Covington Tabletop 2 Head Sphere Grinder


The Small Sphere Machine makes spheres from 1/4" to 1" in size. Used for precision, this unit will take your work piece from a rough round shape to a perfect polished sphere. The downward slant of the cutter cups and shafts run the sphere in a continuous bath of grit eliminating the need to constantly dab grit on with a brush, and causing the grit slurry to run away from the bearings. The angle of the cutting cups can be increased as the rough corners of the sphere grind off, while a spring loaded head makes continuous adjustment unnecessary. Unit comes complete with one (1) grit pan, instructions, product guarantee, and one pair of 1/4", 3/8", 5/8", and 7/8" cutter cups. This unit is an excellent choice for restoring marbles to original condition.
