I-1.I-Mechanical polishing I-polish yomatshini yindlela yokupholisa esusa iindawo ze-convex ezikhazimlisiweyo ngokusika kunye nokuguqulwa kweplastiki yendawo yempahla ukuze kufumaneke indawo egudileyo.Ngokubanzi, imicu ye-oilstone, amavili oboya, i-sandpaper, njl. njl isetyenziselwa iimfuno zomgangatho ophezulu womphezulu.I-Ultra-precision yokusila kunye ne-polish sisixhobo esikhethekileyo sokuqhaqhaqha, esicinezelwe phezu kwendawo yokusebenza ukuba ifakwe kumatshini wokusila kunye ne-polish liquid equkethe i-abrasive, kwaye ijikeleza ngesantya esiphezulu.Ukusebenzisa le teknoloji, uburhabaxa bomphezulu beRa0.008μm bunokufezekiswa, eyona nto iphezulu phakathi kweendlela ezahlukeneyo zokupolisha.Ii-lens ze-Optical molds zihlala zisebenzisa le ndlela.
Ngokucacileyo amavili ehemp athengiswa yinkampani asetyenziselwa olu hlobo lokupolisha, ikakhulu ukupolisha okuphakathi kwentsimbi engatyiwayo.
I-2.I-Chemical polishing I-Chemical polishing kukuvumela ukuba iinxalenye ze-microscopically eziphuma kwizinto eziphathekayo kwindawo yeekhemikhali ukuba zinyibilike ngokukhethekileyo kwiindawo ze-concave, ngaloo ndlela zifumana indawo egudileyo.Eyona nzuzo iphambili yale ndlela kukuba ayifuni izixhobo ezintsonkothileyo, inokupolisha izixhobo zokusebenza ezinemilo entsonkothileyo, kwaye inokupholisha uninzi lwemisebenzi ngaxeshanye, ngokusebenza okuphezulu.Ingxaki engundoqo yokupholisa imichiza kukulungiswa kolwelo lokupholisha.Uburhabaxa bomphezulu obufunyenwe ngokugudiswa kweekhemikhali ngokuqhelekileyo zii-10 μm ezininzi.
I-3.I-Electrolytic polishing Umgaqo osisiseko we-electrolytic polishing ufana nowokupholisa imichiza, oko kukuthi, ngokukhetha ngokukhetha iiprotrusions ezincinci kumphezulu wezinto eziphathekayo ukuze wenze umphezulu ube lula.Xa kuthelekiswa nokupholisa imichiza, impembelelo ye-cathode reaction inokupheliswa, kwaye umphumo ungcono.Inkqubo yokupolisha ye-electrochemical yahlulwe ngamanyathelo amabini: (1) Ukuthambisa ngokucokisekileyo iimveliso ezinyibilikisiweyo kwaye zisasazeke kwi-electrolyte, uburhabaxa bejometri bomphezulu wezinto buyahla, kunye neRa> 1μm.(2) I-anodic polarization ithotywe ngokukhanya okuphantsi, kwaye ukukhanya komphezulu kuphuculwe, kwaye uRa<1μm<br /> 4.Kwi-ultrasonic polishing, i-workpiece ifakwe kwi-abrasive suspension kwaye ifakwe kwintsimi ye-ultrasonic kunye, kwaye i-abrasive iphantsi kwaye iphuculwe phezu kwendawo yokusebenza nge-oscillation ye-ultrasonic wave.I-macroscopic force ye-ultrasonic processing incinci, kwaye ayiyi kubangela i-deformation ye-workpiece, kodwa kunzima ukwenza kunye nokufaka izixhobo zokusebenza.I-ultrasonic machining inokudibaniswa kunye neendlela zeekhemikhali okanye ze-electrochemical.Ngesiseko se-corrosion yesisombululo kunye ne-electrolysis, i-vibration ye-ultrasonic isetyenziselwa ukuvuselela isisombululo, ukwenzela ukuba iimveliso ezichithwe kumphezulu we-workpiece zivaliwe, kwaye i-corrosion okanye i-electrolyte kufuphi nomphezulu ifana;i-cavitation yamaza e-ultrasonic kwi-liquid nayo inokuthintela inkqubo ye-corrosion, ehambelana nokukhanya kwendawo.
5.I-Fluid polishing I-Fluid polishing ixhomekeke kulwelo oluhamba ngesantya esiphezulu kunye namasuntswana abrasive athwalwa yiyo ukukhuhla umphezulu we-workpiece ukufezekisa injongo yokupolisha.Iindlela ezisetyenziswa ngokuqhelekileyo zezi: i-abrasive jet machining, i-jet machining ye-liquid, i-hydrodynamic grinding, njl.I-medium yenziwe ngokukodwa kwiikhompawundi ezikhethekileyo (izinto ezinjenge-polymer) kunye nokuhamba kakuhle phantsi koxinzelelo oluphantsi kwaye ixutywe kunye ne-abrasives, kunye ne-abrasives ingaba yi-silicon carbide powder.
6.Imagnethi yokusila kunye nokupholisha Ukusila kunye nokupholisha iMagnetic kukusetyenziswa kwe-abrasives magnetic ukwenza iibrashi ezirhaxayo phantsi kwesenzo somhlaba wemagnethi ukucola izinto zokusebenza.Le ndlela iphezulu yokusebenza kakuhle, umgangatho omhle, ulawulo olulula lweemeko zokucubungula kunye neemeko ezilungileyo zokusebenza.Ngama-abrasives afanelekileyo, uburhabaxa bomphezulu bunokufikelela kwiRa0.1μm.
