Kuchiza pamwamba ndi njira yopangira mawonekedwe apamwamba pamwamba pa gawo lapansi la zinthu zomwe zimakhala zosiyana ndi makina, thupi ndi mankhwala a gawo lapansi.Cholinga cha chithandizo chapamwamba ndikukwaniritsa kukana kwa dzimbiri, kukana kuvala, kukongoletsa kapena zofunikira zina zapadera za chinthucho.Pakuti castings zitsulo, ife zambiri ntchito pamwamba mankhwala njira ndi kupukuta makina, mankhwala mankhwala, pamwamba kutentha mankhwala, kupopera madzi pamwamba, mankhwala pamwamba ndi kuyeretsa, kuyeretsa, deburring, degreasing, deoxide, etc. pamwamba workpiece.
Electrolysis ndi njira yomwe kaphatikizidwe ka mankhwala a zinthu zoyera kwambiri komanso chithandizo chapamwamba cha zinthu zam'madzi zimayendetsedwa ndi machitidwe a electrochemical omwe amapezeka pakati pa ma elekitirodi monga chowongolera zamagetsi ndi electrolyte ngati kondakitala ion.
Kupukuta kumatanthawuza kugwiritsa ntchito makina, mankhwala kapena electrochemical kanthu kuti muchepetse roughness ya pamwamba pa workpiece kuti mupeze njira yowala komanso yosalala pamwamba.Ndi ntchito zida kupukuta ndi abrasive particles kapena zina kupukuta TV kusintha pamwamba workpiece.
Njira yopangira mchenga imagwiritsa ntchito mpweya wothinikizidwa ngati mphamvu yopangira mtengo wothamanga kwambiri, ndikupopera zinthu zopopera pamwamba pa workpiece kuti ziwonongeke mofulumira kwambiri, kuti maonekedwe a kunja kwa workpiece asinthe.Chifukwa cha kukhudza ndi kudula zotsatira za abrasive pamwamba pa workpiece, pamwamba pa workpiece Pezani mlingo wina wa ukhondo ndi roughness osiyana, kuti makina katundu wa workpiece pamwamba bwino.
Oxidation imatanthawuza kuthekera kwa chinthu kupeza ma elekitironi.Zinthu zomwe zili m'chigawo chapamwamba cha valence komanso zinthu zopanda zitsulo (monga fluorine, klorini, okosijeni, ndi zina zotero) nthawi zambiri zimakhala oxidizing.The makutidwe ndi okosijeni mankhwala zitsulo ndi mogwirizana zitsulo pamwamba ndi mpweya kapena okosijeni kupanga zoteteza okusayidi filimu kuteteza zitsulo dzimbiri.
Electroplating ndi chitsulo pamwamba pa chithandizo chomwe chimaphatikizapo kupaka wosanjikiza woonda kwambiri wa chitsulo china kapena aloyi yachitsulo pagawo lachitsulo kuteteza dzimbiri ndi makutidwe ndi okosijeni a workpiece, kapena kusintha mawonekedwe ake.Tini, faifi tambala, zinki (malata) ndi chromium zonse ndi electroplating zitsulo wamba, pamene mkuwa ndi carbon steel ndi zitsulo ziwiri zofala zimene amagwiritsa electroplating njira.
Laser chosema ndi kupanga zizindikiro zolondola ndi zokhazikika pazitsulo ndi mapulasitiki ena.
Kupera pamanja kumatha kuchotsa zizindikiro za makina, kuchotsa ma burrs pamwamba pazigawo, mizere yopangira ndi zomatira ndi zolakwika zina.Kuphwanyidwa kwa zigawozo kudzakhala bwino ndipo khwimbi lidzachepetsedwa kuti likwaniritse mawonekedwe osalala komanso osasinthasintha.
