Preformed block piece with three points of support |
| abstract |
The invention relates to a block piece (1) for holding an optical lens (2) to be machined, with a coupling part (1.1) for holding in a workpiece chuck (3) and with a holding part (1.3) for fastening the lens (2). The holding part (1.3) has a convex or concave holding surface (1.4) corresponding to a first side (2.1) of the lens (2). The holding surface (1.4) is, according to the shape of the lens (2) to be held, provided in the form of a negative free-formng surface, and the block piece (1) is made from a plastic that can be machined. |
