Abstract: A honing tool comprises a tubular tool body fastened with an end section in a tool shank and a cutting region on an opposite end section with at least one honing-stick accommodating opening. The dimensions of the honing-stick accommodating opening and of the honing stick are matched to one another so that the honing stick is accommodated in a radially movable manner, and essentially free of play in a circumferential direction of the tool body, between boundary surfaces of the honing-stick accommodating opening. A play-compensating device between the honing stick and the honing-stick accommodating opening comprises at least one elastically deformable supporting element which is supported with a pressure force, in a fitted state of the honing stick, on one hand on a side surface of the honing stick and on the other hand on a boundary surface, opposite the side surface, of the honing-stick accommodating opening.

Abstract: A supporting device for a plurality of adapter chucks for the precision grinding or polishing of optical components comprises a spindle shaft having a central bore for supplying one of a gas and a vacuum, at least one arm adjustably supported by a head of the spindle shaft and having a seating for an adapter chuck, and a flexible vacuum/gas line provided between the seating and the spindle shaft. The arm is adjustable as to its angle of inclination relative to an axis of the spindle shaft.

Abstract: A rotary honing tool includes a rotatable body member mounted on a shaft and having attached rotatable honing arms as well as a band or collar fitted about the body. The collar is engaged with the body by means of a lug on the collar fitted into a channel on the outside face of the cylindrical body. The collar may be rotatably displaced to control radial extention of the honing arms.
