self sharpening

The results show that, the selected grinding wheel is well self-sharpening during the test, and the surface roughness does not exceed the bounds.

结果表明，所选择砂轮具有较好的自锐性，在试验过程中，表面粗糙度没有出现超差的情况。

Resin bonded silicon carbide grinding block during the grinding process, high grinding efficiency, good self sharpening abrasive tool, workpiece surface is not easy to burn and polishing performance and good processing properties, it can be widely applied in the field of material surface processing.

树脂结合剂碳化硅磨块在磨削过程中磨削效率高、磨具自锐性好、被加工工件表面不容易烧伤和抛光性能好等加工特性，因此在材料表面加工领域得以广泛应用。

Abrasive grain up only 30 % weight; its self-sharpening action is weaker, resulting in lower grinding efficiency.

磨粒只占总重的30%; 其自锐性弱, 因而磨削效率很低.

Through grinding experiments, the grinding performances of resin bond grinding wheels made with self-sharpening diamond ( CSD) was studied.

本文通过对比磨削试验，研究了自锐性金刚石（CSD）树脂砂轮的磨削性能。

Bao Jianfeng self-sharpening out, plum blossom incense come from the bitter cold.

宝剑锋自磨砺出, 梅花香自苦寒来.
