Raws li peb txhua tus paub, kev sib tsoo log yog hom tseem ceeb tshaj plaws ntawm cov cuab yeej abrasive hauv kev sib tsoo. Lub log sib tsoo yog lub cev ntxeem tau ua los ntawm kev ntxiv cov hlua khi rau cov abrasive, compacting, ziab thiab tua. Vim muaj kev sib txawv abrasives, kev sib txuas cov neeg ua haujlwm thiab cov txheej txheem tsim khoom, cov yam ntxwv ntawm kev sib tsoo log sib txawv heev, uas muaj kev cuam tshuam tseem ceeb rau kev ua haujlwm zoo, kev tsim khoom thiab kev lag luam ntawm kev sib tsoo. Cov yam ntxwv ntawm kev sib tsoo log yog txiav txim siab los ntawm cov yam ntxwv xws li abrasive, lub zog, daim ntawv cog lus, hardness, qauv, cov duab thiab qhov loj me.
Raws li cov abrasives siv, nws tuaj yeem muab faib ua cov abrasives zoo tib yam (corundum thiab silicon carbide, thiab lwm yam) sib tsoo lub log thiab ntuj abrasive superabrasives thiab (pob zeb diamond thiab cubic boron nitride, thiab lwm yam) sib tsoo log;
Raws li cov duab, nws tuaj yeem muab faib ua lub log sib tsoo, bevel sib tsoo log, cylindrical sib tsoo log, khob sib tsoo log, phaj sib tsoo log thiab lwm yam.toolroom sib tsoo log; Raws li daim ntawv cog lus, nws tuaj yeem muab faib ua ceramic sib tsoo log, resin sib tsoo log, roj hmab sib tsoo log, hlau sib tsoo log, thiab lwm yam. Cov yam ntxwv ntawm cov sib tsoo log feem ntau suav nrog abrasive, viscosity, hardness, daim ntawv cog lus, zoo li, loj, thiab lwm yam. .
Txij li thaum lub log sib tsoo feem ntau ua haujlwm ntawm kev kub ceev, kev ntsuas kev sib hloov (kom paub meej tias lub log sib tsoo yuav tsis tawg ntawm qhov siab tshaj plaws kev khiav hauj lwm ceev) thiab qhov ntsuas qhov sib npaug (kom tiv thaiv kev vibration ntawm lub tshuab cuab yeej thaum ua haujlwm) yuav tsum tau ua ua ntej. siv. Tom qab kev sib tsoo lub log tau ua haujlwm rau lub sijhawm, nws yuav tsum tau hnav kom rov ua haujlwm sib tsoo thiab kho cov duab geometry.
Cov yam ntxwv ntawm kev sib tsoo log siv rau ntawm lub tshuab sib tsoo yog:
Vim muaj kev sib txhuam hnyav, qhov kub ntawm qhov sib tsoo yog qhov siab heev. Qhov no tuaj yeem ua rau muaj kev ntxhov siab thiab deformation ntawm lub workpiece, thiab txawm hlawv 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 kuj ua raws li nti tshem tawm thiab lubrication.
Lub zog radial thaum sib tsoo yog loj heev. Qhov no yuav ua rau lub elastic retreat ntawm lub tshuab cuab yeej-sib tsoo log-workpiece system, ua rau qhov tseeb qhov tob ntawm txiav tsawg tshaj li qhov nominal qhov tob ntawm txiav. Yog li ntawd, thaum kev sib tsoo yuav ua tiav, kev sib tsoo du yuav tsum tau nqa tawm yam tsis tau nkag mus rau hauv rab riam kom tshem tawm qhov yuam kev. Tom qab cov nplej abrasive yog blunted, kev sib tsoo quab yuam kuj nce, ua rau cov nplej abrasive tawg los yog poob, rov nthuav tawm cov ntug ntse. Qhov no feature hu ua self-sharpening. Self-sharpening enables ib txwm sib tsoo nyob rau hauv ib lub sij hawm ntawm lub sij hawm. Txawm li cas los xij, tom qab qee lub sijhawm ua haujlwm, nws yuav tsum tau txiav manually kom tsis txhob muaj kev vibration, suab nrov thiab kev puas tsuaj rau qhov zoo ntawm lub workpiece los ntawm kev sib tsoo ntau zog.
Vim lub siab hardness thiab kub tsis kam ntawm kev sib tsoo log abrasive nws tus kheej, kev sib tsoo tuaj yeem ua cov ntaub ntawv nrog cov hardness siab, xws li hardened steel thiab cemented carbide. 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 ua tau zoo li micro-txiav, feem ntau ap=0001-0.005mm; kev sib tsoo ceev yog siab heev, feem ntau mus txog v=30-50m/s; lub tshuab sib tsoo muaj zoo rigidity; hydraulic kis tau tus mob yog saws, Yog li ntawd, kev sib tsoo yuav economically tau siab machining raug (IT6 ~ IT5) thiab me me nto roughness (Ra=0.8 ~ 0.2m). Sib tsoo yog ib txoj hauv kev tseem ceeb ntawm kev ua tiav.
