    • A magnetically levitated high-speed spindle assembly (20) is provided for forming non-circular holes (22) in workpieces (24) or non-circular surfaces on pins. The non-circular holes (22) can be formed with dimensionally varying axial trajectories at high speeds and with great accuracy. This is accomplished by supporting a rotating spindle (26) between first (58) and second (60) magnetic bearing clusters and independently controlling these bearing clusters (58, 60) to move a shaping tool (32) at the end of the spindle (26) in a predetermined orbital path (B). A multiple input-multiple output control strategy is used to control spindle (26) movements in the X and Y axes. The tilt angle between the cutting edge (34) of the shaping tool (32) and the orbital path (B) is maintained perpendicular under this multiple input-multiple output control of the magnetic bearing clusters (58, 60) to further improve shaping precision and spindle (26) stability during high-speed operations.
    • 提供磁悬浮的高速主轴组件(20),用于在工件(24)或销上的非圆形表面上形成非圆形孔(22)。 非圆形孔(22)可以以高速和高精度形成尺寸变化的轴向轨迹。 这是通过在第一(58)和第二(60)磁性轴承簇之间支撑旋转主轴(26)来实现的,并且独立地控制这些轴承簇(58,60)以在主轴的端部移动成形工具(32) 26)在预定轨道(B)中。 多输入多输出控制策略用于控制X轴和Y轴上的主轴(26)运动。 成形工具(32)的切割刃(34)与轨道(B)之间的倾斜角度在磁轴承簇(58,60)的多输入多输出控制下保持垂直,以进一步提高成形精度 和主轴(26)在高速运行时的稳定性。

    • A toolholder apparatus is provided for holding a cutting tool adjacent a rotating workpiece. The apparatus includes a mounting block base and a mounting block body slidably supported on the base. A first adjustable connector connects the body to the base so that apposition of the body on the base can be adjusted in a first direction toward the workpiece. A center adjustment block slidably engages the body. A second adjustable connector connects the center adjustment block and the body so that a position of the center adjustment block on the body can be adjusted in a second direction transverse to the first direction and transverse to the rotational axis of the workpiece. A head is detachably mounted on the center. adjustment block. The head is removable from the center adjustment block by. sliding movement in a third direction transverse to both of the first and second directions. A cutting tool support is attached to the head so that the head and the cutting tool may be removed from the apparatus to replace the cutting tool and then the head and replacement cutting tool may be remounted on the apparatus.
    • 提供了一种夹持装置,用于将切割工具保持在与旋转工件相邻的位置。 该装置包括安装块基座和可滑动地支撑在基座上的安装块体。 第一可调节连接器将主体连接到基座,使得主体在基座上的安置可以朝向工件的第一方向进行调节。 中心调节块可滑动地接合身体。 第二可调连接器连接中心调节块和主体,使得中心调节块在主体上的位置可以在横向于第一方向并横向于工件的旋转轴线的第二方向上调节。 头部可拆卸地安装在中心。 调整块。 头部可从中央调节块移除。 在横向于第一和第二方向的第三方向上的滑动运动。 切割工具支撑件附接到头部,使得头部和切割工具可以从设备移除以更换切割工具,然后头部和替换切割工具可以重新安装在设备上。
