4. Bophahamo ba Lerako le Bophara ba Tšobotsi
Lithipa tsohle tsa rona li na le lithipa tsa carbide.Sesebediswa sena se thata haholo se fana ka bophelo bo botle ba lisebelisoa le tlhahiso ka ho kheloha ho fokolang.Leha ho le joalo, esita le lisebelisoa tse matla ka ho fetisisa li ka holofala, joalo ka litšepe, haholo-holo lipolasetiki tse ntseng li etsoa ka mechine.Ka hona, bolelele ba lerako le boholo ba likarolo li itšetlehile haholo ka geometry ea likarolo tsa motho ka mong le sesebelisoa se sebelisoang.Mohlala, botenya ba bonyane ba 0.020" (0.5mm) le botebo ba karolo e kaholimo ho 2" (51mm) li tšehelitsoe bakeng sa mochini, empa seo ha se bolele hore o ka rala sinki ea mocheso e kentsoeng ka litekanyo tsena.
5. Lathe ea sesebelisoa sa matla
Ntle le bokhoni ba rona bo pharaletseng ba ho sila, re boetse re fana ka lisebelisoa tse phelang tsa CNC turning.Lisebelisoa tse sebelisoang mecheng ena li tšoana le tse litsing tsa rona tsa mochini, ntle le hore ha re fetole likarolo tsa polasetiki hona joale.Sena se bolela hore masoba, li-grooves, lifolete le likarolo tse ling li ka etsoa ka mokhoa o ts'oanang kapa oa perpendicular (axial kapa radial) ho "axis e telele" ea sesebelisoa se fetotsoeng (Z-axis ea eona), 'me hangata li latela likarolo tsa orthogonal tse entsoeng mochineng. setsi Melao e tšoanang ea moralo.Phapang mona ke sebopeho sa thepa e tala, eseng sesebelisoa se ipehetseng.Likarolo tse fetotsoeng joalo ka li-shaft le lipiston li qala ho pota, ha likarolo tse emisitsoeng joalo ka manifolds, mabokose a gauge le likoahelo tsa li-valve hangata ha li sebelise li-blocks tsa lisekoere kapa tse kgutlonne.
6. Multi-axis milling
U sebelisa machining a 3-axis, workpiece e koetsoe ho tloha tlase ho stock e tala ha likarolo tsohle li khaotsoe ho tloha mahlakoreng a 6 a orthogonal.Boholo ba karolo e kholo ho feta 10 ″ * 7 ″ (254mm * 178mm), ho ka etsoa feela holimo le tlase, ha ho na tlhophiso ea lehlakore!Leha ho le joalo, ka ho siloa ha li-axis tse hlano, hoa khoneha ho sebelisa mochine ho tloha palo efe kapa efe ea likarolo tse seng tsa orthogonal.
