Abstract

A grinding fixture for grinding the buttons in rock drilling button bits comprising a means in which the bit is intended to be anchored during grinding, a horizontally arranged disk rotatably driven about a vertical axis through the center of the disk on which the means rests, and an arm extending over the disk for centering a button which is to be ground so that the button will be concentric with the rotational axis of the disk, the arm being arranged displaceable along, and swingable about a vertical column, and a cup-shaped recess at the end of the arm, the shape of the recess substantially corresponding to the shape of the button.
