EFFECT OF YJCS-5B POLISHING:
|
Appearance
|
after polishing, the surface should be flatly lapped; all EDM, wire-cut or milling marks should be removed.
|
Roughness
|
After EDM Erosion Stage 1, the surface roughness should be below Ra0.3. After complete ultrasonic finishing, the surface roughness should be around Ra0.012 (mirror finish).
|
Ultrasonic Finishing Speed
|
The speed may differ due to operator familiarity and working area complexity.
