Puas yog lub Hoobkas puas siv siab- spindles ceev (20,000-30,000RPM) nruab nrog High-Npaj Siab Los ntawm-Spindle Coolant (TSC Ntau dua lossis sib npaug rau 70bar) thiab MQL misting systems xav tau rau siab -kev khiav tawm ntawm txhuas nti?

3. Cov khoom siv hauv xov tooj cua

Puas yog lub ntsuas ntsuas ntsuas thermally tswj (20^∘C±0.5^∘C)? Puas yog tus neeg muag khoom ua haujlwm 3D Coordinate Measuring Machines (CMM) nrog kev sojntsuam sojntsuam muaj peev xwm txheeb xyuas qhov tseeb ntawm txoj haujlwm, profile tag nrho cov runout, thiab qhov roughness ntawm lub sub-micron daws teeb meem?

Xaus thiab Engineering Action Plan

Precisionaluminium cnc millingtso siab rau kev tswj xyuas kom zoo ntawm cov thermal, tshuaj, thiab cov khoom siv sib txawv. Los ntawm kev sib xyaw ua ke ntawm txhuas tempers (xws li kev qhia 6061-T651 rau kev ruaj ntseg kev ntxhov siab), suav rau anodizing zaj duab xis kev loj hlob thaum ntxov ntawm kev tsim qauv, siv 3-flute DLC-coated tooling, thiab ua raws li cov txheej txheem nruj DFM thiab phab ntsa tuab, pawg engineering tuaj yeem tsim cov khoom ua haujlwm siab ntawm cov nqi qis dua.

PRE- KEV KAWM NTAWV ENGINEERING checklist:

· Cov khoom siv temper xaiv (T651 teev rau cov hnab ntim hnyav).

· Internal vertical corner radii sized to R >= 1.1x cutter radius.

· Precision bores kho rau anodizing kev loj hlob (50/50 txoj cai siv).

· Wall thickness verified (>=0.8mm for short walls, >=1.5% qhov siab rau phab ntsa siab).

· 3-flute DLC coated cov cuab yeej thiab dynamic milling toolpaths xaiv.

· Kev lag luam kam rau ua tau teev tseg (ISO 2768-m) qhov kev nruj nruj tsis xav tau.
