Habka nadiifinta ee caaryada caaga ah

Daalidda makaanikada

Daalida makaanikadu waa hab biliish ah oo ku tiirsan goynta iyo qalloocinta balaastiigga ah ee dusha walxaha si looga saaro qaybaha convex ee la dabciyay si loo helo dusha siman.Guud ahaan, alwaaxyada dhagaxa saliidda, dhogorta dhogorta, xaashida ciidda, iwm. ayaa la isticmaalaa, hawlgallada gacanta ayaa ah habka ugu muhiimsan.Qaybo gaar ah sida dusha sare ee jirka wareega ayaa la isticmaali karaa.Isticmaalka qalabka caawinta sida weel-wareejinta, suufka saxda ah ee saxda ah ayaa loo isticmaali karaa kuwa leh shuruudaha tayada sare ee dusha sare.Tooshka saxda ah ee saxda ah waa isticmaalka qalab gaar ah oo xoqaya, kuwaas oo si adag loogu cadaadiyo dusha la warshadeeyay ee shaqada ee dareeraha polishing ee ka kooban nabarrada wareegga xawaaraha sare leh.Isticmaalka tignoolajiyadan, qallafsanaanta dusha sare ee Ra0.008μm ayaa lagu gaari karaa, taas oo ah tan ugu sareysa ee hababka polishing ee kala duwan.Caaryada muraayadaha indhaha ayaa inta badan isticmaala habkan.

Daalida kiimikada

Daalidda kiimikadu waa in la sameeyo qayb ka mid ah convex microscopic oo ka mid ah walaxda dhexdhexaadka ah ee kiimikaad in ay milaan si ka doorbidan qaybta concave, si loo helo dusha siman.Faa'iidada ugu weyn ee habkan ayaa ah in aysan u baahnayn qalab adag, waxay nadiifin kartaa qalabka shaqada ee qaababka adag, oo ay ku nadiifin karaan qaybo badan oo shaqo isku mid ah, oo leh waxtar sare.Dhibaatada udub dhexaad u ah nadiifinta kiimikada waa diyaarinta dareeraha dhalaalaysa.Qalafsanaanta dusha sare ee lagu helo nadiifinta kiimikada guud ahaan waa dhowr 10 μm.

Daalidda Electrolytic

Mabda'a aasaasiga ah ee polishing electrolytic waxay la mid tahay tan kiimikaad polishing, taas oo ah, iyada oo la dooranayo kala dirida soo-baxyada yaryar ee dusha sare ee alaabta si ay dusha uga dhigto mid siman.Marka la barbardhigo nadiifinta kiimikada, saameynta falcelinta cathode waa la baabi'in karaa, saameyntuna way ka fiican tahay.Habka dhalaalidda korantada ee korantada waxa loo qaybiyaa laba tillaabo: (1) Heerarka makroscopic Alaabooyinka kala diri waxay ku kala dareeraan korantada, iyo qallafsanaanta joomatari ee dusha maaddada ayaa hoos u dhacda, Ra> 1μm.⑵ Heerka iftiinka-hooseeya: polarization anode, dhalaalka dusha sare waa la wanaajiyey, Ra <1μm.

Daalidda Ultrasonic

Geli workpiece in ganaax naxaas ah oo isku geeyey beerta ultrasonic, ku tiirsan saamaynta oscillation ee ultrasonic ah, si abrasive waa dhulka iyo turub dusha workpiece ah.Mashiinka ultrasonic wuxuu leeyahay awood yar oo makroscopic ah mana keeni doono qallafsanaanta qalabka shaqada, laakiin way adag tahay in la soo saaro oo la rakibo qalabka.Ka-hortagga Ultrasonic waxaa lagu dari karaa hababka kiimikada ama kiimikooyinka.Iyada oo ku saleysan daxalka xalka iyo electrolysis, gariir ultrasonic waxaa lagu dabaqaa si loo kiciyo xalka, si alaabooyinka kala diri dusha sare ee workpiece ay kala soocaan, iyo daxalka ama electrolyte u dhow dusha sare waa lebis;Saamaynta cavitation ee ultrasonic ee dareeraha ayaa sidoo kale joojin kara habka daxalka iyo fududaynta iftiinka dusha sare.

Dareemidda dareeraha

Daalidda dareeraha waxay ku tiirsan tahay dareeraha qulqulaya xawaaraha sare leh iyo qaybo xoqan oo ay sido si ay u dhaqdo dusha sare ee qalabka shaqada si loo gaaro ujeedada dhalaalidda.Hababka caadiga ah ee la isticmaalo waa: farsamaynta jetka abrasive, farsamaynta jet dareeraha, shiidi hydrodynamic iyo wixii la mid ah.Shiididda Hydrodynamic waxaa kaxeeya cadaadiska Haydarooliga si ay u sameeyaan dhexdhexaadinta dareeraha ah ee sidda walxaha xoqan ee dib iyo dib ugu qulqulaya dusha sare ee workpiece xawaare sare leh.Dhexdhexaadku wuxuu inta badan ka samaysan yahay xeryahooda gaarka ah (walxaha polymer u eg) oo leh socodka wanaagsan ee cadaadiska hoose oo lagu qaso nabarrada.Abrasives-yada waxaa laga samayn karaa budada carbide silicon.

Shiididda iyo turxaan bixinta magnetka

Naaxinta birlababka birlabeedka waa in la isticmaalo nabarrada birlabka si ay u sameeyaan burush abrasive ah oo hoos timaadda falgalka birlabeedka si loo shiiddo qaybta shaqada.Habkani waxa uu leeyahay waxtarka processing sare, tayada wanaagsan, xakamaynta fudud ee xaaladaha processing iyo xaaladaha shaqada wanaagsan.Isticmaalka abrasives ku habboon, qallafsanaanta dusha sare waxay gaari kartaa Ra0.1μm.2 Daahfurka makaanikada ee ku salaysan habkan Daahfurka lagu sheegay habaynta caaryada caagga ah aad ayuu uga duwan yahay dhalaalidda dusha sare ee looga baahan yahay warshadaha kale.Si adag u hadla, nadiifinta caaryada waa in lagu magacaabaa farsamaynta muraayadda.Ma aha oo kaliya inay leedahay shuruudo sare oo loogu talagalay istaahilinta lafteeda, laakiin sidoo kale waxay leedahay heerar sare oo loogu talagalay fidsanaanta dusha sare, simanaanta iyo saxnaanta joomatari.Naaxinta dusha sare waxay guud ahaan u baahan tahay oog dhalaalaysa.Halbeegga farsamaynta dusha muraayadda waxa loo qaybiyaa afar heer: AO=Ra0.008μm, A1=Ra0.016μm, A3=Ra0.032μm, A4=Ra0.063μm.Way adag tahay in si sax ah loo xakameeyo saxnaanta joomatari ee qaybaha iyadoo ay ugu wacan tahay hababka ay ka midka yihiin polishing electrolytic iyo polishing dareere.Si kastaba ha ahaatee, tayada dusha sare ee polishing kiimikada, polishing ultrasonic, polishing abrasive magnetic iyo hababka kale ma aha ilaa shuruudaha, sidaa darteed farsamaynta muraayadda ee caaryada saxda ah ayaa weli inta badan polishing farsamada.
