If the undeformed chip thickness is reduced, the effect of the top part of the abrasive grain will increase. 当未变形切屑厚度减小时，磨粒顶端钝圆的影响增大；
The bond is mainly intenbed for hording the abrasive grain together so that the bonded wheels have got definite shapes and necessary strength. 结合剂的主要作用是将磨粒固结在一起,使之具有一定的形状和强度。
Under the condition of boundary lubrication,adhere wear mechanism and abrasive grain wear mechanism do the business at the same time. 在边界润滑条件下
The first principal normal stresses can lead to grinding crack which generates behind the abrasive grain in the plane perpendicular to grain motion. 在磨粒后方，受第一主应力的作用，产生垂直磨削方向的磨削裂纹。
For the effects of test conditions, the volume wear value increased with the sliding velocity and the abrasive grain size except for the sliding velocity of 1.68 m/s and 3.02 m/s. 在试验范围内，对于同一种尺寸的磨料，随着滑动速度的增加，目标包的体积磨损量增加； 当滑动速度为1.
