Scraping is the use of scraper, reference plate, measuring tools and developer (such as Prussian blue), through manual operation to quantitatively remove the material (single scraping amount of 0.002-0.01mm), repeated research point detection and scraping corrections, so that the workpiece to achieve flatness<=0.003mm / ㎡, contact spots>=20 points / 25 × 25mm ², sifas brutality RA0.4-0.8μm e konsa sou.Ultra-Precision Machining pwosesis nan kondisyon pwosesis.
Aplikasyon
Grate ak 0.01 - 0.05mm karakteristik mikwo-pwosesis, nan rèd la segondè nan pwosesis la sifas ak iranplasabl, aplikasyon pou komen li yo se sa ki annapre yo:
1. Machine Zouti Guideway vis: V - Kalite Guideway Rightness koreksyon a 0.005mm/m, zòn kontak pi gran pase oswa egal a 75%.
2. Inite turbine idwolik vyolans mozayik: reyalize 0.02mm diferans epesè ant milti - règleman an chaj mozayik
3
4.Aero - Magazin Engine: Elimine 0.03mm Deformation Estrès Asanble.
Wòl nan Gratian
Atifisyèl Gratian se youn nan metòd yo nan pwosesis reparasyon avyon, objektif li se diminye valè a brutality sifas, amelyore presizyon nan kontak ak presizyon jewometrik, konsa tankou amelyore zouti nan machin ak etablisman nan rèd la an jeneral anfòm, pèfòmans wilaj, efikasite mekanik ak lavi sèvis; Si sèlman ak sifas fanm k'ap pile machin ak gid fanm k'ap pile pwosesis machin se difisil a reyalize pi bon rezilta yo.Acrate Atik se pi plis segondè - zouti machin klas ak ekipman ak plak fè jete, zouti mezire presizyon nesesè.
