磨削时所用的冷却液喷嘴,其喷射出的冷却液被高速空气层流所阻挡,因此不能清除砂轮表面的磨屑和附着物,从而降低了磨削效率。现采用一种利用砂轮旋转速度来提高冷却液速度,而不是用通常的提高冷却液压力的方法来清除砂轮表面的磨屑。如图所示,利用一个带切槽的瓦形冷却罩,罩到砂轮约70°的弧面,它到砂轮表面的距离保持在0.8～1.5毫米之间,冷却液分成三股
Grinding coolant nozzle used, the jet of coolant is blocked by the high-speed air laminar flow, it can not remove the grinding wheel debris and attachments, thus reducing the grinding efficiency. Instead of using the usual method of increasing the pressure of the coolant to remove abrasive debris on the wheel surface, a method of utilizing the wheel rotation speed to increase the coolant velocity is used. As shown in the figure, a groove-shaped shroud is used to cover the cambered surface of the grinding wheel about 70 °. The distance from the grinding wheel surface to the surface of the grinding wheel is kept between 0.8 and 1.5 mm. The cooling liquid is divided into three strands
