Abstract: A material machining center for the machining of workpieces of varying size and of various materials has a worktable supported by a base assembly. The worktable has a vacuum table for immovably holding the workpiece during the machining thereof. The machining center also has a gantry assembly movably mounted on the worktable, the gantry assembly further has a workhead assembly movably mounted thereon and a machining tool adapted for movement. The movements of the gantry assembly, the workhead assembly and the machining tool define a coordinate system having an X, Y, and Z axis, respectively. The machining center further includes a means for controllably inclining the worktable relative to the base assembly whereby dust and chips created during the machining of the workpiece fall from the workpiece to the floor.

Abstract: A material working machine for edge finishing of workpieces of different sizes and shapes and of different materials has a material work station supported by a table like construction with a mechanical cutting tool mounted at the work station. The machine includes a workpiece feeding assembly comprised of a pair of resilient juxtaposed feeding belts having opposed gripping surfaces adapted to grip the opposite faces or sides of a workpiece to feed the workpiece across the working station as the resilient belts are moved. An adjustable pressure plate is mounted behind the feeding surface of each belt and can be moved toward or away from the opposite belt so as to be able to adjust the pressure exerted by the belts on the workpiece and also to accommodate workpieces of varying thickness.
