Improve grinding wheel nodal density uniformity

Grinding wheel radial direction of the working layer pressing section of the block mold, the mold frame which comprises, disposed between the mold box, four through-holes in the four through-holes disposed above the upper bottom surface of the concave head, below the through hole of the Quartet set the top surface is convex head. By  polycrystalline diamond  aspect of the present utility model, compared with the axial pressing mold, the pressing mold using the radial direction has the following beneficial effects: 1. Along the radial direction of the grinding wheel  abrasive grinding  nodal arc suppression, which can effectively improve the grinding wheel nodal density  abrasive wheels , ensure wheel section of the block have reached all parts of the design density. 2. Mold cavity is four square structure, suppressing a short trip, reducing the pressure loss; superhard materials can effectively solve the grinding wheel working layer deformation, cracking problem, reduce waste generation, saving production costs.
