Kev daws: Hloov mus rau qhov zoo -grit CBN vitrified log (CBN120N5V). Lub log vitrified lub siab precision thiab hnav tsis kam coj qhov kawg rau spec (Ra=0.15 μm), thiab lub log lub neej txuas ntxiv mus rau 8 teev. Tsawg lub log hloov tau txhim kho tag nrho cov txiaj ntsig los ntawm 60%. Txawm hais tias lub log vitrified raug nqi 50% ntau dua, kev ua haujlwm hauv kev ua tau zoo thiab kev ua tau zoo, tag nrho cov nqi tau nqis 30%.
Case 2: Rough sib tsoo zoo tib yam carbon steel-vitrified log ua rau cov nqi ntau dhau
Teeb meem: Sib tsoo cov pa roj carbon zoo tib yam (HRC20) nrog lub log vitrified. Lub log lub neej ntev, tab sis tus nqi pem hauv ntej yog siab, thiab thaum lub sij hawm sib tsoo nrog hnyav swarf, lub log vitrified muaj tus kheej tsis zoo -ntxhiab thiab xav tau kev hnav khaub ncaws ntau zaus, uas ua rau kev ua haujlwm zoo.
Kev daws: Hloov mus rau A46L5B resinoid log. Lub log resinoid tus kheej -ntxuav tshem tawm cov hnav khaub ncaws ntau zaus thiab tshem tawm cov khoom lag luam sai. Tus nqi nce siab tsuas yog 1/3 ntawm lub log vitrified. Txawm hais tias txhua lub log tsuas yog siv sijhawm li 2 teev xwb, cov nqi hloov pauv tau qis rau roughing, thiab tag nrho cov nqi machining poob 45% nrog rau 20% efficiency nce.
Ⅳ. Feem ntau yuam kev: Plaub xaiv yuam kev Ntau tus neeg ua
Qhov yuam kev 1: "Kim txhais tau tias zoo dua-tsuas yog yuav cov log vitrified tsis hais cov khoom siv."
