Abstract
In a device for microfinishing both sides of disklike workpieces with plane and/or spherical surface, two tool spindles with two tools are provided on two orbit spindles; the two tools engage the two face-end surfaces of the workpiece. The tool spindles revolve, spaced apart by a certain distance, around the axes of the two orbit spindles. In this way, excellent micrographs and excellent grinding results are attained.
Claims22
A device for microfinishing or superfinishing both sides of disklike workpieces each having a peripheral face and one of a plane, spherical and plane and spherical surfaces, comprising:
- means for receiving a disklike workpiece with one of the surfaces noted along its peripheral face;
- a first orbit spindle defining an axis of rotation, a first tool spindle rotatably received in said first orbit spindle, said first tool spindle defining an axis of rotation which is spaced apart from the axis of rotation of said first orbit spindle by a first distance, and a first tool rotatably received in said first tool spindle for machining one surface of the workpiece;
- a second orbit spindle defining an axis of rotation, a second tool spindle rotatably received in said second orbit spindle, said second tool spindle defining an axis of rotation which is spaced apart from the axis of rotation of said second orbit spindle by a second distance, and a second tool rotatably received in said second tool spindle for machining the other surface of the workpiece;
- and
- means for rotating said first orbit spindle and said second orbit spindle.
A device for microfinishing or superfinishing both sides of disklike workpieces each having one of a plane, spherical and plane and spherical surfaces, and each defining a center point, comprising:
- means for receiving a disklike workpiece with one of the surfaces noted;
- a first orbit spindle defining an axis of rotation, a first tool spindle rotatably received in said first orbit spindle, said first tool spindle defining an axis of rotation which is spaced apart from the axis of rotation of said first orbit spindle by a first distance, and a first tool rotatably received in said first tool spindle for machining one surface of the workpiece;
- a second orbit spindle defining an axis of rotation, a second tool spindle rotatably received in said second orbit spindle, said second tool spindle an axis of rotation which is spaced apart from the axis of rotation of said second orbit spindle by a second distance, and a second tool rotatably received in said second tool spindle for machining the other surface of the workpiece;
- and
- means for rotating said first orbit spindle and said second orbit spindle, wherein the axes of said first tool and said second tool orbit around the center point of the workpiece.
