摘要： The invention relates to a method for centering grinding of workpieces, for example optical lenses by a grinding tool using an actuator for generating an advancing movement between the grinding tool and the workpiece, wherein the actuator and a current regulator for an actuator current which determines an advancing force of the actuator are integrated in a position control loop using a predetermined control cycle. For each control cycle: (i) a desired direction of movement (Rsoll(n)) of the advancing movement and an actual direction of movement (Rist(n)) of the advancing movement are ascertained; then (ii) the ascertained actual and desired directions of movement are compared to one another; and (iii) when the comparison results in a deviation between the actual and desired directions of movement, a predetermined current limit (Isollmax) for the actuator current emitted via the current regulator is decreased in a defined manner.

摘要： A device is disclosed for the surface machining of, among other things, plastic spectacle lenses, which has a work spindle, by means of which the spectacle lens can be driven with a controlled angle of rotation about an axis of work rotation, and a tool spindle, by means of which a tool can be driven to rotate about an axis of tool rotation, work and tool spindle being movable relative to one another with their positions controlled in two axes running at right angles. For rotational machining of the surface of the spectacle lens to be machined, the tool can also be swiveled by means of the tool spindle with a controlled angle of rotation about the axis of tool rotation, so that a rotational cutting edge provided on the tool can be brought into a defined rotational machining engagement with the surface of the spectacle lens to be machined as a function of the angle of rotation of the spectacle lens. Also included is a combined milling and rotational machining tool and a combined milling and rotational machining method. As a result, high cutting rates and very good surface qualities can be easily and efficiently achieved in the surface machining.

摘要： A method for creation of a surface from a rough blank for spectacles is which is suitable for both brittle-hard materials and for plastics uses makes use of a disk-shaped, rotation-symmetrical tool of relatively large diameter, by means of which the material to be taken off the rough blank is removed with high grinding or milling efficiency in at least two work steps--a plunge-cut step and a shaping step with material removed along a spiral path. The outcome of the last work step is a machining path traveling in a spiral from the outside to the inside with low residual apex height and relatively large apex spacing. The resulting surface needs only slight fine-grinding and polishing aftertreatment. As an option, both a rim machining step adapted to the form of the eyeglass frame and a work step faceting the rim of the eyeglasses can be integrated into the method. Furthermore, tools are proposed for carrying out the grinding and milling process.

摘要： A grinding and polishing machine, in particular for lenses, has at least one tool spindle and at least one workpiece. The tool spindle is constructed to hold a respective tool on the same axis at both ends and is mounted in a spindle housing which can be pivoted about a pivot axis arranged at right angles to the tool spindle in order to provide in each case one tool for machining engagement and also at various defined angle positions with respect to the workpiece spindle. A drive arranged on the pivot axis pivotably moves the tool spindle about the pivot axis for the desired machining engagement and rotates the tool about the pivot axis into the various angle positions with respect to the workpiece.

摘要： A very versatile device is proposed for high-precision machining of optical workpieces, in particular optical lenses, which comprises a horizontally displaceable gantry with at least one vertically displaceable tool spindle and a yoke with workpiece holding means mounted so as to be rotatable about a swivel axis by means of journals fitted on both sides. For swivelling of the yoke without gearing and therefore without backlash, a torque motor is provided concentrically to the swivel axis, which motor is directly connected actively with one of the journals.
