    • An explosive laminated cutting tool (10) which provides a self-sharpening edge. The improved cutting tool is preferably comprised of two softer metals (14, 16) adhered to a hard central layer (12) forming the cutting edge, with the central layer being made of such a material as tungsten carbide. The central laminate layer (12) is preferably perforated (18, 20, 22) to allow the outer layers (14, 16) to fuse through the perforations (18, 20, 22) to adhere to one another, thus creating a strongly bonded laminated cutting structure which may be self-sharpening. A method for manufacturing the cutting tool is also described. Another embodiment comprises a laminate wherein one of the layers has a plurality of recesses (41) in the surface facing another layer. The recesses (41) are filled with particles (40) such as tungsten carbide or diamond. When the layers are explosively welded together, the particles are fused in the weld area.
    • 一种提供自磨边缘的爆炸层压切割工具(10)。 改进的切削工具优选地由粘附到形成切削刃的硬质中心层(12)上的两个较软的金属(14,16)组成,中心层由诸如碳化钨的材料制成。 优选地,中心层压层(12)穿孔(18,20,22)以允许外层(14,16)通过穿孔(18,20,22)熔合以彼此粘附,从而产生强粘合 层压切割结构可自磨削。 还描述了用于制造切削工具的方法。 另一个实施例包括层压板,其中一个层在面向另一层的表面中具有多个凹部(41)。 凹部(41)填充有诸如碳化钨或金刚石的颗粒(40)。 当这些层被爆炸地焊接在一起时,颗粒在焊接区域熔化。
