System for the precision machining of rotationally symmetrical components

An arrangement for a fine machining of a component by vibratory grinding comprising:

• a container comprising an opening;
• an abrasive filling held by the container and comprising a plurality of abrasive particles and at least one of a physically active liquid and a chemically active liquid;
• a support arrangement supporting the container such that the container is vibratable;
• an unbalanced rotor having a drive operatively arranged to place the container into a rotationally-induced shaking motion comprising a defined amplitude and frequency;
• and
• a holding device for fastening the component horizontally within the container with one degree of freedom of movement relative to the container, the one degree of freedom of movement defined by a rotational center line of the component, the component being fastened within the container such that the component is at least partially immersed in the abrasive filling at regions to be processed;
• wherein the container comprises a substantially rotationally symmetrical configuration and is arranged with a center line extending vertically, a peripheral upper container edge of the container being arranged at a height which is above the component when the component is fastened by the holding device within the container.

A method for fine machining a component by vibratory grinding comprising:

• arranging a container having a substantially rotationally symmetrical configuration such that a center line extends vertically;
• providing the container with an abrasive filling, the abrasive filling comprising a plurality of abrasive particles and at least one of a physically active liquid and a chemically active liquid;
• fastening the component immovably relative to the container with a holding device such that the component is arranged horizontally within the container and is at least partially immersed in the abrasive filling at regions to be processed, a peripheral upper edge of the container being arranged at a height which is above the component;
• supporting the container with a support arrangement which allows the container to vibrate;
• and
• providing a rotationally-induced shaking motion to the container by rotating an unbalanced rotor with a drive, the rotationally-induced shaking motion comprising a defined amplitude and frequency.
