摘要： Method for welding cutter-segments characterized by focusing an electron beam or a laser beam on the boundary between a carbon-steel core body (7) and segments (1). Each segment is formed by a Co (cobalt) powder compact, containing diamond or CBN grit, which has been sintered to nearly 100% apparent density. The boundary may or may not have Ni (nickel)-filler. In cases of bond materials other than Co, the segment (1) has a structure of double layers (4, 5), one layer of which is composed of a powder compact, containing diamond or CBN grit, which has been sintered to nearly 100% apparent density, and the other layer (5) of which is composed of a sintered Co powder compact without any grit. The carbon-steel core body (7) welded by the above-mentioned method is thereafter tempered at 350.degree.-450.degree. C. if necessary. A steel core having no slot at its periphery may be used as the core body.

摘要翻译： 用于焊接切割器段的方法，其特征在于将电子束或激光束聚焦在碳钢芯体（7）和段（1）之间的边界上。 每个段由具有金刚石或CBN砂粒的Co（钴）粉末压块形成，其已被烧结到几乎100％的表观密度。 边界可以具有或不具有Ni（镍）填料。 在Co以外的键合材料的情况下，片段（1）具有双层结构（4,5），其一层由包含金刚石或CBN砂粒的粉末压块构成，其已被烧结到接近100 ％表观密度，另一层（5）由没有任何砂粒的烧结的Co粉末压块组成。 然后，如果需要，通过上述方法焊接的碳钢芯体（7）在350〜-450℃下回火。 可以使用在其周边没有槽的钢芯作为芯体。

摘要： A rotary blade has a rotary substrate with chips disposed about the outer edge of the substrate. The substrate further has two sets of semicircular slits. The first set of semicircular slits is disposed annularly about the rotary substrate on a circle coaxial with the center of rotation of the rotary blade. The semicircular slits open toward the center of rotation. The second set of semicircular slits are disposed on a circle inside of the circle of first slits. These slits open outwardly, thus blocking, at least partially, the first semicircular slits from the center of rotation. A filler material is filled into the semicircular slits, the slits thus providing a vibration damping effect. The chips may be attached to the outer edge of the rotary substrate by concave profiled cassette stands.
