Method of grinding for a vertical type of double disc surface grinding machine for a brake disc

摘要: A double surface grinding method for a vertical type of disc machine in which upper and lower ground surfaces work like brake are simultaneously. The entire moving stroke the wheel includes an idle feed moves at specified speed from waiting position to detection start before contacting with surface; than end after then detects position; position. is set corresponding time where current rotation drive motor detected during increases value no-load condition up value.
