摘要： PROBLEM TO BE SOLVED: To provide a grinding method for controlling the location and direction of grinding resistance imposed on a rotary grinding tool to a constant location and a constant direction by fixing a grinding point of a workpiece to be ground by the rotary grinding tool such as a rotary grindstone to one point, and to provide a grinding device for implementing the method.
SOLUTION: According to the grinding method, the rotary grinding tool 12 is arranged such that its rotation axis is inclined a predetermined angle θ with respect to a rotation axis of the axially symmetric workpiece 7 to be ground, and the workpiece 7 to be ground or the rotary grinding tool 12 is relatively moved so as to copy a desired machining shape while a front angular portion of the rotary machining tool 12 abuts on a machined surface 7a of the workpiece 7 to be ground. Further at least one of the workpiece 7 to be ground or the rotary grinding tool 12 is controlled in terms of rotation according to progress of grinding procedure such that the rotation axis of the rotary grinding tool 12 always coincides with a normal with respect to a grinding point E at which the front angular portion abuts on the machined surface 7a, as viewed in a direction orthogonal to a moving plane of the relative movement, to thereby grind the surface 7a to be machined so as to have a non-spherical concave surface.

摘要： PROBLEM TO BE SOLVED: To accurately process optical elements with an axis-symmetrical shape, an axis-asymmetrical shape, a free curve shape, or a plurality of them arranged in an array, and a molding die for molding them.
SOLUTION: When processing optical elements with a predetermined shape arranged in an array, a center of a workpiece 9 is aligned with a first rotation shaft 1 and mounted to it, and one shape arranged in an array not on a rotary center of the first rotation shaft 1 is rotated around the first rotation shaft 1. This rotation is offset by synchronously rotating a second rotation shaft 5 with a tool 8 opposed to the first rotation shaft 1 at an identical number of revolutions. A position of the shape arranged in an array is decided by a rotation starting angle of the second rotation shaft 5 relative to the first rotation shaft (C1 shaft) and a position in a radial direction of a linear axis X2 shaft 6 on the second rotation shaft (C2 shaft).

摘要： PROBLEM TO BE SOLVED: To obtain a precise optical element by molding the optical element apart from the misalignment and slant of an optical axis. SOLUTION: A figuration of the optical element is precisely made by forming a molding surface 1a and a molding surface 2a in an upper die 1 and a lower die 2 respectively. A taper part 1b is formed at the outside of the molding surface 1a of the upper die 1 by a predetermined angle θ concurrently with the molding surface 1a. Likewise, a reentering taper part 2b is formed at the outside of the molding surface 2a of the lower die 2 by a predetermined angle θ concurrently with the molding surface 2a. A pressure face part 1c which contacts with a pressing plate 7 of the upper die 1 is spherical where its apex is on the center line of the molding surface 1a of the upper die 1 so that a weight is applied at the one point when the optical element is molded. The thickness of the molded optical element is defined by fitting the taper part 1b to the taper part 2b. Since the misalignment and slant of the optical axis might arise when fitting the taper part 1b to along the taper part 2b while the lower die 2 is combined with the upper die 1, the misalignment and slant of the optical angle after molding is prevented according to the present invention because the taper part 1b is pressed in conformity with along the taper part 2b owing to the spherical figure of the pressure face part 1c of the upper die 1.
