Abstract
A toolholder turret (3) is movable in the X and Z directions relative to a work table (2) so that each of the grinding tools (9a, 10a, 11a 12a) can be presented to machine a surface of a workpiece (6). A support (20) of a truing unit (4) bears a rotary body (22), one arm (23) of which is provided at the end with a follower, while two vertical arms are provided with diamonds. The exact positions of the truing tools relative to a reference, which may be constituted by the detecting surfaces of the follower, are detected by means of a further follower (18) integral with a further table (13). Measurements taken by displacement of the latter follower are stored in a memory. Other measurements relating to the actual sizes and shapes of the grinding tools are likewise taken through displacement of the further table so that these tools are sensed by the detecting surfaces of the first-mentioned follower. By means of these data, a truing program can be particularized, which then proceeds automatically and imparts a specific desired shape to the grinding wheels. Thereafter, the precision grinding operation on the workpiece can be automatically controlled.
