车床在大修后试切时,常常在工件外圆上出现规律性的波纹,这种波纹的特点是纹与纹的距离都一样,波纹横断面的外廓形状多数是下凹的。严重时可以用手摸出。这种现象严重的影响修理质量。 通过长期实践,我们了解到,出现“规律性波纹”的主要原因是走刀量不稳(包括溜板的爬行及光杠 Lathe after overhauling the trial cut, often appear on the outer circumference of the workpiece regular ripples, the characteristics of this ripple is the same as the distance between the pattern and the corrugated cross-sectional shape of the majority of the outer concave. Serious when you can touch out. This phenomenon seriously affects the quality of repair. Through long-term practice, we understand that the main reason for the appearance of “regular ripples” is that the amount of cutting instability (including the slide crawl and light bar
