The present disclosure provides a device for repairing appearance defects and repair method. The device comprises: a moving platform and at least one repair mechanism, each the repair mechanism comprises at least one sub-repair mechanism, each the sub-repair mechanism comprises a first moving portion, a second moving portion, and a repair portion; the moving platform is configured to support an apparatus to be repaired and move in a first direction to drive the apparatus to be repaired to move in the first direction; the first moving portion is configured to move in a second direction to drive the repair portion to move in the second direction, and the second direction intersects the first direction perpendicularly; the second moving portion is configured to move in a third direction to drive the repair portion to move in the third direction.

A glass polishing device has a casing adapted for operative engagement with the exterior surface of a powered drill motor. The casing includes a handle extending from a second side opposite an opening in an opposite first side thereof from which a handle of the engaged drill motor projects. A triggerable fluid supply is coupled to the casing and projects fluid to a tool or a section of glass being resurfaced by the tool.

An electronic device may have a glass housing structures. The glass housing structures may be used to cover a display and other internal electronic device components. The glass housing structure may have multiple glass pieces that are joined using a glass fusing process. A peripheral glass member may be fused along the edge of a planar glass member to enhance the thickness of the edge. A rounded edge feature may be formed by machining the thickened edge. Raised fused glass features may surround openings in the planar glass member. Multiple planar glass members may be fused together to form a five-sided box in which electronic components may be mounted. Raised support structure ribs may be formed by fusing glass structures to a planar glass member. Opaque masking material and colored glass may be used to create portions of the glass housing structures that hide internal device components from view.

A substrate polishing apparatus including a stage configured to load a substrate, the stage having a flat surface, which is parallel to a first direction and a second direction, and on which the substrate is loaded, a pressing unit configured to exert a pressure on the substrate in a third direction, a rotary unit configured to revolve the pressing unit around a central axis parallel to the third direction, when viewed in a plan view, a plurality of polishing pads provided between the pressing unit and the substrate to be in contact with the substrate, and a nozzle part configured to supply a slurry onto the substrate. The polishing pads may be spaced apart from each other in a direction and may have a rectangular shape in the plan view.

A method for producing a heat-resistant roll, and a roll produced by the method, the method including: fabricating a roll part comprising 5 wt % or more of a clay mineral; grinding the roll surface of the roll part; conducting a surface treatment in which the ground roll surface is smoothed in a moisturized state; and forming a coating film of a clay mineral on the surface-treated roll surface.

A method of forming a recess in a surface of a substrate includes: providing an abrasive article comprising a structured abrasive member disposed along a peripheral surface of a support member, frictionally contacting the structured abrasive layer with a surface of a substrate, longitudinally advancing the structured abrasive layer relative to the surface of the substrate; and rotating at least one of the abrasive article or the substrate relative to the other around a rotational axis perpendicular to the surface of the substrate such that the structured abrasive layer maintains contact with and abrades the surface of the substrate. The structured abrasive member comprises a structured abrasive layer comprising shaped abrasive composites secured to a backing, wherein the backing is proximate to the support member. The shaped abrasive composites comprise abrasive particles retained in a binder material. The present disclosure also provides an abrasive wheel comprises a structured abrasive member disposed on a peripheral surface of a support wheel and display covers including a spherically concave recess abutting a cylindrical passage.

A process for making anti-reflective optical glass comprises the steps of: A. implementing an abrading tool including a carrier having a plurality of diamond cutting wires formed on the carrier; and B. centrifugally and resiliently abrading a substrate of optical glass by the abrading tool to form a plurality of microscopic protuberances or moth-eye like structures on the substrate to thereby reduce the light reflection from the substrate and increase the light transmission in the substrate.
