摘要： A polycrystalline diamond is prepared by chemical vapor deposition (step 101). A surface of the polycrystalline diamond is metallized (step 102). The metallized surface of the polycrystalline diamond is grooved with a YAG laser (step 103). A wedge or the like is driven into the grooves of the polycrystalline diamond to pressurize the same, whereby the polycrystalline diamond is divided along the grooves (step 104). Alternatively, a surface of a polycrystalline diamond prepared by chemical vapor deposition is grooved with a YAG laser (step 112), and the surface of the polycrystalline diamond is metallized (step 113) after the grooving. The obtained diamond heat sink (10) includes a first layer (11a) grooved with a laser, and a mechanically divided second layer (11b). Graphite adheres to the outer peripheral surface of the first layer (11a). The outer peripheral surface of the second layer (11b) has a greater surface roughness than that of the first layer (11a).

摘要： A polycrystal diamond fluted tool is provided which is capable of effecting working with much higher accuracy and longer life as compared with the sintered diamond straight fluted tool of the prior art, and is particularly suitable for finishing working with high accuracy. The tool is produced by forming, by a vapor phase synthesis method, a polycrystal diamond film on the surface of a substrate which has been subjected to helical grinding, then subjecting the product to a chemical treatment to dissolve and remove only the substrate, brazing the resulting polycrystal diamond film in a fluted form to at least a part of the rake face of a tool base metal which has been subjected to helical grinding in a similar manner to the substrate, and then subjecting the brazed tool base metal to working of a flank face to form a cutting edge.
