Description

technical field [0001] The invention relates to a precision grinding machine and a polishing machine tool, in particular to a compound grinding and polishing machine tool suitable for processing optical elements. Background technique [0002] Manufacturing is the pillar industry of the national economy, and grinding is an important field of manufacturing technology. It is the most effective and widely used basic technology for precision machining and ultra-precision machining in modern machinery manufacturing. [0003] The traditional ultra-precision grinding machine is used to process optical components. Although the processing precision is high, the processing efficiency is high, and the surface error is small, the processed optical components cannot meet the requirements of practical applications, and further polishing is required to make the processed optical components Optical components meet the precision requirements for practical applications (see references: Zhang N...

[0003] The traditional ultra-precision grinding machine is used to process optical components. Although the processing precision is high, the processing efficiency is high, and the surface error is small, the processed optical components cannot meet the requirements of practical applications, and further polishing is required to make the processed optical components Optical components meet the precision requirements for practical applications (see references: Zhang Ningning et al. Parallel grinding of non-axisymmetric aspheric optical components surface topography, Intense Laser and Particle Beams, 2012, 24(6): 1391-1395 and paper: Wang Zhenzhong et al. Research on high-precision surface grinder processing system for large-diameter optical components, China Mechanical Engineering, 2012, 23 (1): 79-84)

Since the polishing process needs to move and clamp the optical components multiple times, this will not only cause repeated positioning errors, but also easily cause damage to the optical components, and seriously affect the processing efficiency
