(1) Mechanical polishing

Mechanical polishing bụ usoro polishing nke a na-enweta elu dị mma site na ịkpụ na nrụrụ plastik nke elu nke ihe ahụ iji wepụ akụkụ convex a na-egbuke egbuke.N'ozuzu, a na-eji ibe nkume whetstone, wiil ajị anụ, akwụkwọ aja, wdg.Iji ngwá ọrụ inyeaka dị ka turntables, ultra-mma egweri na polishing ụzọ nwere ike iji maka ndị nwere elu elu mma chọrọ.Ultra-nkenke egweri na polishing bụ ihe pụrụ iche abrasive ngwá ọrụ, nke a na-enwe n'elu nke workpiece ka machined na-egweri na polishing mmiri mmiri nwere abrasive, na-atụgharị na elu na-agba.N'iji teknụzụ a, enwere ike nweta oke ike nke Ra0.008μm, nke kachasị elu n'etiti ụzọ polishing dị iche iche.Igwe anya lens na-ejikarị usoro a

(2) Ultrasonic polishing

A na-etinye workpiece na nkwusioru abrasive ma tinye ya na mpaghara ultrasonic ọnụ, na abrasive bụ ala ma na-egbuke egbuke n'elu nke workpiece site na oscillation nke ultrasonic ife.Ike macroscopic nke ultrasonic nhazi dị ntakịrị, ọ gaghịkwa eme ka nrụrụ nke workpiece, ma ọ siri ike ịme ma wụnye ngwá ọrụ.Enwere ike ijikọ machining ultrasonic na usoro kemịkalụ ma ọ bụ electrochemical.Na ndabere nke ngwọta corrosion na electrolysis, ultrasonic vibration na-etinye aka ịkpali ihe ngwọta, nke mere na etisasịwo ngwaahịa n'elu nke workpiece na-wepụrụ, na corrosion ma ọ bụ electrolyte nso n'elu bụ edo;mmetụta cavitation nke ebili mmiri ultrasonic na mmiri mmiri nwekwara ike igbochi usoro mmebi ahụ, nke na-eme ka ọ dịkwuo elu.
