Abstract: A cam controlled contour turning, facing, and boring machine tool having a frame on which a first slide is mounted for reciprocable movements along a generally horizontal path and a second slide mounted on the first slide for movements with the latter and for lateral movements relative to the first slide either normal to or at an inclination of less than 90.degree. to the path of movement on the first slide. On the frame is mounted supporting means for one or more workpieces and on the second slide is mounted tooling engageable with the workpieces. The movements of the slides are effected by two cams, one of which controls the movements of the first slide and the other of which controls the movements of the second slide, the cams being rotated simultaneously by driving means mounted on the first slide.

Abstract: A grinding machine for grinding surfaces of workpieces supported on a frame comprises a first slide mounted on the frame for reciprocating movements along a fixed length path toward and away from the workpieces, the first slide supporting a second slide which carries grinding wheels. The second slide is adjustably mounted on the first slide for movements with the latter so as to effect movement of the grinding wheels into and out of engagement with the workpieces and for movements relative to the frst slide so as to compensate for erosion of the grinding wheels caused by grinding or dressing operations. The machine includes dressing tools for the grinding wheels and which are operable in timed relation to the reciprocating movements of the slides to effect dressing of the grinding wheels.
