Grindstones are usually made from sandstone.[2][3] Grindstone machines usually have pedals for speeding up and slowing down the stone to control the sharpening process.

The grinding stone is urged in the one direction extending radially of the axis against the stone to press the cam surface radially inward against the cam surface for contact of the stone surface along a line with the cam surface so that the stone moves in a radial direction as the camshaft rotates.

Single disk grinding machines use a rotary table to mount the parts while usually a vertical spindle grinding wheel is grinding the parts. On the same machine and using the same rotary table, also two spindles can be mounted, e.g. for coarse grinding and for fine grinding.
