Daim ntawv qhia tswv yim rau CNC milling SS 304 hauv paus qhov chaw - cov khoom siv, cuab yeej, kev ua siab ntev, kev ua tiav saum npoo, tus nqi tsav tsheb thiab kev tshawb fawb hauv khw tiag tiag.

H1 - CNC milling SS 304 hauv paus qhov chaw: precision, DFM & nqi

CNC milling ntawm SS 304 hauv paus qhov chaw yog muaj nyob rau hauv fixtures, vaj tse thiab cov khoom siv tu cev. Hauv phau ntawv qhia no kuv muab cov khw muag khoom- cov lus qhia pov thawj, cov ntaub ntawv tshawb fawb luv luv tsis qhia npe, thiab SEO- cov lus qhia tus phooj ywg uas koj tuaj yeem ua tau rau hnub no - los ntawm cov cuab yeej thiab pub rau kev tshuaj xyuas thiab tus nqi tsav tsheb. Nyeem rau kev tsim-rau- tsim cov kev kuaj xyuas, kev ua siab ntev thiab daim ntawv txheeb xyuas kom txo tau lub sij hawm voj voog thiab seem.

H2 - Vim li cas SS 304 rau hauv paus qhov chaw? (cov ntaub ntawv tseeb + cuam tshuam rau machining)

Composition & corrosion kuj:Austenitic stainless, zoo corrosion kuj nyob rau hauv nruab nrab ib puag ncig; ua hauj lwm- hardens thaum lub sij hawm machining yog li txiav cov tswv yim tseem ceeb.

Machineability:Nruab nrab - tawv dua hlau; xav tau kev teeb tsa nruj, cov cuab yeej ntse carbide thiab cov dej txias txaus.

Hom kev siv:Lub hauv paus tshuab rau kev ntsuas, cov khoom huv huv, cov khoom siv hluav taws xob.

H2 - Tsim rau Kev Tsim Khoom (DFM) daim ntawv tshuaj xyuas (cov khoom ua tau sai)

Khaws cov phab ntsa tuab zoo ib yam kom tsis txhob muaj kev sib tsoo.

Ntxiv cov fillets (min 0.5-1.5 mm) rau hauv cov ces kaum kom txo cov cuab yeej nyob.

Tsis txhob me me sab hauv radii uas yuav tsum tau txiav tshwj xeeb; siv radii txuam endmill (piv txwv li, 3 mm radius → 6 mm endmill).

Qhia kom meej qhov tseeb kam rau ua (qhia):

General nta:± 0.10 hli

Qhov tseem ceeb mounting qhov / mating ntsej muag:± 0.02-0.05 hli

Flatness ntawm lub hauv paus:Tsawg dua los yog sib npaug li 0.05 hli tshaj 150 hli(yog tias xav tau, thov sib tsoo lossis lapping)

Hu rau qhov chaw tiav: xeev Ra lub hom phiaj (piv txwv li,Ra 0.8 µm).

H2 - Pom zoo tooling & txiav tsis (tus nqi khw muag khoom)

Cov no yog khw- cov ntsiab lus pib ib txwm - ib txwm txheeb xyuas nrog koj CAM/simulator.

Kev ua haujlwm	Tool	Ceev (m / min)	Pub rau tus hniav (mm/z)	DOC (mm)
Rough pocketing	Carbide ntsej muag zeb / 6-12 hli endmill	30-45m / min	0.05–0.12	1.0–3.0
Finishing (lub ntsej muag / contour)	Carbide 4-8 mm pob / tiaj tus	40-60m / min	0.02–0.06	0.2–0.5
Qhov drilling (HSS / carbide)	Twist / carbide	20-40m / min	-	-

Nco tseg:

Siv cov cuab yeej nruj thiab txiav lub teeb radial rau kev ua tiav kom txo tau kev sib tham thiab ua haujlwm -cov teebmeem nyuaj.

