ABSTRACT:
A belt grinding machine wherein the belt is maintained at a selected position on the drive and idler pulleys and the drive and idler pulleys are supported from a column which is oscillated relative to the work piece holder. The drive pulley or contact wheel is directly driven by a drive motor which is also supported from the oscillating column. The column is supported for movement transverse to an elongated bed which supports a reciprocating table. The reciprocating table holds the article to be ground. The speed and distance of movement of the table and column are variable. The grinding belt is positioned automatically, through photo sensors and hydraulic controls, on the idler and drive pulleys. The idler pulley is supported by bearings from an eccentric spindle which can be rotated in steps by a hydraulic cylinder to change slightly the idler pulley alignment for proper steering of the belt. When the belt moves from its desired position, it is slowly moved back to the desired location. During operation the eccentric spindle is moved slightly and after a slight time delay the belt position is again sensed to determine if further adjustment is necessary.
