Ukukhetha phakathi kokunyathela isitembu seshidi nemishini ye-CNC kungonga noma kumoshe amashumi ezinkulungwane zamadola. Le bhulogi ichaza amajika ezindleko, ukubekezelelwa, izikhathi zokuhola, kanye nekesi langempela lezingxenyekazi zekhompuyutha zasendlini yokugezela ukusiza abathengi benze izinqumo ezihlakaniphile.

Iningi labathengi nonjiniyela babhekana nempambano yemigwaqo ngesikhathi esithile: *Ingabe le ngxenye siyenza ngokugxiviza kwensimbi noma ngomshini we-CNC?* Khetha kusenesikhathi kakhulu (noma unamathele enqubweni engalungile isikhathi eside) futhi ungashisa amashumi ezinkulungwane zamaRandi kumathuluzi noma izindleko zeyunithi—kanye namaviki esimiso. Lesi sihloko sihlakaza umehluko ongokoqobo, ijika lezindleko zangempela, kanye nekesi lezingxenyekazi zekhompuyutha zasendlini yokugezela elibonisa lapho inqubo ngayinye ikhanya khona—ukuze ukwazi ukwenza ikholi ngokuzethemba.

Yini ngempela eqhuba isinqumo

Uma ususa amagama, ukukhetha kwakho kwehlela ezintweni ezinhlanu:
- Umthamo: zingaki izingxenye esikhathini esibekelwe
- Ukubekezelelana: ukuthi izilinganiso kufanele ziqine kangakanani
- Ubunzima: i-geometry, izici, nama-ops esibili
- Isikhathi sokuhola: ukuthi udinga ngokushesha kangakanani izindatshana zokuqala kanye nerempu
- I-Lifecycle: ukuthi umklamo uzoshintsha kangaki

Ukugxiviza kanye ne-CNC kokubili kungakhiqiza izingxenye zensimbi ezinhle kakhulu; inqubo “elungile” iyona ehambisana nalezi zinto ezingokoqobo—hhayi itiyori engcono kakhulu.

[Isiphakamiso sesithombe: I-Infographic ebonisa isitembu = phezulu phezulu + izindleko zeyunithi ephansi iqhathaniswa ne-CNC = azikho ngaphambili + izindleko zeyunithi ephezulu.]

Ijika lezindleko langempela (ngesiNgisi esilula)

- Ukugxiviza: Ukusebenzisa ama-US$6,000–$15,000. Ngemva kokuncishiswa imali, US$0.80–$2.00 ingxenye ngayinye ngevolumu ephezulu.
- CNC machining: Azikho izindleko zamathuluzi. Intengo yeyunithi ngokuvamile i-US$8–$25 kumaqoqwana amancane (50–500 pcs).

[Isiphakamiso sesithombe: Ishadi lomugqa elibonisa izindleko ingxenye ngayinye uma iqhathaniswa nevolumu, ukwehla kwejika lesitembu, i-CNC ihlala isicaba.]

Ukubekezelela kanye nejometri

I-CNC: ±0.002 ku-(0.05 mm) ejwayelekile. Ilungele izici ezinembayo kanye nejometri ye-3D eyinkimbinkimbi.
Ukugxiviza: ±0.005–0.010 kokujwayelekile. Ukubekezelela okuqinile kungenzeka ngama-ops esibili.

Umthetho wesithupha: izingxenye eziyisicaba, eziphindaphindayo → ukugxiviza; izingxenye ze-3D eziyinkimbinkimbi → CNC.

[Isiphakamiso sesithombe: Ithebula liqhathanisa ukubekezelelana eceleni.]

Isikhathi sokuhola nokuguquguquka

I-CNC: izingxenye ngezinsuku kuya kumaviki ama-2. Kuhle kakhulu kuma-prototypes nemiklamo ehamba ngokushesha.
Ukugxiviza: ukwenza amathuluzi kudinga amaviki angu-4-8 (ngezinye izikhathi amaviki angu-6-12). Kuhle kakhulu kumadizayini azinzile, anevolumu ephezulu.

