Abstract (en)

[origin: EP0219825A2] In the honing process, which is suitable in particular for blind holes or stepped bores, a honing tool (11) is moved into the bore (40) with retracted, that is non-expanded, honing layers, is expanded to the finished size in or behind the bore and performs its working stroke during the return stroke (direction 39). Chip removal takes place in a cutting zone (33) and the calibration to the finished size takes place in the finishing zone (34). The tool has pivotably arranged honing sticks. In a variant, guide strips firmly arranged between the adjustable honing sticks and having an anti-wear layer can be provided. Provision is also made to work with oscillating short strokes to machine the bottom area of a blind hole. <IMAGE>
