Ukukhethwa Kwenani Lokubuyisela kabusha
⑴ Isibonelelo sokubuyisela kabusha Isibonelelo sokubuyisela kabusha ukujula kokusikwa kubekelwe ukuphinda kwenziwe kabusha. Imvamisa, imvume yokuphinda ifakwe kabusha incane kunemvume yokuphinda uyikhiphe noma yokubhora. Imvume yokubuyisela kabusha eningi kakhulu izokhuphula ingcindezi yokusika futhi kulimaze isivuseleli, okuholela ekumangelekeni kwendawo ecutshunguliwe. Uma imajini inkulu kakhulu, ihinji emagebhugebhu nehinji enhle ingahlukaniswa ukuze kuqinisekiswe izidingo zobuchwepheshe.
Ngakolunye uhlangothi, uma i-billet allowance incane kakhulu, i-remer izoguga ngaphambi kwesikhathi futhi ayikwazi ukunqunywa ngokujwayelekile, futhi ukugoqa phezulu kuzoba mpofu. Ngokuvamile, isibonelelo sokubuyisela kabusha singu-0.1~0.25mm, futhi emigodini emikhulu yobubanzi, imvume ayikwazi ukuba nkulu kuno-0.3mm.
Kunokuhlangenwe nakho okusikisela ukuthi kugcinelwe ukujiya okungu-1~3% kobubanzi be-remer njengemvume yokuvuselela kabusha (inani lobubanzi). Isibonelo, kufaneleka kakhulu ukwengeza isivuseleli esingu-Φ20 esinobubanzi bembobo obucishe bube ngu-Φ19.6: 20-(20*2/ 100)=19.6 Izibonelelo zokubuyisela kabusha ngokuvamile zenziwa zibe zincane ezintweni eziqinile kanye nezinye izinto zasemkhathini.
(2) Izinga lokuphakelayo lokuphinda kwenziwe kabusha Izinga lokuphakelayo lokuphinda lifakwe likhulu kunelo lokumba, ngokuvamile izikhathi ezi-2–3 zakhona. Injongo yezinga eliphezulu lokuphakelayo iwukwenza i-remer isike into esikhundleni se-abrasive material. Kodwa-ke, ubulukhuni bevelu ye-Ra yokuvuselela kabusha bukhuphuka ngokwenyuka kwezinga lokuphakelayo. Uma izinga lokuphakelayo lilincane kakhulu, ukungqubuzana kwe-radial kuzokhuphuka, futhi isivuseleli sizoguga ngokushesha, okubangele ukuthi ophindayo adlidlize futhi enze imbobo ibe rough.
Amathuluzi e-Xinfa CNC anezici zekhwalithi enhle nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:

Insimbi ejwayelekile yokucubungula izingxenye zensimbi, ukuthola ubulukhuni obuphezulu be-Ra0.63, izinga lokuphakelayo akufanele lidlule i-0.5mm / r, izingxenye zensimbi eziphonsiwe, linganyuswa libe ngu-0.85mm / r.
⑶ Isivinini sokubuyisela kabusha isivinini sokuphotha kanye nenani lokubuyisela kabusha Zonke izici zinomthelela kubuhwaqane obungaphezulu bembobo yokubuyisela kabusha, lapho isivinini sokuvuselela sinethonya elikhulu kakhulu. Uma i-reamer yensimbi isetshenziselwa ukuvuselela kabusha, i-roughness engcono Ra0.63; m , Ukuze uthole ama-workpieces ensimbi ye-carbon ephakathi, isivinini sokuvuselela akufanele sidlule i-5m / min, ngoba umkhawulo owakhiwe akulula ukwenzeka ngalesi sikhathi, futhi isivinini asiphezulu; lapho ulungisa kabusha insimbi eyinsimbi, ngoba ama-chips aphulwa abe yi-granular, akukho umkhawulo oqoqiwe ozokwakhiwa. Imiphetho, ngakho-ke ijubane linganyuswa libe ngu-8 ~ 10m/min. Ngokuvamile, isivinini sokuphotha sokuphinda sikhethwe njenge-2/3 yejubane lokuphotha lokubhoboza kwinto efanayo.
Isibonelo, uma isivinini sokubhola sokuphotha singama-500r/min, kunengqondo kakhulu ukusetha isivinini sokuphotha kabusha ku-2/3 wayo: 500*0.660=330r/min.
Lokhu okubizwa ngokuthi i-remer empeleni kuyisicefe. Fine boring ngokuvamile has a margin unilateral of 0.03-0.1 kanye isivinini 300-1000. Izinga lokudla liphakathi kuka-30-100, kuye ngokuthi libizwa ngokuthi ummese.
