Abstract
A grinding machine, preferably for sharpening circular saw-blades, has a machine frame that supports a device for supporting the saw blade, for fixedly clamping the blade, and for advancing the saw-blade tooth-by-tooth. The grinding attachment has two independent operating spindles or, which are preferably oriented perpendicular to one another, and support separate drives. The grinding attachment is mounted to pivot and be adjusted in three spatial directions. In a selected pivoting position, one of these spatial directions (Z direction) is oriented radially with respect to the saw blade. In this position, the axis of rotation of one spindle is oriented in the circumferential direction, and the axis of rotation of the other spindle is oriented in the radial direction. A grinding attachment of this type permits the hollow-grinding of tooth faces with grinding pencils that have a small diameter. A separate, high-speed motor serves to drive the grinding pencil.
