Abstract
A tool spindle for a honing machine includes a bowl-shaped holder having a circumferential peripheral wall connected to a bottom part. The bowl-shaped holder is configured to hold a honing ring on an inside of the bowl-shaped holder. At least one expansion element is formed on the inside of the bowl-shaped holder along an inner surface of the circumferential peripheral wall. The at least one expansion element radially clamps and centers the honing ring inside the bowl-shaped holder. A hydraulic chamber is disposed in the bottom part of the bowl-shaped holder. At least one hydraulic line is connecting in fluid communication the at least one expansion element and the hydraulic chamber. A single adjustment element is movable in relation to the bottom part of the bowl-shaped holder, where the single adjustment element is in fluid communication with the hydraulic chamber.
