The disclosed solution comprises a device for changing abrading products (30), the device (1) comprising a detacher (2) comprising a table (10), a blade (14) adapted to penetrate into between an abrading product (30) and the gripping means (34) of the abrading tool (4), and means (16, 18, 19) to co-planarly adjust the mutual distance (d) between the table (10) and the blade (14) to correspond to the thickness (t) of the abrading product (30) in the absence of the abrading product (30).

The invention relates to a grinding machine, which is suitable for a robot-supported grinding process. According to one embodiment, the grinding machine has a housing, a motor arranged in the interior of the housing, a fan wheel arranged on a motor shaft of the motor in the interior of the housing, and a support plate coupled to the motor shaft for receiving a grinding disc. The support plate has openings for intake of grinding dust into the interior of the housing. The grinding machine furthermore has an outlet arranged in a wall of the housing for exhausting the grinding dust out of the interior of the housing and a non-rerun valve arranged in the wall of the housing. The non-return valve enables an to escape from the interior of the housing, but prevents intake of air into the interior of the housing.

A robotic device that can include an end effector configured to manipulate one or more tools that drives one or more consumable abrasive products to abrade a substrate along several different surface dimensions, wherein the end effector comprises: three linear actuators each configured to move orthogonal relative to one another and at least one tool mount coupled to one of the three linear actuators and coupled to the tool.

A mechanism for polishing includes a polishing member, an eccentric member coupled to the polishing member, and a driving member coupled to the eccentric member. The driving member drives the eccentric member to rotate to move the polishing member to reciprocate in the one-dimensional direction, so that when a relative position between the polishing mechanism and the workpiece is fixed, the polishing member polishes a workpiece by translating a polishing surface. A method for the polishing process, applied by a polishing device, is also disclosed. By using the polishing mechanism, the entirety of the polishable surface of the workpiece can be covered, and collapsed edges of the workpiece are avoided.

Automated systems and methods of using a smart end-effector tool to prepare (e.g., scuffing, abrading, sanding, polishing, etc.) an object surface are provided. The smart tool can update its working state with a robot arm in real time, which in turn adjusts locomotion parameters to optimize the tool's working state on the object surface.

Described is an apparatus for robot-aided grinding, comprising the following: a manipulator, a linear actuator, and a grinding machine which includes a rotating grinding tool and is connected to the manipulator via the linear actuator. The apparatus further comprises a protective cover that partially surrounds the rotating grinding tool, the rotating grinding tool protruding from the protective cover at least on a first side. An adjusting mechanism is provided which connects the protective cover to the grinding machine and is designed to adjust the position of the protective cover in relation to the grinding machine.

A grinding robot for grinding an electrically conducting workpiece. The grinding robot includes a grinding wheel, an actuation device for actuating grinding wheel, and a control system. The grinding wheel including an undulated tool receptacle which defines an axis of rotation about which the grinding wheel can rotate during grinding, and a head which is rotationally symmetrical with respect to the axis of rotation, and which contains abrasive material and has a grinding surface which is in contact with workpiece during grinding. The grinding wheel also includes a measuring and transmission unit and at least one conductor strand pair with two conductor strands which are electrically insulated from one another. The conductor strands are embedded in the rotationally symmetrical head and extend from the grinding surface of the head into the interior of the head and are electrically connected with measuring and transmission unit.

A flaw grinding system, a flaw grinding method, and a steel-product manufacturing method enable automation of the task of grinding a flaw on the surface of a workpiece having a three-dimensional shape, while also reducing the occurrence of faulty grinding such as over-grinding or under-grinding. The flaw grinding system includes a grinding apparatus, a shape measurement apparatus, a flaw detection apparatus, and a grinding-tool control apparatus. The grinding apparatus includes a grinding tool that grinds a flaw on a surface of a workpiece. The shape measurement apparatus measures a three-dimensional shape and an attitude of the workpiece. The flaw detection apparatus detects a location of the flaw on the workpiece. The grinding-tool control apparatus generates a trajectory of the grinding tool to grind the flaw. The grinding-tool control apparatus controls the grinding apparatus in a manner that causes the grinding tool to move along the trajectory.

According to one example, a CNC machine tool system may perform error compensation for improving the accuracy of the geometry (or form) of a machined workpiece to, for example, better than 2 micrometers. To do so, a first machined workpiece may be created using the CNC machine tool system. The CNC machine tool system may create the machined workpiece by jig grinding. Following the creation of the first machined workpiece, metrology of the workpiece error may then be performed on the machined workpiece. The metrology of the workpiece error may be used to create a corrected toolpath trajectory for re-machining. This corrected toolpath trajectory may then be utilized by the CNC machine tool system to machine a second machined workpiece having a geometry (or form) with an accuracy of, for example, better than 2 micrometers.

To change the direction of water flowing toward a painted surface so as to flow toward the center side of a hood, a water deflecting member is provided that extends toward the center side of the hood while extending toward the painted surface as seen in a state where automatic wet sanding is performed. Thus, water bouncing off the painted surface is less likely to scatter over a wide area of the painted surface, and sanding dust is also less likely to scatter over a wide area of the painted surface. As a result, it is possible to eliminate the need for the troublesome task of wiping off sanding dust remaining on the painted surface, and to achieve a quality finish on the painted surface.
