Abrasive surfacing machine

Apparatus for deburring workpieces, including relatively small parts, comprising:

• frame means;
• workpiece conveyor means carried by the frame means for simultaneously carrying a plurality of individual workpieces thereon for movement through a deburring area, the workpiece conveyor means comprising an endless, substantially planar workpiece carrying surface of predetermined width defined by first and second longitudinal side edges, the workpiece conveyor means further comprising means for retaining workpieces having a dimension less than said predetermined width in a fixed position on said workpiece carrying surface at substantially any point thereon between said first and second edges for movement through the deburring area;
• and a deburring head carried by the frame means in said deburring area in opposed relation to said workpiece carrying surface, the abrasive surfacing head comprising
• rotatable disk means having a substantially planar surface that is substantially parallel to the workpiece carrying surface of the workpiece conveying means, said disk means having a diameter that is at least substantially 11/2 times the predetermined width of the workpiece carrying surface;
• and a resilient deburring medium of substantially uniform thickness secured to the planar surface of the disk means, the resilient deburring medium being sized and configured to present to workpieces as it is rotated a resilient deburring surface having a diameter that is at least substantially 11/2 times the width of the workpiece carrying surface, whereby each workpiece is engaged multidirectionally by the resilient deburring medium irrespective of its fixed position on the workpiece carrying surface.
