Abstract
A laminated rotary grinder including a parallity of thin grinding stone discs laminated together in an axial direction wherein the thickness of each of the discs is in the range of one to ten mm, the width of each space between each of the laminated discs is substantially within the range of 0.05 to 4 mm and the thickness of each of the discs is always greater than the space between discs.
Claims15
A laminated rotary grinder comprising a plurality of thin grindstone discs laminated together with an adhesive in an axial direction with a fixed space between each disc wherein the thickness of each of said discs is between 1 and 10 mm, the width of the fixed space between laminated discs is between 0.05 and 4 mm and the thickness of each disc is always greater than the spacing between discs.
A method of fabricating a laminated rotary grinder comprising:
- mixing inorganic particles of a uniform maximum diameter of between 0.05 and 4 mm with a thermosetting adhesive;
- spreading the adhesive containing the inorganic particles on grindstone discs having a thickness of between 1 and 10 mm;
- compressing the discs together to form a space between discs of between 0.05 and 4 mm;
- and
- firing the compressed discs to form a laminated rotary grinder.
A method of fabricating a laminated rotary grinder comprising:
- forming a plurality of discs with a projection having a thickness in the range of 0.05 to 4 mm on at least one surface of the disc;
- applying a thermosetting adhesive to the surface of the projection;
- compressing the discs together;
- and
- firing the compressed discs to form a laminated rotary grinder.
