我厂在旧的M120W万能外圆磨床上,采用砂轮磨削修正的简便方法,能使工件表面达到镜面的效果。这种磨削只需工件经过一般磨削达到▽▽▽8后,利用磨削修正的平坦砂轮、充足而清洁的切削液、较小的磨削用量,就可直接在磨床进行镜面磨削。目前对T7A材料、硬度为R_c50～60的工件,磨外圆的平均表面不平度能达到0.08～0.1微米,光洁度▽▽▽▽13;磨内圆平均表面不平度0.18～0.23微米,光洁度▽▽▽▽2;棱圆度都≤0.4微米,表面无划伤。镜面的反射状态如图1、2。
I plant in the old M120W Universal Cylindrical Grinder, the use of grinding wheel to amend the easy way to make the workpiece surface to achieve the mirror effect. This kind of grinding only needs the normal grinding of the workpiece to reach ▽ ▽ ▽ 8, the use of grinding correction of the flat wheel, adequate and clean cutting fluid, a smaller amount of grinding, you can directly grind mirror grinding. Currently T7A material, the hardness of the workpiece R_c50 ~ 60, the average surface roughness of the grinding wheel can reach 0.08 ~ 0.1 microns, finish ▽ ▽ ▽ ▽ 13; mill inner circle average surface roughness of 0.18 ~ 0.23 microns, finish ▽ ▽ ▽ ▽ 2; Degree of roundness ≤ 0.4 microns, the surface without scratches. Reflective mirror state shown in Figure 1,2.
