Abstract

The invention relates to an ultraprecise grinding head device which comprises a grinding head (1) and an exciting device (2), wherein the grinding head (1) is connected with the exciting device (2); the exciting device (2) drives the grinding head (1) to rotate and transmits magnetism to the grinding head (1); a gas passage (3) is arranged inside the exciting device (2); the gas passage (3) is communicated with the grinding head (1); a gas flow in the gas passage (3) passes through the grinding head (1) and is sprayed out from an external surface of the grinding head (1). The ultra-precision grinding head device solves a problem that a magnetic fluid is difficult to effectively replace, and the ultraprecise grinding head device is provided.

Description

technical field [0001] The invention relates to the technical field of ultra-precision machining, in particular to an ultra-precision grinding head device. Background technique [0002] Micro-aspheric optical parts are generally in the range of a few millimeters to tens of millimeters in diameter, and are very important optical parts. In terms of military use, the optical systems of photoelectric instruments such as laser guidance systems, radar ranging systems, aviation and aerospace telescopic camera systems, and infrared thermal imaging engineering are widely used in various optical materials such as micro-aperture aspheric mirrors. And it is more widely used in civilian use, such as photoelectric lenses, infrared remote monitoring mirrors, video recorder lenses, laser video disc devices, X-ray lenses for medical diagnosis, indirect ophthalmoscopes, endoscopes, progressive lenses, digital cameras, CCD camera lenses, etc. Products, these require a large number of small-ca...
