machine for grinding or milling of convex and / or concave spherical surfaces

摘要

In a machine for the production of the surfaces of optical lenses, it is made, for the mounting of the spindle carries - tool 8, two elements 2 and 6 from which a first 2 is mounted pivoting on the frame 1 of the machine about an axis is tangential to the highest point of the spherical surface to be produced and can be n4 determined in a position, corresponding to an angle of inclination g appropriate to the radius of the spherical surface to be machined, a second element 6 for direct mounting of the spindle carries - tool 8 is mounted on this element 2 about an axis b which is located, from the axis a at a distance from the second element 2 can be n4 about the axis b in a position corresponding to an appropriate angle b to the diameter of the tool with respect to a line s through the axis b is the axis a
