Ukuchongwa kweSixa-mali sokuQala kwakhona
⑴ Isibonelelo sokubuyisela kwakhona isibonelelo sokubuyisela kwakhona kubunzulu besikiwe ebekelwe ukuphinda kuhlaziywe kwakhona. Ngokuqhelekileyo, isibonelelo sokuphinda siphinde sifumaneke sincinci kunesixa sokufumana kwakhona okanye ukukruqula. Isibonelelo sokubuyisela kwakhona kakhulu siya kwandisa uxinzelelo lokusika kwaye sonakalise i-reamer, kubangele uburhabaxa bomgangatho ogqityiweyo. Xa umda mkhulu kakhulu, ihenjisi erhabaxa kunye nehenjisi ecolekileyo inokohlulwa ukuqinisekisa iimfuno zobugcisa.
Ngakolunye uhlangothi, ukuba isibonelelo se-billet sincinci kakhulu, i-reamer iya kuguga ngaphambi kwexesha kwaye ayinakunqunyulwa ngokuqhelekileyo, kwaye uburhabaxa bomphezulu buya kuba bubi. Ngokubanzi, isibonelelo sokubuyisela kwakhona yi-0.1 ~ 0.25mm, kwaye kwimingxuma emikhulu yobukhulu, isibonelelo asinakuba sikhulu kune-0.3mm.
Kukho amava acebisa ukuba kugcinwe ubukhulu be-1 ~ 3% ye-diameter ye-reamer njengesibonelelo sokubuyisela (ixabiso le-diameter). Umzekelo, kulunge ngakumbi ukongeza i-Φ20 ephindaphindayo enobubanzi bomngxuma malunga ne-Φ19.6: 20-(20*2/ 100)=19.6 Izibonelelo zokubuyisela amanzi zidla ngokwenziwa zibe ncinci kwizinto eziqinileyo kunye nemathiriyeli ye-aerospace.
(2) Izinga lokutya lokuphinda liphinde liphinde libe likhulu kunolo lokwemba, ngokuqhelekileyo amaxesha angama-2 ~ 3 kuwo. Injongo yezinga eliphezulu lokutya kukwenza i-reamer isike into endaweni ye-abrasive material. Nangona kunjalo, uburhabaxa bexabiso lokuphinda buphinde bunyuke ngokunyuka kwezinga lokutya. Ukuba umyinge wesondlo uncinci kakhulu, ukukhuhlana kweradial kuya kwanda, kwaye ireyiri iya kuphelelwa ngokukhawuleza, ibangele isivuseleli ukuba singcangcazele kwaye sirhabaxa umphezulu womngxuma.
Izixhobo ze-Xinfa ze-CNC zineempawu zomgangatho omhle kunye nexabiso eliphantsi. Ngeenkcukacha, nceda undwendwele:
Abavelisi beZixhobo ze-CNC-i-China CNC iFactory yeziXhobo kunye nababoneleli (xinfatools.com)
I-standard steel reamer processing steel parts, ukufumana uburhabaxa be-surface Ra0.63, umlinganiselo wokutya akufanele udlule i-0.5mm / r, kwiindawo zetsimbi ezityhidiweyo, zinokunyuswa ukuya kwi-0.85mm / r.
⑶ Ukubuyisela isantya sokujikeleza kunye nenani lokubuyisela kwakhona Zonke izinto zinempembelelo kuburhabaxa bomphezulu bomngxuma wokubuyisela, apho isantya sokubuyisela kwakhona sinempembelelo enkulu. Ukuba i-reamer yensimbi isetyenziselwa ukuhlaziya, i-roughness engcono i-Ra0.63; m , Kwi-workpieces yensimbi yekhabhoni ephakathi, isantya sokubuyisela akufanele sidlule i-5m / min, kuba i-edge eyakhiweyo ayilula ukwenzeka ngeli xesha, kwaye isantya asiphezulu; xa ulungisa intsimbi, ngenxa yokuba iitshiphusi ziqhekezwe zibe yigranular, akukho mphetho uqokelelweyo uya kwenziwa. Imiphetho, ngoko isantya sinokunyuswa ukuya kwi-8 ~ 10m / min. Ngokubanzi, isantya sokusonta sokuphinda sikhethwe njenge-2/3 yesantya sokusonta sokomba kwinto enye.
Umzekelo, ukuba isantya sokubhoboza i-spindle yi-500r/min, kunengqiqo ngakumbi ukuseta isantya sokujikeleza kwi-2/3 yayo: 500*0.660=330r/min.
Oko kubizwa ngokuba ngumxhasi ngenene uyadika. I-Fine boring ngokuqhelekileyo inomda we-unilateral ye-0.03-0.1 kunye nesantya se-300-1000. Umyinge wesondlo uphakathi kwe-30-100, kuxhomekeke ekubeni kuthiwa yimela.
