    • A machine tool assembly, and particularly a spindle unit therefor, is provided wherein the spindle unit is relatively small and is designed to run at rotary speeds of between 30,000 rpm's and 40,000 rpm's utilizing hydrodynamic bearings for the spindle shaft. The hydrodynamic bearings are effective to take increased loads versus similarly sized conventional metal-to-metal contacting bearings to provide a very stiff machining system even with the higher loads generated by the increased rotary operating speeds for high speed machining contemplated for the spindle unit herein. The bearings are also designed to use a water-based fluid which is compatible with the cutting fluid. Non-contacting fluid barrier seals limit and control the amount of bearing fluid leaked to the cutting fluid. Due to the compatible nature of the two fluids, small fluid leakage from the bearings will not hurt the cutting fluid. The cutting fluid circulated at an ambient inlet temperature, e.g. , 70°F., and leaves at a higher discharge temperature, e.g. , 120°F., to cool the spindle and bearings. A cutting tool mounting adapter is provided which is attached to the spindle shaft by expansion of the shaft socket with high pressure hydraulics for shrink fitting of the socket onto the adapter when the hydraulics are removed so that the traditional highly tapered sockets and tool supports are not necessary, keeping the size of the front of the spindle small. The adapter also allows a commercially available tool to be employed in the high speed spindle unit herein.

    • An integrated spindle and motor unit includes a housing containing both the spindle shaft and motor with hydrostatic bearings around the front and rear of the spindle shaft. The hydrostatic bearings utilize high pressure oil, preferably in the range of 1,200-1,500 psi and provide good load bearing capacity and increased stiffness for improved cutting accuracy when cutting within the full range of cutting speeds. The present spindle unit is designed to be run at high speeds. The front and rear hydrostatic bearing pads are closely axially spaced along the spindle shaft so that the dynamic stiffness of the spindle is increased to avoid resonant vibrations even at high speed operation thereof. The spindle unit incorporates a sealing system utilizing a series of non-contacting seals including a labyrinth seal and aerostatic floating ring seals which keeps bearing oil in the spindle. The aerostatic ring seals have air restrictor openings therein to create an aerostatic air film that also keeps the rings concentric with the spindle shaft even though the spindle shaft is tilted in a nutator. A permanent magnet (PM) motor is integrated with the spindle with the rotor of the motor on the spindle shaft carrying the permanent magnets rotating within the stator of the motor which is attached in the spindle housing. The PM motor herein can provide high levels of power, e.g., at least 100 hp at the tool head, even in the short span provided by the short spindle shaft. At high speeds the bearing fluid may be pumped by viscous pumping from the radial bearing pockets. To counter such viscous pumping, small low pressure pockets are provided with low pressure oil to fill the high pressure pockets with oil.

    • In a cutting machine having an octahedral framework (12), a cutting tool (14) is carried by a servostrut support (15) having a platform (16) mounted on extendable and retractable struts (18). In order to reduce deflections and to limit transfer of bending moments, from the servostrut support (39) to the other connected support sections (40) of the framework (12), the six struts (18) are mounted at pivot mounts such as ball joints (36) in a triangular support (39). Three of the pivotal mounts are positioned in a first triangle and in corners of the triangle support (39) and the other three struts are positioned in a second larger triangle in the triangular support (39). The nominal axis of rotation of spindle drive (27) for the cutting tool may be either about a nominal horizontal axis, a nominal vertical axis or a nominal 45° axis. Several frameworks may be arranged to define a hollow tunnel (80) with platforms projecting their cutting tools (14) from opposite sides of the transfer tunnel (80).
    • 在具有八面体框架（12）的切割机，切割工具（14）由支撑servostrut（15），其具有一个平台（16）中进行安装在可伸缩支柱（18）。 为了减少偏转和限制弯曲力矩的传递，从servostrut支撑件（39）连接到框架（12）的其它连接的支撑部分（40），六个支柱（18）被安装在枢转固定件：如球 接头（36）中的三角形支撑件（39）。 枢轴安装件中的三个定位在第一三角形和在三角形支撑件（39）和其他三个支柱的角部在三角形支撑（39）的第二较大三角形被定位。 主轴驱动器（27），用于切削工具的旋转轴线标称可以是围绕标称水平轴线，名义上垂直轴或标称45°轴线。 几个框架可以被布置为与平台从转移隧道（80）的对置两侧凸出他们的切削刀具（14）限定一个中空隧道（80）。
