苏联开发的AU-700、AU-1000、AU-1000M、AU-2000型精磨机主要用于大型光学零件工作表面的最终精密加工中,可适用于任何经抛光但未达到精度要求的面形修磨,使其表面的局部误差、带差及象散光得到消除。而且可在抛光过程中使表面实现二次方或高次方非球面化。整个加工及控制过程均由计算机按被加工面形所编制的程序进行,自动化程度很高。这一系列机床所能加工的最大零件直经分别为700mm、1000mm、2000mm。精磨后 The AU-700, AU-1000, AU-1000M, AU-2000 refiners developed by the Soviet Union are mainly used for the final precision machining of the working surfaces of large optical components and are suitable for any profile that is polished but does not meet the accuracy requirements Sharpen, so that the surface of the local error, with poor and astigmatism to be eliminated. But also in the polishing process so that the surface to achieve quadratic or high order aspheric. The entire process of processing and control by the computer by the processing of surface preparation of the program, a high degree of automation. The largest parts machined by this series of machine tools are 700mm, 1000mm and 2000mm respectively. After grinding
