SIDE TRIMMING A WEB PLATE

摘要

A side edge surface of a web plate is trimmed by or machined after feeding a milling cutter into the side edge surface of the web plate, which cutter has on its outer peripheral surface cutting edges at a predetermined angle with respect to its rotary axis, and driving the milling cutter in rotation. The rotary axis of the milling cutter is a plane which is kept parallel to a desired machined surface of the side edge surface of the web plate, and the angle formed between the cutting edge of the milling cutter and the side edge surface of the web plate is limited to within 55 degrees to 125 degrees.
