Ceramic CBN grinding wheel arc-shaped surface dressing method and device for ball groove grinding

The invention provides a ceramic CBN grinding wheel arc-shaped surface dressing method and device for ball groove grinding. A dressed grinding wheel spindle and a tool grinding wheel spindle can act according to corresponding action parameters under the control of a central processing unit, wherein the dressed grinding wheel spindle can be driven by an X-axis workbench, a Y-axis workbench and an A-axis rotation table, the X-axis workbench can reciprocate along the X axis at a constant speed, the Y-axis workbench is arranged on the X-axis workbench and can reciprocate along the Y axis at a constant speed, the A-axis rotation table is arranged on the Y-axis workbench and can freely rotate along the A axis, and the dressed grinding wheel spindle is arranged on the A-axis rotation table. The tool grinding wheel spindle is driven by a V-axis workbench capable of doing constant-speed reciprocating motion in the V-axis direction parallel to the X axis. According to the ceramic CBN grinding wheel arc-shaped surface d
