CNC lathe izakhono inkqubo machining

I-CNC lathe luhlobo lwesixhobo somatshini esichanekileyo esichanekileyo kunye nomgangatho ophezulu. Ukusetyenziswa kwe-CNC lathe kunokuphucula ukusebenza kakuhle komatshini kunye nokudala ixabiso elingakumbi. Ukuvela kwe-CNC lathe kwenze ukuba amashishini alahle itekhnoloji yokulungisa ngasemva. Itekhnoloji yeCNC lathe processing ithelekiswa neelathe eziqhelekileyo. Inkqubo yomatshini iyafana, kodwa ngenxa yokuba i-CNC lathe i-clamping yexesha elinye kunye nomatshini ozenzekelayo oqhubekayo wokugqiba zonke iinkqubo zokuguqula, le miba ilandelayo kufuneka inikwe ingqalelo.

Ukhetho olufanelekileyo lwexabiso lokusika

Ukucutshungulwa kwensimbi ephezulu, izinto eziza kucutshungulwa, izixhobo zokusika, kunye neemeko zokusika zizinto ezintathu eziphambili. Oku kugqiba ixesha lokucubungula, ubomi besixhobo kunye nomgangatho wokucubungula. Indlela yoqoqosho kunye nesebenzayo yomatshini kufuneka ibe yinto efanelekileyo yokukhetha iimeko zokusika.

Izinto ezintathu zeemeko zokusika: isantya sokusika, izinga lokutya kunye nobunzulu bokusika ngokuthe ngqo kubangela umonakalo wesixhobo. Ngokunyuka kwesantya sokusika, iqondo lokushisa lesixhobo liya kunyuka, eliya kubangela ukunxiba komatshini, imichiza kunye ne-thermal. Isantya sokusika sande nge-20%, ubomi besixhobo buya kuncitshiswa nge-1/2.

Ubudlelwane phakathi kwemeko yokutya kunye nokunxiba ngasemva kwesixhobo kwenzeka kuluhlu oluncinci kakhulu. Nangona kunjalo, izinga lokutya likhulu, izinga lokushisa lokusika liyenyuka, kwaye umva wokunxiba ukhulu. Inempembelelo encinci kwisixhobo kunesantya sokusika. Nangona impembelelo yokusika ubunzulu kwisixhobo ayinkulu njengesantya sokusika kunye nesantya sokutya, xa usika ubunzulu obuncinci bokusikwa, izinto eziza kunqunyulwa ziya kuvelisa uluhlu oluqinileyo, oluya kuchaphazela ubomi besixhobo. .

Umsebenzisi kufuneka akhethe isantya sokusika esiza kusetyenziswa ngokwezinto ezicwangcisiweyo, ubunzima, imeko yokusika, uhlobo lwezinto eziphathekayo, izinga lokutya, ubunzulu bokusika, njl.

Ukukhethwa kwezona meko zifanelekileyo zokucubungula zikhethwa ngokusekelwe kwezi zinto. Ukugqoka rhoqo, okuzinzileyo kunye nokuphila ixesha elide ziimeko ezifanelekileyo.

Nangona kunjalo, kwimisebenzi yokwenyani, ukhetho lobomi besixhobo lunxulumene nokunxitywa kwesixhobo, utshintsho olunobungakanani obufanele ukusetyenzwa, umgangatho womphezulu, ingxolo yokusika, kunye nobushushu bokuqhuba. Xa umisela iimeko zokucubungula, kuyimfuneko ukuqhuba uphando ngokwemeko yangempela. Kwiimathiriyeli ezinzima-ukusetyenzwa njengentsimbi engatyiwa kunye ne-alloys ekwazi ukumelana nobushushu, ii-coolants okanye ii-blades ezinobulukhuni obuhle zingasetyenziswa.

