Ib qho Point Pob Zeb Diamond Hnav yog ib txoj hauv kev hnav khaub ncaws vitrified bond sib tsoo log. Txoj kev hnav khaub ncaws no feem ntau ua rau tsis ruaj khovsib tsoolog kev ua tau zoo, yog li txoj kev hnav khaub ncaws thiab cov txheej txheem yuav tsum tau kho kom haum. Thaum sib tsoo lub workpiece, txoj kev raug yog: ntxhib sib tsoo ib tug tej yam machining nyiaj nrog lub sib tsoo log, ces hloov cov hnav tsis kam, thiab ces zoo sib tsoo lub workpiece.
Feem ntau, thaumntxhib sib tsoo log trimming, lub pob zeb diamond tau nrawm nrawm nrawm raws lub voj voog sab nrauv ntawm lub log sib tsoo, thaum lub sij hawm zoo trimming, tus ntoo khaub lig pub ceev ntawm tus corrector yog heev txo kom tau cov sib tsoo log nto thiab workpiece nto. Ib txoj kev kho hu ua "overlapping" lossis "ib nrab overlapping" tuaj yeem ua kom kho tau raug thiab ruaj khov. Piv txwv li, ib lub log nrog ib txoj kab uas hla ntawm 406.4mm, qhov ceev ntawm 6000sfm (1828m / min), ib qho taw tes pob zeb diamond corrector lub vojvoog ntawm 0.254mm rau kev sib tsoo thiab hnav khaub ncaws, thiab hnav khaub ncaws tus nqi ntawm txhua tus mob stroke yog 0.025mm.
Tus ntoo khaub lig pub ceev uas feem ntau siv hauv kev kho dav dav yog feem ntau nrawm heev, yog li ntawd ib feem ntawm qhov sib tsoo lub log tsis tuaj yeem kho. Qhov saum npoo ntawm lub log sib tsoo tuaj yeem kho tau los ntawm ntau yam strokes, tab sis qhov nto tsis sib xws. Hom kev sib tsoo no muaj kev sib tsoo siab, tab sis nws hnav yog ceev thiab tsis sib xws.Sib tsoo logkev hnav khaub ncaws feem ntau yog nqa tawm ntawm kev sib tsoo ceev. Qhov tsuas yog qhov tshwj xeeb yog qhov scraping, shaping thiab trimming yog nqa tawm ntawm qhov ceev ntawm 300 sfm (91.44 m / min).
Tus ntoo khaub lig pub ceev yuav tsum raug xam thiab txiav txim siab raws li lub pob zeb diamond loj ntawm tus neeg hnav khaub ncaws thiab cov kev xav tau ntawm qhov chaw sib tsoo. Feem ntau, 2 ~ 3 laps yog siv rau kev sib tsoo ntxhib, thiab 4 ~ 6 laps yog xav tau rau kev sib tsoo zoo. Kev suav ntawm tus ntoo khaub lig pub ceev ntawm corrector: paub pob zeb diamond arc vojvoog (XB = 0.015 "), pob zeb diamond nkag (0.001"), thiab sib tsoo log ceev ntawm 1400rpm. Qhov kev ncua deb CB yog xam raws li nram no: XB = 0.015", CX = 0.015" - 0.001 "= 0.014". CB = 0.00735, AB = 2 CB = 0.0147".
Nyob rau hauv txoj kev no, pub pitch ntawm pob zeb diamond ib lub kiv puag ncig yog tau los xyuas kom meej tias tsis muaj qhov tsis tiav ntawm qhov sib tsoo log. Hloov mus rau qhov pub ceev AB ib feeb × 1400rpm = 20.58ipm. Qhov kev ceev no ua rau lub pob zeb diamond npog tag nrho lub log saum npoo hauv ib qho hnav khaub ncaws. Yog tiastxiavyuav tsum tau thib ob lapping, pub ceev yog halved rau 10.29ipm. Nws yog qhov zoo tagnrho rau kev ntxhib los mos. Kev ua tiav zoo yuav tsum tau 4 ~ 6 zaug ntawm lapping, thiab kev pub ceev yuav tsum raug txo kom raug. Piv txwv li, nws yog 5.14ipm rau 4 zaug ntawm lapping.