Siv los ntawm - cov cuab yeej coolant los yog dej nyab coolant rau stainless kom tsis txhob ua - nce ntug.

Rau kev sib sib zog nqus pocketing siv trochoidal milling kom cov cuab yeej koom ua ke zoo ib yam.

H2 - Fixturing, clamping & thermal xav

Clamp kom txo qis distortion: siv fij saum toj kawg nkaus clamps lossis lub tshuab nqus tsev rau cov hauv paus nyias.

Siv lub puab tsaig muag lossis cov khoom siv kho kom haum rau kev rov ua dua thaum tuav lub ntsej muag.

Cia qhov chaw kom ruaj khov tom qab machining ua ntej ntsuas qhov ntsuas - stainless tuav cov cua sov thiab dims qhov tseeb yog ntsuas kub.

H2 - Nto tiav & cov txheej txheem thib ob

Raws li -machined:Ra 0.8–3.2 µm raug nyob ntawm cutter thiab DOC.

Ncej - cov kev xaiv txheej txheem:hlaws blasting, electropolishing (txhim kho corrosion kuj & zoo nkauj), passivation (tshem tawm cov hlau dawb).

Plating / Txheej:feem ntau tsis tsim nyog rau 304 tshwj tsis yog tshwj xeeb hnav / inertness xav tau.

H2 - Kev tswj kom zoo & tshuaj xyuas

Cov kev kuaj xyuas tseem ceeb: qhov loj / txoj hauj lwm (CMM), flatness (nto phaj + dial), xov haum (gauge).

Kev pom zoo tshuaj xyuas txoj kev npaj rau kev tsim khoom:

Thawj tsab xov xwm CMM tsab ntawv ceeb toom (tag nrho cov tseem ceeb dims)

SPC sampling: 1 rau 50 rau nruab nrab khiav, 1 rau 10 rau nruj- cov khoom tiv thaiv

Nco tseg: qhia ntsuas qhov ntsuas kub (20 degree) thiab ntsuas txoj hauv kev hauv daim duab.

H2 - Tus nqi tsav tsheb & lub sijhawm ua haujlwm

Primary cost drivers:

Khoom siv:SS 304 phaj / ntawv nqe thiab tawm los (zes efficiency).

Lub sijhawm voj voog:ib feem complexity, tus naj npawb ntawm kev teeb tsa thiab qhov tob ntawm kev txiav.

Tooling:tshwj xeeb micro- cov cuab yeej lossis siab - ua haujlwm carbide nce nqi cuab yeej.

Ua tiav:electropolishing, passivation, sib tsoo ntxiv sijhawm / nqi.

Kev tshuaj xyuas:CMM thiab nruj SPC nce ib - tus nqi ib feem.

Lub sij hawm ua cov txheej txheem:qauv 5-15 hnub ua haujlwm; me me ntau lawm khiav (100-500 pcs) 2-6 lub lis piam nyob ntawm kev ua tiav thiab tshuaj xyuas.

H2 - Cov ntaub ntawv tshawb fawb luv luv tsis qhia npe

Qhov xwm txheej:Peb machined100SS 304 hauv paus qhov chaw (200 × 150 × 10 mm) siv los ua mounting daim hlau nrog 12 threaded inserts txhua.
Peb ua dab tsi:ib leeg- sab ntxhib + ua tiav hauv ob txoj haujlwm, kev cai mos- lub puab tsaig fixture, los ntawm - cuab yeej coolant, electropolish.
Cov txiaj ntsig (kwv yees):nruab nrab lub sij hawm voj voog14 feeb / ntu, seem<1%tom qab DFM hloov; zaum kawg flatness0.03mm ib; xa hauv18 hnub ua haujlwm.
Zaj Lus Qhia:txav me me sab hauv fillets kom phim tus qauv endmill thiab consolidating nta rau hauv ib qho kev teeb tsa lub voj voog lub sij hawm los ntawm ~ 22%.
