthu ziti. Chitsulo chothamanga kwambiri: V chikhoza kukhala chochepa, nthawi zambiri sichiposa 70 m / min, ndipo nthawi zambiri chimakhala chochepera 20-30 m / min.

Zida zogwirira ntchito:

Kwa kuuma kwakukulu, mtengo wa V ndi wotsika; kwa chitsulo chosungunuka, mtengo wa V ndi wotsika. Pamene chida ndi simenti carbide, akhoza kukhala 70 ~ 80 m/mphindi; kwa chitsulo chochepa cha carbon, V akhoza kukhala oposa 100 m / min. Pazitsulo zopanda chitsulo, V ikhoza kukhala yokwera (100 ~ 200m / min). Pazitsulo zolimba ndi zitsulo zosapanga dzimbiri, V iyenera kukhala yotsika.

Kukonzekera:

Kwa makina ovuta, V ayenera kukhala otsika; pomaliza, V ayenera kukhala apamwamba. Dongosolo lolimba la chida cha makina, chogwirira ntchito, ndi chida ndichosauka, ndipo V yakhazikitsidwa kukhala yotsika. Ngati S yogwiritsidwa ntchito ndi pulogalamu ya CNC ndi chiwerengero cha kusintha kwa spindle pamphindi, ndiye kuti S iyenera kuwerengedwa molingana ndi gawo la workpiece ndi kudula liniya liwiro V: S (kusintha kwa spindle pamphindi) = V (kudula liniya liwiro) * 1000 / (3.1416 * workpiece Diameter) Ngati pulogalamu ya CNC imagwiritsa ntchito liwiro lokhazikika, ndiye kuti S imatha kugwiritsa ntchito mwachindunji liwiro lodulira V (m / min)

(2) Kuchuluka kwa chakudya (kudula)

F makamaka zimadalira pamwamba roughness amafuna workpiece. Mukamaliza, zofunikira zapamtunda ndizokwera, ndipo kuchuluka kwa kudula kumakhala kochepa: 0.06 ~ 0.12mm / kuzungulira kwa spindle. Pamene roughing, ndi bwino kukhala lalikulu. Zimatsimikiziridwa makamaka ndi mphamvu ya chida. Nthawi zambiri, imatha kukhala yopitilira 0,3. Pamene mbali yaikulu yachilolezo cha chidacho ndi yaikulu, mphamvu ya chida imakhala yochepa, ndipo kuchuluka kwa chakudya sikungakhale kwakukulu. Kuonjezera apo, mphamvu ya chida cha makina, kukhwima kwa workpiece ndi chida ziyenera kuganiziridwanso. Pulogalamu ya CNC imagwiritsa ntchito magawo awiri a kuchuluka kwa chakudya: mm/min, mm/spindle per revolution, unit yomwe imagwiritsidwa ntchito pamwambapa ndi mm/spindle per revolution, ngati mugwiritsa ntchito mm/min, mutha kugwiritsa ntchito formula kutembenuza: feed per miniti= pa Kuchuluka kwa kusandulika kukhala chida * kusintha kwa spindle pamphindi

(3) Kucheka kuya (kucheka kuya)

Mukamaliza, nthawi zambiri imatha kukhala yochepera 0.5 (mtengo wa radius). Pamene roughing, zimatsimikiziridwa malinga ndi mmene workpiece, chida ndi makina chida. Nthawi zambiri, lathe yaing'ono (pazipita processing m'mimba mwake ndi m'munsimu 400mm) ntchito kutembenuza No. 45 zitsulo mu boma normalized, ndi kudula kuya mu utali wozungulira malangizo zambiri si upambana 5mm. Komanso dziwani kuti ngati spindle liwiro la lathe utenga wamba pafupipafupi kutembenuka liwiro lamulo, pamene liwiro spindle pamphindi ndi otsika kwambiri (zosakwana 100 ~ 200 rpm), linanena bungwe mphamvu ya galimoto adzakhala kwambiri yafupika. Kuzama ndi kuchuluka kwa chakudya kumatheka kokha kochepa kwambiri.

Sankhani chida moyenera

1. Mukatembenuza movutikira, sankhani chida chokhala ndi mphamvu zambiri komanso cholimba kuti mukwaniritse zofunikira zogwirira kumbuyo ndi chakudya chachikulu mukatembenuka movutikira.

2. Mukamaliza kutembenuka, sankhani zida zolondola kwambiri komanso zokhazikika kuti muwonetsetse kuti zofunikira za makina olondola.

3. Pofuna kuchepetsa nthawi yosinthira chida ndikuthandizira kukhazikitsa zida, mipeni yokhala ndi makina ndi makina omangira makina ayenera kugwiritsidwa ntchito momwe angathere.

Kusankha koyenera kwa zosintha

1. Yesani kugwiritsa ntchito mindandanda yanthawi zonse kuti muchepetse chogwirira ntchito, pewani kugwiritsa ntchito zida zapadera;

2. Gawo loyika datum limagwirizana kuti lichepetse vuto la malo.

Dziwani njira yopangira

Njira yoyendetsera ndi njira yoyendetsera ndi njira ya chida chokhudzana ndi gawo panthawi yokonza makina oyendetsedwa ndi index.

1. Iyenera kuwonetsetsa kulondola kwa kukonza ndi kuuma kwapamwamba;

2. Njira yoyendetsera iyenera kufupikitsidwa momwe mungathere kuti muchepetse nthawi yoyenda yopanda ntchito.

Mgwirizano wapakati pa processing njira ndi processing allowance

Pakalipano, pansi pa chikhalidwe chakuti CNC lathe sichinafike pa kugwiritsidwa ntchito kotchuka, malire owonjezera pa chopanda kanthu, makamaka malire omwe ali ndi khungu lolimba la khungu, ayenera kukonzedwa pa lathe wamba kuti akonze. Ngati muyenera kugwiritsa ntchito lathe ya CNC kuti mukonze, muyenera kulabadira kusinthika kwa pulogalamuyo.

Mfundo zazikuluzikulu zoyika zida

Pakadali pano, kulumikizana pakati pa hydraulic chuck ndi hydraulic clamping cylinder kumazindikirika ndi ndodo ya tayi. Mfundo zazikuluzikulu za hydraulic chuck clamping ndi izi: Choyamba, gwiritsani ntchito dzanja losuntha kuchotsa mtedza pa silinda ya hydraulic, chotsani chubu chokoka, ndikuchikoka kumbuyo kwa nsonga. Gwiritsani ntchito dzanja losuntha kuchotsa chuck fixing screw kuchotsa chuck.
