摘要： A base disk type grinding wheel for high speed grinding, wherein a base disk is made of a rapidly solidified aluminum alloy containing 15 to 40 wt % of Si, 0.5 to 6 wt.% of Cu, 0.2 to 3 wt.% of Mg, the remainder of the alloy being aluminum, wherein a plurality of grinding segment chips stuck to the peripheral surface of the base disk integrate a peripheral grinding wheel layer having superabrasives bound thereto and an inside peripheral abrasive grain layer having abrasive grains, which has a lower hardness than that of superabrasives, bound thereto with the same binding agent as that used in the peripheral grinding wheel layer and wherein the superabrasives are subjected to a heat treatment. In the grinding wheel, high stability of the strength of its base disk is exhibited due to the use of the above-mentioned material, and the segments can be stuck with ease and also a satisfactory decrease of the toughness of superabrasives can be achieved without detriment to its grinding characteristics.

摘要： The finding regards diamond cutting blades and discs, to be employed in the field of working stone such as granite, marble, limestone, basalt, lava stone, tufa, slate, sandstone, travertine and the like; the cutting of these materials occurs by means of the diamond tools (1) which, with the rubbing on the stone and due to abrasion, realises the required cut. Such blades and discs are characterised in that the diamond segments (3) composing the so-called "teeth" are attached in removable manner on the support (2), whether this is composed of a laminar body or a steel disc.

摘要： A drum grinding wheel includes an elongated drum configured for coaxial engagement with a spindle of a grinding machine. An exterior surface of the drum extends parallel to a central axis, and a plurality of removable cutters are removably fastened to the exterior surface. Each of the cutters has a plurality of ribs disposed in spaced relation thereon, and abrasive grain is disposed on a grinding face of each of the ribs, such as by use of a metallic braze.

摘要： The rotary tool for producing profiles or cuts in hard fragile materials such as marble, granite, stone, glass and the like comprises at least one rotationally symmetrical body (1, 2) involving a configuration defined by the envelope of a multiplicity of circular parts (6-13) externally provided with diamond means. The circular parts are separated by grooves (20 to 25) and the configuration corresponds as a negative of profiles or cuts to be produced in the above-mentioned hard fragile materials, the arrangement being such that the production of profiles or cuts is effected jointly by abrasion on the part of the diamond means and by fragile-fracture breaking on the part of the grooves, and possible breaker inserts (30) with a metal pin which is hard or covered with industrial diamond.

摘要： The invention relates to a grinding tool (10) for profiled strips made of wood comprising a base body (15), which can be rotationally driven and on which a base profiled body (13) made of an elastic material is placed in a rotationally fixed manner. In addition, the grinding tool is equipped with a grinding means (11) and should be designed as to distinctly reduce the tool costs without having to accept a reduction in quality of the profiled strips to be ground. According to the invention, a base profiled body (13) having a constant cross-section is used for the different cross-sections for the profiled strips to be ground. The base profiled body (13) comprises a cylindrical ring (13a) on which an outwardly directed, radial supporting ring (13b) is placed on at least one face end area. The cylindrical ring (13a) and the outwardly directed supporting ring (13b) are manufactured as a single piece from an elastic material. The inventive grinding tool (10) is particularly suited for the manufacturing of profiled strips by machining.
