This paper describes the way of ultrapreciso turning aspherical optical reflectors with diamond tools and analyzes the factors whih influence surface finish of mirrors, circulity and figure accurancy. This paper also introduces the influence of machine spindle asynchronous error on surface finish and analyzes the reason for producing asynchronous error motion and the method of reducing asynchronous error value systematically. In order to get rid of the influence of workpiece chucking distortion on machining accuracy of mirror, we used an approaching method from poiat to point to get rid of workpiece chucking distortion step by step4,so that the clrculity of mirror achieved were 0.3μm in machining.

文章介绍了用金刚石刀超精车削光学非球面镜的方法。分析了在超精车削中影响镜头表面光洁度和圆度、面形精度的因素,其中介绍了机床主轴的非同步误差对表面光洁度的影响,并系统分析产生非同步误差运动的原因和降低非同步误差值的方法;为消除工件装卡变形对加工镜头精度的影响,加工中采用逐点趋近法分步消除工件的装卡变形,从而达到镜头圆度为0.35μm的高精度。

A technique of preparing TEM Samples of Carbon fibres and C-C Composites has been investigated. Microtomy have many advantages. A Comparision has been made with ion bombardment. Microtomy with a diamond Knife permits to prepare thin foils Samples with high transparency of electron, good parallelism and have a clean Surface. analysis has been done to identify the Artefacts introduced during the preparation of thin foils in TEM observations.
