Abstract (en)
A drill grinding machine is proposed wherein a drill holder is supported for angular adjustment about two mutually perpendicular axes 15, 16 and is pivotal about a fixed axis 14. Adjustment about the respective mutually perpendicular axes 15, 16 determines the drill point angle and point relief whilst pivotal motion about the fixed axis 14 moves the drill point into and out of cooperative relationship with an abrasive surface 12 in a correct geometrical disposition for requisite point grinding.
