How to choose the grinding amount of internal grinding?
The speed of grinding wheel of internal grinder is limited by the diameter of grinding wheel and the speed of grinding head. It is usually 15-25m/s. Where possible, a higher grinding speed should be used.
Internal grinder workpiece speed is generally 15-25m/min. When the surface roughness requirement is high, the small value is used, When the rough grinding or the combined area between the grinding wheel and the work piece is larger, the large value is used.
The vertical feed speed is generally 1.5-2.5m/min during coarse grinding, and it is 0.5-1.5m/min during the fine grinding.
Coarse grinding depth is generally 0.01-0.03mm, 0.002-0.01mm for refining, A few times light grinding need to be done after each feeding, more times will be done for fine grinding.
