Swarf sau nyob rau hauv cov kab noj hniav hauv pem teb, ua rau nti re- txiav, cov cuab yeej loj chatter, thiab ceev ceev aluminium vuam mus rau qhov kawg zeb. Nto roughness degraded yav dhau los Ra 1.6, thiab peb cov cuab yeej sib law liag thaum roughing.

· Dazao Txheej Txheem Hloov Kho:Hloov mus rau qhov siab -ester semi- hluavtaws formulation, nce active concentration mus rau 11%. Cov txheej txheem engineers rerouted xa khoom los ntawm 40 Bar Los Ntawm -Spindle Coolant kab haum rau parabolic-flute roughing tool.

· Cov txiaj ntsig kev ua haujlwm:Dynamic siab - cov kua dej ntws tawm tau tshem tawm cov chips tam sim ntawd los ntawm cov hnab ris sib sib zog nqus. Nto tiav txhim kho rau Ra 0.35, lub neej cuab yeej tau nce los ntawm 260%, thiab lub sijhawm voj voog poob los ntawm 22% los ntawm kev tshem tawm cov cuab yeej nruab nrab- tshem tawm cov kev tshem tawm, sib ntsib tag nrhopom zoo cov qauv hauv peb CNC phab ntsa thickness tsim phau ntawv qhia.

Case 2: Ntau lawm Tapping hauv AISI 316L Stainless Manifolds

· Cheebtsam Geometry:Fluid control manifolds xav tau 48 qhov muag tsis pom M3x0.5 threaded qhov, 9 mm sib sib zog nqus, hauv txias -tiav AISI 316L.

· Kev teeb tsa thawj zaug:General-lub hom phiaj 7% semi-synthetic flood coolant feeding standard cobalt-vanadium kauv-flute taps.

· Production Failure:Cov kais dej tau ntsib qhov hnyav micro- chipping ntawm cov npoo, ua tsis tau txhua txhua 40 txog 50 qhov. Xov pitch diameters fluctuated out of tolerance because of heavy material work-hardening in the hole.

· Dazao Txheej Txheem Hloov Kho:Hloov cov kab dej nyab sab nraud rau siab -siab synchronized tapping taub hau uas muab cov ester tshwj xeeb-raws li huab cua- siab (EP) zoo txiav cov kua dej los ntawm micro- xa tawm.

· Cov txiaj ntsig kev ua haujlwm:Xov nto tiav tiav chav kawm 6H ua raws yam tsis muaj micro- kua muag. Kais lub neej nthuav dav los ntawm 45 qhov mus rau ntau dua 210 qhov ntawm ib lub cuab yeej, txiav cov cuab yeej hloov pauv sijhawm los ntawm 78%.

Quality Assurance Cov Txheej Txheem: Tus Neeg Siv Khoom Muaj Peev Xwm Tshawb Fawb thiab Cov Ntawv Sau Txias DFM

Ua ntej kos npe tawm ntawm cov khoom xaj xaj kom nruj -kev siab ntev aerospace, kev kho mob, lossis tsheb sib dhos, pawg neeg tsim khoom yuav tsum ntsuas cov khoom lag luam muaj peev xwm tiv thaivpeb ntau lawm-qib CNC DFM daim ntawv tshuaj xyuas rau kev tsim khoom- npaj khoom:

DFM Coolant Accessibility Audit

Puas yog sab hauv qhov muag tsis pom tapping qhov tsim nrog cov nti nyem qhov tob (tsawg kawg 2x suab) los tiv thaiv cov kua dej hydraulic thiab cov kais dej tawg?

Ua lub hnab nqaim nqaim (qhov tob- rau- qhov dav qhov sib piv ntau dua 3: 1) tso cai rau lub cev kab - ntawm - pom kev pom kev siab rau - siab los ntawm - spindle txias?

Puas yog ib feem geometries tsis muaj cov hnab tshos uas ua rau cov kua dej tsis zoo, uas tuaj yeem ua rau micro-galvanic etching thaum kho cua sov tom qab lossis ntim khoom?

Tus neeg muab khoom Facility Coolant Audit

Puas yog lub chaw tsim khoom siv cov khoom siv sib faib ua ke rau cov dej - sib xyaw ua ke, lossis cov neeg ua haujlwm puas tso siab rau cov khoom ntim tsis sib xws?

Puas yog optical lossis digital refractometer tshuaj xyuas txhua hnub rau txhua qhov chaw CNC machining ntawm kab?

Puas yog lub tshuab cuab yeej cov khoom lag luam muaj cov khoom siv sib cais roj sib cais (disc skimmers, coalescers, lossis centrifuge systems)?

Puas yog dej purity conditioned los ntawm -site Reverse Osmosis (RO) los yog Deionization (DI) systems kom tswj tau cov ntxhia hardness hauv qab 150 ppm?
