Description

technical field [0001] The invention relates to the field of precision machine tool processing, in particular to a real-time compensation device and method for comprehensive error of a spindle used for processing the microstructure of a roller on an ultra-precision machine tool. Background technique [0002] The microstructures on many optical devices are processed by roll forming, and the rollers used in roll forming are mostly processed by single-point diamond ultra-precision machine tools. Due to the very small size of the microstructure, the requirements for the shape accuracy and surface roughness of the structure are very high, which also puts forward very high requirements for the machining accuracy of the machine tool. [0003] Spindle is an important component widely used in ultra-precision machine tools, and its motion accuracy has decisive significance for processing quality. With the development of the air bearing spindle, the precision of the spindle has been g...