Indlela yokumisela izinto ezintathu zokusika

Indlela yokukhetha ezi zinto zintathu ngokuchanekileyo ngumxholo oyintloko wekhosi yomgaqo wokusika isinyithi. I-metal processing WeChat ikhupha ezinye zeengongoma eziphambili. Imigaqo esisiseko yokukhetha le miba mithathu yile:

(1) Isantya sokusika (isantya somgca, isantya sokujikeleza) V (m/min)

Ukukhetha inani lee-spindle revolutions ngomzuzu, kufuneka uqale wazi ukuba ingakanani na i-V yesantya somgca wokusika. Ukhetho lwe-V: kuxhomekeke kwisixhobo, izixhobo zokusebenza, iimeko zokusetyenzwa, njl.

Isixhobo sezixhobo:

Kwi-carbide ene-cemented, i-V ingaba phezulu, ngokubanzi ngaphezu kwe-100m / min. Ngokubanzi, iiparamitha zobugcisa zibonelelwa xa kuthengwa iblade:

Zingaphi izantya zomgca ezinokuthi zikhethwe xa kusenziwa ukuba yeyiphi imathiriyeli. Insimbi enesantya esiphezulu: I-V ingaba phantsi kuphela, ngokuqhelekileyo ingabi ngaphezu kwe-70 m / min, kwaye kwiimeko ezininzi, ingaphantsi kwe-20-30 m / min.

Isixhobo somsebenzi:

Ngobunzima obuphezulu, ixabiso le-V liphantsi; kwintsimbi etyhidiweyo, ixabiso le-V liphantsi. Xa isixhobo sesixhobo se-cemented carbide, sinokuba ngu-70 ~ 80 m / min; kwintsimbi ye-carbon ephantsi, i-V ingaba ngaphezu kwe-100 m / min. Ngezinyithi ezingenayo i-ferrous, i-V ingaba phezulu (100 ~ 200m / min). Kwintsimbi eqinile kunye nensimbi engenasici, i-V kufuneka ibe ngaphantsi.

Iimeko zokuqhubekekisa:

Kumashini arhabaxa, u-V kufuneka abe ngaphantsi; ukugqiba, u-V kufuneka abe phezulu. Inkqubo engqongqo yesixhobo somatshini, i-workpiece, kunye nesixhobo ihlwempuzekile, kwaye i-V imiselwe ukuba iphantsi. Ukuba i-S esetyenziswa yiprogram ye-CNC linani lokuguqulwa kwe-spindle ngomzuzu, ngoko i-S kufuneka ibalwe ngokwedayamitha ye-workpiece kunye nokusika isantya somgca V: S (i-spindle revolutions ngomzuzu) = V (ukusika isantya somgca) * 1000 / (3.1416 * I-workpiece Diameter) Ukuba inkqubo ye-CNC isebenzisa isantya esisisigxina somgca, ngoko i-S ingasebenzisa ngokuthe ngqo i-speed linear speed V (m / min)

(2) Isixa sesondlo (isixa esinqunyulwayo)

F ubukhulu becala kuxhomekeke kwiimfuno zoburhabaxa bomphezulu womsebenzi. Xa ugqiba, iimfuno zobuso ziphezulu, kwaye inani lokusika lincinci: 0.06 ~ 0.12mm / ukujikeleza kwe-spindle. Xa urhabaxa, kungcono ukuba mkhulu. Ikakhulu inqunywe ngamandla esixhobo. Ngokuqhelekileyo, ingaba ngaphezu kwe-0.3. Xa i-angle yokucoca i-angle yesixhobo inkulu, amandla esixhobo ampofu, kwaye isixa sokutya asikwazi ukuba sikhulu kakhulu. Ukongezelela, amandla omatshini womatshini, ukuqina komsebenzi kunye nesixhobo kufuneka kuqwalaselwe. Inkqubo ye-CNC isebenzisa iiyunithi ezimbini zesantya sokutya: mm / min, mm / spindle nge-revolution, iyunithi esetyenzisiweyo ngasentla ngu-mm / spindle nge-revolution, ukuba usebenzisa i-mm / min, ungasebenzisa ifomula ukuguqula: feed ngomzuzu= ngokwe Ubungakanani bokujika kwisixhobo * ujikelo lwe spindle ngomzuzu

