Problems solved by technology

However, at this scale, traditional milling parameters and processing techniques are no longer suitable for micro-milling. For example, because the diameter of the micro-milling cutter is small, in order to achieve a certain line cutting speed, it is often necessary At the same time, people can hardly see the blade during the rotation with the naked eye, so it is difficult to perform the knife setting operation and real-time observation and monitoring of the processed surface quality with the naked eye. Microscope-assisted tool setting and real-time monitoring technology are used in micro It is very important in milling
In particular, in nuclear fusion ignition devices, if micro-defects are generated on the surface of the large-diameter KDP crystal element, it will grow rapidly during the subsequent high-energy laser targeting process, which greatly reduces the laser damage threshold of the KDP crystal and shortens the use of the crystal. life

Description

technical field [0001] The invention relates to an ultra-precision three-axis linkage micro-milling device. Background technique [0002] At present, micro-milling is an important advanced manufacturing technology, which plays an important role in the fields of electronics, biology, and national defense. Usually the object of micro-milling research is that the processing feature size is on the order of microns to sub-millimeters, and the diameter of the milling cutter is generally less than 0.5mm. However, at this scale, traditional milling parameters and processing techniques are no longer suitable for micro-milling. For example, because the diameter of the micro-milling cutter is small, in order to achieve a certain line cutting speed, it is often necessary At the same time, people can hardly see the blade during the rotation with the naked eye, so it is difficult to perform the knife setting operation and real-time observation and monitoring of the processed surface qual...
