摘要:
In a work polishing apparatus, a polishing head including a head base portion, in an upper portion, to which a vertically movable and rotatable head shaft is fixed, and a holding member, in a lower portion, having a lower surface on which a work is held, is provided with, on the upper surface side of the holding member, a vertically movable partitioning portion and first and second fluid chambers respectively on the inner and outer circumference sides of the partitioning portion. Pressure in the first fluid chamber and in the second fluid chamber can be independently increased or decreased. The partitioning portion can be lowered at least to a position where the first fluid chamber and the second fluid chamber are partitioned such that a pressure difference can be produced between the interior of the first fluid chamber and the interior of the second fluid chamber.

An automatic vehicle body sanding system operated in a painting factory includes a painting inspection device configured to detect a defective position (NG Point) by analyzing a 2D image of a vehicle body for which an intermediate process has been completed taken with a camera, and display the defective position on a 3D vehicle body drawing. The automatic vehicle body sanding system includes a robot having a multi-joint structure on which at least one of a 3D scanner, a sanding tool, and a dust absorber required for sanding work is mounted. Further, the automatic vehicle body sanding system includes a server configured to match the defective position of the vehicle body detected by the painting inspection device and 3D scan data of the vehicle body scanned by the 3D scanner with a 3D vehicle body drawing shape on a simulator.

A machining machine comprises a first support disk, a first working disk coupled to the first support disk, and a counter bearing element positioned to define a working gap between the first working disk and the counter bearing element. The first working disk and the counter bearing element are configured to rotate relative to each other to machine at least one side of a flat workpiece. A pressure volume is positioned between the first support disk and the first working disk and is configured to hold a pressure fluid, which generates a pressure configured to deform the first working disk. One or more temperature-controlling channels are positioned within the first working disk and configured to hold a temperature-controlling fluid that is configured to control a temperature of the first working disk, wherein the one or more temperature-controlling channels are fluidly separate from the pressure volume.

A material removal device for removing material from a substrate includes a holder extending between first and second sides and a grinding wheel supported by the holder and being operable to remove the material from the substrate. The holder has a guide frame at the first side and a support frame at the second side. The guide frame has a first bottom surface and the support frame has a second bottom surface. The first and second bottom surfaces are vertically offset from each other. The grinding wheel has an axle supported by the guide frame and the support frame. The grinding wheel has a grinding surface located below the first bottom surface and above the second bottom surface.

A flush cut grinder tool bit made of an elongated cylindrical shape with an inwardly facing saw blade within the inner diameter of the elongated cylindrical shape that can be sleeved over a protruding object, such that the cutting saw blade portion of the tool bit is inside the cylindrical tool bit so that when it is sleeved over a protruding object, moving the tool bit back and forth over the protruding object will cut the protruding object off at the surface. The body of the drill bit terminates at its distal end with a flush flange having saw teeth therein, and may include a bit shank suspended in the middle of a drill bit body by spokes or a solid surface radially extending from said bit shank. A method of using such a flush cut grinder tool bit is included.

The present invention relates to a hammer union restoration apparatus wherein a main sanding unit is mounted to a base. The main sanding unit including a sander for sanding the four side faces of a lug formed on the hammer union. The sander being resiliently movable in a direction away from a side face of the lug. The sander is movable under control of a motor to rotate the sander relative to the lug around the four faces of the lug with the sander floating across the corner edges of the four faces. The present invention further includes a sander for sanding the end face of the lug.

A first angular grinding wheel and a straight grinding wheel having rotation axes parallel to each other are arranged on a swivel slide that turns about a turning axis. A reference symmetry plane (MA) that is parallel to a grinding wheel rotation axis and that includes the turning axis and a reference perpendicular plane (MB) that is perpendicular to the reference symmetry plane and that includes the turning axis are defined. A grinding reference point (PA1) of the first angular grinding wheel (TA1) and a grinding reference point (PP1) of the straight grinding wheel (TP1) are arranged asymmetrical with respect to the reference symmetry plane. A distance from the grinding reference point of the straight grinding wheel to the reference symmetry plane is equal to a distance from the grinding reference point of the first angular grinding wheel to the turning axis.
