DC2000型钻石切工自动分析仪的测量精度分析

为了研究DC2000型钻石切工自动分析仪的测量精度,采用该仪器测量了标准的圆形明亮琢型CZ样品的切工比例。试验结果表明,DC2000型钻石切工自动分析仪达到了国际同类产品的测量精度,符合现代钻石切工分级的严格要求：腰棱直径和全深的最大偏差不超过0.01 mm,以百分数表示的台宽比、冠高比、腰厚比、亭深比和底尖比的最大偏差不大于±0.1%,冠角和亭角的最大偏差不大于±0.1o。DC2000型钻石切工自动分析仪可以为钻石切工分级和钻石加工过程的质量检测提供精确、可靠的数据。

Measurement Precision of DC2000 Diamond Proportion Analyzer

In order to study the measurement precision of DC2000 diamond proportion analyzer,the proportions of the standard round brilliant cut CZ samples are measured by the DC2000 diamond proportion analyzer.The experiment results show that the measurement precision of the DC2000 diamond proportion analyzer is almost the same as that of the international similar products,which accords with the modern diamond cut grading requirements.The requirements are that the maximum deviation of diameter and total depth is within 0.01 mm.The maximum deviation of the table,crown,girdle,pavilion and culet is within ±0.1%.The maximum deviation of angles,including crown angle and pavilion angle,is within ±0.1°.The DC2000 diamond proportion analyzer could provide accurate and reliable data for the diamond cut grading and quality testing during the cut process.
