COMBINATION TYPE GRINDING DISC Russian patent published in 2005 - IPC

FIELD: machine engineering, possibly effective preliminary and finish working of blanks by means of abrasive disc.

SUBSTANCE: abrasive disc includes body with large-grain abrasive layer rigidly secured to it and spring-loaded movable inserts with small-grain layers. Mechanisms for radial motion of each movable insert include two pneumatic cylinders with mutually normal axes. Cylinders whose axes are parallel relative to axis of disc are joined to wedge type clamp that fixes spring-loaded inserts with small-grain abrasive layers. Invention provides possibility for finish grinding by means of disc with spring-loaded fixed inserts and for dwelling by means of said inserts.

EFFECT: desired accuracy of dimensions, preset macro- and micro-geometry of ground surfaces.
