摘要： A tool with tool elements, rotating grinding and/or sanding tool is provided. The tool consists of a tool portion and a mounting portion, which secures the tool elements in the tool. The tool is distinguished in that the tool portion comprises first mount, and the mounting portion includes second corresponding mount for engaging with the first mount. The first and second mount include one or more resilient tabs, each of which is provided with at least one barb, and furthermore the mount comprises one or more recesses. When the tool portion and the mounting portion are assembled, the barbs on the resilient tabs will lock in the recesses of the mounting portion which are designed for this, locking the tool portion and the mounting portion to each other.

摘要： A tool for fine machining surfaces has a working medium carrier with a top face and a bottom face, wherein the bottom face is an attachment side. A set of individual exchangeable strip-shaped lamella holders are provided that each have one or more lamellas in individual or bundled arrangement. The lamellas each are oriented away from the attachment side of the working medium carrier and form in a downward direction remote from the attachment side a common working plane. The lamella holders on a side facing the attachment side are provided with first hooking members and the attachment side of working medium carrier is provided with second hooking members complementary to the first hooking members. The first and second hooking members are joined to each other in a direction perpendicular to the attachment side.

摘要： The abrasive unit contains a carrying disc (A) with a hub (1) set off in the central zone, having a coaxial hole (2) reinforced with a steel flange sleeve (3) for mounting the abrasive unit on the spindle of the angular hand grinder. The lower edges of numerous abrasive flaps (B) are fixed with glue binders (5) on the ring surface of the near-edge zone (4), the abrasive flaps subsequently overlapping one another in the circumferential direction so that their rear edges are exposed. The wheel of the carrying disc (A) is a layered polymer composite with reinforcement consisting of at least two meshes of glass fibre situated on both frontal surfaces of the carrying disc (A). The meshes are bonded by a composite matrix containing a binder of a thermosetting synthetic resin, a fine-grained material in the form of inorganic, mineral or synthetic loose material, particularly quartz, calcareous, carbonaceous or polymineral sand, industrial or quarry dusts, blast furnace or copper slag, or a mixture of the aforementioned materials and for which the natural or crumbled grain size ranges from 0.06 to 2.0 mm and the hardness according to the Mohs scale ranges from 3 to 7.

摘要： A rotary tool containing a core hub with helical groove on its outer surface filled in with continuous abrasive filament formed by folding of a pre-cut abrasive sheet including multiple bristle like straps extending radially from the hub. The method of manufacturing includes the steps of providing a hub, and forming a helical groove with inverted V-shaped cross-section along its cylindrical surface. An abrasive element is wound around the hub so that the folded edge is fed in the V-grove and is buckled inside the groove providing, along with securing it by sufficient pre-tension of the abrasive element, a secure anchoring of the abrasive element through locking of the buckled edge. The abrasive filament is formed from a roll of abrasive cloth as one continuous piece using a cutting operation and is provided with center-line perforations. These perforations assist folding the filament by providing it with discrete and desired flexibility as well as weakening it in such way that it assists the process of folded edge buckling inside the groove during winding and therefore forms a tight anchoring junction with the hub without need for an adhesive.

摘要： A first member has a base plate 11 and an abrasive sheet installation portion 12 where an abrasive sheet is fixed. The base plate or the abrasive sheet installation portion is provided with an air-introducing portion 15 as a space penetrating from the back face side to the front face side of the base plate or the abrasive sheet installation portion, and an airflow passes from the back face side to the front face side as a rotary abrasive material rotates. When the first member is used as a single unit, overheating is prevented and swarf can be removed when the rotation of a projection portion as the abrasive sheet installation portion 12 generates an airflow flowing through the air-introducing portion 15. Further, when a second member is provided such that its axial position is adjustable relative to the first member, an abrasive sheet of the second member can project and retract against the first member, so that, depending on processing required, grinding work can be performed by easily switching abrasive sheets to be used.

