The calculated spindle speed would be 12,732 rpm at a wheel diameter of 250mm at position 3.
When the maximum wheel spindle speed limit of 9,000 rpm is reached, it is not exceeded.
Important: To prevent the grinding wheel from exceeding 9,000 RPM, a
limit is placed on the grinding wheel spindle speed (described on page
12-42) with the G92 S9000; block.
