全苏安装和特种建筑工程科学研究所基辅分所研究了建筑安装工程条件下在轻便(主要是摆动型)设备和手动磨机上使用纤维补强型切割砂轮时提高砂轮耐磨性的可能性。因为切割砂轮的切削刃部分受到周期性热负荷作用(当切削刃部分离开接触区后便发生急剧冷却),所以,测定的不是砂轮结合剂的瞬时温度,而是其旋转期间的平均温度。同时
The Kiev branch of the Institute of Installation and Special Construction Engineering at All-Su has studied the possibility of improving the abrasion resistance of grinding wheels when using fiber-reinforced cutting wheels on lightweight (mainly oscillating) equipment and manual mills under construction and installation conditions. Because the cutting edge portion of the cutting wheel is subjected to a cyclical thermal load (sharp cooling occurs when the cutting edge portion leaves the contact area), it is not the instantaneous temperature of the wheel bond, but the average temperature during rotation. Simultaneously