摘要： A combination between a grinding ring and a grinding wheel is disclosed, wherein the grinding ring has a centrally defined hole, a tubular extension extending from a periphery defining the hole, an annular extension extending from an outer periphery of the tubular extension, a skirt formed adjacent to the annular extension, teeth formed by pressing at a joint between the annular extension and the skirt and barbs each formed on a free end of the teeth. The grinding wheel is made of cloth so that the teeth together with the bars are able to extend into the grinding wheel when the skirt is pressed and engagement between the grinding ring and the grinding wheel is enhanced by applying an adhesive.

摘要： A method of and apparatus for producing a grinding tool which includes a several grinding sheets radially arranged on a disk. The disk, having a hole in its center and adhesive along a circumferential edge portion of its upper surface, is provided on a receiving seat. A plurality of grinding belts distributed about the periphery of the receiving seat are directed radially inward toward the center of the disk so as to cover the adhesive and such that adjacent side edges of forward ends of the belts overlap each other, each of the overlapping belt ends having a grinding particle surface on a same side thereof facing away from the adhesive. A pressing plate is directed downward against the respective belt ends on the adhesive layer to adhere the respective belt ends to the disk. A cutting tool having a circumferential cutting edge is provided below and somewhat radially outward of the circumferentially edge of the disk. When the pressing plate is lowered, the cutting edge cuts the belts along a circular line which is coaxial with the disk. The pressing plate is held against the belt ends while the adhesive solidifies. The pressing plate is then raised so that the completed grinding tool can be removed from the receiving seat. The adhesive may or may not be heat sensitive. If the adhesive is heat sensitive, heating elements are provided in the pressing member and the receiving seat to melt the adhesive.

摘要： A support disc preferably has an annular periphery, a central opening and a pair of substantially parallel side surfaces. Abrasive packs are disposed on the periphery of the disc in spaced relationship to one another. Each pack is formed from a stack of thin abrasive strips having abrasive particles on one surface. The packs are attached to the disc periphery with opposite ends disposed against the opposite side surfaces of the disc. The packs are preferably tilted in the direction of disc rotation so that the trailing edge of the outermost strip in each pack engages the workpiece. When the angle of tilting is large, the pack ends of the packs may be cut at an angle to facilitate an abutting relationship between adjacent disc packs. In one embodiment, the abrasive wheel is disposable. In another embodiment, only the abrasive packs on the disc (and not the disc) are disposable. In this embodiment, the packs may be bent into a horse-shoe shape and bonded to one another at their peripheries as by resin. In both embodiments, the disc and the peripherally disposed packs can be supported for rotation as by a pair of plates with center holes, each disposed against the packs at an opposite side surface of the disc. A motor arbor can be extended through the center holes of the plates and the disc. A nut attached to the arbor can retain the plates in pressed relationship against the packs on the disc for rotation of the packs against a workpiece.
摘要翻译：支撑盘优选地具有环形周边，中心开口和一对基本上平行的侧表面。研磨剂组件以彼此间隔开的关系设置在圆盘的周边上。每个包装由一堆在一个表面上具有磨料颗粒的细磨料条形成。这些包装件被附接到盘周边，相对的端部抵靠盘的相对侧表面设置。这些包装件优选地在盘旋转的方向上倾斜，使得每个包装件中最外面的条带的后缘接合工件。当倾斜角度大时，可以以一定角度切割包装的包装端部，以便于相邻的盘包装件之间的邻接关系。在一个实施例中，砂轮是一次性的。在另一个实施例中，只有盘（而不是盘）上的磨料包是一次性的。在该实施例中，包装可以弯曲成马鞋形状，并且通过树脂在它们的周边彼此粘合。在两个实施例中，盘和外围布置的包可以被支撑为旋转，如通过具有中心孔的一对板，每个板在盘的相对侧表面处抵靠包装。电动机轴可以延伸穿过板和盘的中心孔。附接到心轴的螺母可以将板压在与盘上的包装件上的压力关系上，以使包装件相对于工件旋转。
