Abstract:
Apparatus for dressing a peripheral portion of a grinding disc comprising, in combination:(a) a bearing body including a free slide support and a blocking section, said bearing body slidably receiving a guide bar for sliding of the guide bar along a longitudinal axis;(b) an adjusting device operatively associated with said bearing body and with said guide bar to selectively adjust longitudinal position of the guide bar relative to the slide support by fine increments in the range of accuracy of about ten thousandths of an inch or more;(c) a lateral arm pivotably secured to a front end portion of said bar by a pivot for swinging the arm about a swing axis generally perpendicular said longitudinal axis;(d) a free end portion of the lateral arm remote from said pivot supporting a dressing tool including a dressing tip at a location laterally spaced from said longitudinal axis;(e) dressing radius calibrating means operatively associated with said free end portion for selectively adjusting and fixing the distance of the dressing tip from said swing axis to calibrate the radius circumscribed by said dressing tip at the circumference of an associated grinding disc.
