    Abstract: Printed circuit boards are moved in a conveyor with the underside of flat boards spaced a prescribed distance above the top surface of a rotating cutting disk. In order to protect the circuit patterns on the underside of the board and the board itself, a V-shaped wheel is loosely rotatably supported on a shaft with the wheel being in front of and orthogonal to the cutting disk. The height of the wheel is adjusted such that the uppermost point on the circumference thereof is in the line of travel of the boards. Movement of a board that is bowed downward in the direction of the disk causes the wheel to roll on the underside of the board and to raise the board above the top of the cutting disk. In this manner, the underside of warped circuit boards is maintained at least a prescribed distance above the top surface of the cutting disk as the board moves over the leading - cutting edge of the latter and component leads are trimmed thereby. Weak compression springs on either side of the wheel allow it to move sideways when it contacts a component lead. The spacing between the wheel and the front edge of the cutting disk is also adjustable.

    Abstract: In realizing the present method a ring-shaped tool is used with the cutting edge formed at the intersection of its inner and end surfaces, said tool is slipped over an article to be machined and positioned at an angle to the longitudinal axis of the article, the angle being selected depending on the curvature of the work surface, and then the cutting tool and the product are given a relative motion to provide for the interaction of the tool and the surface of the article being machined, such that the article moves only progressively, while the cutting tool is only rotating. In an installation for removing production-caused excess metal from curved surfaces of long-sized articles by the present method, the tool is ring-shaped with the cutting edge at the intersection of its inner and end surfaces, means for fixing the cutting tool comprises a holder rotating together with the tool around the article in the course of machining and provided with devices for inclining the holder in relation to the longitudinal axis of the article and for fixing it in the inclined position, while the holder with the cutting tool accommodates a support for positive pressing of the article against the cutting edge of the tool, and means for relative displacement of the cutting tool and the article is represented by a device imparting to the tool and the article such relative motion that the article moves only progressively, while the cutting tool is only rotating.
