Method and device for the surface finishing of workpieces

A method for the surface finishing of workpieces, the method comprising the steps of:

• providing a workpiece holder comprising a rotary drive;
• providing a container comprising a bed of granular grinding and/or polishing material;
• detachably fastening a workpiece on the workpiece holder;
• moving the workpiece into the container;
• continuously changing a rotational speed of the workpiece with the workpiece holder connected thereto via the rotary drive from a start of a grinding and/or polishing process to an end of the grinding and/or polishing process after the workpiece is moved into the container, wherein the workpiece holder with the workpiece is rotated in periodic cycles of at most 5 seconds between at least one first speed of rotation and at least one second speed of rotation, wherein at least one of the periodic cycles is defined as consecutive durations during the surface finishing, during which the workpiece holder with the workpiece is accelerated and decelerated once while rotating the workpiece holder with the workpiece between the at least one first speed of rotation and the at least one second speed of rotation.

• providing a container comprising a bed of granular grinding and/or polishing material;
• detachably fastening a workpiece on the workpiece holder;
• moving the workpiece into the container for carrying out a granular grinding and/or polishing process;
• rotating the workpiece holder with the workpiece at a rotational speed after the workpiece is moved into the container from a start of the granular grinding and/or polishing process to an end of the granular grinding and/or polishing process, wherein the rotational speed is continually varied from the start of the granular grinding and/or polishing process to the end of the granular grinding and/or polishing process, wherein the workpiece holder with the workpiece is rotated in periodic cycles of at most 5 seconds between at least one first speed of rotation and at least one second speed of rotation, wherein at least one of the periodic cycles is defined as consecutive durations during the surface finishing, during which the workpiece holder with the workpiece is accelerated and decelerated once while rotating the workpiece holder with the workpiece between the at least one first speed of rotation and the at least one second speed of rotation.
