Iingenelo kunye nokungalungi kwezixhobo zokugaya idayimani ezifakwe ngombane Umahluko phakathiiipadi zokugquma idayimani ezifakwe ngombanekunye nezixhobo zokugaya idayimani yeresin
Isixhobo sokugquma idayimani esifakwe ngombane sisixhobo sokugquma idayimani esenziwe ngendlela ye-electrochemical. Umaleko osebenzayo wesixhobo sokugquma uqulathe amasuntswana agquma idayimani, kwaye i-diamond abrasive ibotshelelwe kwi-substrate nge-metal bond. Okokuqala, ubukhulu be-metal bond yi-20% yokuphakama kwee-diamond abrasive grains (sanding), kwaye emva koko ii-diamond abrasive grains zibotshelelwe (zijiyile) nge-metal bond, kwaye ubukhulu bumalunga ne-2/3 yokuphakama kwee-abrasive grains. Kubandakanya izixhobo zokugquma idayimani, izixhobo zedayimani zokusila okanye zokusika.
Iingenelo zezixhobo ze-abrasive zedayimani ezifakwe ngombane
①Inkqubo yokufakelwa kwe-electroplating ilula, utyalo-mali luphantsi, kwaye ukwenziwa kwayo kulula;
②Akukho mfuneko yokucheba, kulula ukuyisebenzisa;
③Isakhiwo esinomgangatho omnye sigqiba ekubeni singafikelela kwisantya esiphezulu sokusebenza, okwangoku esifikelela kwi-250-300m/s kwamanye amazwe;
④Nangona kukho umaleko omnye wedayimani, isenobomi obaneleyo;
⑤ Kwizixhobo ezirhabaxa ezineemfuno ezichanekileyo, i-electroplating yeyona ndlela yokuvelisa kuphela.
Ngenxa yezi nzuzo, ukugaywa kwe-abrasives ezifakwe ngombane ngesantya esiphezulu nangesantya esiphezulu kuthatha indawo ebalaseleyo engenakuphikiswa.
Iziphene kwi-electroplated diamond abrasives
Akukho khonkco liqinileyo le-metallurgical phakathi kwesinyithi esigqumayo kunye ne-substrate kunye nomphezulu wokubopha orhabaxa. I-abrasive eneneni ifakwe kuphela ngoomatshini kwaye igqunywe ngesinyithi esigqumayo, ngoko ke amandla okubamba mancinci, kwaye amasuntswana edayimani aphantsi komthwalo onzima. ) kwaye kukhokelela ekusileleni ngokupheleleyo; ukuze kwandiswe amandla okubamba, ubukhulu bengubo kufuneka bunyuswe, ngenxa yoko, ukuphakama okubonakalayo kwamasuntswana arhabaxa kuyancitshiswa, indawo yetshiphu iyancitshiswa, isixhobo esirhabaxa sithambekele ekuvalekeni, isiphumo sokusasazwa kobushushu asilunganga, kwaye umphezulu wento yokusebenza uthambekele ekutshisweni. Okwangoku, imveliso yezixhobo ezirhabaxa ze-electroplating zasekhaya ayikafumani uyilo olufanelekileyo lwe-topography engcono yezixhobo zokusila ngokweemeko zokucubungula.
Umahluko phakathi kwezixhobo zokugaya idayimani ye-resin kunye nezixhobo zokugaya idayimani nge-electroplating
Ngenxa yomahluko kwi-binder, isixhobo se-resin diamond abrasive sisebenzisa kakhulu i-phenolic resin kunye nomgubo omncinci wesinyithi njenge-binder, ngelixa isixhobo se-diamond abrasive esenziwe nge-electroplated luhlobo lwezixhobo zokusila ezibeka i-nickel-cobalt alloy kumphezulu we-substrate yesinyithi kwaye zilungise i-diamond abrasive ngendlela ye-electrodeposition. Inkqubo yemveliso, umahluko ophambili ekusebenzeni kwazo zezi:
1. Ngokuphathelele ukusebenza kakuhle kokucubungula, ekubeni ii-abrasives ezifakwe ngombane zisebenzisa ii-abrasives zodidi oluphezulu kwaye zinomgangatho omnye kuphela we-abrasives, zineengenelo zazo ngokubhekiselele ekusebenzeni kokusasaza ubushushu, njl.njl., ngoko ke ii-abrasives zedayimani ezifakwe ngombane zisebenza kakuhle kakhulu kokucubungula;
2. Ngokuphathelele ubomi benkonzo, ii-abrasives ezifakwe ngombane zinomaleko omnye kuphela we-abrasive, ngoko ke ubomi benkonzo yezixhobo zokugaya ezifakwe ngombane buya kuba ngaphantsi kobo be-resin diamond abrasives;
3. Ngokuphathelele ukuchaneka komatshini, uburhabaxa bomphezulu wesixhobo somsebenzi buchaphazeleka bubungakanani obufanayo besuntswana, kwaye uburhabaxa bomphezulu wesixhobo sokurhabaxa esenziwe nge-electroplated bumbi ngakumbi.
