The tip angle of a center punch should be about 60 degrees, this ensure it will work correctly and have a long life expectancy.
When sharpening, the grinder wheel must turn in such a manner where it'll pull the material away from the tip. Ensure that you flip the chisel over to keep the tip centered and be careful not to overheat it so it does not wreck the temper of the metal. Also when sharpening, move the chisel along evenly on the grinding wheel which ensures even wear on the grinding wheel.

Once finished you should be left with something such as this and the chisel is now ready to be used.
