通过实验研究了砂轮转速的提高对磨削效果的影响。在外圆磨削试验中，砂轮转速由1300 m/min提高到3500 m/min。随着轮速的增加，单位时间内的地面体积增大，因此工作半径的实际减小量与理论减小量之比增大.磨削力（P）与砂轮速度（V）的关系为Poc（1/V）0.791.47。砂轮粒度越小，该公式的指数值越大.提高砂轮转速的另一个结果是通过减小切屑厚度来提高工件的表面光洁度.较高的轮速对高钒高速钢等耐热钢的影响要小于碳钢.在高速磨削时，必须将倾斜的金属片固定在砂轮上，以使旋转砂轮上的气流偏转，从而防止冷却剂渗透到磨削区域中。
The influence of the increase of wheel speed on the grinding results has been studied experi-mentally. In this cylindrical grinding tests, the wheel speed was increased up to 3500m/min from 1300m/min. The following results are obtained : 1. As the wheel speed is increased, the ground volume per unit time increases and so the practical reduction of work radius versus the theoretical reduction of work radius increases.2. The relation between the grinding force (P) and the wheel speed (V) is Poc (1/V) 0.791.47. And as the grain size of wheel is smaller, the value of the index of this formula is larger.3. The other result of higher wheel speed is the improvement of the surface finishing of the workpiece by decreasing the thickness of chip.4. The influence of the higher wheel speed is smaller to the heat resisting steel as like the high vanadium high speed steel than to the carbon steel.5. At the high speed grinding, an inclined metal sheet must be fixed against the wheel in order to deflect the air-flow on the rotating grinding wheel which prevents the coolants from penetrating into the grinding zone.
