It also relates to a cleaning kit including an application device and a cleaning solution, and to a method for cleaning grinding surfaces.

A device and a method for processing, in particular edge processing, an optical lens, wherein the device has a measuring system, a processing system, a loading system, an unloading system, an intermediate conveyor, and a belt conveyor. The loading system is arranged between the measuring system and the processing system. The unloading system is arranged on the opposite side of the processing system. A lens that is to be processed is picked up and oriented at the optical reference point that is determined by the measuring system in order to determine as precisely as possible the blocking point for the subsequent processing. The loading system and unloading system each have a linearly movable swiveling system with linearly movable suction devices arranged therein. The processing system is designed for the simultaneous processing of two lenses.

A cooling lubricant supply device for supply of a cooling lubricant to a grinding wheel is rotatably mounted as a tool on a grinding spindle of a processing unit in a grinding machine. The device has a feed shoe, which is mounted at least indirectly on a grinding spindle housing and seated on a circumferential surface of the grinding wheel and which has a seating surface facing the grinding wheel. The seating surface has a shape substantially complementary with the circumferential surface of the grinding wheel and is provided centrally with a pocket-like recess into which the cooling lubricant can be fed under pressure. A spring mechanism is provided, by which the feed shoe is biased with the seating surface thereof against the circumferential surface of the grinding wheel.

The invention discloses a processing apparatus for elliptical annular optical glass, including a processing box, wherein the processing box is provided with a processing chamber with an opening forward, a sliding block is slidably mounted in the processing chamber, and the second motor passes through the power rod The disc is driven to rotate forward, and the disc drives the scriber to rotate through the connecting block. After the scribing mechanism completes the scribing of the glass, the sliding block moves downward through the first motor, and the sliding block moves downward to remove the excess glass. No manual operation is required, and the manual operation of the broken glass is avoided. The polishing block in the polishing mechanism polishes the glass to ensure that the glass is not scratched when the glass is manually removed, and is slid when the glass is large.

A device for fine processing of optically effective surfaces on workpieces has a workpiece spindle which protrudes into a working space and by which a workpiece to be polished can be rotationally driven about a workpiece axis of rotation. Two tool spindles are associated with the workpiece spindle and protrude into the working space oppositely to the workpiece spindle. On each tool spindle, a polishing tool can be rotationally driven about a tool axis of rotation and is retained so that the polishing tool can be axially advanced along the tool axis of rotation. Furthermore, the tool spindles can be moved together in relation to the workpiece spindle along a linear axis extending substantially perpendicularly to the workpiece axis of rotation and can be pivoted about different pivoting adjustment axes, which extend substantially perpendicularly to the workpiece axis of rotation and substantially perpendicularly to the linear axis.

Disclosed is an apparatus for processing a lens edge. The apparatus comprises: a wheel-shaft-moving rotating member whose one end is fixed to a fixing frame by a moving-shaft, for moving pivotally about the moving-shaft; a wheel-shaft mounted on the other end of the wheel-shaft-moving rotating member, for moving pivotally with the wheel-shaft-moving rotating member and for being rotated by driving a wheel-rotating motor; and a cutter for processing the lens edge into a form of a step/incline shape, the cutter being coupled to one end of the wheel shaft to move with the wheel-shaft to contact the lens edge, and rotated with the wheel shaft to cut the surface of the lens, and the cutter comprising a rotating body inserted into the wheel-shaft to rotate with the wheel-shaft, and at least one cutting projection formed on the circumference of the rotating body to cut the edge and the periphery of the lens.

An opaque adhesive can be used to secure the convex surface of a lens blank to a lens blocking piece. This opaque adhesive can include a resin that is curable under ultraviolet light and contains many dispersed pigment particles. The pigment particles may absorb light in the wavelength range of about 300 nm to about 800 nm such that the adhesive appears substantially opaque. A lens-on-block (LOB) system that uses the opaque adhesive to adhere a lens blank to a lens blocking piece facilitates on-block inspection of surface defects by increasing the contrast of light reflected from the surface being inspected. Put differently, the defects in the lens blank's surfaces stand out more when viewed in front of the opaque adhesive The inspection results can be used to carry out rework loops that eliminate or correct the detected defects, providing a streamlined method for on-block manufacturing of ophthalmic lenses.
