Undoqo kunye nokuphunyezwa kokupholisha
Kutheni le nto kufuneka siqhube umphezulu womsebenzi kumalungu oomatshini?
Inkqubo yonyango yomphezulu iya kuhluka ngeenjongo ezahlukeneyo.
1 Iinjongo ezintathu zokusetyenzwa komphezulu wamalungu oomatshini:
1.1 Indlela yokulungisa umphezulu wokufumana ukuchaneka kwenxalenye
Kwiindawo ezineemfuno zokutshatisa, iimfuno zokuchaneka (kubandakanya ukuchaneka kobukhulu, ukuchaneka kwemilo kunye nokuchaneka kwendawo) zidla ngokuba phezulu, kwaye ukuchaneka kunye noburhabaxa bomphezulu ziyahambelana.Ukufumana ukuchaneka, uburhabaxa obuhambelanayo kufuneka buphunyezwe.Umzekelo: ukuchaneka kwe-IT6 ngokubanzi kufuna uburhabaxa obuhambelana neRa0.8.

2 Itekhnoloji yokugulisa ubuso besinyithi
2.1 Ukubaluleka Kuyingxenye ebalulekileyo yecandelo lobugcisa bomhlaba kunye nobunjineli, kwaye isetyenziswa ngokubanzi kwiinkqubo zokuvelisa i-industrial, ngokukodwa kwi-industry ye-electroplating, i-coating, i-anodizing kunye neenkqubo ezahlukeneyo zokunyanga komhlaba.
2.2 Kutheni le nto iiparamitha zomphezulu wokuqala kunye neeparamitha zesiphumo esiphunyeziweyo somsebenzi womsebenzi zibaluleke kangaka?Ngenxa yokuba zizinto zokuqala kunye nezijoliswe kuzo zomsebenzi wokupolisha, omisela indlela yokukhetha uhlobo lomatshini wokupolisha, kunye nenani leentloko zokusila, uhlobo lwezinto eziphathekayo, iindleko, kunye nokusebenza kakuhle okufunekayo kumatshini wokupolisha.
2.3 Amanqanaba okuSila kunye nokumenyezwa kunye neeTrajectories
Izigaba ezine eziqhelekileyo zeukusilakwayeukupolisha ] : ngokwe-roughness yokuqala neyokugqibela Ra values of the workpiece, coarse grinding - fine grinding - fine grinding - polishing.Iibrasives ziqala ngokurhabaxa ukuya kwehle.Isixhobo sokugaya kunye nomsebenzi kufuneka zicocwe rhoqo xa zitshintshwa.
2.3.1 Isixhobo sokugaya sinzima, i-micro-cutting kunye ne-extrusion effect inkulu, kwaye ubukhulu kunye nobunzima bunotshintsho olucacileyo.
2.3.2 Ukupholisha koomatshini yinkqubo yokusika ecekethekileyo kunokusila.Isixhobo sokupholisa senziwe ngezinto ezithambileyo, ezinokunciphisa kuphela uburhabaxa kodwa azikwazi ukutshintsha ukuchaneka kobukhulu kunye nokuma.Uburhabaxa bunokufikelela ngaphantsi kwe-0.4μm.
2.4 Iikhonsepthi ezintathu zokulungiswa komphezulu wokugqiba: ukucola, ukupholishela kunye nokugqiba
2.4.1 Ingcamango yokusila ngoomatshini kunye nokupholisha
Nangona zombini ukucola koomatshini kunye nokupolishwa ngoomatshini kunokunciphisa uburhabaxa bomphezulu, kukwakho umahluko:
- 【Mechanical polishing】: Ibandakanya ukunyamezela idimensional, ukunyamezela imilo kunye nokunyamezela isikhundla.Kufuneka iqinisekise ukunyamezelwa kwe-dimensional, ukunyamezela imilo kunye nokunyamezela isikhundla somhlaba ophantsi ngelixa unciphisa uburhabaxa.
