Abstract
A blade surfacing machine for precisely honing a pair of intersecting surfaces on an extruder blade. The working surface of a rotating honing stone is maintained in spring-biased contact with a precisely leveled guide surface to achieve linear uniformity of the blade. A workholder table is pivotable about a horizontal axis and may be pin locked at selectable angles to produce blades having a selective angle of intersection between the two honed surfaces.
