Precision inoshandiswa kuratidza kunaka kwechigadzirwa chebasa. Iri izwi rakakosha rekuongorora ma geometric parameters enzvimbo yakagadzirwa nemichina. Iyo zvakare yakakosha chiratidzo chekuyera mashandiro eCNC machining nzvimbo. Kazhinji kutaura, kurongeka kwekugadzira kunoyerwa nemazinga ekushivirira. Iyo yakaderera mwero, iyo yakakwirira yekururama. Kutendeuka, kugaya, kuronga, kukuya, kuchera, uye kufinha ndiwo maitiro akajairika ekugadzirisa CNC machining nzvimbo. Saka ndedzipi kugadzirisa kurongeka kunofanirwa kuita maitiro aya ekugadzirisa?
1.Kushandura kururama
Kutendeuka kunoreva nzira yekucheka iyo iyo workpiece inotenderera uye chishandiso chekushandura chinofamba zvine mutsetse kana chakakombama mundege kuti igadzirise mukati nekunze cylindrical nzvimbo, magumo zviso, conical nzvimbo, kuumba nzvimbo uye shinda dzechishandiso.
The pamusoro roughness kutendeuka iri 1.6-0.8μm.
Kushandura kwakakasharara kunoda kushandiswa kwekudzika kukuru kwekucheka uye chiyero chikuru chekudya kuti uvandudze kutendeuka kushanda pasina kudzikisa kukurumidza kwekucheka. Iko kushata kwepamusoro kunodiwa kuve 20-10um.
Kune semi-kupedzisa uye kupedzisa kutendeuka, edza kushandisa kumhanya kwakakwira uye kudiki chikafu nekudzika kudzika, uye kushata kwepamusoro i10-0.16um.
Maturusi ekutenderedza madhaimani pasi anoshandiswa pamhando yepamusoro-chaizvo kupedzisa kutenderedza simbi isina-ferrous workpieces nekumhanya kukuru nekukasharara kwe 0.04-0.01um. Kutendeuka kwerudzi urwu kunonzi zvakare "mirror turning".
Xinfa CNC zvishandiso zvine hunhu hwemhando yakanaka uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:

2. Kugaya chokwadi
Kugaya kunoreva kushandiswa kwematurusi anotenderedza akawanda-akacheka kucheka zvidimbu zvebasa, uye inzira inoshanda kwazvo yekugadzirisa. Inokodzera kugadzira ndege, magrooves, uye yakakosha nzvimbo senge splines, magiya, uye akarukwa mold.
Iyo yakawanda pamusoro pehukukutu hwekugaya kugadzirisa iko kurongeka ndeye 6.3-1.6μm.
The pamusoro roughness panguva rough milling iri 5-20μm.
The pamusoro roughness panguva semi-kupedza milling iri 2.5-10μm.
Kushata kwepamusoro panguva yekugaya kwakanaka ndeye 0.63-5μm.
3.Kuronga kunyatsoita
Kuronga inzira yekucheka yekugadzira iyo inoshandisa planer kuita yakachinjika uye mutsara inodzokorodza mafambiro pane workpiece. Inonyanya kushandiswa pakugadzirisa 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.Kugaya kururama
Kukuya zvinoreva nzira yekugadzira iyo inoshandisa mabrasives uye abrasive maturusi ekubvisa yakawandisa zvinhu kubva paworkpiece. Iyo inzira yekupedzisa uye inoshandiswa zvakanyanya muindasitiri yekugadzira michina.
Kukuya kunowanzo shandiswa semi-kupedza uye kupedzisa, uye kushata kwepamusoro kunowanzo 1.25-0.16μm. Iyo chaiyo yekukuya roughness ndeye 0.16-0.04μm.
Kukasharara kwepamusoro-soro kukuya kwe 0.04-0.01μm.
Iko kushata kwepamusoro kwegirazi kugaya kunogona kusvika pazasi 0.01μm.
5. Zvinofinha uye zvinofinha
Iyo yemukati dhayamita yekucheka maitiro inoshandisa chishandiso kukudza gomba 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.
