Abstract:
A bending machine designed to bend and shape sheet metal comprises a blade-holder unit (10) with a “C” shaped cross-section, mobile along two mutually orthogonal directions with respect to a fixed bed, and on which one or more bending blades are fixed. This machine comprises a kinematic system for driving the operating units, in which servomotors (15, 21, 22) and epicyclical reduction gears are used for the movement of the blade-holder unit (10). Moreover, the blade-holder unit (10) of the bending machine uses an articulated mechanism consisting of two mechanical units (13, 14) which form a closed kinematic chain with five members connected by five kinematic turning pairs.
Abstract:
A method for the production of mirrors (4) comprising a preliminary controlled pre-deformation treatment of an optical system (1) consisting of the following phases of: calculation of the deformation of the optical system (1) due to a selected reflecting treatment (2); design of a deforming layer (3) such as to produce on the optical system (1) a deformation opposite to the one caused by the selected reflecting treatment (2); and deposition on the optical system (1) of a deforming layer (3), on which the selected reflecting treatment (2) will subsequently be deposited.
