Yakakwirira Precision Plastic CNC Machining Zvikamu
Ndeapi akajeka eakasiyana CNC zvinhu?
CNC machining inogona kugadzira zvikamu kubva kune chero simbi kana plastiki.Zvinhu zvekufarira zvezvinhu izvi ndezvi:
1. mechanical simba: inoratidzwa ne tensile goho simba;
2. machinability: kusununguka kwekugadzira kunokonzera mutengo weCNC;
3. mutengo wezvinhu;
4. kuoma: kunyanya kune simbi;
5. kupikisa kwekushisa: kunyanya kune mapurasitiki.
CNC Metals
Zvishandiso zvinoda kusimba kwepamusoro, kuoma, uye kupisa kwekupisa zvinoshandisa simbi kana, asi, masimbi alloys.
1.Aluminium: yakashandiswa kugadzira zvikamu zvesimbi zvetsika uye prototypes.
2.Simbi isina ngurainogona kugadzirwa zviri nyore, kugadzirwa nemichina, uye kukwenenzverwa.
3.Simbi yakapfava, kana pasi-kabhoni simbi: inoshandiswa kumakina zvikamu, jigs, uye zvigadziriso.
4.Alloy simbiine mamwe maalloying maelement kuwedzera kune kabhoni yekuvandudza kuoma, kuoma, kuneta, uye kupfeka kuramba.
5.Tool simbiinobatsira pakugadzira maturusi akadai sefa, zvitambi, uye mold.
6.Brassyakanakira zvikumbiro zvinoda kukweshana kwakaderera uye dhizaini kugadzira zvikamu zvinotaridzika segoridhe nekuda kwekunakisa.
CNC Plastiki
Mapurasitiki zvinhu zvakareruka zvine akasiyana emuviri zvimiro, anowanzo shandiswa kune yavo makemikari kuramba uye magetsi ekudzivirira maitiro.
1.ABS: inowanzo shandiswa kugadzira prototypes isati yagadzirwa yakawanda nekuumba jekiseni.
2.Nylon, kana polyamide (PA): inonyanya kushandiswa kwehunyanzvi hwekushandisa nekuda kweiyo yakanakisa mechaniki zvivakwa, kusimba kwesimba, uye yakakwirira kuramba makemikari uye abrasion.
3.Polycarbonateinowanzo jeka pachena, zvichiita kuti ive yakakodzera kune akawanda maapplication, akadai semidziyo yemvura kana kupenya kwemotokari.
POM (Delrin) ndicho chinhu chesarudzo cheCNC machining kana zvikamu zvinoda:
1. kunyatsojeka
2. kuoma kwepamusoro
3. low friction
4. yakanakisa dimensional kugadzikana pakudziya kwakanyanya
5. kunyura kwemvura kwakadzikira.
PTFE (Teflon) Inopesana nekushanda kwekushisa kwepamusoro pe200 ° C uye naizvozvo, iine insulator yemagetsi yakatanhamara.
High-density polyethylene (HDPE) yakakodzera kushandiswa kwekunze uye pombi.
PEEK: inonyanya kushandiswa kutsiva simbi zvikamu nekuda kweiyo yakakwirira simba-kusvika-huremu reshiyo.Magiredhi ekurapa anowanikwawo, zvichiita kuti PEEK ikwane kune biomedical application.
CNC Composite Zvishandiso
Macomposites, mumashoko akareruka, zvinhu zvakawanda zvine hunhu hwakasiyana hwemuviri nemakemikari zvinosanganiswa kugadzira chakasimba, chakareruka, kana dzimwe nguva chinochinjika chigadzirwa.
Imwe yeanonyanya kuzivikanwa macomposites pamusika ndeyeplastiki yakasimbiswa.Nhasi, plastiki inoshandiswa mune yakachena fomu mune zvakawanda zvigadzirwa, senge mumatoyi nemabhodhoro emvura.Zvisinei, inogona kusimbiswa nefibers kubva kune zvimwe zvinhu.Iyi tekinoroji inoita kuti mamwe akasimba, akareruka, uye anosiyana-siyana macomposites awanikwe.
Kushandiswa kwakajairwa kwecomposites kusimbisa chinhu chakachena nefiber kubva kune imwe yakachena kana inoumbwa.Mugadziri anowanzo wedzeracarbon kana graphite fiberskune imwe composite.Carbon fibers inofambisa, ine musanganiswa unoshamisa weyakakwira modulus uye kusimba kwesimba, ine yakaderera kwazvo (pashoma isina kunaka) CTE (coefficient yekuwedzera kwekupisa), uye inopa kuramba kwakanaka kune yakanyanya tembiricha.Aya maitiro anoita kabhoni faibha yakanakisa kumabhizinesi akasiyana siyana, uye inosanganisa nyore nezvinhu zvakawanda.
Mukuwedzera kune kabhoni,fiberglasschinhu chakajairika chakajairika fiber reinforcement material.Fiberglass haina kusimba kana kuomarara kunge kabhoni faibha, asi ine hunhu chaihwo hunoita kuti idiwe mumashandisirwo mazhinji.Girazi faibha harina conductive (kureva, insulator) uye kazhinji haionekwe kune mazhinji marudzi ekutapurirana.Izvi zvinoita kuti ive sarudzo yakanaka yemagetsi kana kutepfenyura maapplication.
Resinschikamu chakakosha chemakompositi.Ndiwo matrices anobata zvinhu zvakaparadzana pamwechete pasina iwo akanyatso kusanganiswa kuita chinhu chimwe chakachena.
