Mukuita kwekugadzira titanium alloy mold, iyo yakatsetseka kugadzirisa uye girazi kugadzirisa mushure mekugadzirwa kwechimiro kunonzi chikamu chepamusoro kugaya uye kukwenenzverwa, ayo ari maitiro akakosha ekuvandudza kunaka kwe mold. Kuziva nzira inonzwisisika yekupukuta inogona kuvandudza mhando uye hupenyu hwesevhisi yetitanium alloy molds, uye wobva wavandudza mhando yechigadzirwa. Nhasi, nyanzvi kubva kuRSM Tekinoroji Dhipatimendi ichagovera ruzivo rwakakodzera nezve titanium alloy kunangwa kupukuta.
Yakajairika polishing nzira uye nheyo dzekushanda
1. Titanium alloy chinangwa chemagetsi kupenya
Mechanical polishing inzira yekupukuta inobvisa iyo convex chikamu chenzvimbo yebasa kuti iwane nzvimbo yakatsetseka nekucheka kana kutsvedza pasi pevhu. Kazhinji, matombo emafuta, mavhiri emvere dzemakwai, sandpaper, nezvimwe zvinoshandiswa. Manual operation ndiyo nzira huru. Ultra precision polishing inogona kushandiswa kune avo vane yepamusoro yepamusoro zvinodiwa. Ultra precision lapping uye polishing inoshandisa special abrasives. Mumvura yekuputira uye yekupukuta ine mabrasives, inotsikirirwa pakatarisana neyakagadzirwa pamusoro peiyo workpiece yekumhanya-mhanya kutenderera. Neiyi tekinoroji, ra0.008 inogona kuwanikwa μ M UM, inova yakanakisa kushata kwepamusoro pakati penzira dzakasiyana dzekupukuta. Iyi nzira inowanzoshandiswa mu optical lens molds. Mechanical polishing ndiyo nzira huru yekugadzira mold.
2. Titanium alloy chinangwa chemakemikari polishing
Kemikari polishing ndeyekuita kuti iyo micro convex chikamu chepamusoro chinyunguduke zviri nani pane iyo concave chikamu chepamusoro muchemikari yepakati, kuitira kuti iwane nzvimbo yakatsetseka. Iyi nzira inogona kupuruzira yakaoma maumbirwo emabasa, uye inogona kupuruzira akawanda maworkpiece panguva imwe chete nepamusoro-soro. Iko kushata kwepamusoro kunowanikwa nemakemikari polishing kazhinji RA10 μ m.
3.Titanium alloy target electrolytic polishing
Nheyo yekutanga yekukwenenzverwa kwemagetsi yakafanana neyekupenya kwemakemikari, ndiko kuti, nekusarudza kunyungudutsa tunhu tudiki twunobuda pamusoro pechinhu chacho, nzvimbo yacho inotsvedzerera. Kuenzaniswa nemakemikari polishing, inogona kubvisa pesvedzero ye cathode reaction uye ine mhedzisiro iri nani.
4. Titanium alloy target ultrasonic polishing
Ultrasonic polishing inzira yekupukuta brittle uye yakaoma zvinhu kuburikidza neabrasive suspension ne ultrasonic vibration yechikamu chezvishandiso. Iyo workpiece inoiswa mu abrasive suspension uye yakaiswa mumunda we ultrasonic pamwe chete. Iyo abrasive ivhu uye yakakwenenzverwa pane workpiece pamusoro neiyo oscillation ye ultrasonic wave. Iyo macro force ye ultrasonic machining idiki, iyo isingazokonzerese workpiece deformation, asi yakaoma kugadzira uye kuisa tooling.
5. Titanium alloy target fluid polishing
Fluid polishing inotsamira pamvura inoyerera uye mabrasive particles ayo anotakura kugeza pamusoro pechishandiso kuti chizadzise chinangwa chekupukuta. Hydrodynamic kugaya inofambiswa ne hydraulic pressure. Iyo yepakati inonyanya kugadzirwa neakakosha makomisheni (polymer senge zvinhu) ine yakanaka kuyerera pasi pekumanikidzwa kwakaderera uye yakasanganiswa nemaabrasives. Iwo mabrasives anogona kunge ari silicon carbide poda.
