在六角車床及自动車床上加工圆棒料時对夾紧棒料的彈簧卡头(圖1)最基本技朮要求之一是保証棒料对主軸旋轉中心的相对位置准确度(卽棒料对主軸的旋轉中心綫应保持最大程度的同心度),因为同心度偏差的大小直接影响加工裕量的均勻性,若加工裕量不均勻,便会引起工件几何形狀的誤差,机床系統的振动及減少切削刀具耐用度。
One of the most basic technical requirements for the spring chuck (Fig. 1) of the clamping bar when machining round bars on a hexagonal lathe and automatic lathe is to ensure the relative position accuracy of the bar stock to the spindle rotation center (卽 bar to spindle Of the center of rotation should maintain the maximum degree of concentricity), because the size of the concentricity deviation directly affect the uniformity of the processing margin, if the processing margin is not uniform, it will cause the workpiece geometry error, vibration and reduce machine tool system Cutting tool durability.
