MIXER MODULE FOR A DETERMINISTIC HYDRODYNAMIC TOOL FOR THE PULSED POLISHING OF OPTICAL SURFACES, AND PULSED POLISHING METHOD.

摘要

The present invention relates to a hydrodynamically optimised mixer module to be coupled to a deterministic hydrodynamic tool for the pulsed polishing of optical surfaces, which is configured such that the supply of abrasive foam or fluid can be interrupted without impairing the operational stability of the polishing process and of the hydrodynamic tool. The mixer module comprises: at least one interrupter element for interrupting high-speed fluids, which may be disposed inside or outside the body of the mixer module for the purpose of interrupting the controlled-pressure and -flow supply of the abrasive foam; a first inlet through which air is injected under pressure and in a controlled manner; a second inlet through which a polishing fluid is injected in a controlled manner, said polishing fluid filling a previously calculated space with an optimised hydrodynamic shape and being transferred to a mixing zone where, together with the pressure-injected air, the abrasive foam is produce d that is injected into a module of at least one rotational acceleration chamber of the hydrodynamic tool. The invention also relates to a method for carrying out the deterministic polishing process.
