    • In a coarse honing step in a section (101), a honing head (15) provided with coarse honing hones (17) is inserted into a cylinder bore (13) of a cylinder block (11), the honing head 15 is rotated while axially moving it, and the inner peripheral surface of the cylinder bore (13) is thereby ground. In the next idling step in a section (102), the cylinder block (11) is left as it is for (60) seconds to generate a springback (S). In a subsequent finishing honing step in a section (103), a honing head (21) provided with finishing honing hones (19) is inserted into the cylinder bore (13), the honing head (21) is rotated in a reverse direction to a rotational direction in the coarse honing step while axially moving it, and the inner peripheral surface of the cylinder bore (13) is thereby ground. Further, a coolant is supplied to the sections of the coarse honing step, the idling step, and the finishing honing step from coolant nozzles (23), (25), and (27), respectively, using a common coolant supply source (29).
    • 在部分(101)中的粗珩磨步骤中,将具有粗珩磨锤(17)的珩磨头(15)插入气缸体(11)的气缸孔(13)中,珩磨头15旋转同时 轴向移动,并且缸孔(13)的内周面由此被磨削。 在部分(102)的下一个空转步骤中,气缸体(11)保持原样(60秒)以产生回弹(S)。 在随后的整理珩磨步骤(103)中,将具有精加工珩磨锤(19)的珩磨头(21)插入缸孔(13)中,珩磨头(21)沿相反方向旋转 粗铣刨工序中的旋转方向同时轴向移动,并且缸膛(13)的内周面由此被研磨。 此外,使用共同的冷却剂供给源(29)将冷却剂分别从冷却剂喷嘴(23),(25)和(27)供给到粗珩磨步骤,怠速步骤和精加工步骤的部分, )。
