Kana vanhu vazhinji vakanzwa 'chaiyo yepurasitiki machining', vanofungidzira muchina weCNC uchirira kure, pamwe imba yakachena, uye zvikamu zvinotaridzika zvakanaka. Ndiwo mufananidzo wekushambadzira. Chokwadi, icho chaunodzidza mushure mekurasa mazana mashoma emadhora 'yakakosha PEEK kana kuona yakasimba-kushivirira UHMWPE chikamu warp vhiki mushure mekusununguka, ndeyekuti kunyatsojeka uku kune zvakawanda nezvezvinhu zvepfungwa sezvazviri nezvemashini calibration. Inhaurirano pakati pekuomarara kwesimbi-yekucheka dzidziso uye inoshanduka, kazhinji inoshatirwa, hunhu hwemapolima. Zvitoro zvakawanda zvinopenya nesimbi zvinogumburwa pano, zvinobata mapurasitiki searuminiyamu yakapfava, uye ndipo panotangira matambudziko — uye kudzidza chaiko.
Chinyorwa ndicho Chekutanga Kusiyanisa, Kwete Kugara Kuripo
Iwe haugone kungoisa generic epurasitiki chirongwa. Mhuri yega yega yepolymer inoita semhando dzakasiyana. Machining delrin (POM) chiroto-yakagadzikana, inofanotaurwa, machipisi zvakanaka. Unowana pfungwa yenhema yekuchengeteka. Wobva wachinja naironi kana PTFE, uye kamwe-kamwe uri kurwisa kunyura kwehunyoro uye kuwedzera kwekupisa kwepakati-cheka. Chikamu chawakayera zvakakwana pabhenji remuchina chabuda kunze kweawa gare gare. Ndakadzidza izvi nenzira yakaoma pakutanga nekumhanya kwePOM bushings yaifanira kusangana nemapini asina tsvina. Takaroverera kushivirira, asi mutengi akafona zvakare: mabhunu airira. Sei? Isu taivagadzira zvakachena zvakanyanya, kumeso kwacho kwainyanya kutsvedzerera kutsvedza kwaidiwa. Dzimwe nguva, kumapurasitiki, kupedzisa kwepamusoro kwepamusoro haisi iyo yakatsetseka pane chati.
Apa ndipo panobva pava neukoshi hwekugadzirisa zvinhu. Tora kambani yakafanana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Neanopfuura makore makumi matatu ekukandira nekugadzira simbi - kunyanya zvinhu zvinonyengerera senge nickel-based alloys - vanosvika kune zvinhu neruremekedzo rwakadzika-dzika kune zvekuzvarwa zvivakwa. Mafungiro iwayo anoturikira. Kana vachibata kunyatsogadzira epurasitiki machining, haisi yedivi; Kushandiswa kwesainzi iyoyo yakaomarara. Kuziva maitiro ekugadzirisa kupisa kwekuisa uye kushushikana mune superalloy kunopa iwe intuitive mupendero wekutonga zvakafanana mupurasitiki-inoshanda sePEEK, uko kusara kunetseka muvengi wekugadzikana kwedimensional.
Iyo yekutonhodza nzira ndeye classic gomba. Mafashama anotonhodza? Kazhinji pfungwa inotyisa kune akawanda hygroscopic mapurasitiki. Inogona kupinda mukati uye kukonzera kuzvimba gare gare. Mhepo yakamanikidzwa iri nani, asi iwe unofanirwa kubata static uye chip evacuation. Kune mamwe majiometri, takawana mibairo yakanaka kubva kune yakapusa, yakanangwa mhute inotonhorera ine dielectric fluid chaiyo, chimwe chinhu chatakagadzirisa mushure mekutaura nemugadziri wekuumba. Aya madiki magadzirirwo ekugadzirisa, asina kumbotaurwa mubhuku remuchina, anotsanangura chokwadi chaicho.
Tooling uye Kugadzirisa: Iyo Yakavanzika Art yeKubata Kumashure
Munhu wese anotarisa pamusoro pechishandiso chejeometry-rake angles, helix yemapurasitiki, nezvimwewo. Izvo zvakakosha, chokwadi. Asi kugadzirisa ndiko kunogara mabasa kana kufa. Kusungirira zvakanyanya paPC yakatetepa-yakakomberedzwa kana acrylic chubhu? Iwe uchaona zvakadhindwa, kana zvakanyanya, gadzira nzvimbo yekushushikana inotsemuka gare gare. Vacuum chucks yakanaka, asi kune prototype kana yakaderera-vhoriyamu inomhanya, iwe unowana kugadzira. Isu takashandisa tsika dzakapfava-shaya dzakagadzirwa kubva kune yakaderera-durometer urethane, kana kunyangwe zvine hungwaru kushandiswa kwekaviri-mativi tepi yezvikamu zvidiki, zvisina-ferrous. Chinangwa ndechekuibata zvakakwana kuti irambe masimba ekucheka, asi kwete kuikanganisa. Manzwiro aunoita.
