Problems solved by technology

[0010] In this respect, however, a problem was found that the contrast between the tool surface and the barcode detectable by the camera was very small, since the polishing tool is saturated or wetted by the polishing medium during its use
On the one hand, this can lead to the result that faulty or worn tools cannot be reliably identified and thus continue to be used for polishing spectacle lenses
Polishing tools, on the other hand, have the potential to be replaced prematurely because they have been "classified" as faulty, despite the fact that they are still undamaged or unworn and therefore still usable

Embodiment Construction

[0051] exist Figure 1 to Figure 4 In , an apparatus for machining optical workpieces, in particular spectacle lenses, is denoted by the reference numeral 10 . The device 10 can be mounted as a polishing unit optionally together with other devices of the same design in a common frame (not shown) of a polishing machine, as already mentioned in the introduction DE 10 2014 015 053 A1 ( figure 1 ) is known. The device 10 generally has a working chamber 11, in particular according to Figure 2 to Figure 4 , in the working chamber 11, on the one hand a workpiece mount 12 and on the other hand at least one tool mount (in this embodiment two tool mounts 13, 13') face each other. As will be described in more detail, the workpiece mount 12 and the tool mounts 13, 13' are movable relative to each other so that, alternatively, the processing area 14 of the polishing tool 15 or the processing area 14' of the other polishing tool 15' can is in machining engagement with a workpiece (not s...

Abstract

A device (10) for processing spectacle lenses has a work chamber (11), which is accessible from the outside via an optionally closable opening (16) and in which a workpiece mount (12) and at least onetool mount (13, 13') are opposite to one another and movable relative to one another so that a processing region (14, 14') of a tool (15, 15') held at the tool mount can be brought into processing engagement with a workpiece held at the workpiece mount and in processing engagement can be guided over the workpiece. For recognition of wear at the tool, a sensor equipment (17) with at least one contactlessly operating sensor arrangement (18, 18') is provided and is movable outside the work chamber between a protected rest position and a detecting position. In the detecting position of the sensorarrangement, the sensor equipment is constructed to detect at the processing region of the tool held at the tool mount an unacceptable deviation beyond a predetermined amount from a desired geometry.

Description

technical field [0001] The invention generally relates to a device for machining optical workpieces. In particular, the present invention relates to a device for the precision machining of the optically active surface of spectacle lenses, which is widely used in so-called "RX workshops", i.e. production plants for the production of unique spectacle lenses according to prescriptions, or for the production of Regular spectacle lenses, such as those in sunglasses. Background technique [0002] The processing of the optically effective surface of spectacle lenses by material removal can be roughly divided into two processing stages, specifically, firstly, the optically effective surface is preliminarily processed according to the prescription to generate a macroscopic geometry, and then the optically effective surface is precisely processed to Eliminate preliminary machining trajectories and obtain desired micro-geometry. Although the preliminary processing of the optically ef...
