Abstract:
A device for relief grinding a blade having a radially outer edge of an elongated length and first and second faces, with the first and second faces extending generally radially from a reel axis, comprising:a rotatable grinding shaft defining a grinding wheel axis; a grinding wheel rotatable with and axially slideable along the grinding shaft to follow the elongated length of the blade, said grinding wheel including a hub with a first bearing surface; a grinding wheel guide assembly mounted for motion parallel to the grinding wheel axis on at least one rail that extends the elongated length of the blade and is substantially parallel to the grinding wheel axis; a guide finger adjustably supported on the grinding wheel guide assembly for contacting one face of the blade during grinding and holding the blade in position for relief grinding; and a first non-sliding stabilizer bearing supported on the grinding wheel guide assembly for bearing contact with the first bearing surface, said first stabilizer bearing oriented to apply to the first bearing surface forces applied to the grinding wheel guide assembly that include a component parallel to the grinding wheel axis.
