摘要： Die Schleifscheibe (2), die insbesondere zum Tiefschleifen bestimmt ist, weist einen ersten Schleifbelagteil (5) auf, der feinkörnige Diaman­ten enthält sowie einen weiteren Schleifbelagteil (9), der größere Diamantkörner enthält. Dabei kann es sich handeln um eine Umfangsschleifschei­be wie auch um eine Topfschleifscheibe. Bekannte Ausführungsformen solcher Schleifscheiben lassen entweder die geforderte Oberflächenrauhheit nicht erreichen oder weisen einen hohen Verschleiß auf, da sie nicht fortlaufend im Außenrandbereich der Stirnfläche einen hohen Diamantanteil als Schutz gegen eine Abrundung der Außenkante be­sitzen. Um dem abzuhelfen ist vorgesehen, daß der Schleifbelagteil (9) mit parallel zu der Drehachse der Umfangsschleifscheibe einschichtig angeordneten Diamantkörnern größerer Klassifizie­rung versehen ist, wobei die Diamanten senkrecht zu der Drehachse mehrschichtig angeordnet sind und sich gegenseitig berührend in einer galva­nisch niedergeschlagenen Bindung (10) gehalten sind.

摘要： An abrasive article has an abrasive portion with an organic bond and abrasive particles. The abrasive article has a non-abrasive portion (NAP) mounted to the abrasive portion. The NAP includes molding compound (MC) having chopped strand fibers (CSF). The CSF can be coated with a thermoplastic coating having a loss on ignition (LOI) of at least about 2.4 wt %, and the NAP having no abrasive particles. The NAP can include an MC having no abrasive particles with a MOHS scale hardness of at least about 9. The NAP may include CSF coated with a primary coating and a secondary coating on the primary coating. The NAP may have an outer diameter that is at least half of but not greater than an outer diameter of the abrasive article.

摘要： A through hole (H) is obtained in a glass plate (L) by engaging a drilling tool (D) on the glass plate (L) only from one side of the plate. The drilling tool (D) is rotated around its axis (A) while at the same time it is imparted with an axial movement of advancement through the glass plate (L) and with a planetary movement of rotation around a main axis (A1) which is parallel and spaced apart with respect to the axis (A) of the tool. As a result, the drilling tool (D) advances through the glass plate (L) by performing a helical movement. Once a hole (H1) is formed through the glass plate (L), the diameter of the hole (H1) is enlarged until reaching the desired diameter by a milling operation of the wall of the hole (H1). This milling operation can be carried out by using the same drilling tool (D). To this end, the tool has a front abrasive surface (40) of a substantially spherical shape, for performing the first drilling stage, and an axial stem (3) having an abrasive surface with a grain size smaller with respect to that of said front surface (40), which is used for performing the second milling stage.

摘要： A multi-abrasive tool is constituted by a support on which abrasive elements are present. Such abrasive elements are arranged in a manner so as to form one or more paths along which the successive abrasive elements have grain size sequentially increasing or decreasing by an arbitrary quantity when passing from on element to the next. Such principle gives rise to abrasive tools with different conformation both for polishing machines and for grindstones. For roto-orbital and planetary polishing machines, and optionally orbital, such support is circular and the grain sequence is circumferential, or radial, or in both directions. A first tool is constituted by contiguous (or non-contiguous) circular rings, that are differently abrasive. A second tool comprises differently abrasive elements arranged along the circular peripheral edge. A third tool comprises differently abrasive elements arranged along a spiral path of 360° starting from the edge. A fourth tool comprises two 180° spiral paths with reversed roughness sequences. A fourth tool comprises pairs of differently abrasive small cylinders fixed to a plate on concentric circumferences. A fifth tool is obtained directly on the plate of the polishing machine by means of reliefs and spacers for fixing differently abrasive sectors. For linear polishing machines, the abrasive support is a belt along which differently abrasive rectangular or oblique zones follow each other. For alternative polishing machines, the abrasive support is a plate shaped like the aforesaid belt. For tools to use with grindstones, the multi-abrasive element has a cylindrical rotation symmetry, or conical with rounded tip, or spherical symmetry.
