Kuenzanisa kweHigh-Speed Steel uye Cemented Carbide Materials
High-speed simbi (HSS) uye simende carbide zvinhu zviviri zvinowanzo shandiswa mumaindasitiri akasiyana, kunyanya mukucheka maturusi uye machining application. Zvishandiso zvese zviri zviviri zvinoratidzira zvakasarudzika zvivakwa zvinoita kuti zvikodzere kune chaiwo zvinangwa. Muchikamu chino, tichafananidza nekusiyanisa maitiro e-high-speed iron uye simende carbide, tichitarisa pakuumbwa kwavo, kuoma, kuoma, kusapfeka, uye kushanda kwese.
Kuumbwa:
High-Speed Simbi: High-speed simbi ialloy inoumbwa zvakanyanya nesimbi, kabhoni, cobalt, tungsten, molybdenum, uye vanadium. Aya maalloying zvinhu anowedzera kuomarara kwechinhu, kupfeka kuramba, uye kusimba kwepamusoro-tembiricha.
Cemented Carbide: Cemented carbide, inozivikanwawo se tungsten carbide, ine hard carbide phase (kazhinji tungsten carbide) yakamisikidzwa mubinder simbi senge cobalt kana nickel. Uku kusanganiswa kunopa izvo zvinhu nekuomarara kwakasiyana uye kupfeka kuramba.
Kuoma:
High-Speed Simbi: HSS kazhinji ine kuoma kubva pa55 kusvika 70 HRC (Rockwell C scale). Iyi nhanho yekuomarara inobvumira maturusi eHSS kuti anyatso kucheka mukati memhando dzakasiyana dzezvinhu, zvinosanganisira simbi, simbi isina tsvina, uye simbi yakakandwa.
Cemented Carbide: Cemented carbide inozivikanwa nekuoma kwayo kwakanyanya, kazhinji inosvika 80 kusvika 95 HRA (Rockwell A scale). Kuomarara kwepamusoro kunoita simende maturusi ecarbide akanakira kugadzira zvinhu zvakaomarara senge titanium alloys, simbi dzakaomeswa, uye macomposites.
Kuoma:
High-Speed Simbi: HSS inoratidza kusimba kwakanaka uye inokwanisa kumirisana nehupamhi hwepamusoro uye mitoro yekuvhunduka, ichiita kuti ive yakakodzera kune yakakanganiswa kucheka uye inorema machining mashandiro. Kuomarara kwayo kunobatsirawo kugadzikwa zvakare nekugadzirisa zvakare maturusi.
Cemented Carbide: Nepo simende carbide yakaoma zvakanyanya, haina brittle kana ichienzaniswa neHSS. Inogona kuputika kana kutsemuka pasi pesimba rinorema kana mitoro yekuvhunduka. Nekudaro, magiredhi emazuva ano ecarbide anosanganisira kuomarara kwakavandudzwa uye anogona kumira pakati nepakati kusvika kuchiedza.
Wear Resistance:
Yakakwira-Speed Simbi: HSS ine yakanaka kupfeka kuramba, kunyanya kana ichishandiswa pakaderera kucheka kumhanya. Nekudaro, pakumhanya kukuru kwekucheka kana kana uchigadzira zvinhu zvine abrasiveness yakanyanya, kushomeka kweHSS kunogona kunge kusina kukwana.
Cemented Carbide: Cemented carbide ine mukurumbira nekusarudzika kupfeka kuramba kunyangwe mumamiriro ezvinhu akaoma machining. Iyo yakaoma carbide chikamu inopa kukwirira kupikisa kune abrasive kupfeka, ichibvumira maturusi ecarbide kuchengetedza iwo ekucheka mupendero kwenguva yakareba.
Kuita:
High-Speed Simbi: Zvishandiso zveHSS zvinokunda mumhando dzakasiyana dzekucheka zvikumbiro nekuda kwekusiyana-siyana, kuoma, uye kureruka kwekurodza. Iwo akakodzera kune zvakajairwa-chinangwa machining mashandiro uye ane mutengo-unoshanda kana uchienzaniswa necemented carbide.
Cemented Carbide: Cemented carbide maturusi anoshandiswa zvakanyanya kune yakakwira chaiyo uye yakakwirira-inoshanda machining. Ivo vanoita zvakanyanya mushe mukuda maapplication ane yakanyanya kuchekwa kumhanya, yakawedzerwa hupenyu hwematurusi, uye kuwedzera kubereka. Nekudaro, iwo anowanzo kudhura kupfuura maturusi eHSS.
Mhedziso:
Simbi yepamusoro-soro uye cemented carbide zvose zvinhu zvinokosha mumhizha yekucheka maturusi, imwe neimwe iine simba rayo uye zvisingakwanisi. Simbi yepamusoro-soro inopa kusimba kwakanaka, kuita zvakasiyana-siyana, uye kudhura-kushanda, zvichiita kuti ive yakakodzera kune zvakasiyana-siyana zvekushandisa machining. Kune rumwe rutivi, carbide yakasimbiswa inokunda mukuoma, kusapfeka, uye kugadzikana kwepamusoro-soro, zvichiita kuti ive sarudzo inosarudzwa yekugadzira simbi dzakaomeswa nezvimwe zvinhu zvakaoma.
Kunzwisisa izvo zvinodikanwa zvekugadzira machining uye iyo workpiece zvinhu zvakakosha pakusarudza iyo yakakodzera zvinhu. Zvinhu zvakadai sekumhanya kwekucheka, kuoma kwezvinhu, uye hupenyu hwematurusi hunodiwa zvinofanirwa kunyatsotariswa. Pakupedzisira, sarudzo pakati pesimbi yepamusoro-soro uye simende carbide ichaenderana nekushandiswa kwakananga uye migumisiro inodiwa.
