Kev ua cov khoom yam ntxwv
Khoom sivTom ntej: Silicon Nitride Hardness HV1,850
Kev ua haujlwm nta: φ28 × 55mm complex 3D nto
Cov chaw thov: aircraft pem hauv ntej fairing, kub resistant bearings
Kev lag luam mob taw tes tsom xam
A. Cov yam ntxwv ntawm cov khoom sib tw
Silicon nitride ceramics, raws li lub siab tawv thiab hnav- cov khoom siv tiv taus, yog dav siv nyob rau hauv siab -kub aerospace Cheebtsam, tab sis lawv cov pob txha tsis tshua muaj zog ua rau cov txheej txheem ib txwm ua rau microcracks.
B. Ib txwm machining defects
① Cov cuab yeej hnav tus nqi yog 8 npaug ntawm cov hlau zoo tib yam
② 3D nto sib tsoo efficiency tsuas yog 2.3cm³ / h
③ Kev tawg ntau tshaj 35% (kev lag luam nruab nrab)
MIDSolutions core technology
Ultrasonic vibration tsib -axis machining center: 20kHz siab- zaus vibration txo txiav quab yuam
Supercritical CO2 cua txias system: -78℃qis kub suppresses cov khoom thermal stress
MQL Internal txias tshuab: 0.05ml/h micro-lubrication txo cov cuab yeej adhesion
