Abstract

The invention discloses a non-rotation optical array coarse-fine integrated progressive grinding method. The method comprises the steps that 1, structure outlines of a precision structuring coarse grinding diamond grinding wheel and a precision structuring superfine diamond grinding wheel and the structure of a separating plate are designed and manufactured; 2, the precision structuring coarse grinding diamond grinding wheel, the separating plate and the precision structuring superfine diamond grinding wheel in the step 1 are sequentially installed on a machine tool main shaft, and a machinedworkpiece is fixed to a machine tool working table; 3, grinding wheel in-place correction is carried out; 4, profile modeling coarse grinding is carried out, wherein a profile modeling grinding methodis adopted, and the precision structuring coarse grinding diamond grinding wheel is used for coarse grinding; and 5, tangent track progressive precision operation is carried out, wherein along the progressive grinding track, a precision structuring fine-grit or ultra-fine-grit diamond grinding wheel is used for conducting progressive grinding on the workpiece surface, and semifinishing and finishing of the overall microstructural array surface profile are efficiently completed through one grinding circulation.

Description

technical field [0001] The invention relates to a grinding method of a non-rotating optical array, in particular to a coarse-finish integrated progressive grinding method of a non-rotating optical array. Background technique [0002] As a type of microstructure surface, non-rotating optical array has a more complex surface structure than other microstructures. It is often used as a key component in the field of modern optics and communication. Non-rotating optical array optical elements can greatly simplify the system The composition of the non-rotary optical array is often high in processing accuracy. The unit spacing of the array structure is generally at the millimeter or micron level, and the surface shape accuracy and surface roughness requirements are at the sub-micron level and nanometer level respectively. Array, the accuracy of non-rotating optical array parts is more difficult to guarantee. However, since ultra-precision grinding is currently the most effective me...