- Ukupholisha koomatshini: Kwahlukile ekupholiseni.Iphucula kuphela ukugqitywa komphezulu, kodwa ukunyamezela akukwazi ukuqinisekiswa ngokuthembekileyo.Ukukhanya kwayo kuphezulu kwaye kuqaqambile kunokumenyezeliswa.Indlela eqhelekileyo yokupolisha ngoomatshini kukugaya.
2.4.2 [Ukugqiba ukucutshungulwa] yinkqubo yokusila kunye nokupolisha (efinyeziweyo njengokusila kunye nokupholisha) oqhutyelwa kwi-workpiece emva kokulungiswa kakuhle, ngaphandle kokususa okanye ukususa kuphela umaleko omncinci kakhulu wezinto eziphathekayo, ngenjongo ephambili yokunciphisa uburhabaxa bomhlaba, ukwandisa iglosi yomphezulu kunye nokomeleza umphezulu wayo.
Ukuchaneka kunye noburhabaxa benxalenye yomhlaba kunempembelelo enkulu kubomi bayo kunye nomgangatho.Uluhlu olubi olushiywe yi-EDM kunye neengqungquthela ezincinci ezishiywe ngokusila ziya kuchaphazela ubomi benkonzo yamacandelo.
① Inkqubo yokugqiba inesibonelelo esincinci somatshini kwaye isetyenziselwa ukuphucula umgangatho ophezulu.Isixa esincinci sisetyenziselwa ukuphucula ukuchaneka komatshini (njengokuchaneka kwe-dimensional kunye nokuchaneka kwemilo), kodwa ayinakusetyenziselwa ukuphucula ukuchaneka kwendawo.
② Ukugqiba yinkqubo yokusika kunye nokukhupha i-workpiece surface kunye ne-abrasives ecocekileyo.Umphezulu ucutshungulwa ngokulinganayo, amandla okusika kunye nokushisa okusika kuncinci kakhulu, kwaye umgangatho ophezulu kakhulu unokufumaneka.③ Ukugqiba yinkqubo yokwenziwa kwezinto ezincinci kwaye ayikwazi ukulungisa iziphene ezinkulu.Ukusetyenzwa kakuhle kufuneka kwenziwe phambi kokulungiswa.
Undoqo wokupholishwa komphezulu wesinyithi kukusetyenzwa komphezulu okukhethiweyo kokususa izinto ezincinci.
3. Iindlela zenkqubo yokupolisha ngoku esele zikhulile: 3.1 ukupolisha ngoomatshini, 3.2 ukupholishwa kweekhemikhali, 3.3 ukupholishwa kwe-electrolytic, 3.4 ukupolisha ngeultrasonic, 3.5 ukupolisha ulwelo, 3.6 ukugulisa magnetic,
3.1 Ukuguliswa koomatshini
I-polish ye-Mechanical yindlela yokupholisa exhomekeke ekusikeni kunye nokuguqulwa kweplastiki yendawo yezinto eziphathekayo ukususa iiprotrusions eziphuculweyo ukuze kufumaneke indawo egudileyo.
Ukusebenzisa le teknoloji, ukupolisha ngoomatshini kunokufikelela kubunzima obuphezulu be-Ra0.008μm, eyona iphakamileyo phakathi kweendlela ezahlukeneyo zokupolisha.Le ndlela isoloko isetyenziswa kwi-optical lens molds.
3.2 Ukuguliswa kweekhemikhali
Ukupholiswa kwemichiza kukwenza iinxalenye zeconvex ezincanyana zomphezulu wemathiriyeli zinyibilike ngokukhethekileyo kumbindi wekhemikhali ngaphezulu kweendawo ezigobileyo, ukuze kufumaneke indawo egudileyo.Iingenelo eziphambili zale ndlela kukuba ayifuni zixhobo ezintsonkothileyo, inokupolisha izixhobo zokusebenza ezinemilo entsonkothileyo, inokupolisha izixhobo zokusebenza ezininzi ngaxeshanye, kwaye isebenza kakuhle kakhulu.Umba ongundoqo wokupholisa imichiza kukulungiswa kolwelo lokupholisha.Uburhabaxa bomphezulu obufunyenwe ngokugudiswa kweekhemikhali ngokuqhelekileyo bumashumi aliqela e-μm.
