Method and device for producing non-cylindrical bores with at least one recess by honing

A honing tool has a tool body and shells disposed on the tool body. Honing stone sets each provided with two or more honing stones are provided. The shells each support one of the honing stone sets. Guide bars of the honing tool are placed against the bore and a portion of the bore is conically honed with decreasing stroke of the honing tool, wherein a lower reversing point of the honing tool remains substantially unchanged. Honing is terminated as soon as an upper reversing point has reached a predetermined terminal value. Alternatively, a portion of the bore is conically honed with a constant stroke of the honing tool, wherein reversing points of the stroke of the honing tool remain substantially unchanged and a feeding force pressing the honing stones against the bore is controlled as a function of a position of the honing tool in the bore.

Honing method and inner cam with C-shaped cross section

An inner cam has a substantially C-shaped cross section, an arcuately shaped inner circumferential surface of which is ground with high precision by such a honing method. The inner circumferential surface has a discontinuous portion. The honing method includes a fixing step and a grinding step. A plurality of inner cams, in which openings are provided between both ends thereof in the circumferential direction, are stacked, and the arcuately shaped inner circumferential surfaces thereof are subjected to grinding. In the fixing step, the relative positions of the plurality of inner cams are fixed such that a resultant force against the inner cams arranged on both end sides in the stacking direction, and a resultant force against the inner cams arranged on a central side in the stacking direction are opposed to each other mutually at a center location of the stacking direction.
