前言滚刀的加工精度与滚刀基准的加工精度。铲磨机床的传动精度、砂轮的修整精度以及刃磨精度皆有关。而其中以铲磨精度的影响为最大。滚刀铲磨精度与铲背工艺方法有密切关系。所以对滚刀铲磨精度的分析也涉及到铲背工艺带来的原始造型误差。高精度铲磨机床传动链传动精度的计算与其他具有内传动链的机床有所不同,只考虑机床传动链本身还不够,必须同时将滚刀刃磨及砂轮修整精度等因素一起考虑进去才比较全面。我们必须从铲磨机床传动链的设置、机床 Preface hob machining accuracy and hob-based machining accuracy. Shovel grinding machine drive precision, wheel dressing accuracy and sharpening accuracy are related. Among them, the impact of shovel grinding accuracy is the largest. Hob shovel grinding shovel back and precision methods are closely related. Therefore, the analysis of the precision hob hob grinding also involves the shovel back to bring the original modeling error. Precision grinding machine drive chain drive precision calculation with other machine with a transmission chain is different, only consider the machine tool drive chain itself is not enough, must be both hob grinding and grinding wheel dressing precision and other factors together into more comprehensive . We have to set the drive chain from shovel mill machine to machine
