Dipatimenti yaukadaulo ya TAA imakhulupirira kuti kuwongolera kwapamwamba kumatenga gawo lofunikira kwambiri pakugwirira ntchito kwa zokutira.Zina mwazinthu zambiri zomwe zimakhudza magwiridwe antchito a zokutira, pretreatment yapamwamba ndiyo yofunika kwambiri.

Kukonzekera kwapamwamba ndi ntchito yofunikira

Kukonzekera kwapamwamba kumatha kupangitsa kuti zokutira zomwe zimagwira bwino kwambiri pazigawo ziwiri: mu makina, zimapereka kuuma kwapamwamba kwa zokutira;Ndipo mu mankhwala, amapanga mamolekyu a zokutira kuti agwirizane kwambiri ndi pamwamba pa gawo lapansi lachitsulo.

Kugonjetsa zotsatira zosalala pamwambazazokutira

Ngati pamwamba ndi yosalala, sipadzakhala kumamatira kwabwino pakati pa zokutira ndi pamwamba, ndi zokutira pamwamba akhoza kuchotsedwa khama.M'malo mwake, ngati pamwamba pa workpiece ndi ovuta ngati sandpaper, sikophweka kuchotsa zokutira.

Pambuyo pobowola (kuphulika kwa mchenga), pamwamba pazitsulo pamakhala nkhanza ngati sandpaper, zomwe nthawi zambiri timazitcha kuuma kwa pamwamba.

Zinthu zovulaza zosawoneka ndi maso

Pa mankhwala pamwamba pa dzimbiri zitsulo dongosolo pamaso penta, mbali kusonyeza dzimbiri maenje pambuyo kuwombera kuphulika (makamaka pansi pa dzimbiri maenje) akhoza kukhala sungunuka mchere.Kuwombera kowuma sikungachotse mcherewu.Choncho, musanayambe kujambula, ndi bwino kufufuza ngati pali mchere wosungunuka ndi ndende yawo pa workpiece pamwamba ndi chida chapadera choyesera kumunda.Ngati kuchuluka kwa mchere wosungunuka kupitirira mtengo wovomerezeka, njira zochotseramo ziyenera kuchitidwa.

Kuyeretsa kalasi

Economy ndivuto lomwe tiyenera kuliganizira tikamazindikira mulingo woyeretsa pamwamba.Nthawi zambiri, ukhondo ukakhala wapamwamba, mtengo woyeretsa umakhala wokwera.Pakuyeretsa pamwamba pazitsulo, zofunikira zaukhondo za mulingo woyeretsera bwino kwambiri (SA 3) ndizokwera mtengo kuposa zomwe sizimayeretsa bwino (SA 2).Kuyeretsa pamwamba pazitsulo zazitsulo zomwe zimagwiritsidwa ntchito m'malo owononga kwambiri kuyenera kufika pamtunda wapamwamba, koma nthawi zina, kukwera mtengo kwa moyo wautumiki wophimba ndi chinthu chofunikira kwambiri pakusankha mulingo woyeretsa.

The workpiece ankachitira ndi sanali zitsulo abrasive alibe Fe atomu zotsalira ndipo n'zosavuta dzimbiri ndi discolor, koma ndi mkulu kuphwanya mlingo, lalikulu fumbi ndi kuipitsidwa kwambiri, amene sagwirizana ndi zofunika kuteteza chilengedwe.TAAgrit zitsulo zosapanga dzimbiri akhoza kuthetsa bwino mavuto omwe akukumana nawo.Pamalo oyeretsera, ntchitoyo imafunika osati kuti ikhale yopanda dzimbiri komanso kutayika pambuyo pa chithandizo chapamwamba, komanso kupanga roughness inayake pamwamba ndikukwaniritsa kumamatira kokwanira pambuyo popaka.

Thezitsulogritzopangidwa ndikuwombera kwachitsulo cha carbon highimatha kukwaniritsa zofunikira mukamaliza kuyeretsa, koma ma atomu a Fe adzakhalabe pamtunda, zomwe zimapangitsa dzimbiri komanso kusinthika kwamtundu komanso kukhudza khalidwe la ❖ kuyanika.

Chitsulo chosapanga dzimbiri chodula wayazingalepheretse workpiece pamwamba pa dzimbiri ndi ma discoloration, koma adzakhala kuzungulira pa kuphulika, choncho sangathe roughness zofunika.

Chitsulo chosapanga dzimbiri ndi zosapanga dzimbiri grit tinthu tating'ono, izo sizingakhoze kokha kuthetsa vuto la dzimbiri ndi kusinthika chifukwa otsalira ma atomu Fe, komanso kupanga m'mbali ndi ngodya kupanga chofunika nangula kuya, kusintha ❖ kuyanika khalidwe ndi kukwaniritsa zofunika ❖ kuyanika.Ili ndi chiyembekezo chamsika waukulu.

Kuphatikiza apo, chitsulo chosapanga dzimbirigritakhoza m'malo osiyanasiyana mchenga mchere ndi sanali zitsulo abrasives, monga alumina okusayidi, emery, quartz mchenga, galasi mikanda, etc.

Poyerekeza ndi ma abrasives opanda zitsulo,chitsulo chosapanga dzimbirigrit zitha kubweretsa mtengo wotsika wogwirira ntchito, kuchepetsa kwambiri kutulutsa fumbi, kuchepetsa mtengo wochotsa fumbi ndikuwongolera malo ogwirira ntchito.

Kugwiritsa ntchito grit yachitsulo chosapanga dzimbiri:
