Ulwelo lokusika lulwelo lwemizi-mveliso olusetyenziselwa ukupholisa kunye nokuthambisa izixhobo kunye nezinto zokusebenza ngexesha lokusika isinyithi kunye nokusila.
Uhlobo lokusika ulwelo
Ulwelo lokusika olusekwe kumanzi lunokwahlulwa lube yi-emulsion, i-semi synthetic cutting fluid kunye ne-synthetic cutting fluid. I-diluent ye-emulsion inobisi olumhlophe ngenkangeleko; I-diluent ye-semi synthetic solution ikholisa ukuguquguquka, kwaye ezinye iimveliso zimhlophe qhwa; I-diluent yesisombululo sokwenziwa ngokuqhelekileyo ibonakala ngokucacileyo, njengamanzi okanye umbala omncinci.
Umsebenzi wokusika ulwelo
1. Ukuthambisa
Isiphumo sokuthambisa sesinyithi sokusika ulwelo kwinkqubo yokusika inokunciphisa ukungqubana phakathi kobuso beraki kunye neechips, kwaye phakathi kobuso obungasemva kunye nomgangatho owenziwe ngomatshini, ukwenza ifilimu yokuthambisa inxalenye, ngaloo ndlela ukunciphisa amandla okusika, ukungqubana kunye nokusetyenziswa kwamandla, ukunciphisa. ubushushu bomphezulu kunye nokunxiba kwesixhobo senxalenye yokukhuhlana phakathi kwesixhobo kunye nesixhobo sokusebenza esingenanto, kunye nokuphucula ukusebenza kokusika kwesixhobo sokusebenza.
2. Ukupholisa
Umphumo wokupholisa wokusika ulwelo kukuthatha ubushushu bokusika kude nesixhobo kunye ne-workpiece ngokusebenzisa i-convection kunye ne-vaporization phakathi kwayo kunye nesixhobo, i-chip kunye ne-workpiece eshushu ngokusika, ukwenzela ukunciphisa ngokufanelekileyo ubushushu bokusika, ukunciphisa ukuguqulwa kwe-thermal deformation. workpiece kunye nesixhobo, ukugcina ubulukhuni isixhobo, nokuphucula ukuchaneka machining kunye nokuqina isixhobo.
3. Ukucoca
Kwinkqubo yokusika isinyithi, ukusika ulwelo olufunekayo ukuze ube nefuthe elihle lokucoca. Susa ii-chips eziveliswayo, ii-chips ze-abrasive, i-iron powder, ukungcola kweoli kunye neengqungquthela zesihlabathi, ukuthintela ukungcoliswa kwezixhobo zoomatshini, izixhobo zokusebenza kunye nezixhobo, kwaye ugcine umgca wokusika izixhobo okanye amavili okugaya abukhali ngaphandle kokuchaphazela umphumo wokusika.
4. Ukuthintela umhlwa
Kwinkqubo yokusika isinyithi, i-workpiece iya kutshatyalaliswa ngokuqhagamshelana nemithombo yeendaba ebolileyo efana ne-oyile ye-sludge eyenziwa ngokubola okanye ukuguqulwa kwe-oxidative yemithombo yeendaba engqongileyo kunye nezixhobo zokusika ulwelo, kunye nomphezulu wezixhobo zomatshini ezithintana nolwelo lokusika nazo ziya kugqwala. .
Idatha eyandisiweyo
Umahluko phakathi kolwelo oluhlukeneyo lokusika
Isiseko se-oyile sokusika ulwelo lunokusebenza kakuhle kokuthambisa kunye nesiphumo esibi sokupholisa. Xa kuthelekiswa nolwelo lokusika olusekwe kwi-oyile, ulwelo lokusika olusekwe kumanzi lunomgangatho ophantsi wokuthambisa kunye nesiphumo esingcono sokupholisa. Ukusika kancinci kufuna ukuthambisa okuqinileyo kolwelo lokusika. Ngokuqhelekileyo, ioli yokusika isetyenziswe xa isantya sokusika singaphantsi kwe-30m / min.
Ioli yokusika equlethe i-additive yoxinzelelo olugqithisileyo iyasebenza ukusika nayiphi na into xa isantya sokusika singadluli kwi-60m / min. Ngexesha lokusika kwesantya esiphezulu, ngenxa yesizukulwana esikhulu sokushisa kunye nefuthe elibi lokutshintshwa kwe-oyile-based based cutting fluid, ukushisa kwindawo yokusika kuya kuba phezulu kakhulu, okuya kubangela umsi, umlilo kunye nezinye izinto kwioli yokusika. Ukongezelela, ngenxa yokuba iqondo lokushisa liphezulu kakhulu, i-thermal deformation iya kwenzeka, eya kuchaphazela ukuchaneka kwe-machining ye-workpiece, ngoko ke i-water-based cutting cutting isetyenziswe ngakumbi.
I-Emulsion idibanisa i-lubricity kunye ne-rust resistance ye-oyile kunye nepropati epholileyo yokupholisa kwamanzi, kwaye ine-lubricity elungileyo kunye nepropati yokupholisa, ngoko iyasebenza kakhulu ukusika isinyithi ngesantya esiphezulu kunye noxinzelelo oluphantsi oluveliswa ngumlinganiselo omkhulu wokushisa. Xa kuthelekiswa ne-oil-based cutting cutting fluid, iingenelo ze-emulsion zilele ekugqithiseni ukushisa okukhulu, ukucoceka, kunye noqoqosho ngenxa yokuhlanjululwa ngamanzi.