(3) Ukusika ubunzulu (ukusika ubunzulu)

Xa kugqitywa, ngokubanzi kunokuba ngaphantsi kwe-0.5 (ixabiso le-radius). Xa i-roughing, inqunywe ngokwemeko ye-workpiece, isixhobo kunye nesixhobo somatshini. Ngokuqhelekileyo, i-lathe encinci (i-diameter enkulu yokucubungula ingaphantsi kwe-400mm) isetyenziselwa ukuguqula i-No. Kwakhona qaphela ukuba ukuba isantya sokusonta se-lathe sithatha ummiselo wesantya sokuguqula isantya esiqhelekileyo, xa isantya sokusonta ngomzuzu sisezantsi kakhulu (ngaphantsi kwe-100 ~ 200 rpm), amandla emveliso yemoto aya kuncitshiswa kakhulu. Ubunzulu kunye nesantya sokutya sinokufezekiswa kancinci kakhulu.

Khetha isixhobo ngokufanelekileyo

1. Xa ujika rhabaxa, khetha isixhobo esinamandla aphezulu kunye nokuqina okuhle ukuhlangabezana neemfuno zokubamba umva omkhulu kunye nesondlo esikhulu xa ujika rhabaxa.

2. Xa ugqiba ukujika, khetha izixhobo ezichanekileyo kunye neziqinileyo zokuqinisekisa iimfuno zokuchaneka komatshini.

3. Ukuze kuncitshiswe ixesha lokutshintsha isixhobo kunye nokuququzelela ukusetwa kwesixhobo, iimela ezidityanisiweyo zomatshini kunye neeblade ezibambene ngomatshini kufuneka zisetyenziswe kangangoko kunokwenzeka.

Ukukhetha okufanelekileyo kwezixhobo

1. Zama ukusebenzisa izixhobo eziqhelekileyo ukuze ubambe i-workpiece, ugweme ukusebenzisa izixhobo ezikhethekileyo;

2. Idatum yokubeka inxalenye ihambelana nokunciphisa impazamo yokubeka.

Qinisekisa indlela yokucubungula

Indlela yokucubungula yindlela yokuhamba kunye nolwalathiso lwesixhobo esinxulumene nenxalenye ngexesha lokulungiswa kwesixhobo somatshini olawulwa yisalathisi.

1. Kufuneka ikwazi ukuqinisekisa ukuchaneka kokulungiswa kunye neemfuno zobunzima bomphezulu;

2. Indlela yokucubungula kufuneka icuthwe kangangoko kunokwenzeka ukunciphisa isixhobo ixesha lokuhamba lingasebenzi.

Ubudlelwane phakathi kwendlela yokusebenza kunye nesibonelelo sokuqhubekeka

Okwangoku, phantsi komqathango wokuba i-lathe ye-CNC ayifikelelanga kusetyenziso oludumileyo, umda ogqithileyo kwindawo engenanto, ngakumbi umda oqulathe i-forging and casting hard skin layer, ifanele icwangciswe kwi-lathe eqhelekileyo ukuze ilungiswe. Ukuba kufuneka usebenzise i-lathe ye-CNC ukwenza inkqubo, kufuneka ubeke ingqalelo kulungiselelo oluguquguqukayo lweprogram.

Amanqaku aphambili ofakelo lwezixhobo

Okwangoku, uxhulumaniso phakathi kwe-hydraulic chuck kunye ne-hydraulic clamping cylinder ibonwa ngentonga yokubopha. Amanqaku aphambili e-hydraulic chuck clamping ami ngolu hlobo lulandelayo: Okokuqala, sebenzisa isandla esishukumisayo ukususa i-nut kwi-cylinder ye-hydraulic, susa ityhubhu yokutsala, kwaye uyikhuphe ukusuka ekupheleni kwe-spindle. Sebenzisa isandla esishukumisayo ukususa i-chuck fixing screw ukususa i-chuck.
