Title: Grinding surface compensational method for grinding machine
Inventor: TATSU KUNIYOSHI
IPC: B24B17/04
Filed: 1987-03-05
Abstract: PURPOSE:To finish an accurate curved surface even if a grindstone is one-sidedly worn out, by moving a peripheral edge of the stone after a circular surface, reading a point coordinate as an electric signal at each circular surface, while originating compensation data at each grinding point of the stone, and storing these data in memory. CONSTITUTION:Two recess and projection circular surfaces are displayed on a scope of an indicator 3 where a workpiece and a grindstone are projected, a peripheral edge of the stone is relatively moved to some extent after the circular surface, and at this process, a point coordinate of the stone is converted into an electric signal by pulse generators 9 and 10 at each circular surface, whereby compensation data at each grinding point of the stone are originated at a central processing unit 1, and these data are stored in a memory 7. With this constitution, numerical control data for setting a work grinding curved surface are compensated with these compensation data compensating for variations in a radius in the sectional direction of the stone peripheral edge. Thus, even if the stone is one-sidely worn out, an accurate curved surface is finishable and, what is more, dressing frequency becomes lessened and consumption of the stone is abatable.

Title: Method and device for rolling
Inventor: SHINTANI SADAHIKO
IPC: B21B1/38
Filed: 1985-03-14
Abstract: PURPOSE:To improve the flatness of a rolling stock by preestimating a camber in the width direction of a rolling stock, due to a working heat at the time of rolling, and rolling the stock in a state of providing a camber in the reverse direction to the preestimated one. CONSTITUTION:An upper work roll 3 of rolling device is formed so that its diam. decreases from its both sides to its center, and a lower work roll 4 is formed so that its diam. increases from its both sides to its center. The radii of curvature in the width direction of rolls 3, 4 are set respectively, so that a rolling stock W is cambered in the reverse direction by an amount approximately equal to the camber due to the working heat produced at the time of rolling the stock W. When the stock W is continuously rolled by introducing it into between the rolls 3, 4, the camber due to the working heat of stock W is canceled, and the surface of stock W is flattened as a result. Accordingly, the flatness of a rolling stock is improved by this method.
