查询词典 grindings

Surface roughness and geometry topography have very obvious difference between ordinary and ultraprecision grindings. Surface roughness of ultrapreciscon grinding will decrease with abrasive size and grinding depth decrease, surface veining owing to plastic deformation is very clear.

超精密磨削和普通磨削的表面粗糙度和几何形貌存在明显的差异，超精密磨削的表面粗糙度随着金刚石砂轮磨粒尺寸和磨削深度的减小而减小，表面由于塑性变形形成的纹理比较明显。
