Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as Figure 1-2 As shown, when starting processing, first start the computer and electronic control system components, air pump and vacuum generator components, the vacuum chuck starts to have a certain suction force, and then fix it on the special vacuum chuck according to the size of the KDP crystal part to be cut. After adjusting the special arc-edge diamond tool and the initial processing distance with the KDP crystal part, the spindle motor starts to rotate, and the arc-edge diamond tool is driven by the special cutterhead connecting shaft, the special cutterhead and the special arc-edge diamond tool angle adjuster. The set working radius follows the high-speed rotation of the spindle motor. At the same time, the hydrostatic guide rail linear drive motor starts to work. The high flatness worktable and the hydrostatic guide rail ...

Abstract

The invention relates to a vacuum chuck for a KDP crystalline material. A special vacuum chuck high-strength fixed support is mounted on a high-flatness workbench and a liquid hydrostatic guideway support plate assembly through a special vacuum chuck high-strength fixed support fixing nut and bolt assembly; vacuum chuck balance adjusters are distributed at four corners of a vacuum chuck balance adjusting plate, grooves shaped like dual nested rectangles have consistent width and depth, each groove is communicated through a vent hole connected with a special vacuum chuck air-guide pipe, and the special vacuum chuck air-guide pipe is connected with an air pump and a vacuum generator assembly. When the air pump and the vacuum generator assembly operate, the grooves shaped like dual nested rectangles in the surface of the vacuum chuck are in a vacuum state, so that the vacuum chuck has suction to fix KDP crystalline parts. The vacuum chuck is also applicable to all parts with non-machining surfaces being planes, and the clamping accuracy is guaranteed; non-uniform force clamping deformation does not exist, so that the machining residual stress of the parts is greatly reduced.

Description

technical field [0001] The invention relates to a fixing device for KDP crystal material, which can realize ultra-precision processing of KDP crystal material with high precision, high efficiency and low cost. Background technique [0002] KDP crystal is a kind of inorganic electro-optic nonlinear optical crystal with excellent performance. It is the only crystal material that can grow in large size at present, and has large nonlinear optical coefficient, high laser damage threshold, wide transmission wavelength range, and optical uniformity. It has the advantages of good performance and easy phase matching. Therefore, KDP crystals are widely used in laser frequency doubling conversion, photoelectric modulation, fast photoelectric switching and other high-tech fields of laser and nonlinear optics, and have an important position in inertial confinement fusion systems that cannot be replaced by other crystal materials. However, the KDP crystal itself has a series of character...
