Technical field [0001] The invention belongs to the technical field of precision processing, and relates to quartz glass spherical parts, in particular to a precision grinding tool and process for quartz glass hemispherical parts. Background technique [0002] The hemispherical gyroscope harmonic oscillator is the core component of the hemispherical resonator gyroscope, which belongs to the quartz glass spherical parts. figure 1 , When developing high-precision gyroscopes, the resonator must be made of fused silica glass. Due to the small wall thickness of the hemispherical resonator and the difficult processing of the hard and brittle materials of fused silica glass, the precision molding and processing technology of the hemispherical gyro resonator has always been a bottleneck restricting its development. [0003] At present, the molding process of the hemispherical resonator generally adopts milling or rotating ultrasonic processing methods. Since this type of equipment can be e...

Problems solved by technology

However, for traditional grinding equipment, only 2-3 grinding wheels can be installed at most at one time, and the grinding wheels are worn to a certain extent when processing parts of this material, so only semi-finishing of the resonator can be performed, and it is difficult to achieve hemispherical quartz resonance Sub precision grinding

However, there is a problem of precise alignment in the processing scheme of separating rough and fine grinding, so it is difficult to realize the precision machining of the hemispherical resonator by using the grinding scheme