Kupfeka kwemidziyo kunoitika zvakasiyana, zvakare. Musimbi, unoona nyika inopfeka yeflank. Mumapurasitiki akazadzwa-abrasive senaironi yakazadzwa negirazi, mupendero wekucheka unogona kuwana yakakwenenzverwa, inenge yakagomara kutaridzika kwenguva refu isati yadonha, uye kupera kwako kwepamusoro kunodzikisira chinyararire. Iwe unofanirwa kutevedzera izvi nechikamu chemhando, kwete chete neawa mita. Isu takaisa danda rakareruka kune zvimwe zvinhu: Chikamu 50 pamusoro Ra cheki. Yakabata inodarika chishandiso chimwe chinodzikisira isati yaparadza batch.
Apo Precision Inosangana Nenyika Chaiyo
Mhosva inomira neni yaive mutengi aida diki, yakaoma manifold kubva muPVDF yemuchina wekuongorora makemikari. Iwo anodhinda anodaidzira ± 0.025mm pane akati wandei anobatanidza mabhora. Isu takaigadzira, tikaiyera paCMM, uye yaive yakakwana. Takaitumira. Zvakakona mugungano ravo. Sei? Vaishandisa simbi isina simbi ine shinda, uye kuita kwekuitsikirira mukati kwakaunza kupisa kwakakwana kwenzvimbo uye kushushikana kukanganisa bhora riri padyo nemakroni mashoma-zvakakwana kuputsa kushivirira. Kugadzira kwedu chaiko kwaive kusina kukanganisa, asi isu hatina kuverengera danho rinotevera muhupenyu hwechikamu.
Kukundikana ikoko kwakamanikidza kuchinja kwemaitiro. Kune zvikamu zvinotevera, isu takawedzera nhanho-yekuzorodza annealing nhanho post-machining, uyezve yekupedzisira mwenje yekupedzisa pass. Yakawedzera mutengo uye nguva, asi yakaendesa chikamu chakaramba chakatsiga mumunda. Ndiyo yakavanzika layer ye kunyatsogadzira epurasitiki machining: haisi iyo mamiriro echikamu painobuda muchitoro, asi mamiriro ayo kana yaiswa kushanda. Aya maonero akazara chimwe chinhu chaunowanzo kuona muzvitoro chine nhaka muzvikamu zvakakosha. QSY, semuenzaniso, nenhoroondo yayo mukudyara kwekudyara uye machining ekuda ma alloys, akarongeka anoshandiswa kufunga nezve post-processing, kupisa kurapwa, uye kwekupedzisira kuita, kwete kungoita machining danho rekuzviparadzanisa nevamwe.
Iyo Bridge kubva kuMetal kuenda kuPlastiki
Pane fungidziro isiriyo yekuti machina epurasitiki idanho rekudzika kubva kusimbi. Hazvisizvo. Iyo inoenderana track ine yayo yega PhD-level matambudziko. Muchokwadi, hunyanzvi mune yakaoma-ku-muchina simbi inogona kuve mukana wakakura. Chirango chekudzora kuzunguzika, kupisa, uye kutsauswa kwezvishandiso paunenge uchigaya Inconel inozivisa zvakananga masvikire aunoita girazi rakazadzwa composite. Mafungiro einjiniya maitiro pamusoro pemachining ari nyore akakosha.
Ini ndinotarisa kugona kwekambani yakafanana QSY. Shell mold cast, kuisa mari, CNC machining ecobalt uye nickel alloys - aya maitiro anoda kunyanyisa kutonga. Kushandisa iyo imwechete yekudzora sisitimu, iwowo kuongorora kumwechete kune zvitupa zvenyama uye magadzirirwo paramita, kumapurasitiki ndizvo zvinoisimudza kubva nyore kuita chikamu kusvika kune yakavimbika. kunyatsogadzira epurasitiki machining. Zvinoreva kunzwisisa kuti chimiro chestock (tsvimbo, ndiro, yakaumbwa isina chinhu) ine nhoroondo yayo yekushushikana, kuti tembiricha yechitoro inobata, uye kuti kurongedza kwekutumira kunogona kukanganisa hunyoro.
Pakupedzisira, Zviri Nezve Kutarisira
Saka, chii chinotorwa mushure memakore eizvi? Precision haingori nhamba pane zvakadhindwa. Ihurongwa. Inotanga nekunyatsoteerera kune zvinyorwa-kuziva kuti nylon inotora mvura, iyo acetal ine nzvimbo yakaderera yakanyunguduka, iyo PTFE ichakwira pasi pemutoro. Inoenderera mberi nekugadzira maitiro anoremekedza aya ma quirks, ane maturusi enzira anodzikisira kupisa, zvigadziriso zvisingakanganise, uye zviyero zvinotorwa munzvimbo yakagadzikana mushure mekunge chikamu chagadzikana.
Inopera, zvakanyanya kukosha, nekufungidzira zvichaitika kune chikamu mushure mekunge chasiya bhenji rako. Ichaunganidzwa here? Ichaona kutenderera kwetembiricha? Pane chikamu chesimbi chichaiswa mairi here? Icho chekupedzisira chidiki chekuona zviri mberi ndicho chinopatsanura nyanzvi yemuchina kubva kune yechokwadi yekugadzira mudiwa. Ndiwo mutsauko uripo pakati pekugadzira chikamu chakanyatso muvacuum uye kuendesa chikamu chinoita kuti mutsara wemutengi usamire, kana chigadzirwa chavo hachikundike. Ndicho chinangwa chaicho, uye kutaura chokwadi, chinhu chega chakakosha. Michina ingori midziyo yekusvika ikoko; ruzivo ndirwo runoita kuti zvive nemazvo.
