Method and device for the surface finishing of workpieces
10357866 · 2019-07-23 · ·

A method for the surface finishing of workpieces moves the workpiece, including rotating about at least one axis, relative to a bed of a granular grinding and/or polishing material. The workpiece is accelerated to different speeds of rotation in relation to the bed of the granular grinding/polishing material. The workpiece or a container containing the bed of granular grinding/polishing material to be accelerated in periodic cycles of at most 5 sec between speeds of rotation and a second speed of rotation and/or to be rotated during continual acceleration at continually different speeds of rotation. A device for carrying out the method, such as a drag- or dip-finishing machine, includes a control device to impose speed of rotation profiles of the aforementioned type on a rotary drive workpiece holders, on which the workpieces can be clamped, or on a container containing the bed of granular material during the operation.
