Nzira yekupukuta yepurasitiki
Kupukuta kwemuchina
Kupukuta nemechanical inzira yekupukuta inoshandisa kucheka nekuchinja kwepurasitiki pamusoro pechinhu kuti ibvise zvikamu zvakaposhwa zvakapfava kuti pave nepamusoro pakanaka. Kazhinji, matanda ematombo emafuta, mavhiri emvere, sandpaper, nezvimwewo zvinoshandiswa, uye mashandiro emaoko ndiyo nzira huru. Zvikamu zvakakosha zvakaita sepamusoro pemuviri unotenderera zvinogona kushandiswa. Uchishandisa maturusi ekubatsira akadai sematurntable, kupukuta neunyanzvi hwepamusoro kunogona kushandiswa kune avo vane zvinodiwa zvepamusoro. Kupukuta neunyanzvi hwepamusoro ndiko kushandiswa kwezvishandiso zvakakosha zvekukwesha, izvo zvinodzvanywa zvakasimba pamusoro pechinhu chebasa chakagadziriswa mumvura inokwesha ine maabrasives ekutenderera nekukurumidza. Uchishandisa tekinoroji iyi, kugona kwepamusoro kweRa0.008μm kunogona kuwanikwa, inova ndiyo yepamusoro pakati penzira dzakasiyana dzekukwesha. Maoptical lens molds anowanzo shandisa nzira iyi.
Kupukuta kwemakemikari
Kupukuta nemakemikari kunoreva kuti pamusoro pechinhu chiri muchimiro chemakemikari chinyungudike kupfuura pamusoro pechinhu chakakombama, kuitira kuti pave nepamusoro pakanaka. Chinhu chikuru cheiyi nzira ndechekuti haidi michina yakaoma, inogona kupukuta maworkpieces ane maumbirwo akaomarara, uye inogona kupukuta maworkpieces akawanda panguva imwe chete, nekushanda kwakanyanya. Dambudziko guru rekupukuta nemakemikari nderekugadzirira mvura yekupukuta. Kuomarara kwepamusoro kunowanikwa nekupukuta nemakemikari kunowanzova 10 μm.
Kukwesha kwemagetsi
Nheyo huru yekupukuta nemagetsi yakafanana neyekupukuta nemakemikari, ndiko kuti, nekunyungudutsa zvidimbu zvidiki pamusoro pechinhu kuti pamusoro pacho pave pakanaka. Kana tichienzanisa nekupukuta nemakemikari, mhedzisiro ye cathode reaction inogona kubviswa, uye mhedzisiro yacho iri nani. Maitiro ekupukuta nemagetsi akakamurwa kuita matanho maviri: (1) Kuenzanisa nemagetsi. Zvigadzirwa zvakanyungudutswa zvinopararira mu electrolyte, uye kushata kwejometri kwenzvimbo yezvinhu kunoderera, Ra>1μm. ⑵ Kuenzanisa kwechiedza chakaderera: Anode polarization, kupenya kwepamusoro kunovandudzwa, Ra<1μm.
Kukwesha kweUltrasonic
Isa workpiece mu abrasive suspension woibatanidza pamwe chete mumunda we ultrasonic, uchivimba ne oscillation effect ye ultrasonic, kuitira kuti abrasive ikuyiwe uye ipukutwe pamusoro pe workpiece. Ultrasonic machining ine simba diki re macroscopic uye haizokonzere deformation ye workpiece, asi zvakaoma kugadzira nekuisa ma tooling. Ultrasonic processing inogona kusanganiswa ne chemical kana electrochemical methods. Zvichibva pakuora kwe solution uye electrolysis, ultrasonic vibration inoshandiswa kumutsa solution, kuitira kuti zvigadzirwa zvakanyungudutswa pamusoro pe workpiece zviparadzaniswe, uye corrosion kana electrolyte iri pedyo nepamusoro ive yakafanana; cavitation effect ye ultrasonic mumvura inogonawo kudzivirira corrosion process uye kuita kuti surface lightening ive nyore.
Kupukuta kwemvura
Kupukuta kwemvura kunoshandisa mvura inoyerera nekukurumidza uye zvinhu zvinokwesha zvinotakurwa nayo kuti zvisuke pamusoro pechinhu chebasa kuti zvizadzise chinangwa chekupukuta. Nzira dzinowanzo shandiswa ndeidzi: kugadzira jet inokwesha, kugadzira jet inokwesha, kukuya kwehydrodynamic nezvimwewo. Kukuya kwemvura kunofambiswa nekumanikidzwa kwe hydraulic kuti mvura inotakura zvinhu zvinokwesha zviyerere mberi nekudzoka pamusoro pechinhu chebasa nekumhanya kukuru. Chinhu ichi chinogadzirwa zvakanyanya nezvinhu zvakakosha (zvinhu zvakaita se polymer) zvine simba rekuyerera zvakanaka pasi pekumanikidzwa kwakaderera uye zvinosanganiswa nezvinhu zvinokwesha. Zvinhu zvinokwesha zvinogona kugadzirwa ne silicon carbide powder.
Kukuya nekupukuta zvine magineti
Kupukuta kwemagnetic abrasive kunoshandiswa kushandisa ma magnetic abrasives kugadzira mabhurashi anobaya pasi pesimba remagineti kuti agaye workpiece. Nzira iyi ine kushanda zvakanaka, mhando yakanaka, kudzora zviri nyore mamiriro ekugadzirisa uye mamiriro ekushanda akanaka. Uchishandisa ma abrasives akakodzera, kuomarara kwenzvimbo kunogona kusvika Ra0.1μm. 2 Kupukuta kwemuchina zvichibva panzira iyi Kupukuta kunotaurwa mukugadzirisa mapurasitiki epurasitiki kwakasiyana zvikuru nekupukuta kwepamusoro kunodiwa mune mamwe maindasitiri. Kutaura chokwadi, kupukuta kwemold kunofanira kunzi girazi processing. Haingori nezvinodiwa zvepamusoro zvekupukuta chete, asiwo ine zviyero zvepamusoro zvekuti pamusoro payo pave pakadzikama, panyoro uye pakururama kwejometri. Kupukuta kwepamusoro kunowanzoda chete nzvimbo yakajeka. Mwero wekugadzirisa pamusoro pegirazi wakakamurwa kuita mazinga mana: AO=Ra0.008μm, A1=Ra0.016μm, A3=Ra0.032μm, A4=Ra0.063μm. Zvakaoma kudzora kunyatsojeka kwejometri yezvikamu nekuda kwenzira dzakadai sekupukuta kwemagetsi uye kupukuta kwemvura. Zvisinei, mhando yepamusoro yekukwesha kwemakemikari, kukwesha kwe ultrasonic, kukwesha kwe magnetic abrasive nedzimwe nzira hadzina kukwana zvinodiwa, saka kugadzirisa magirazi emhando dzema molds kuchiri kunyanya kukwesha kwemuchina.
