A grinding machine for grinding a surface of an object is described which has a plurality of grinding brushes which are rotatably mounted about a brush axis of rotation, at least one brush carrier on which at least one of the grinding brushes is mounted and which is rotatably mounted about a carrier axis of rotation, and a conveying device for conveying the object at a feed speed through the grinding machine. The grinding machine has an input device and an output device. A brush rotational speed about the brush axis of rotation and/or a carrier rotational speed about the carrier axis of rotation and/or the feed speed is/are adjustable by the input device, and an expected grinding result can be output by the output device.

Disclosed is a semi-manual machine tool for treating flat horizontal surfaces, this machine including: a base; a drive plate connected to the base having a lower face adapted to be connected to a working tool; a motor; a transmission system between the motor and the drive plate; a handle for controlling the machine; and a working tool connected to the lower face of the drive plate. The drive plate is connected to the base in a manner sliding along a direction parallel to the direction of translation of the machine tool, i.e., parallel to the longitudinal axis of the machine tool, the transmission system being configured to impart to the drive plate a reciprocating rectilinear movement along the longitudinal direction.

A system for magnetic abrasive finishing of a workpiece may include a magnetic abrasive brush that may include a plurality of magnetic/abrasive particles and an electromagnet configured to apply a magnetic field on the plurality of magnetic abrasive particles. The system may further include a first actuating mechanism that may be configured to actuate a rotational movement of the workpiece about a longitudinal axis of the workpiece, a second actuating mechanism that may be configured to actuate a linear movement of the magnetic abrasive brush along a first direction relative to the workpiece, the first direction parallel to the longitudinal axis of the workpiece, a sensor coupled to the magnetic abrasive brush that may be configured to measure a working gap between the magnetic abrasive brush and an outer surface of the workpiece at any given instant. The working gap may be a distance between a center of the magnetic field and the outer surface of the workpiece along a first axis perpendicular to the longitudinal axis of the workpiece. The system may further include a control unit that may be coupled to the magnetic abrasive brush and may be configured to adjust a magnetic flux density of the magnetic field based on the measured working gap at any given instant.

A method for coordinating an identification of a defect in the surface coating of a workpiece and processing same via grinding and/or polishing using at least one grinding or polishing tool that is moveable over the defect in an automatic and computer-controlled manner based a stored program is provided. The surface coating of the workpiece is automatically optically scanned and the scanned position data is detected in a database. The defect is identified by comparing the detected position data with stored target data of the workpiece. Possible movements of the grinding or polishing tool are simulated to process the defect. The setting data for the grinding or polishing tool determined in the simulation is forwarded to a master computer. The determined processing data for processing the defect is transferred to the grinding or polishing tool. The defect is processed using the grinding or polishing tool.

Disclosed is a device for removing burrs from an aluminum alloy hub. The device includes a workbench, columns, a brush, a spindle, a spindle box, a cross beam, a spindle motor, a controller, a parallel robot, and a displacement sensor. Columns are fixedly connected to the workbench, and the cross beam is connected to the columns and a position of the cross beam can be adjusted along the columns; the spindle box is connected to the cross beam, and moves horizontally on the cross beam; the spindle, the spindle motor and the controller are mounted on the spindle box, and the brush is mounted at the end of the spindle; the brush is driven to rotate by the spindle motor and controlled by the controller; and the displacement sensor is mounted in the brush. The parallel robot can implement precise adjustment, and can perform real-time posture adjustment according to the instruction of the controller to ensure that the brush is always in close contact with the back cavity of the hub.

Methods for strengthening edges of a laminated glass article comprising a glass core layer positioned between a first glass clad layer and a second glass clad layer are disclosed. The methods may comprise polishing the cut edges of the laminated glass article with a slurry of polishing media applied to the edges of the laminated glass article with brushes. An edge strength of the laminated glass article is greater than or equal to about 400 MPa after polishing.

The floor machine provides an attachment system capable of securing a handle to the floor machine at multiple locations. A housing of the floor machine provides two attachment bodies located on the exterior of two different walls of the housing. By securing the handle to the different attachment points, the user can configure the footprint of the floor machine to increase the user's access to narrower and/or smaller confined areas.

A handheld texturing tool to apply or reapply joint compound in deficient areas of a larger textured surface so that a new texture can be rendered to the deficient areas without disturbing the larger textured surface.

A carrier head for holding a substrate in a polishing system has a housing including a carrier plate, a first flexible membrane secured to the housing, and a plurality of independently operable piezoelectric actuators secured to the carrier plate. The first flexible membrane has an upper surface and having a lower surface that provides a substrate mounting surface. The piezoelectric actuators are positioned above the first flexible membrane so as to independently adjust compressive pressure on the upper surface of the first flexible membrane.
