Precision inoshandiswa kuratidza kunaka kwechigadzirwa chebasa. Iri inguva yakakosha yekuongorora iyo geometric paramita yepasi machining uye yakakosha chiratidzo chekuyera mashandiro eCNC machining nzvimbo. Kazhinji kutaura, kunyatsoita machining kunoyerwa negiredhi rekushivirira. Iyo yakaderera giredhi, iyo yakakwirira yekururama. Kutendeuka, kugaya, kuronga, kukuya, kuchera, uye kufinha ndiwo akajairika machining mafomu eCNC machining nzvimbo. Saka ndeapi machining echokwadi anofanira kuita aya machining maitiro?
1.Kushandura kururama
Kutendeuka kunoreva nzira yekucheka iyo iyo workpiece inotenderera uye chishandiso chekushandura chinofamba mumutsara wakatwasuka kana curve mundege, iyo inoshandiswa kugadzirisa mukati nekunze cylindrical nzvimbo, magumo zviso, conical nzvimbo, kugadzira nzvimbo uye tambo dze. workpiece.
The pamusoro roughness kutendeuka iri 1.6-0.8μm.
Kutenderedza kwakakasharara kunoda kushandiswa kwekudzika kukuru kwekucheka uye chiyero chakakura chekudya kuti uvandudze kushandura zvakanaka pasina kudzikisa kumhanya kwekucheka, uye kushata kwepamusoro kunodiwa 20-10um.
Xinfa CNC zvishandiso zvine hunhu hwemhando yakanaka uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:CNC Zvishandiso Vagadziri - China CNC Zvishandiso Factory & Suppliers (xinfatools.com)
Semi-kupedza uye kupedzisa kutendeuka edza kushandisa kukurumidza uye diki diki rekudya uye kudzika kwekucheka, uye kushata kwepamusoro i10-0.16um.
Iyo yakakwenenzverwa dhaimondi inotenderedza chishandiso pane yakakwirira-chaiyo lathe inogona kushandura isiri-ferrous simbi workpieces nekumhanya kukuru, nekukasharara kwe 0.04-0.01um. Kutendeuka kwerudzi urwu kunonzi zvakare "mirror turning".
2. Kugaya kwakanyatso kugaya kunoreva kushandiswa kwezvishandiso zvinotenderedza akawanda-blade kucheka zvidimbu zvebasa, iyo inonyatso shanda nzira yekugadzirisa.
Inokodzera kugadzirisa ndege, grooves, uye akasiyana splines, magiya, tambo mold uye mamwe akakosha nzvimbo.
Kuoma kwepamusoro pekugaya kunowanzo 6.3-1.6μm. Kukasharara kwepamusoro kwegayo kuri 5-20μm.
Kuoma kwepamusoro kwehafu-yekupedzisira milling ndeye 2.5-10μm. The pamusoro roughness of fine milling is 0.63-5μm.
3. Kuronga kwakarurama
Kuronga inzira yekucheka inoshandisa planer kugadzira yakatwasuka mutsara mutsara inodzokorodza mafambiro pane workpiece, inonyanya kushandiswa kugadzira chimiro chezvikamu. Iyo yepamusoro roughness ye planing ndeye Ra6.3-1.6μm.
Kushata kwepamusoro kwe rough planing ndeye 25-12.5μm. Iko kushata kwepamusoro kwehafu-yekupedzisira planing ndeye 6.2-3.2μm. Iko kushata kwepamusoro kwekuronga kwakanaka ndeye 3.2-1.6μm.
4. Kukuya kururamisa Kukuya kunoreva nzira yekugadzira yekushandisa mabrasives uye maturusi ekukuya kuti abvise zvinhu zvakawandisa pane workpiece. Ndeyekugadzirisa zvakanaka uye inoshandiswa zvakanyanya muindasitiri yekugadzira michina.
Kukuya kunowanzo shandiswa semi-kupedza uye kupedzisa, uye kushata kwepamusoro kunowanzo 1.25-0.16μm.
Kukasharara kwepamusoro kwekuita kugaya ndiko 0.16-0.04μm.
Kukasharara kwepamusoro-soro kukuya kwe 0.04-0.01μm. Hushasha hwepamusoro hwegirazi kugaya hunogona kusvika pasi pe0.01μm.
5. Kufinha
Iyo nzira yekucheka iyo inoshandisa chishandiso kuwedzera dhayamita yemukati yegomba kana imwe denderedzwa contour. Chishandiso chayo chinowanzosiyana kubva pahafu-roughing kusvika pakupedza. Chishandiso chinoshandiswa chinowanzo chema-chete chinobhowa (chinonzi boring bar).
Iko kufinha kwechokwadi kwezvinhu zvesimbi zvinogona kusvika 2.5-0.16μm.
Iko kugadzirisa kurongeka kweiyo chaiyo kufinha inogona kusvika 0.63-0.08μm.