3.3 Ukuguliswa kwe-Electrolytic
I-Electrolytic polishing, ekwabizwa ngokuba yi-electrochemical polishing, ngokukhetha inyibilikisa iiprotrusions ezincinci kumphezulu wesixhobo ukwenza umphezulu ube mtyibilizi.
Xa kuthelekiswa nokupolisha kweekhemikhali, umphumo we-cathode reaction unokupheliswa kwaye umphumo ungcono.Inkqubo ye-electrochemical polishing yahlulwe yangamanyathelo amabini:
(1) I-Macro-leveling: Iimveliso ezinyibilikileyo zisasazeka kwi-electrolyte, kwaye uburhabaxa bejometri yezinto eziphathekayo buyancipha, i-Ra 1μm.
(2) Ukugudiswa kweglosi: I-Anodic polarization: Ukuqaqamba komphezulu kuphuculwe, iRalμm.
3.4 I-Ultrasonic polishing
I-workpiece ifakwe kwi-abrasive suspension kwaye ifakwe kwintsimi ye-ultrasonic.I-abrasive iphantsi kwaye ipholishelwe kwindawo yokusebenza nge-oscillation ye-ultrasonic wave.I-ultrasonic machining ine-force encinci ye-macroscopic kwaye ayiyi kubangela i-deformation ye-workpiece, kodwa i-tooling inzima ukwenza kunye nokuyifaka.
I-ultrasonic machining inokudibaniswa kunye neendlela zeekhemikhali okanye ze-electrochemical.Ngesiseko se-corrosion yesisombululo kunye ne-electrolysis, i-vibration ye-ultrasonic isetyenziselwa ukuvuselela isisombululo sokuhlukanisa iimveliso ezichithwe kwindawo yokusebenza kunye nokwenza i-corrosion okanye i-electrolyte kufuphi neyunifomu yomhlaba;i-cavitation effect yamaza e-ultrasonic kwi-liquid nayo inokuthintela inkqubo ye-corrosion kwaye iququzelele ukukhanya kwendawo.
3.5 Ukupholisha ulwelo
Ukupholishwa kolwelo kuxhomekeke kulwelo olubalekayo oluhamba ngesantya esiphezulu kunye namasuntswana abrasive aluthwalayo ukubrasha umphezulu womsebenzi ukufezekisa injongo yokupholisha.
Iindlela ezisetyenziswa ngokuqhelekileyo ziquka: i-abrasive jet processing, i-liquid jet processing, i-fluid dynamic grinding, njl.
3.6 Ukusila ngemagnethi nokupholisha
Ukusila ngemagnethi kunye nokupholisha kusebenzisa izitshixo ezinozibuthe ukwenza iibhrashi ezirhabaxa phantsi kwentshukumo yemagnethi yokusila umsebenzi.
Le ndlela iphezulu yokusebenza kakuhle, umgangatho olungileyo, ulawulo olulula lweemeko zokusebenza, kunye neemeko ezilungileyo zokusebenza.Ngama-abrasives afanelekileyo, uburhabaxa bomphezulu bunokufikelela kwiRa0.1μm.
Ngeli nqaku, ndiyakholelwa ukuba uya kuba nokuqonda okungcono kokupholisha.Iindidi ezahlukeneyo zoomatshini bokupholisha ziya kugqiba umphumo, ukusebenza kakuhle, iindleko kunye nezinye izikhombisi zokufikelela kwiinjongo ezahlukeneyo zokupholisha.
Luhlobo luni lomatshini wokupolisha inkampani yakho okanye abathengi bakho kufuneka bangahambelani kuphela ngokuhambelana nomsebenzi ngokwawo, kodwa ngokusekwe kwimfuno yemarike yomsebenzisi, imeko yezemali, uphuhliso lweshishini kunye nezinye izinto.
Ewe, kukho indlela elula nesebenzayo yokujongana nale nto.Nceda udibane nabasebenzi bethu bangaphambi kokuthengisa ukuze bakuncede.
