Sib tsoo logyog ib hom kev txiav ua hauj lwm, yog ib yam ntawm cov cuab yeej abrasive. Hauv kev sib tsoo lub log, lub abrasive muaj qhov ua haujlwm zoo ib yam li cov serrations hauv cov saw hniav. Tab sis tsis zoo li ib rab riam, uas muaj serrations tsuas yog nyob rau ntawm ntug, lub abrasive ntawm ib tug sib tsoo log yog muab faib thoob plaws hauv lub log. Ntau txhiab qhov nyuaj abrasive yog txav mus thoob plaws lub workpiece kom tshem tawm cov khoom me me.
Feem ntau cov khoom siv abrasive yuav muab ntau yam khoom siv rau ntau yam kev sib tsoo hauv kev ua hlau. Xaiv cov khoom tsis raug tuaj yeem raug nqi ntau lub sijhawm thiab nyiaj txiag. Daim ntawv no muab qee lub hauv paus ntsiab lus los xaiv lub log sib tsoo zoo tshaj plaws.
Abrasive: hom xuab zeb
Sib tsoo log los yog lwm yam sib tsoo pob zeb muaj ob lub ntsiab lus tseem ceeb:
Cov grits uas ua tau qhov txiav, thiab kev sib xyaw ua ke uas tuav cov grits ua ke thiab txhawb cov grits thaum txiav. Cov qauv ntawm cov sib tsoo log yog txiav txim los ntawm qhov sib piv ntawm abrasive, khi thiab void ntawm lawv.
Cov abrasives tshwj xeeb siv hauv kev sib tsoo log raug xaiv raws li txoj kev uas lawv cuam tshuam nrog cov khoom siv ua haujlwm. Qhov zoo tshaj plaws abrasive yog ib qho uas muaj peev xwm nyob twj ywm ntse thiab tsis yooj yim blunted. Thaum passivation pib, lub abrasive yuav tawg los tsim cov ntsiab lus tshiab. Txhua hom abrasive yog qhov tshwj xeeb, muaj qhov sib txawv hardness, lub zog, tawg toughness thiab cuam tshuam tsis kam.
Alumina yog feem ntau siv abrasive hauv kev sib tsoo log.
Nws yog feem ntau siv los zom cov pa roj carbon steel, alloy steel, kev kub ceev steel, malleable cam khwb cia hlau, wrought hlau, bronze thiab cov hlau zoo sib xws. Muaj ntau ntau hom alumina abrasives, txhua qhov tshwj xeeb tsim thiab sib xyaw rau ib hom kev sib tsoo. Txhua hom alumina muaj nws lub npe: feem ntau yog ua ke ntawm cov tsiaj ntawv thiab cov lej. Cov npe no yuav txawv ntawm cov chaw tsim khoom rau cov chaw tsim khoom.
Zirconia aluminayog lwm series ntawm abrasives, ua los ntawm kev sib xyaw alumina thiab zirconia nyob rau hauv sib txawv proportions. Qhov kev sib xyaw ua ke no ua rau muaj zog, ruaj khov abrasive uas ua tau zoo hauv kev sib tsoo daim ntawv thov, xws li hauv kev ua haujlwm txiav. Kuj tseem siv tau rau txhua yam hlau thiab hlau alloy.
Raws li nrog alumina, ntau ntau hom zirconia alumina muaj.
Silicon carbide yog lwm yam abrasive siv los zom grey hlau, hlau txias, tooj dag, tooj dag thiab txhuas, nrog rau pob zeb, roj hmab thiab lwm yam hlau tsis muaj hlau.
Ceramic aluminayog qhov kev txhim kho tseem ceeb kawg hauv cov txheej txheem abrasive. Nws yog ib tug siab purity grain ua los ntawm gel sintering txheej txheem. Qhov no abrasive tuaj yeem tawg micron nplai ntawm kev tswj ceev. Nyob rau hauv lem, ntau txhiab lub ntsiab lus tshiab tau tsim. Ceramic alumina abrasives yog ib qho nyuaj heev thiab siv nyob rau hauv kev thov precision sib tsoo steel. Lawv feem ntau tov nrog lwm cov abrasives nyob rau hauv sib txawv proportions kom optimize lawv cov kev ua tau zoo nyob rau hauv sib txawv cov ntaub ntawv thiab kev siv.
