磨削是获得高精度和细的表面粗糙度的重要方法之一。磨削是依赖于砂轮表面上的微刃进行切削加工的,而砂轮表面上的微刃同其他刀具的切削刃一样工作一段时间后就要被磨损,即刃口钝化、气孔堵塞、砂轮失去切削能力、廓形失真,使工件表面粗糙度增大。工件精度下降、产生螺旋形波纹和烧伤等。为了恢复砂轮的切削能力必须对砂轮进行修整,去掉堵塞层,显露出新磨粒,形成足够多的微刃。现在, Grinding is one of the important ways to achieve high precision and fine surface roughness. Grinding is dependent on the micro-edge grinding wheel surface machining, and the micro-edge grinding wheel surface with the cutting edge of other tools like to work after a period of time to be worn, that the blade passivation, stomata blocked, the wheel loses Cutting capacity, contour distortion, the workpiece surface roughness increases. Workpiece accuracy decreased, resulting in spiral ripples and burns. In order to restore the cutting ability of the grinding wheel, the grinding wheel must be trimmed, the blockage layer removed, new abrasive grains revealed, and a sufficient number of micro-edged blades formed. just now,
