Kuyo yonke inkqubo yokusebenzisa umatshini wokupholisa ngokuzenzekelayo, umsebenzisi uhlangabezana nengxaki enkulu, ethi "i-over-polish".Ixesha lokupolisha lide kakhulu kwaye umgangatho womphezulu wesixhobo sokubumba awulungile.Kwiimeko eziqhelekileyo, "i-orange" iya kubonakala."Ulusu", "pitting" kunye nezinye iimeko.Emva koko, inkampani yethu iya kukuxelela indlela yokusombulula ingxaki "yokupholisa ngaphezulu" koomatshini bokupholisha ngokuzenzekelayo.

Xa i-workpiece yemveliso ibonakala "i-orange peel", ibangelwa ubukhulu becala bubushushu obugqithisileyo be-mold surface layer okanye i-carburization egqithisileyo.Xa ukunyanzeliswa kokusila kunye nokupholisa kukhulu kakhulu, ixesha lokusila kunye nokupholisa lide, nto leyo eya kubangela ukubonakala kwezixhobo."I-Orange peel" imeko.Ke yintoni "i-orenji peel"?Oko kukuthi, umaleko womphezulu awuqhelekanga kwaye urhabaxa.Ipleyiti yentsimbi elukhuni ngokwentelekiso iyakwazi ukumelana noxinzelelo lokusila kunye nokupholisha ubukhulu becala, kwaye ipleyiti yentsimbi ethambileyo ethambileyo ithandwa kakhulu ekusileni nasekupolisweni.

Ngoko ke, indlela yokuphelisa "i-orange peel" yomsebenzi wemveliso?Kufuneka kuqala sisuse umaleko womphezulu osisiphene, kwaye ke ubungakanani benkozo yokusila burhabaxa kancinane kunenani lesanti esetyenzisiweyo ngaphambili, kwaye sinciphise ubushushu bokucima ngama-25 ℃, kwaye ke uxinzelelo luyenziwa.Coca, emva koko sebenzisa isikhunta esinenombolo yesanti ecolekileyo ukupolisha, kwaye emva koko upholise ngamandla okukhanya kude kube umphumo uyanelisa.

Okubizwa ngokuba "yi-pitting" kukubonakala kwemigodi efana nechaphaza kwi-workpiece yemveliso emva kokupholisa.Oku kungenxa yokuba ezinye iintsalela zokungacoceki ezingezizo ezentsimbi ziya kuxutywa kwiimveliso zentsimbi, ezidla ngokuba zii-oksidi eziqinileyo kunye ne-brittle.Ukuba uxinzelelo lokupholisha luphezulu kakhulu okanye ixesha lokupholisha lide kakhulu, oku kungcola kunye neentsalela ziya kutsalwa ngaphandle kwi-surface layer yepleyiti yensimbi engenasici, yenze i-dot-like micro-pits.Ngokukodwa xa ukucoceka kweplate yensimbi engenasici akwanelanga kwaye umxholo we-residu yokungcola okunzima kuphezulu;umaleko womphezulu wepleyiti yentsimbi egqwethiweyo kwaye ugqwalile okanye ulusu olumnyama alucocwanga, "i-pitting corrosion" inokwenzeka ngakumbi.

Indlela yokuphelisa imeko "ye-pitting"?Umaleko womphezulu womsebenzi wemveliso upholiswa kwakhona.Ubungakanani beenkozo zesanti yokungunda esetyenzisiweyo yinqanaba elinye elirhabaxa kunelo lalisetyenziswa ngaphambili, kwaye amandla okugudisa kufuneka abe mancinci.Kwixesha elizayo, sebenzisa i-oilstones ethambileyo kwaye ebukhali kumanyathelo okupolisha alandelayo, kwaye emva koko wenze iinkqubo zokupolisha emva kokufumana iziphumo ezanelisayo.Xa umatshini wokupholisa ngokuzenzekelayo upholisa, ukuba ubungakanani begrit bungaphantsi kwe-1 mm, kuyimfuneko ukukhusela ukusetyenziswa kwezixhobo zokuthambisa ezithambileyo.Ukuqina kokugaya kunye nokupolisha kufuneka kube kuncinci kunokwenzeka, kwaye ixesha kufuneka libe lifutshane kangangoko.
