摘要： The present disclosure provides improved rail grinding tools. Precision-shaped grains (PSGs), such as PSGs manufactured by 3M® company, provide significant performance improvement in resin-bond and vitrified bond grinding wheels. The use of PSG improves the performance of portable bonded wheels and precision grinding wheels, such as resin bond roll grinding wheels, flute grinding wheels, vitrified gear grinding wheels, cylindrical grinding wheels, and surface grinding wheels. The formation and composition of (e.g., monolithic) and multiple-layer PSG grinding tools described herein provides improved performance of rail grinding tools.

摘要： A polishing or grinding pad with a multilayer reinforcement is provided. In one aspect, a floor polishing or grinding pad assembly employs a flexible pad, at least two reinforcement layers or rings with different characteristics, and multiple floor-contacting tools such as abrasive disks. In another aspect, a workpiece polishing or grinding pad assembly includes a flexible and rotatable pad, a polymeric reinforcement layer coupled to the pad and a metallic reinforcement layer to which are coupled abrasive tools. In yet another aspect, a floor-facing reinforcement is more flexible than a pad-facing reinforcement which is more rigid.

摘要： The present disclosure relates to a tool for sanding and buffing an irregularly shaped surface that includes a head having a rounded surface, a first abrasive material adapted for sanding or buffing, the first abrasive material attached to the rounded surface via an adhesive substance or other attaching means and at least partially covering the rounded surface, and a handle attached to the head. The tool may further include a second abrasive material attached to the rounded surface via the adhesive substance or other attaching means that at least partially covers a portion of the rounded surface not covered by the first abrasive material. If the first and second abrasive materials have varying properties such as their coarseness, the user may find each material to be especially efficient for use in separate sanding, buffing, or polishing processes.

摘要： The present application relates to polishing pads for chemical mechanical planarization (CMP) of substrates, and methods of fabrication and use thereof. The pads described in this invention are customized to polishing specifications where specifications include (but not limited to) to the material being polished, chip design and architecture, chip density and pattern density, equipment platform and type of slurry used. These pads can be designed with a specialized polymeric nano-structure with a long or short range order which allows for molecular level tuning achieving superior themo-mechanical characteristics. More particularly, the pads can be designed and fabricated so that there is both uniform and nonuniform spatial distribution of chemical and physical properties within the pads. In addition, these pads can be designed to tune the coefficient of friction by surface engineering, through the addition of solid lubricants, and creating low shear integral pads having multiple layers of polymeric material which form an interface parallel to the polishing surface. The pads can also have controlled porosity, embedded abrasive, novel grooves on the polishing surface, for slurry transport, which are produced in situ, and a transparent region for endpoint detection.

摘要： A blade sharpening system for log saw machines is provided. An example multiphase grinding wheel has a grinding face with one or more abrasive concentric rings for sharpening the cutting blade of the log saw machine, and one or more padded concentric rings consisting of fiber padding. Sharpening with the multiphase grinding wheel improves cut quality, increases blade life, removes glues and varnishes from the cutting blade, reduces blade deformation, and hones the edge of the cutting blade. A pneumatic tensioning system uses air bladders to apply a dynamically cushioned pressure between the grinding wheels and the cutting blade. The fiber-padded grinding wheels and the air bladder tensioner provide improved sharpness of the cutting blade and longer life for the mechanical components. The padded grinding wheels decrease fire risk, and the tensioner can be operated remotely, decreasing human injuries common with conventional setup actions near the sharp cutting blade.
摘要翻译： 提供了锯木机的刀片磨边系统。 示例性多相砂轮具有带有一个或多个研磨同心圆的研磨面，用于磨削原木锯床的切割刀片以及由纤维填料组成的一个或多个填充的同心圆。 用多相砂轮磨削可提高切割质量，增加刀片寿命，从切割刀片上清除胶水和清漆，减少刀片变形，并磨平刀片边缘。 气动张紧系统使用空气囊在砂轮和切割刀片之间施加动态缓冲的压力。 纤维填充砂轮和气囊张紧器提供了改进的切割刀片的清晰度和更长的机械部件的使用寿命。 填充的砂轮减少了火灾风险，张紧器可以远程操作，减少锋利的切割刀片附近的常规设置动作常见的人身伤害。
