砂轮表面几何形状和表面粗糙度是决定砂轮磨削性能的重要因素。在磨削过程中,由于磨削力和磨削温度等的作用,砂轮工作表面上的磨粒会逐渐地磨钝;同时,由于磨粒不均匀磨损和脱落,使砂轮工作表面失去正确的几何形状;磨削过程中产生的细小切屑还会粘附到工作磨粒的切削刃上或堵塞到砂轮工作表面的空隙中。所有这些 Wheel surface geometry and surface roughness is an important factor in determining wheel grinding performance. In the process of grinding, due to the grinding force and grinding temperature, etc., the abrasive particles on the working surface of the grinding wheel will gradually blunt; at the same time, the working surface of the grinding wheel loses the correct geometry due to the uneven wear and shedding of the abrasive particles Shape; small chips generated during the grinding process will also adhere to the cutting edge of the working abrasive or clogged into the working surface of the wheel gap. all of these
