    • A high speed system (50) for drilling of very small holes in workpieces (137) such as printed circuit boards. The X-Y positioning system includes air bearings (120) to provide lift between the stationary guide beams (60, 62), the cross beam (65), and the top table (70), and further includes a vacuum preloading apparatus (128). The top table (70) is a light honeycomb structure (71, 72, 73), whose effective rigidity is virtually that of the guide beams (60, 62) due to the vacuum preloading. The system (50) includes a conventional spindle (85) and a high speed spindle (81). The high speed spindle (81) includes a stationary body (156) carrying the stator (195, 196) of the drive motor. Only the spindle rotor (160) is translated along the Z axis to perform drilling movements. The rotor (160) is supported within the body (156) by rotary and linear air bearings (179, 187), and is axially driven by a linear motor (210, 220). A tool changer (95) loaded by clips (350) carrying the drilling bits (400) is mounted on the top work table (70). A vacuum hold-down apparatus (140) secures the workpieces (137) to a drilling station.
    • 一种高速系统(50),用于在诸如印刷电路板的工件(137)上钻出非常小的孔。 X-Y定位系统包括空气轴承(120),以在固定导向梁(60,62),横梁(65)和顶部工作台(70)之间提供升降,并且还包括真空预加载装置(128)。 顶台(70)是轻质蜂窝结构(71,72,73),由于真空预加载,其有效刚性实际上是导向梁(60,62)的有效刚度。 系统(50)包括传统的主轴(85)和高速主轴(81)。 高速主轴(81)包括承载驱动马达的定子(195,196)的静止主体(156)。 只有主轴转子(160)沿Z轴平移进行钻孔运动。 转子160由旋转线性空气轴承179和线性空气轴承187支撑在主体156内,并且由线性马达210,220轴向地驱动。 由承载钻头(400)的夹子(350)加载的工具更换器(95)安装在顶部工作台(70)上。 真空压紧装置(140)将工件(137)固定在钻孔台上。
