Milling nzira yekuguma mill
Muchigayo, zvigayo zvinokwanisa kupatsanurwa mumhando mbiri: kugaya pasi uye kumusoro, maererano nehukama huri pakati pekutenderera kwechigayo chekucheka uye nzira yekucheka chikafu. Kana iyo yekutenderera kutungamira kwekucheka milling kwakafanana neye workpiece feed direction, inonzi inokwira milling. Iyo yekutenderera nzira yekucheka milling yakatarisana neiyo workpiece feed direction, iyo inonzi up-cut milling.
Climb milling inowanzoshandiswa mukugadzirwa chaiko. Kushandiswa kwesimba kwekudzika pasi kudiki pane kuya kweup milling. Pasi pemamiriro akafanana ekucheka, kushandiswa kwesimba kwekugaya kuri 5% kusvika 15% kuderera, uye zvakare kunobatsira pakubvisa chip. Kazhinji, nzira yekudzika-milling inofanirwa kushandiswa nesezvinogoneka kuvandudza kupedzisa kwepamusoro (kudzikisa kushata) kwezvikamu zvemichina uye kuve nechokwadi chekurongeka kwedimensional. Nekudaro, kana paine dhizaini yakaoma, kuunganidza slag pane yekucheka pamusoro, uye pamusoro peiyo workpiece haina kuenzana, senge machining forging blanks, iyo up-milling nzira inofanirwa kushandiswa.
Panguva yekukwira, kucheka kunoshanduka kubva kune yakakora kusvika kune yakaonda, uye mazino ekucheka anocheka munzvimbo isina machine, iyo inobatsira pakushandiswa kwekucheka kwekucheka. Munguva yekukwira, kana mazino ekucheka ekucheka kwekucheka akabatana neworkpiece, haakwanise kucheka pakarepo musimbi yesimbi, asi anotsvedza chinhambwe chipfupi pamusoro peiyo workpiece. Zviri nyore kugadzira dhizaini yakaoma, iyo inoderedza kusimba kwechishandiso, inokanganisa kupedzwa kwepamusoro kweiyo workpiece, uye inounza zvisingabatsiri pakucheka.
Uye zvakare, panguva yekugaya, sezvo mazino ekucheka akachekwa kubva pasi kusvika kumusoro (kana kubva mukati kuenda kunze), uye kucheka kunotanga kubva pamusoro pevhu rakaomarara, mazino ekucheka anoiswa pasi pekuremerwa kukuru. uye mucheki wekugaya anogomara nekukurumidza, asi mazino ekucheka anocheka mukati. Hapana chinotsvedza chiitiko mukuita, uye tafura yekushanda haifambi panguva yekucheka. Kukwira kumusoro uye kudzika kugaya, nekuti kucheka ukobvu kwakasiyana kana uchicheka mukati meiyo workpiece, uye kureba kwekubatana pakati pemazino ekucheka uye workpiece kwakasiyana, saka iyo yekupfeka dhigirii yeguyo inocheka yakasiyana. Chiitiko ichi chinoratidza kuti kusimba kwechigayo chekupedzisira 2 kusvika ku3 yakakwirira pane iyo yekukwira kumusoro mukugayo pasi. nguva, kushata kwepamusoro kunogonawo kuderedzwa. Asi kukwira kukwirisa hakuna kukodzera kumilling workpieces neganda rakaoma.
