组合式切削刀具的制造有许多方法:钎焊焊接、堆焊和真空扩散焊接。后者与其它方法相比其刀片与刀体的连接质量更高。但为此需用特殊的装置在真空或气体保护介质中加热连接部位(旨在消除氧化过程,因为工件要加热相当长的时间,并且在其磨过的和仔细清理过的接触面上要施加一定的压力)。此外,为了降低刀片和刀体材料热膨胀系数的差异对连接质量的影响(尤其是焊接硬质合金刀片时),
There are many ways to make a composite cutting tool: brazing, surfacing and vacuum diffusion welding. The latter has a much better connection of the blade to the blade than the other methods. However, for this purpose special means are required for heating the connection points in a vacuum or gas-protective medium (aimed at eliminating the oxidation process, since the workpieces are heated for a considerable period of time and are applied on their ground and carefully cleaned contact surfaces Some pressure). In addition, in order to reduce the influence of the difference in thermal expansion coefficient between the blade and the body material on the quality of the connection (especially when welding a cemented carbide insert)
