Abstract (en)

[origin: EP0794036A1] The polishing or grinding machine (1) moves a tool relative to the workpiece, with liquid or supercritical CO2 being supplied to the tool. The CO2 supplier includes a valve (11) for regulating the through flow rate of the CO2 with a relief jet (7). The relief jet is for the liquid and supercritical CO2. The valve is inside the machine. There may also be a valve (8) with a tube (6) which has a valve spindle (12) running through it/ The spacing between the tube and the spindle is such that liquid or supercritical CO2 is not relieved inside the tube.
