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.

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： There are provided: a linear motion guide device, which enhances workability of raceway surfaces and is capable of reducing production cost; and a production method for the linear motion guide device. For this purpose, a linear motion guide device includes a guide rail (1), a slider (2), and a plurality of rolling elements (4), and the guide rail (1) and the slider (2) individually have raceway surfaces (11, 21), which form a rolling path (3) of the rolling elements (4), at positions opposite to each other. Then, the rolling elements (4) are disposed in the rolling path (3), and the slider (2) moves with respect to the guide rail (1) via the rolling elements (4). The raceway surface (21) of at least one of the slider (2) and the guide rail (1) is composed of: a first raceway surface (21A); and second raceway surfaces (21B) extending on both sides of the first raceway surface (21), and surface roughness of the second raceway surfaces (21B) is set rougher than surface roughness of the first raceway surface (21A).

摘要： Disclosed is a grinding tool (1) for highly accurate centre-less grinding in continuous process for shaft-like workpieces (16), comprising at least one conical (3) and one cylindrical grinding region (4). With its first grinding cover (13), the conical grinding region (3) is primarily intended for grinding larger cutting volumes, whereas the cylindrical grinding region (4), with its second grinding cover (14) is primarily intended for achieving the highest surface quality, without, in the case of the latter, having to remove large cutting volumes. The grinding covers (13, 14) differ at least in respect of the grinding agent used, CBN preferably being used in the conical region and diamond being used in the cylindrical region. Further disclosed is a method, which works with the grinding tool (1) as per the invention and which grinds the shaft-like workpieces (16). Oversize and surface quality are at least temporarily simultaneously ground.

摘要： A grinding wheel assembly for grinding and sizing workpieces such as an elastomeric power transmission belt is provided that comprises a wheel member including an abrasive, annular outer surface, a pair of annular flange members detachably connectable to opposing sides of the wheel member for providing opposing annular flanges that circumscribe and radially extend beyond opposing sides of the outer surface of the wheel member, wherein each of the flanges includes an inner abrasive surface for sizing a workpiece which is substantially coarser than the abrasive surface on the outer surface of the wheel member. Additionally, an undercut portion is provided beneath the distal end of each of the inner side surfaces of the flange members for providing a space for collecting grindings produced by the sizing operation, as well as for creating a flow of turbulent air which effectively expels the grindings from the assembly, thereby preventing them from accumulating and compacting between the inner sides of the flanges of the grinding wheel assembly and the belt or other workpiece.
