Embodiment 1
[0029] Prepared by the following method Double-sided sintered W-groove diamond tools. The manufacturing method of the W-groove diamond tool includes the following sequence: batching-simplification-secondary powder filling cold pressing-pressureless sintering-wiping sheet punching-painting-sharpening-inspection, packaging and storage.
[0030] 1) Ingredients of diamond and metal bond: expressed in weight percent, EXD606 alloy 30%, LFP alloy powder 10%, tin powder 8%, nickel powder 10%, cerium-copper alloy powder 1%, copper powder 41%. The diamond concentration added in the metal bond is 0.8ct / cm 3 , diamond particle size 35 / 40 accounts for 20%, 40 / 50 accounts for 50%, 50 / 60% accounts for 30%, mixed into molding materials, using a three-dimensional mixer, and the mixing time is 120 minutes.
[0031] 2) Simplified manufacturing: add the granulating agent to the mixed molding material for mixing and simple granulation.
[0032] 3) Cold pressing: Adjust the tooling mold, first ...
