摘要： Method and apparatus for broaching an outer surface of a resin layer of a resin-coated part whose external side surface is coated with the resin layer, wherein a backing plate is used to back the resin-coated part such that the plate is held in contact with an end face of the part at which a movable broach terminates a broaching cut in a direction along the outer surface of the resin layer. The backing plate has an external profile similar to a cutting edge contour of the broach. The backing plate is positioned on a work bed of the broaching apparatus such that its external profile is inwardly spaced from the cutting edge contour of the broach a plane perpendicular to the direction of movement of the broach. The backing plate, which forms a part of a work-holding fixture, serves to protect the resin layer from breakage, chipping or other defects at the end of a broaching pass along the outside of the resin-coated part.

摘要： Machine tool structure designed to reduce the noise incident to operation. The invention is illustrated and described as applied to a vertical broaching machine in which the frame structure is modified by supporting the operating components on a vertical slab or thick plate reinforced with longitudinally extending ribs and including an open truss type support rather than the conventional hollow or enclosed columnar frame in common use.
