Zergatik garbitu beharko luke zuzentasuna? Polizazioaren helburu nagusia bikoitza da. Lehenengo, moldearen argitasuna handitzea eta lanaren itxura estetikoa hobeto dezake. Bigarrenik, moldea erosteko erraza dezake. Hurrengoan, EMAR eramango zaitu zehaztasun-estampatzeko polizazio metodoak arruntak ulertzeko.
1. Poliziazio mekanikoa: poliziazio mehanikoa gaitasun leun bat poliziatzeko metodo bat da, konbeko zatiak deformazio-prozesuetan poliziatzeko, zehaztasun-estampazio eta gaitasun-deformazio plastikoak moztea bezala. Gainerako kalitate handiko beharrezko lanak estampatzeko zehaztasun-zehaztasun-poliziazioa erabil daiteke. Gainerako poliziazio zehaztasun-zehaztasun-poliziazioa erabil daiteke grabatzeko tresnak bereziki diseinatuak dituzten grabatzeko tresnak, laneko gaitasunaren aurka estu-estu sakatzen dira, era
2. Electrolytic polishing: Precision stamping molds can be smoothed by removing small protrusions on the material surface through electrolytic polishing. Compared with chemical polishing, it can eliminate the influence of cathodic reactions and achieve better results.
3. Ultrasonic polishing: Place the material to be polished into a grinding suspension and place it together in an ultrasonic field. Then, through the oscillation of ultrasonic waves, the abrasive is ground and polished on the surface of precision stamped workpieces. Ultrasonic processing has low macroscopic force and will not cause deformation of the workpiece, but it will make the production and installation of precision stamped workpieces more difficult. Ultrasonic processing can be combined with chemical or electrolytic methods. On the basis of solution corrosion and electrolysis, ultrasonic vibration is applied to stir the solution, causing the dissolved products on the surface of the workpiece to detach and the corrosion or electrolyte near the surface to be uniform; The cavitation effect of ultrasound in liquid can also suppress the corrosion process, which is beneficial for the surface brightening of precision stamped workpieces.
