Abstract

The invention discloses a precise machining machine tool for small-caliber rotating shaft symmetrical optical curved elements. The precise machining machine tool is provided with a machine body with a vibration reducer. A first slide table driven by a first linear motor is mounted on one side of the machine body, and is provided with a workpiece main shaft. Correspondingly, a second slide table driven by a second linear motor is mounted on the other side of the machine body, and is provided with a first rotating table; and an inclined shaft fine milling device, an inclined shaft electroheological polishing device, a single-point diamond turning device and a detecting device are annularly arranged on the rotating table. The precise machining machine tool is fast and convenient in switching of different machining modes, can perform the in-situ measurement and the compensation machining on workpieces, and achieves good controllability of machining paths; the workpieces are once clamped in the machining process, so that the accumulated errors are reduced, the auxiliary labor hours are reduced, and the machining precision and the machining efficiency are improved; and the precise machining machine tool adapts to machining and detection of the workpieces with different surface shapes and multiple materials, and can effectively prevent the interference phenomenon between cutters and the workpieces in machining of concave surfaces of the workpieces.

Description

technical field [0001] The invention belongs to the technical field of optical precision machining, and in particular relates to a precision machining machine tool for small-diameter rotating axis-symmetrical optical curved surface elements. Background technique [0002] With the rapid development of optoelectronic information, automotive, biological, medical, security, military and aerospace industries, small-diameter rotating axisymmetric optical curved elements are increasingly widely used in various high-quality imaging systems, and the demand has increased sharply. In order to meet the requirements of high-precision imaging in the above-mentioned fields, the surface shape of the small-aperture rotating axisymmetric optical surface element is required to achieve sub-micron level shape accuracy, and its surface is required to achieve nano-level surface roughness and minimal sub-surface damage. [0003] At present, there are two main methods for precision manufacturing of ...
