Abstract
A dressing device for shaping grinding wheels for use in manufacture of gear wheels and the like, comprises an arm (4) supported intermediate its ends by a spherical bearing (5,9) for free angular movement about a fixed point (P) on the arm axis and for rotation about the axis. The working element (2) e.g. a diamond, is carried on the forward end of the arm and a control mechanism adapted for automatic electronic control is coupled to the rear end of the arm through a gimble (6,7). The control mechanism includes a pair of slide tables (17,20) having respective motors (18,21) for movement in mutually perpendicular directions (x,y) and a third motor coupled to a gear (24) fast with the arm for rotating the arm.
Claims9
A dressing device for profiling grinding wheels, comprising an arm with front and rear ends, and a longitudinal axis, bearing means supporting said arm intermediate said front and rear ends thereof for free angular movement of the arm about a predetermined fixed point on said longitudinal axis and for rotation about said axis, means carried on said arm at said front end thereof for supporting a working element, and control means coupled to said arm rearwardly of said predetermined fixed point for controlling angular displacement of the arm about said fixed point and rotation of said arm about said longitudinal axis, said control means comprising means for rectilinear movement in two mutually perpendicular directions in a plane substantially normal to said axis of the arm.
