A process for improving the performance of the sliding rheostat of 5G communication high-frequency signal board with the sliding rheostat slides along between two bonding pads, includes the following steps: outer layer etching; resin plugging: a. plugging the resinous ink into the pre-plugging position; b: baking, baking on the baking plate of the oven after the plugging is finished; board polishing: using a ceramic brush to process the plugged board, then using a non-woven fabric blush to polish the surface that is polished by ceramic brush. The present invention provides a process for improving the performance of the sliding rheostat of 5G communication high-frequency signal board. The resin plugging method is used to plug the gap between the conductors of the sliding rheostat, so as to prevent the sliding rheostat from being unable to slide due to the altitude difference between conductors of the high-frequency signal board.

The application discloses a wheel burr removing device, which includes a lower brush system, a synchronous clamping and rotating system, an upper brush system and the like. The device may be used for removing burrs from a riser, an upper flange, a center hole and a flange plate edge of a wheel, and has the characteristics of high automation degree, advanced process, strong universality and high safety and stability at the same time.

The subject of the present invention is a rotationally drivable rotary tool device and in particular a rotary brush tool. The invention is equipped, in its basic construction, with a tool holder (1, 2) having at least one drive-side clamping element (1) and a tool-side clamping element (2). The two clamping elements (1, 2) are connected releasably together and receive a rotary tool (5, 6). Furthermore, the two clamping elements (1, 2) ensure that the rotary tool (5, 6) is held. According to the invention, the tool-side clamping element (2) and the rotary tool (5, 6) define a structural unit (2, 5, 6). To this end, the clamping element (2) in question is configured as a holding cage (2) that encloses the rotary tool (5, 6) radially and axially at least in part.

A device for deburring edges of a pile of metal blanks includes a first roller, a second roller, at least one motor, and a main body. The first roller is supported for rotation about a first axis. The second roller is supported for rotation about a second axis. The at least one motor is drivingly coupled to the first and second rollers to rotate the first roller in a first rotational direction and the second roller in a second rotational direction that is opposite the first rotational direction. The main body supports the first roller, the second roller, and the at least one motor. The main body is movable about a periphery of the pile of metal blanks and is configured to permit contact between the first and second rollers and the edges of the pile of metal blanks.

A tool attachment for cleaning wheel hub components, comprises a tool body having a drive end, and a cleaning end. The cleaning end comprises a lug receiving opening extending into the tool body from an axial end thereof, and an axial end face. Moreover, a brush strip is positioned in an interior surface of a chamber within the cleaning end of the tool body. In some embodiments, the brush strip is replaceable. Further, the tool attachment includes an abrasive disk having an aperture therethrough that aligns with the lug receiving opening. In this regard, the abrasive disk attaches to the axial end face of the tool body. In some embodiments, the abrasive disk is replaceable.

Disclosed in the application are a multifunctional wheel burr removing device, which includes a lower brush system, a turnover system, a synchronous clamping and rotating system, an upper brush system and the like. The multifunctional wheel burr removing device may be used for removing burrs from a riser, a cap seam allowance, a valve hole, bolt holes and bolt counter bores of a wheel, and has the characteristics of high automation degree, high removal efficiency, advanced process, strong universality, and safe and stable performance at the same time.

An edge processing device includes: conveying means that convey a molded powder compact, a first rotating tool disposed on one side and a second rotating tool disposed on the other side and rotating in a direction identical to a direction the first rotating tool rotates. The first rotating tool contacts from an upstream side with a first corner portion between one side surface of a processing target portion of the molded powder compact and a rear surface of the processing target portion. The second rotating tool contacts from a downstream side with a second corner portion between the other side surface of the processing target portion and a front surface of the processing target portion. The second rotating tool faces the first rotating tool with the conveying path therebetween, and is positionally displaced to the downstream side with respect to the first rotating tool.

A brush assembly for treating a surface of a workpiece. The assembly has a housing, a brush holder rotatable on the housing about an axis, a ring brush carried on the holder and having an annular array of radially outwardly projecting bristles. The holder and brush are rotated about the axis and reciprocated.

A brush-like grinding stone (3) in a polishing brush (1) includes a brush holder (6) and a linear member aggregate (7) detachably held in the brush holder (6). The linear member aggregate (7) includes a large number of bundles (51) of the linear members (50) obtained by hardening aggregated yarn of inorganic filaments impregnated with a resin, and a brush holder (70) holding ends of the bundles (51). A linear member holder (70) in the linear member aggregate (7) is detachably attached to each of a plurality of holding holes (68) that is open in one side in an axial line direction L. In a case where any of the linear member aggregates has a failure, such as breakage, only the failed linear member aggregate needs to be replaced. Thus, it is not necessary to discard the entire brush-like grinding stone. Consequently, the polishing cost can be reduced.
