我们在实践中摸索到:要磨削表面粗糙度值较低的工件时,在不改变其它工艺条件的情况下,只用碳化錋精磨油石轻微修整砂轮,再磨削工件,其表面粗糙度值可降低1～2级。具体工艺方法如下:磨削分粗磨、精磨两道工序。粗磨时,先用金刚石笔修整砂轮,再进行磨削。(砂轮修整与磨削方法,不再赘述。)精磨前,再用金刚石笔修整一遍砂轮,以保证砂轮的几何精度。然后用碳化绷精磨油石按下述
We found in practice: To grind the workpiece with low surface roughness value, without changing the other process conditions, only use carbide grits fine grinding stone grinding, and then grinding the workpiece, the surface roughness Value can be reduced by 1 to 2 levels. The specific process is as follows: grinding points coarse grinding, grinding two processes. Rough grinding, the first diamond wheel dressing wheel, then grinding. (Wheel dressing and grinding methods, will not go into details.) Before grinding, and then diamond wheel dressing again grinding wheel to ensure the geometric accuracy of the wheel. Then use carbonized stretch grinding stone as follows
