Sib tsoo logyog cov cuab yeej txiav rau kev sib tsoo, uas yog cov khoom ntxeem tau ua los ntawm ntau cov khoom me me thiab tawv abrasive thiab cov khoom sib txuas. Cov khoom abrasive ncaj qha rau ntawm lub xub pwg ntawm kev txiav ua haujlwm thiab yuav tsum tau ntse thiab muaj zog hardness, kub tsis kam thiab qee qhov toughness. Feem ntau siv abrasives yog alumina (tseem hu ua corundum) thiab silicon carbide. Alumina abrasives muaj siab hardness thiab zoo toughness, haum rau kev sib tsoo hlau. Silicon carbide abrasive hardness yog siab dua, sharper, zoo thermal conductivity, tab sis ntau nkig, haum rau sib tsoo cam khwb cia hlau thiab carbide.
Tib lub log sib tsoo, vim nws qhov sib txawv tuab, qhov roughness ntawm qhov chaw thiab kev ua haujlwm ntawm lub workpiece tom qab kev ua haujlwm tsis zoo ib yam, cov ntxhib abrasive yog siv rau kev sib tsoo ntxhib, nplua abrasive yog tsim rau kev sib tsoo zoo, coarser abrasive. , qhov me me particle loj.
Lub binder ua raws li daim ntawv cog lus rau abrasive. Ceramic binder feem ntau yog siv, ua raws li resin binder. Kev xaiv cov khoom sib txawv ntawm daim ntawv cog lus cuam tshuam rau corrosion kuj, lub zog, kub tsis kam thiab toughness ntawm lub sib tsoo log.
Lub zog abrasive daim ntawv cog lus, qhov yooj yim dua nws yog poob ntawm lub sib tsoo log, nws yog hu ua hardness ntawm lub sib tsoo log, uas yog, lub hardness ntawm lub sib tsoo log yog hais txog qhov nyuaj ntawm abrasive hais nyob rau saum npoo ntawm cov khoom. sib tsoo log ntog tawm nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam. Yooj yim rau poob yog hu ua mos, thiab vice versa yog hu ua tawv. Lub hardness ntawm kev sib tsoo log thiab abrasive hardness yog ob lub ntsiab lus sib txawv. Qhov saum npoo ntawm kev sib tsoo workpiece yog softer, thiab txiav ntug (ntug) ntawm cov khoom abrasive yog tsis yooj yim rau hnav, yog li ntawd lub abrasive yuav siv tau rau lub sij hawm ntev, uas yog hais tias, ib tug khoom sib tsoo log (siab dua hardness. sib tsoo log) tuaj yeem xaiv. Conversely, low hardness sib tsoo log yog haum rau sib tsoo high hardness workpieces.
Kev sib tsoo lub log ua haujlwm ntawm kev kub ceev, txhawm rau kom muaj kev nyab xeeb, nws yuav tsum tau kuaj xyuas ua ntej kev teeb tsa, thiab yuav tsum tsis muaj qhov tawg thiab lwm yam tsis xws luag; Txhawm rau ua kom lub log sib tsoo ua haujlwm zoo, qhov ntsuas qhov ntsuas yuav tsum tau ua ua ntej siv.
Tom qab lub log sib tsoo ua haujlwm rau qee lub sijhawm, qhov sib txawv ntawm qhov chaw yuav raug thaiv los ntawm kev sib tsoo chips, lub kaum sab xis ntawm cov abrasive yuav blunted, thiab cov geometry qub yuav raug distorted. Yog li ntawd nws yuav tsum tau muab txiav kom rov qab txiav lub zog thiab kho cov duab geometry. Lub log sib tsoo yuav tsum tau txiav nrog lub pob zeb diamond cwj mem.
