1·Through analyzing the characteristics of the part, according to drilling hole on the conical surface, designed the special clamping tool.
通过对零件的工艺性分析，针对零件要在锥面上钻孔的特点所设计的专用夹具。
2·The ideal rock sample is the conical surface rock sample that can joint crest of teeth in single row drilling experiment.
在单齿圈破岩试验中，理想的岩样是与牙齿齿顶线相贴合的锥面岩样。
3·However, because of lacking high efficiency and high precision for the measurement of craters on the conical surface rock, the traditional single row drilling experiment is carried out on planar rock.
由于缺乏对锥面岩石破碎坑的有效的、高精度的测量手段，所以传统的单齿圈试验都是针对平面岩样进行的。
4·In order to improve bearing capacity and compactness of the roll system, a method of double circular arc conical surface transition curve for roll neck is put forward.
为了提高轧辊的承载能力和辊系结构的紧凑性，提出了对辊颈双圆弧锥面过渡曲线的优化设计方法。
