MOULD FOR PRODUCING FLUTED GRINDING WHEELS Russian patent published in 1998 - IPC

FIELD: abrasive tooling industry. SUBSTANCE: mould has annular holder 1 with central cylindrical insert 2, jig disk 7 with hole forming members in the form of rods 7 with tapered head-pieces 9, annular plate 3 with frameworks 5 mounted in it by means of bolts 6 and nuts 4. End of each rod 8 at side of tapered head-piece 9 has end steps, jig disk 7 has bores 13. Mould is provided with flanged bushes 11 and pipes 10 made of resilient material with low coefficient of friction. Flanged bushes 11 are located on rods 8 in aforesaid bores. Pipes 10 are seated on rods 8 between end steps and end surfaces of flanged bushes 11. Bushes 11 are located for possible axial displacement, coming in contact with end surfaces of pipes 10 and their deformation. EFFECT: high efficiency. 1 dwg
