Document Type and Number:
Japanese Patent JPH0151290
Kind Code:
B2
Abstract:
A sawtooth grinding machine has a single pivotally mounted grinding head for grinding both the face and back of teeth, such as in a circular saw blade. The grinding wheel is a composite member formed of a disk wheel and a cup wheel. The disk wheel is shaped to fit into narrow gaps between teeth when grinding the face of a tooth. The cup wheel has a smaller diameter than the disk wheel and has an abrasion-coated ring on its outer circumference for grinding the back of a tooth. A spindle shaft mounts the grinding wheel on the grinding head. The angular displacement of the grinding head for different grinding positions can be reduced as compared to known arrangements. The grinding head is supported for translatory movement in two directions extending perpendicularly of one another and also for rotation about two axes disposed at right angles to one another.
