Abstract

PURPOSE: To provide a product of high accuracy and quality, by providing a device for securing a slender workpiece such as a timepiece hand as the workpiece is curved along the shape of the recess of a table and by providing an intermittent moving device, to perform continuous rapid rectilinear cutting.
CONSTITUTION: A tool is secured on a rotating tool holder. A table 9 having an arc-shaped recess on its top is provided so that the table is opposed to the tool. A flat thin sheet workpiece 10 is secured as it is curve along the recess of the table. The tool on the holder is moved down as the tool is revolved. Since the center of curvature of the recess and that of revolution of the tool are made coincident with each other, the workpiece 10 can be rectilinearly cut. A device 30 is provided to intermittently move the workpiece 10 at a prescribed stroke. According to this constitution, continuous rapid rectilinear cutting is enabled and a product of high accuracy is provided.
