文中介绍了在特制的砂轮电动旋转机构中,砂轮锋锐度的测量试验。通过测量因砂轮与一聚四氟乙烯轮摩擦而引起的电功率损失,可以测得摩擦系数,藉此来评价随机分布在砂轮表面的磨粒切刃的锋锐度。
This paper introduces the measurement experiment of the wheel sharpness in the special grinding wheel electric rotary mechanism. The coefficient of friction can be measured by measuring the loss of electrical power due to friction between the wheel and a Teflon wheel to evaluate the sharpness of the edge of the abrasive grains randomly distributed on the wheel surface.
