The feed mechanism includes a feed frame, a sliding platform, a sliding drive member, multiple columns of storage mechanisms for storing polishing pads, and multiple columns of push mechanisms, and the number of the columns of the storage mechanisms matches the number of the columns of the push mechanisms. The feed frame is mounted on the machine frame. The sliding platform is slidably arranged on the feed frame. The storage mechanisms are mounted on the sliding platform. The push mechanisms are mounted on the feed frame and are located above the storage mechanisms.

A method and associated system provides automated abrasive paint repair using automated abrasive paint repair devices that selectively sand, buff, and polish a substrate in response to received instructions generated by a controller. The controller receives coordinates of each identified defect in the substrate along with parameters describing characteristics of each defect, selects a sanding process, a buffing process, and/or a polishing process based on empirically derived rules established by skilled/expert human operators and the received parameters. The controller outputs instructions to cause the automated abrasive paint repair devices to execute the selected sanding process, buffing process, and/or polishing process using the received parameters. The empirically derived rules and parameters may be stored in a lookup table and/or updated by a machine learning module.

There is provided a substrate processing device. This substrate processing device includes a substrate holder that holds and rotates a substrate, a first processing head that processes a first plane of the substrate held on the substrate holder, and a second processing head that processes a peripheral portion of the substrate held on the substrate holder.

A tire grinding machine includes a frame having a plurality of vertically extending posts. A chuck assembly is associated with the frame and adapted to receive and rotate a tire. A grinding assembly is associated with the frame and is movable with respect to the frame. The grinding assembly has at least one grinding element adapted to contact and remove material from the tire when rotated by the chuck assembly. A counterbalance assembly which has a cable with one end connected to a counterbalance weight and an opposite end connected to the grinding assembly is included. A block assembly may be coupled to the grinding assembly to allow pivotable movement thereof. A calibration adapter may be used to ensure proper positioning of the grinding elements, wherein a level adjuster may be used for this purpose.

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.

A workpiece grinding method includes a groove formation step, a groove removal step, and a full surface grinding step. In the groove formation step, the workpiece is ground by performing grinding feed of a grinding unit while rotating a spindle without rotation of a chuck table, so that an arcuate groove is formed with a depth not reaching a finish thickness on a side of a back surface of the workpiece. In the groove removal step, rotation of the chuck table is started with the spindle kept rotating, so that the groove is ground at side walls thereof and is removed from the workpiece. In the full surface grinding step, grinding feed of the grinding unit is performed while the spindle and chuck table are rotated, so that the workpiece is ground in an entirety thereof on the side of the back surface until the workpiece has the finish thickness.

The present invention relates to a device (14) for sanding floor areas, the device comprising a frame, a steering, a motor which is provided to said frame, a subframe (13) rotatably coupled with said motor, said subframe being centrally provided with an adapter (7) along the lower side, a sanding frame (1), said sanding frame being centrally provided with a receiver (2) along the upper side, said receiver receiving said adapter, and at least one holder (5) for sanding elements, said holder being provided along the lower side of said sanding frame and being suitable for the attachment of sanding elements (15). In particular, the subframe is freely supported by the sanding frame, via said adapter and receiver, said adapter and receiver being rotationally coupled. In other aspects, the invention relates to a sanding frame, a sanding element and a method for sanding floor areas, as well as a floor area obtained by application of said method.

Disclosed is a device for automatically removing burrs from a riser of an aluminum alloy wheel. The device is composed of a frame, a clamping gear rack structure, a support plate, a servo motor and the like. When a clamping cylinder drives a first sliding plate to move, clamping wheels are controlled to center and clamp the wheel, and the servo motor controls the rotation of the clamping wheels, so that the wheel may rotate while being clamped. When a distance adjusting cylinder drives a second sliding block to move, a first sliding block and the second sliding block move synchronously under the action of a feed gear rack structure, so that a first deburring tool and a second deburring tool move synchronously to adjust the distance between them according to the diameter of a cap slot.

A method for producing a rolling sharpener having at least one grinding or polishing face for grinding and/or polishing a cutting tool, the rolling grinder being formed substantially from two rollers, a grip body to be arranged between the rollers and rotatably relative thereto, and a shaft to be supported rotatably in the grip body. To make correct operation of the rolling grinder user-friendly and to facilitate correct operation overall, each of the rollers is connected to the shaft in a frictionally engaged manner.
