Sib tsoo yog ib txoj kev txiav workpiece ntawm lub grinder nrog kev sib tsoo log raws li cov cuab yeej txiav.
Cov yam ntxwv ntawm txoj kev no yog raws li nram no:
1. Vim tias qhov siab hardness thiab kub tsis kam ntawm kev sib tsoo log abrasives, kev sib tsoo tuaj yeem ua cov ntaub ntawv nrog cov tawv tawv, xws li cov hlau tawv tawv, cemented carbide, thiab lwm yam.
2. Cov yam ntxwv ntawm kev sib tsoo lub log thiab lub tshuab sib tsoo txiav txim siab tias cov txheej txheem sib tsoo tuaj yeem siv los ua cov txheej txheem micro-txiav, feem ntau ap = 0.001 ~ 0.005mm;kev sib tsoo ceev yog siab heev, feem ntau mus txog v = 30 ~ 50m / s;lub tshuab sib tsoo muaj qhov nruj zoo;Cov hydraulic kis tau tus mob yog siv, yog li kev sib tsoo tuaj yeem tau txais kev ua haujlwm siab (IT6 ~ IT5) thiab me me roughness (Ra = 0.8 ~ 0.2um).Sib tsoo yog ib txoj hauv kev tseem ceeb ntawm kev ua cov khoom.
3. Qhov kub ntawm qhov sib tsoo yog qhov siab heev vim muaj kev sib txhuam hnyav.Qhov no yuav ua rau muaj kev ntxhov siab thiab deformation ntawm lub workpiece, thiab tseem ua rau kub hnyiab ntawm lub workpiece.Yog li ntawd, ib tug loj npaum li cas ntawm coolant yuav tsum tau txhaj rau hauv cov txheej txheem sib tsoo kom txo tau qhov sib tsoo kub.Coolant kuj ua raws li nti tshem tawm thiab lubrication
4. Lub zog radial thaum sib tsoo yog loj heev.Qhov no yuav ua rau lub elastic concession ntawm lub tshuab cuab yeej-sib tsoo log-workpiece system, thiaj li hais tias qhov tseeb qhov tob ntawm txiav yog tsawg tshaj li qhov nominal qhov tob.Yog li ntawd, thaum kev sib tsoo yuav ua tiav, lub cutter yuav tsum tsis txhob muab tua kom tshem tawm qhov yuam kev.
5. Tom qab kev sib tsoo abrasive yog blunt, kev sib tsoo quab yuam kuj nce, uas ua rau cov khoom abrasive tawg los yog poob tawm thiab rov nthuav tawm cov ntug ntse.Cov yam ntxwv no dhau los ua "tus kheej-sharpening".Self-sharpening ua rau sib tsoo ua hauj lwm ib txwm nyob rau hauv ib tug tej lub sij hawm ntawm lub sij hawm, tab sis tom qab ib tug tej lub sij hawm ua hauj lwm, nws yuav tsum tau kho manually kom tsis txhob muaj kev co, suab nrov thiab kev puas tsuaj rau lub nto zoo ntawm lub workpiece los ntawm kev sib tsoo quab yuam.
Sib tsoo log
Sib tsoo lub log yog cov cuab yeej txiav rau kev sib tsoo.Nws muaj ntau yam me me thiab tawv abrasives thiab binders, uas yog ua los ntawm ntau yam khoom hollow.Abrasive hais ncaj qha dais kev ua hauj lwm txiav, yuav tsum yog ntse thiab muaj siab hardness, kub tsis kam thiab ib tug tej degree ntawm toughness.Feem ntau siv abrasives yog alumina (tseem hu ua corundum) thiab silicon carbide.
Alumina
Alumina Abrasives muaj siab hardness, zoo toughness thiab haum rau kev sib tsoo hlau.Silicon carbide abrasives muaj zog dua, sharper thiab zoo thermal conductivity, tab sis lawv yog nkig thiab haum rau kev sib tsoo cam khwb cia hlau thiab cemented carbide.
Tib lub abrasive sib tsoo lub log, vim nws qhov sib txawv tuab, qhov roughness ntawm qhov chaw thiab kev ua haujlwm ntawm lub workpiece tom qab ua haujlwm txawv.Cov coarse abrasive yog siv rau kev sib tsoo ntxhib.Lub finer lub abrasive yog, lub coarser lub abrasive yog, qhov me me particle loj yog.
Binders ua raws li kev sib txuas abrasives.
Ceramic binder feem ntau yog siv, ua raws li resin binder.Kev xaiv cov ntawv sib txawv cuam tshuam rau kev tiv thaiv corrosion, lub zog, kub tsis kam thiab toughness ntawm kev sib tsoo log.
Qhov nyuaj tshaj qhov abrasive daim ntawv cog lus yog, qhov nyuaj nws yog poob ntawm lub sib tsoo log.Uas yog hais tias, lub hardness ntawm lub sib tsoo log yog hais txog lub degree uas cov abrasive hais nyob rau saum npoo ntawm lub sib tsoo log poob 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 yog ob lub ntsiab lus sib txawv.Qhov saum npoo ntawm cov khoom sib tsoo yog mos, thiab ntug (ntug) ntawm cov khoom abrasive tsis yooj yim rau hnav, yog li cov khoom siv abrasive tuaj yeem siv tau ntev dua, uas yog hais tias, kev sib tsoo lub log nrog kev sib raug zoo ( lub sib tsoo log nrog ntau dua hardness) tuaj yeem xaiv.Ntawm qhov tsis sib xws, kev sib tsoo lub log nrog qis hardness yog tsim rau kev sib tsoo lub workpiece nrog siab hardness.
Txhawm rau kom muaj kev nyab xeeb, kev sib tsoo lub log yuav tsum tau kuaj xyuas ua ntej kev teeb tsa, thiab yuav tsum tsis txhob muaj qhov tawg thiab lwm yam tsis xws luag.Txhawm rau ua kom lub log sib tsoo ua haujlwm zoo, kev ntsuas qhov sib npaug yuav tsum tau ua ua ntej siv.
Thaum lub log sib tsoo ua haujlwm rau ib lub sijhawm, cov voids saum npoo yuav raug thaiv los ntawm cov khib nyiab, lub kaum ntse ntse ntawm cov abrasive yuav blunt, thiab cov duab geometric qub yuav raug cuam tshuam.Yog li ntawd, nws yog ib qho tsim nyog yuav tau luas kom rov qab txiav peev xwm thiab kho geometry.Kev sib tsoo lub log yuav tsum tau txiav nrog pob zeb diamond cwj mem.
Structure thiab Sib Tsoo Motion ntawm Nto Sib Tsoo Tshuab
Muaj ntau ntau hom kev sib tsoo, xws li nto grinder, cylindrical grinder, sab hauv grinder, universal cylindrical grinder (kuj tuaj yeem zom cov qhov hauv), iav grinder, xov grinder, qhia tsheb ciav hlau grinder, centerless grinder (sib tsoo sab nraud lub voj voog) thiab cov cuab yeej grinder ( sib tsoo cuab yeej).Lub nto grinder thiab nws cov lus tsa suab tau qhia ntawm no.
1. Cov qauv ntawm qhov chaw grinder (noj M7120A ua piv txwv: M-grinder hom tshuab cuab yeej; 71-horizontal axis moment table type deg grinder; 20-working table width 200 mm; A-thawj loj txhim kho).
