A radiusing dressing device adapted to dress the periphery of a grindstone to a part toroidal form. The device includes a spindle pivotable without backlash in an outer housing about a first axis, and means are provided for pivoting the spindle through a limited angle, in either sense, about said first axis. The outer housing is secured to a support via a first limiting chuck which is deformable in a first direction and has a high rigidity in a second direction perpendicular to said first direction, the spindle carrying at one end a right-angled diamond carrier through the intermediary of a second unitary chuck deformable in one direction and having a high rigidity in a perpendicular direction. Each of the chucks have a respective precision adjustment means adapted to place the respective chuck in tension and to deform it to provide, in the case of the first chuck, adjustment of the position, measured perpendicular to the first axis, of the first axis with respect to the support, and in the case of the second chuck, adjustment of the position of the diamond carrier with respect to the first axis. |
