Machining precision inonyanya kushandiswa kuratidza kunaka kwezvigadzirwa, sengecnc kushandura zvikamuuyecnc milling zvikamu, uye ishoko rinoshandiswa kuongorora geometric parameters yezvivakwa zvemuchina. Machining kururama kunoyerwa neshiviriro giredhi. Iyo idiki kukosha kwegiredhi, iyo yakakwirira yekururama.
Kune makumi maviri emakirasi ekushivirira kubva kuIT01, IT0, IT1, IT2, IT3 kusvika IT18, iyo IT01 inomiririra iyo yepamusoro yekugadzirisa kurongeka kwechikamu, IT18 inomiririra yakaderera kugadzirisa kurongeka kwechikamu, muchina wekuchera migodhi ndeweIT7, uye zvekurima zvekurima. michina ndeyeIT8. Zvinoenderana nemabasa akasiyana ezvikamu zvechigadzirwa, iyo machining chaiyo inodiwa kuti iwanikwe yakasiyana, uye fomu rekugadzirisa uye maitiro akasarudzwa zvakare akasiyana. Iri bepa rinosuma machining echokwadi ekutendeuka, kugaya, kuronga, kukuya, kuchera, kufinha uye mamwe maitiro akajairika machining.
CNC Turning
Iyo nzira yekucheka iyo iyo workpiece inotenderera uye chishandiso chekushandura chinofamba mumutsara wakatwasuka kana curve mundege. Kutendeuka kunowanzoitwa pane lathe, iyo inoshandiswa kugadzirisa mukati uye kunze cylindrical nzvimbo, magumo zviso, conical nzvimbo, kuumba nzvimbo uye shinda dzebasa rekushanda.
Iko kutendeuka kwakaringana kuri IT8-IT7, uye kushata kwepamusoro ndeye 1.6-0.8 μ m.
1) Kutendeuka kwakashata kunotora kudzika kukuru kwekucheka uye chiyero chikuru chekudya kuvandudza kushanda kwekushandura pasina kuderedza kukurumidza kwekucheka, asi kururamisa kwekugadzira kunogona kusvika kuIT11 uye kuoma kwepamusoro ndeye R α 20-10 μ m.
2) Kumhanya kwepamusoro uye diki rekudya uye kudzika kwekucheka kunogamuchirwa kusvika pazvinogoneka kune semi kupedzisa kutendeuka uye kupedzisa kutendeuka. Kurongeka kwekugadzira kunogona kusvika IT10-IT7, uye kushata kwepamusoro kuri R α 10-0.16 μ m.
3) High-speed precision kutendeuka kweasina ferrous simbi mativi ane dhaimondi anotendeutsa chishandiso chakakwenenzverwa pa-high-chaiyo lathe inogona kuita kuti machining anyatsosvika IT7-IT5, uye kushata kwepamusoro iR α 0.04—0.01 μ m. Kutendeuka kwemhando iyi kunonzi "mirror turning".
CNC Milling
Kugaya kunoreva kushandiswa kwekutenderedza akawanda edge maturusi ekucheka maworkpiece, inova inonyatso shanda nzira yekugadzirisa. Inokodzera machining ndege, groove, akasiyana ekugadzira nzvimbo (senge spline, giya uye shinda) uye yakakosha nzvimbo yekufa. Zvinoenderana neyakafanana kana yakatarisana negwara rekumhanya kukuru uye workpiece feed direction panguva yekugaya, inogona kukamurwa kuita milling yekumberi uye reverse milling.
Kurongeka kwekugadzira kwekugaya kunogona kusvika IT8~IT7, uye kushata kwepamusoro i6.3 ~ 1.6 μ m.
1) The machining kururama panguva rough milling iri IT11 ~ IT13, uye pamusoro roughness iri 5 ~ 20 μ m.
2) Machining kururama IT8~IT11 uye pamusoro roughness 2.5~10 mu semi precision milling μ m.
3) Kurongeka kwekugadzira panguva yekunyatsogaya ndeye IT16 ~ IT8, uye kushata kwepamusoro ndeye 0.63 ~ 5 μ m.
Kuronga
Kuronga inzira yekucheka inoshandisa planer kugadzira yakatwasuka mutsara mutsara unodzoreredza mafambiro pane iyo workpiece, iyo inonyanya kushandiswa kugadzirisa contour yezvikamu.
Kurongeka kwekugadzira kwekugadzira kunogona kusvika IT9 ~ IT7, uye kushata kwepamusoro ndeye Ra6.3 ~ 1.6 μ m.
1) Roughing machining kururama kunogona kusvika IT12 ~ IT11, uye pamusoro roughness iri 25 ~ 12.5 μ m.
2) Iyo semi yekupedzisa machining kurongeka inogona kusvika IT10 ~ IT9, uye kushata kwepamusoro ndeye 6.2 ~ 3.2 μ m.
3) Iyo chaiyo yekupedzisa kuronga inogona kusvika IT8 ~ IT7, uye kushata kwepamusoro ndeye 3.2 ~ 1.6 μ m.
kugaya
Kukuya kunoreva nzira yekugadzirisa yekushandisa abrasive uye abrasive maturusi ekucheka zvakawandisa pane workpiece, inova yekupedzisa uye inoshandiswa zvakanyanya muindasitiri yekugadzira michina.
Kukuya kunowanzo shandiswa semi kupedzisa nekupedzisa, nekurongeka kweIT8~IT5 kana kutopfuura, uye kushata kwepamusoro kunowanzo 1.25~0.16 μ m.
1) Hushasha hwepamusoro hwekugaya chaiko ndeye 0.16~0.04 μ m.
2) Ultra precision kukuya roughness ndeye 0.04-0.01 μ m.
3) Kushata kwepamusoro kwegirazi kugaya kunogona kusvika 0.01 μ M pazasi.
Kuchera
Kuboora ndiyo nzira yakakosha yekugadzira gomba. Kuchera kunowanzoitwa pamichina yekuchera uye lathes, kana pamichina inofinha kana muchina wekugaya.
Kunyatsoita machining ekuchera kwakadzikira, kazhinji kunosvika IT10, uye kushata kwepamusoro kunowanzo 12.5 ~ 6.3 μ m. Mushure mekuchera, kudzoreredza uye kugadzirisa zvakare kunowanzo shandiswa semi kupedzisa uye kupedzisa.
Boring
Boring imhando yemukati dhayamita yekucheka maitiro anoshandisa chishandiso kukudza gomba kana imwe denderedzwa contour. Hurongwa hwayo hwekushandisa hunowanzo kubva pahafu yakaoma machining kusvika pakupedza. Chishandiso chinoshandiswa chinowanzova chinhu chimwe chete chinofinha (chinonzi boring bar).
1) Iyo inofinha yechokwadi yezvinhu zvesimbi inogona kazhinji kusvika IT9 ~ IT7, uye kushata kwepamusoro ndeye 2.5 ~ 0.16 μ m.
2) Kurongeka kwekugadzira kweiyo chaiyo kufinha kunogona kusvika IT7 ~ IT6, uye kushata kwepamusoro ndeye 0.63 ~ 0.08 μ m.
