摘要： A universal abrasive article adapted to mount on a mounting surface of a sanding machine having a plurality of dust extraction holes that define an open area. The abrasive article includes a plurality of discrete apertures that are sized and positioned so as to expose a majority of the open area of the dust extraction holes independent of the angular orientation of the abrasive article when the abrasive article is in registration with the mounting surface. The discrete apertures may include elongated, arcuate slots that may be symmetrically positioned about a center point of the abrasive article. In one embodiment, the discrete apertures may include seven arcuate slots. These embodiments also include sufficient abrasive material to provide adequate sanding cut rate and structural integrity during use and removal.

摘要： In the grinding process, grinding fluid is supplied toward the grinding point where a workpiece is ground with a grinding wheel. At the same time, a fluid jet is ejected across the air flow above the grinding point in the rotational direction of the grinding wheel. As a result, the air layers on both lateral sides of the grinding wheel are turned not to head for the grinding point above the same, whereby the grinding fluid is reliably led to the grinding point without being obstructed by the air layers following both lateral sides of the grinding wheel.

摘要： An adhesive-backed sandpaper disc is affixed to the side wall of a standard off-the-shelf circular saw blade having two opposed flat planar faces devoid of any recesses and surrounded by a periphery of cutting teeth. The disc is made in a generally circular shape with an abrasive affixed on one surface and a layer of adhesive provided on an opposite surface covered with a release paper to prevent contamination before use. The sandpaper disc includes a plurality of slots extending toward or to the periphery of the disc which combine with the surface of the saw blade to create recesses that permit channeling of saw dust created during cutting and sanding operations. In an alternative embodiment, the slots can spiral in an arcuate path from adjacent the center of the disc to the periphery to enhance the ability of the slots to channel saw dust radially outwardly from the disc. A plurality of holes form cylindrical recesses in conjunction with the face of the saw blade to which the disc is affixed. These recesses permit dissipation of heat from the saw blade and also provide locations where saw dust can be retained so that it does not interfere with cutting and sanding operations. The disc not only sands the sides created during cutting operations but also dampens vibrations, balances the saw blade, and reduces noise. A method of using the disc is also disclosed.

摘要翻译： 粘合剂背面的砂纸盘固定到标准现成的圆锯片的侧壁上，该圆形锯片具有两个相对的平坦的平面，没有任何凹槽并被切割齿的周边包围。 盘被制成大致圆形形状，附着在一个表面上的磨料和一层粘合剂，其设置在用隔离纸覆盖的相对表面上，以防止在使用前被污染。 砂纸盘包括朝向或朝向盘的周边延伸的多个槽，其与锯片的表面组合以产生允许在切割和砂磨操作期间产生的锯屑的通道的凹槽。 在替代实施例中，槽可以从邻近盘的中心到周边的弧形路径螺旋形，以增强槽从盘径向向外引导锯屑的能力。 多个孔与盘片固定在其上的锯片的表面一起形成圆柱形凹槽。 这些凹槽允许从锯片散热并且还提供可以保持锯屑的位置，使得其不干扰切割和打磨操作。 光盘不仅会在切割过程中产生的边缘磨砂，而且还会抑制振动，平衡锯片，并降低噪音。 还公开了使用该盘的方法。

摘要： A method and apparatus for releasably attaching a planarizing medium, such as a polishing pad, to the platen of a chemical-mechanical planarization machine. In one embodiment, the apparatus can include several apertures in the upper surface of the platen that are coupled to a vacuum source. When a vacuum is drawn through the apertures in the platen, the polishing pad is drawn tightly against the platen and may therefore be less likely to wrinkle when a semiconductor substrate is engaged with the polishing pad during planarization. When the vacuum is released, the polishing pad can be easily separated from the platen. The apparatus can further include a liquid trap to separate liquid from the fluid drawn by the vacuum source through the apertures, and can also include a releasable stop to prevent the polishing pad from separating from the platen should the vacuum source be deactivated while the platen is in motion. In another embodiment, a signal can be applied to the platen to draw the polishing pad toward the platen via electrostatic or electromagnetic forces. In still another embodiment, the polishing pad can be attached to a pad support and conditioned on a separate jig.