Ikesi: Amakhava e-Stainless Steel Drain (I-Hardware Yasegumbini lokugeza)

Isimo A – 5,000 ama-pcs:
- Ukugxiviza: Ukusebenzisa ama-US$6,000–$15,000. Intengo yeyunithi US$0.8–$2. → Kushibhe ngaphezu kuka-50% sekukonke.
- CNC: Azikho izindleko zamathuluzi. Intengo yeyunithi US$8–$25. Izindleko zizonke ziphakeme kakhulu.

Isimo B - ama-300 ama-pcs:
- Ukugxiviza: Ukusebenzisa amathuluzi kusadingeka, akubizi kahle.
- I-CNC: US$8–$25 ingxenye ngayinye, ayikho ingozi yamathuluzi, ukulethwa okusheshayo.

Isiphetho: Ukugxiviza kuwina ngevolumu ephezulu. I-CNC ihlakaniphile kuma-prototypes noma ama-run amancane.

Izindlela ezisebenzayo zokugwema ukukhokha ngokweqile

1. Khiya izinqumo kuvolumu yangempela, hhayi izibikezelo.
2. Hlanganisa ukubekezelelana emsebenzini—hhayi umkhuba.
3. Yenza kube lula ijometri kusenesikhathi.
4. Qondanisa isikhathi sokuhola nobungozi bebhizinisi.
5. Cabanga umjikelezo wempilo: isibonelo → umshayeli wendiza → isikali.

[Isiphakamiso sesithombe: Isibonelo seshadi eligelezayo → umshayeli → isikali.]

Uhlu lokuhlola lomthengi osheshayo

- Ivolumu yonyaka kanye nenqwaba.
- Ukubekezelelana okubalulekile.
- Isethi yesici.
- Imikhawulo yesikhathi sokuhola.
- I-cadence yokubuyekeza.
- Qeda kanye nezinto ezibonakalayo (304 vs 316 ingenasici, ibhulashi vs isibuko).

A: Isukela ku-US$10,000 iye ngaphezulu kwama-US$200,000 kuye ngobunkimbinkimbi.

Q: Ingabe i-CNC ingakwazi ukushaya izikhathi zokuhola eziphuthumayo?
A: Yebo, izingxenye ezilula zingenziwa ngomshini ngezinsuku kuya kumaviki ama-2.

Umbuzo: Ingabe ukusuka ku-CNC uye ekugxivizeni kunzima?
IMP: Idinga izinguquko ze-DFM kodwa inguquko evamile, eyonga izindleko.

Okuthathwayo Okubalulekile Komthengi

1. Ivolumu inquma ukusebenza kahle kwezindleko: I-CNC iwina imigijimo emincane, isitembu siwina isikali.
2. Ukubekezelela komdlalo ekusebenzeni: I-CNC yokunemba, ukugxiviza kumakhava nabakaki.
3. Isikhathi sokuhola = ukuphathwa kwengozi: I-CNC yesivinini, isitembu somthamo ozinzile.
4. Inguquko yabathengi abahlakaniphile: I-Prototype ene-CNC, isikali esinesigxivizo.

Imicabango yokugcina

Ukukhetha phakathi kokugxiviza isitembu seshidi ne-CNC machining akukhona ukuthi iyiphi inqubo engcono emhlabeni wonke—imayelana nokuqondanisa inqubo nomjikelezo wempilo womkhiqizo wakho. I-Smart buyers prototype ene-CNC, iqinisekisa isidingo, bese ishintshela ekugxivizeni uma imiqulu ithethelela ukusetshenziswa kwamathuluzi. Ngenxa yochungechunge lokuhlinzekwa kwabantu abadala lwase-China, izindleko zamathuluzi nezikhathi zokuhola kuvame ukuncintisana kakhulu kunabahlinzeki baphesheya kwezilwandle. Uma unemidwebo ethile, zizwe ukhululekile ukufinyelela ekuhlaziyweni kwezindleko okufanelayo kanye nekhotheshini.