Sib tsoo yog txoj kev txiav lub workpiece nrog lub sib tsoo log raws li cov cuab yeej txiav ntawm lub tshuab sib tsoo. Cov yam ntxwv ntawm txoj kev no yog:
(1) Vim tias lub log sib tsoo nws tus kheej muaj qhov hnyav thiab kub tsis kam, nws tuaj yeem ua cov khoom siv nrog cov tawv tawv, xws li cov hlau tawv tawv thiab cemented carbide.
(2) Cov yam ntxwv ntawm kev sib tsoo lub log thiab lub tshuab txiav txiav txim siab tias cov txheej txheem sib tsoo tuaj yeem ua kom tsis sib xws micro txiav, feem ntau ap=0.001 ~ 0.005mm; Kev sib tsoo ceev yog siab heev, feem ntau mus txog v=30 ~ 50m / s; Sib tsoo tshuab txhav yog zoo; Siv hydraulic kis tau tus mob, sib tsoo yuav economically tau siab machining raug (IT6 ~ IT5) thiab me me nto roughness (Ra=0.8 ~ 0.2μm). Sib tsoo yog ib txoj hauv kev tseem ceeb ntawm cov khoom tiav.
(3) Vim muaj kev sib txhuam hnyav, qhov kub ntawm qhov sib tsoo yog siab heev. Qhov no yuav ua rau muaj kev ntxhov siab thiab deformation ntawm lub workpiece, thiab tseem ua rau kub hnyiab ntawm qhov chaw ntawm lub workpiece. Yog li ntawd, ib tug loj npaum li cas ntawm coolant yuav tsum tau txhaj thaum lub sij hawm sib tsoo kom txo tau qhov sib tsoo kub. Lub coolant tuaj yeem ua lub luag haujlwm tshem tawm nti thiab lubrication.
(4) Lub zog radial thaum sib tsoo yog loj heev. Qhov no ua rau lub elasticity ntawm lub tshuab-sib tsoo-workpiece system muab txoj kev, ua qhov tseeb txiav qhov tob tsawg tshaj li qhov nominal txiav qhov tob. Yog li ntawd, thaum sib tsoo yuav tsum ua kom tiav, nws yuav tsum tau polished tsis pub noj kom tshem tawm qhov yuam kev.
(5) Tom qab lub abrasive yog blunted, lub sib tsoo quab yuam kuj nce, ua rau lub abrasive tawg los yog poob tawm, thiab re-exposing lub ntse ntug, tus yam ntxwv no hu ua "tus kheej-sharpness". Tus kheej-ntse ua rau kev sib tsoo yuav tsum tau nqa tawm ib txwm nyob rau hauv ib lub sij hawm ntawm lub sij hawm, tab sis tom qab ib tug tej lub sij hawm ua hauj lwm, nws yuav tsum tau manually trimmed kom tsis txhob muaj kev vibration, suab nrov thiab kev puas tsuaj rau lub nto zoo ntawm workpiece los ntawm kev nce ntawm cov khoom. sib tsoo quab yuam.
Cov qauv thiab kev sib tsoo ntawm qhov chaw sib tsoo tshuab
Muaj ntau ntau hom kev sib tsoo tshuab, feem ntau nto sib tsoo tshuab, sib tsoo tshuab sab nraud, sab hauv sib tsoo tshuab, universal sab nraud sib tsoo tshuab (tseem tuaj yeem sib tsoo hauv qhov), iav sib tsoo tshuab, xov sib tsoo tshuab, kev sib tsoo tshuab, tsis siv neeg sib tsoo tshuab (sib tsoo sab nraud) thiab cov cuab yeej sib tsoo (cov cuab yeej sib tsoo). Qhov chaw grinder thiab nws cov lus tsa suab tau piav qhia ntawm no.
1. Cov qauv ntawm qhov sib tsoo tshuab (miv M7120A ua piv txwv, qhov twg: M-- kev sib tsoo tshuab cuab yeej; 71-- kab rov tav ncej rectangular rooj nto sib tsoo tshuab; 20-- qhov dav ntawm lub rooj ua haujlwm yog 200mm; A-- Thawj qhov kev txhim kho loj.
