硬质合金具有高的硬度、良好的红硬性和强度,作为刀具材料,早已广泛应用于机械加工中。随着生产技术的发展,硬质合金刀具的使用方式也在不断发展变化。近年来出现了所谓不重磨机械夹固硬质合金刀具,这种刀具免去了焊刀手续,从而使硬质合金刀头内部不会 Carbide has high hardness, good red hardness and strength, as a tool material, has long been widely used in machining. With the development of production technology, the use of carbide cutting tools are also evolving. In recent years there has been the so-called non-re-grinding carbide chuck tool, this tool eliminates the need for welding procedures, so that the internal carbide tip will not
