精密机械装备的精度水平,以精密机床和仪器为例,目前已达到0.1微米以内。如美国莫尔(Morre)专用工具公司生产的M-18AG型镜面车磨床、日本丰田工机生产的AHP 50-32型超精密车床,主轴回转精度达到了0.025微米,加工有色金属零件的光洁度为▽13～▽14;西德海登哈恩(Heidonhain)公司生产的DS200/400型转台,主轴回转精度为±0.2微米,示值误差为0.1角秒;英国兰克泰勒霍布森(Rank Tlor ay Hobson)公司生产的泰莱圣屈立克(Talycentric)转台有各种规格,其中主轴回转精度最高达±0.013微米;日本东京精密公司生产的圆度仪达到±0.01微米。我国也生产了不少精密机械产品,如
Precision machinery and equipment of the level of precision to precision machine tools and equipment, for example, has reached 0.1 microns or less. Such as the United States Mor Mori special tool company M-18AG mirror car grinding machine, Japan’s Toyota machine AHP 50-32 production of ultra-precision lathe, the spindle rotation accuracy of 0.025 microns, the processing non-ferrous metal parts finish ▽ 13 ~ ▽ 14; DS200 / 400 turntable manufactured by Heidonhain company with spindle rotation accuracy of ± 0.2 μm and indication error of 0.1 arcsecond; Rank Tlor ay Hobson’s Talycentric turntable is available in a variety of sizes, with spindle slew accuracy of up to ± 0.013 μm and Japan Tokyo Precision’s roundness meter up to ± 0.01 μm. China has also produced a lot of precision machinery products, such as
