Zvimiro zveMilling Cutters
Paunenge uchibata nezvinhu zvakaoma-ku-muchina zvakadai seHastelloy, waspaloy, Inconel naKovar, ruzivo rwekugadzira uye ruzivo rwakakosha zvikuru. Parizvino, kune akawanda uye akawanda maapplication e nickel-based alloys, anonyanya kushandiswa kugadzira zvimwe zvakakosha zvikamu muaerospace, zvekurapa uye zvemakemikari maindasitiri. Zvinhu izvi zvine simba rakawanda, corrosion resistance, uye zvinokwanisa kumira zvakanyanya tembiricha. Zvimwe zvinhu zvakakosha zvinowedzerwa kune zviri pamusoro apa kuti uwane kuita kwepamusoro. Nekune rumwe rutivi, zvakadaro, zvinhu izvi zvakare zvinonyanya kunetsa kukuya.
Isu tinoziva kuti nickel nechromium ndiwo maviri makuru ekuwedzera mune nickel-based alloys. Kuwedzera nickel kunogona kuwedzera kuoma kwezvinhu, kuwedzera chromium kunogona kuvandudza kuoma kwezvinhu, uye kuenzana kwezvimwe zvikamu zvinogona kushandiswa kufanotaura kupera kwechishandiso. Zvimwe zvinhu zvinowedzerwa kune zvinyorwa zvinogona kusanganisira: silicon, manganese, molybdenum, tantalum, tungsten, nezvimwewo. Zvinokosha kucherechedza kuti tantalum uye tungsten ndizvowo zvinhu zvikuru zvinoshandiswa kugadzira simende carbide, iyo inogona kubudirira kuvandudza kushanda kwecemented carbide , asi kuwedzerwa kwezvinhu izvi kune workpiece zvinhu zvinoita kuti zviome kugayo, zvinenge sekucheka imwe carbide tool neimwe.
Sei vanocheka zvigayo vachicheka zvimwe zvinhu nekukurumidza kana vachikuya nickel-based alloys? Zvakakosha kunzwisisa izvi. Machining nickel-based alloys, mutengo wezvishandiso wakakwira, uye mutengo wakapetwa kashanu kusvika kagumi pane wekugaya general simbi.
Hazvina maturo kutaura, kupisa ndicho chinhu chinonyanya kukosha chinokanganisa hupenyu hwezvishandiso kana kugaya nickel-based alloys, nekuti kunyange yakanakisa carbide maturusi anogona kuparadzwa nekupisa kwekucheka kwakanyanya. Chizvarwa chekupisa kwakanyanya kwekucheka harisi dambudziko rekugaya nickel alloys. Saka pakukuya aya alloys, kupisa kunoda kudzorwa. Mukuwedzera, zvakakosha zvikuru kuziva kukosha kwekupisa kunogadzirwa paunenge uchigadzira nemhando dzakasiyana-siyana dzezvishandiso (high-speed steel tools, carbide tools kana ceramic tools).
Mazhinji kukuvadzwa kwezvishandiso ane chekuitawo nezvimwe zvinhu, uye zvigadziriso zvisingaite uye zvibatiso zvematurusi zvinogona kupfupisa hupenyu hwematurusi. Kana iyo kuomarara kweiyo clamped workpiece isina kukwana uye kufamba kunoitika panguva yekucheka, kunogona kukonzera kuputsika kweiyo simende carbide matrix. Dzimwe nguva kutsemuka kudiki kunokura padivi pekucheka, uye dzimwe nguva chimedu chinopwanya kubva pakaiswa carbide, zvichiita kuti zvisaite kuramba uchicheka. Ehe, ichi chipping chinogona zvakare kukonzerwa nekuomesesa carbide kana yakawandisa kucheka mutoro. Panguva ino, maturusi esimbi akakwira-kumhanya anofanirwa kutariswa kuti agadziriswe kuderedza kuitika kwechipping. Ehe, maturusi esimbi anomhanya-mhanya haagone kumira kupisa kwakanyanya senge simende carbide. Chaizvo zvinhu zvekushandisa zvinofanirwa kutariswa pane imwe nyaya-ne-nyaya.
