Ntau npaum li casCNC MachiningNqi?
Ntawm $15 thiab $15,000. Nyob ntawm seb koj ua dab tsi.
Kuv ua hauj lwm procurement thiab project coordination ntawm ABIS Mould. Cov lus nug no tuaj txog peb zaug hauv ib lub lis piam los ntawm engineers uas xav tias CNC nqi ua haujlwm zoo li Amazon.
Cov Formula
Tus Nqi Tag Nrho=(Cov Khoom Siv + Lub Sijhawm Ua Haujlwm × Tus Nqi Teev Sijhawm) × 1.2
Lub 1.2 npog nyiaj siv ua haujlwm -QC, cov ntaub ntawv, kev tswj qhov project. Qee lub khw siv 1.15, qee qhov mus 1.3. Peb cov ntab ntab nyob ntawm txoj haujlwm nyuaj.
Lub sijhawm ua haujlwm:
Lub Sijhawm Yooj Yim=Txiav Length ÷ (Pib Tus Nqi × Spindle Speed)
Rau kev xa cov haujlwm tshwj xeeb, peb suav:
- Txiav ceev:Vc=(π × D × n) / 1000, qhov twg D yog workpiece txoj kab uas hla hauv mm, n yog spindle RPM
- Ib lub sijhawm dhau mus:T=(60 × L) / (f × n), qhov twg L txiav ntev, f yog pub rau ib lub kiv puag ncig
- Stepped ncej lub sij hawm:muab ntau los ntawm tus lej hla
- Grooving / Facing: T = 60 × (D1 - D2) / (2 × f × n) × N
Cov qauv no tseem ceeb vim tias "yooj yim" 20-feeb txiav txoj haujlwm dhau los ua 45 feeb ntawm lub sijhawm tshuab thaum koj ntxiv cov cuab yeej hloov pauv, hloov pauv, thiab qhov sib txawv ntawm qhov simulation thiab kev muaj tiag.
Peb lub khw tus nqi hauv RMB (USD hloov pauv kwv yees):
| Khoom siv | RMB/hr | USD/hr |
|---|---|---|
| Phau ntawv tshuab dhos (C6136 / C6140) | 60 | ~8 |
| CNC tshuab dhos | 60-120 | 8-17 |
| 3-axis tshuab | 60 | ~8 |
| Machining chaw | 60-120 | 8-17 |
| Hlau EDM qeeb | 60-150 | 8-21 |
| Hlau EDM los ntawm cheeb tsam | 0.06-0.08 / hli | - |
| Txim erosion | 80-150 | 11-21 |
| Nto grinder | 60 | ~8 |
| Fitting / sib dhos | 80 | ~11 |
Cov khw hauv Asmeskas khiav 4-6 × cov lej no. Ib tug 3-axis VMC ntawm $8-12/teev no raug nqi $50-75/teev hauv Ohio, $90-120 hauv California.
Nyiaj txiag tsis xav kom kuv tshaj tawm qhov no. Tab sis kuv nkees ntawm cov neeg siv khoom pom nrog tus nqi xav tau raws li kev xav.
Txoj cai ntawm tus ntiv tes xoo uas tau tuav:txhua $1,000 tshuab nqi ≈ $1/teev tus nqi khiav hauj lwm.Ib $500K 5-axis Mazak xav tau $100+/teev kom tawg txawm tias tom qab depreciation, tu, tooling, nyiaj ua haujlwm. Cov khw tshaj tawm $ 60 / teev rau 5-axis tab tom khiav cov cuab yeej siv thaum ub los yog qhia tsis tseeb txog kev muaj peev xwm.
Cov nqi no xav tias cov neeg ua haujlwm khiav 2-3 lub tshuab ib txhij nyob rau lub sijhawm ntev. Kev mob siab rau- kev teeb tsa nyuaj, kev ua siab ntev, kev daws teeb meem qauv-ob npaug ntawm tus nqi zoo.
Txhim kho Economics
Cov neeg siv khoom lub lim tiam dhau los xav tau tsib pawg. Ib qho yooj yim, tej zaum $ 12 txhua lub sijhawm ua haujlwm. Nqe $85 rau ib thooj. Nws dai.
Txhim kho kev teeb tsa:
- CAM programming, post-processing, simulation: 30 min – 3 teev
- Tooling xaiv / loading: 15-45 min
- Ua Haujlwm: 20-60 min
- Thawj tshooj + ntsuas: 15-30 feeb
- Kev hloov kho: txawv
Nws bracket: 2.5 teev teeb, ~ $ 300 ntawm tus nqi thauj khoom. Muab faib los ntawm 5=$60/piece hauv kev teeb tsa ib leeg.
| Qty | Teeb / Daim |
|---|---|
| 1 | $150-300 |
| 5 | $60-120 |
| 25 | $12-24 |
| 100 | $3-6 |
| 500+ | <$1 |
Ntawm 100 daim nws tau them $ 15 txhua. Tab sis 5 nqi dab tsi 5 nqi.
Batch koj prototypes. Peb tus qauv tsim ntawm ib qho PO qhia lub sijhawm teeb tsa-40% kev txuag hauv qee kis.
Programming nqi ntawm kev txiav txim rov qab: yuav tsum tsis muaj. G-code zaum ntawm lub server. Peb tau programmed ib zaug. Yog tias koj tus neeg muag khoom tau them qhov no ntau zaus, lawv tsis muaj peev xwm lossis siv koj.
Cov txheej txheem xaiv qhov pib
Ntawm no yog cov khw sib cais:
- Qhov nyob hauv qab ± 0.05mm:txheem milling yuav tsis txiav nws -CNC lossis hlau EDM yuav tsum tau
- Los ntawm - qhov ncej - hardening:xaim EDM nkaus xwb
- Qhov muag qhov muag tom qab- hardening:ntxhib ua ntej tshav kub kho, ua tiav tom qab
- Slots hauv qab 2mm dav:kab EDM

- Ua ntej- hardening rough pub:yam tsawg kawg nkaus 0.4mm
- Tsis yog - hardened rough pub:0.2 hli
- Plating thickness:feem ntau 0.005-0.008mm- tshuab rau pre-plating qhov ntev
Txhua qhov kev hloov pauv no ntxiv tus nqi. Tsim ib puag ncig lawv thaum ua tau.
Txheem drilling qhov tob ua ntej tus nqi nce:
- Li qub: 4 × diam
- Extended: 6 × txoj kab uas hla
- Qhov tob (khoom): 10 × txoj kab uas hla
Xov ntev tshaj 1.5 × txoj kab uas hla ntxiv xoom lub zog tab sis tseem ntxiv tus nqi. Qhov dig muag qhov xov xav tau 0.5-1.5 × txoj kab uas hla unthreaded hauv qab rau kais dej.
Yam tsawg kawg nkaus xov loj rau txhim khu kev qha ntau lawm: M6. Cov kais dej me me tawg.
