Carbide
Carbide e lula e le matla nako e telele. Le hoja e ka 'na ea e-ba brittle ho feta lisebelisoa tse ling tsa ho qetela, re bua ka aluminium mona, kahoo carbide e ntle. The downside kholo ka ho fetisisa mofuta ona oa ho qetela leloala bakeng sa CNC hao ke hore ba ka fumana pricey. Kapa bonyane ba theko e boima ho feta tšepe e phahameng ka potlako. Hafeela u ntse u e-na le lebelo le lijo tsa hau tse kentsoeng, li-mill tsa carbide li ke ke tsa fokotsa aluminium feela joaloka botoro, li tla tšoarella nako e telele. Fumana matsoho a hau holim'a lifeme tse ling tsa carbide mona.
Liaparo
Aluminium e bonolo ha e bapisoa le litšepe tse ling. Ho bolelang hore li-chips li ka koala phala ea lisebelisoa tsa hau tsa CNC, haholo-holo ka ho itšeha ho tebileng kapa ho thella. Liaparo tsa li-mill li ka thusa ho fokotsa mathata a ka hlahisoang ke aluminium e khomarelang. Liaparo tsa Titanium aluminium nitride (AlTiN kapa TiAlN) li thella ka ho lekaneng ho thusa ho boloka lichipisi li tsamaea, haholo-holo haeba u sa sebelise se pholisang. Hangata sena se sebelisoa ha ho sebelisoa carbide tooling. Haeba u sebelisa lisebelisoa tsa tšepe tse phahameng ka potlako (HSS), sheba liaparo tse kang titanium carbo-nitride (TiCN). Ka tsela eo u fumana lubricity e hlokahalang bakeng sa aluminium, empa u ka sebelisa chelete e nyane ho feta ka carbide.
Geometry
Boholo ba machining a CNC bo mabapi le lipalo, 'me ho khetha leloala la ho qetela ha ho fapane. Le hoja palo ea liphala e le ea bohlokoa ho nahanoa, geometry ea lekolilo le eona e lokela ho nkoa. Liphala tse phahameng tsa helix li thusa haholo ka CNC chip evacuation, hape li thusa ka mokhoa oa ho itšeha. Lijeometri tse phahameng tsa helix li na le khokahano e ts'oanang le mosebetsi oa hau… ho bolelang hore seha se seha ka litšitiso tse fokolang.
Ho seha ho senyehileng ho thata bophelong ba lisebelisoa le pheletsong ea bokaholimo, ka hona ho sebelisa li-geometries tsa helix tse phahameng ho u fa monyetla oa ho lula u tsitsitse le ho tlosa lichifi tsa mochini oa CNC kapele. Likhatiso tse sitisoeng li baka tšenyo likarolong tsa hau. Video ena e bonts'a hore na likheo tse sitisoang ka leloala le chepiloeng li ka ama maano a hau a ho itšeha.
