摘要： A spindle device with a built-in motor comprises a casing, a working spindle having a large radius portion formed with a bore and a small radius portion extending from the large radius portion, the large radius portion being housed in the casing, and the small radius portion protruding from the casing and having a working tool mounted thereon, a cylindrical motor rotor attached to an inner surface of the large radius portion of the working spindle, a fixed shaft provided in the casing and loosely inserted into the motor rotor, and a motor stator mounted on an outer surface of the fixed shaft opposed to the motor rotor. The casing is formed with an air passageway having a plurality of injection nozzles which are open at an inner surface of the casing opposed to an outer surface of the large radius portion of the working spindle. The working spindle that is rotating is supported by supplying air consecutively from the injection nozzles to a narrow space formed between the inner surface of the casing and the outer surface of the large radius portion of the working spindle.
摘要翻译：具有内置马达的主轴装置包括壳体，具有形成有孔的大半径部分的工作主轴和从大半径部分延伸的小半径部分，大半径部分容纳在壳体中，并且小的从壳体突出并具有安装在其上的工作工具的半径部分，安装在工作主轴的大半径部分的内表面上的圆柱形电机转子，设置在壳体中并松动地插入到电动机转子中的固定轴，电动机定子安装在与电动机转子相对的固定轴的外表面上。壳体形成有具有多个注射喷嘴的空气通道，该喷嘴在与壳体的与工作主轴的大半径部分的外表面相对的内表面处开口。正在旋转的工作主轴通过从注射喷嘴连续供给到壳体的内表面和工作主轴的大半径部分的外表面之间的狭窄空间来支撑。

摘要： A machining center in which the moment exerted on a support base and support table during a machining operation is remarkably reduced. The machining apparatus includes a pair of guide rails extending in the longitudinal direction relative to the workpiece upon which the machining head is slidably supported either directly or via a table. The rear one of this pair of guide rails is made higher than the other guide rail, thereby reducing the reaction forces exerted upon the upper surfaces of the guide rails, and hence the moment exerted on the supporting base.
摘要翻译：在加工操作期间施加在支撑基座和支撑台上的力矩显着减小的加工中心。该加工装置包括一对导轨，其相对于工件在纵向方向上延伸，加工头可以直接或经由工作台滑动支撑在该工件上。这对导轨中的后一个导轨比另一个导轨更高，从而减小了施加在导轨上表面上的反作用力，从而减小了施加在支撑基座上的力矩。
