Nyob rau hauv precision machining iav, iav sib tsoo yog ib txoj hauv kev rau machining siab - precision iav nrog zoo nto tiav. Gears hauv av siv txoj kev no tuaj yeem ua tiav qhov tseeb ntawm 7-4. Thaum lub iav sib tsoo muaj qhov tsis zoo xws li cov cuab yeej kim, kev tsim khoom tsawg, kev xav tau siab ntawm cov neeg siv kev txawj ntse, thiab cov nqi tsim khoom siab, nws tseem muaj ntau yam zoo piv rau lwm cov iav xov (xws li iav shaving thiab iav honing).
Cov txiaj ntsig tseem ceeb ntawm kev sib tsoo iav suav nrog: qhov tseeb ntawm cov iav shaving thiab honing yog nyob ntawm qhov tseeb ntawm cov khoom ua ntej -machined iav, thiab lawv muaj peev xwm los kho qee qhov yuam kev hauv pre-machined iav. Iav shaving kuj tsis tuaj yeem ua cov iav tawv tawv, thaum lub iav sib tsoo tuaj yeem ua cov iav tawv tawv, kho ntau yam yuam kev hauv lub tshuab ua ntej -, tshem tawm deformation los ntawm kev kho cua sov, thiab ua tiav qhov tseeb dua li iav shaving thiab honing.
Cov cuab yeej siv rau kev sib tsoo iav yuav tsum xaiv qhov tsim nyogiav sib tsoo logs los xyuas kom meej qhov zoo thiab qhov tseeb ntawm cov txheej txheem sib tsoo.
I. Xaiv cov iav sib tsoo log
1. Abrasive khoom:
Thaum lub iav hauv av yog ua los ntawm cov dav dav-qib hardened alloy steel lossis siab- steel ceev, cov khoom siv abrasive yuav tsum yog dawb fused alumina (WA), liab fused alumina (PA), los yog sib tov ntawm dawb fused alumina thiab liab fused alumina.
2. Hardness:
Qhov siab dua qhov hardness ntawm lub iav yog hauv av, lub softer lub sib tsoo log yuav tsum. Thaum sib tsoo lub log nrog daim ntawv sib tsoo, vim tias qhov chaw sib cuag ntawm lub log sib tsoo yog qhov loj thiab nquag kub, yuav tsum siv lub log me ntsis softer. Txawm li cas los xij, txhawm rau tswj xyuas qhov tseeb ntawm kev sib tsoo lub log, nws yuav tsum tsis txhob muag heev. Thaum lub sij hawm qhuav sib tsoo, vim tsis zoo cua sov dissipation, lub hardness ntawm lub sib tsoo log yuav tsum kuj nyob rau hauv lub softer sab.
3. Grit Loj:
Cov grit loj yuav tsum raug xaiv los xyuas kom meej qhov yuav tsum tau cov hniav nto raug thiab nto roughness ntawm lub iav hauv av. Qhov siab dua qhov yuav tsum tau ua rau cov hniav raug thiab qhov chaw roughness, qhov zoo dua qhov grit loj yuav tsum yog.
4. Bonding Agent:
Feem ntau, tus neeg sawv cev ruaj khov ceramic yog qhov zoo dua. Rau siab- sib tsoo ceev, yuav tsum tau siv cov khoom sib tsoo tshwj xeeb uas tsim nyog rau kev sib tsoo ceev.
Thaum xaiv cov kev txwv saum toj no, kev txiav txim siab dav dav yuav tsum tau muab rau cov yam ntxwv xws li qhov tseeb ntawm cov iav hauv av, kev tsim khoom, thiab lub tshuab sib tsoo. Tsis tas li ntawd, thaum lub iav yuav tsum muaj qhov tseeb thiab qhov chaw tiav, thiab cov nyiaj sib tsoo yog qhov loj, nws yog qhov zoo tshaj plaws los xaiv cov iav sib tsoo log nrog qhov sib txawv hardness thiab grit qhov ntau thiab tsawg rau ntxhib thiab ua tiav kev sib tsoo.
II. Sib npaug ntawm cov iav sib tsoo lub log
Iav sib tsoo yog cov txheej txheem machining precision, thiab qhov sib npaug ntawm kev sib tsoo lub log yog qhov tseem ceeb tshwj xeeb. Txwv tsis pub, kev vibrations yuav tshwm sim thaum sib tsoo, cuam tshuam rau qhov chaw roughness thiab qhov tseeb ntawm cov hniav iav hauv av, thiab hauv qhov xwm txheej hnyav, txawm tias cuam tshuam rau lub neej kev pab cuam ntawm lub iav sib tsoo tshuab.
Lub log sib tsoo yuav tsum tau ua ob txoj kev ntsuas qhov zoo li qub. Tom qab thawj qhov sib npaug zoo li qub, lub log sib tsoo yog hnav zoo li qub, thiab tom qab ntawd ua tiav qhov kev sib npaug thib ob, ua raws li kev hnav khaub ncaws zoo. Rau worm sib tsoo lub log, vim lawv qhov loj me thiab qhov hnyav, kev ntsuas qhov sib npaug kuj yog qhov tsim nyog los xyuas kom meej qhov zoo thiab qhov roughness ntawm cov iav hauv av. Tam sim no, feem ntau CNC iav sib tsoo tshuab tau nruab nrog tsis siv neeg dynamic ntsuas tshuab ntawm kev sib tsoo log spindle, tab sis ceev faj zoo li qub ntsuas ob zaug tseem xav tau.
Yog tias cov iav sib tsoo tshiab yuav tsum muaj qhov tseem ceeb ntawm kev hnav khaub ncaws, nws yuav tsum tau ua kom zoo li qub ntawm lub tshuab sib tsoo ua ntej ntsuas qhov zoo li qub.
