摘要： A portable milling tool for milling pipes, tubes, cylinders, and the like has a collet (41, 140) at one end thereof for securing and centering the tool to the work piece. An adjustable in-line rod (39,139) connects the collet (41,140) to the tool and permits the collet to secure or release the work piece. An in-line shaft (12, 112) moves the tool into or out of engagement with the work piece. The tool is of compact design allowing it to be used in on-site situations wherein tool size is a problem.

摘要： A portable gas operated rotary tool (10) is provided for milling a surface on the end of a cylindrical workpiece (11). The tool has a motor (20) powered by a pressurised gas, such as compressed air. The motor directly drives a rotary milling head (60) which is axially aligned with the axis of rotation of the motor. The motor has a stator chamber (25) which houses a rotor (35) having radial slots (42). Vanes (43) are journalled within said slots for radial movement within the slot and define progressively expanding cavities. The milling head (60) has a central bore (62) for mounting on an arbor (55) of the motor. The milling head includes blades (68, 69, 70) for milling a frustoconical surface on the workpiece and a non-locking pilot tube (64) to align the tool with the longitudinal axis of the workpiece. A novel air motor design is also disclosed that provides very high rotary speeds using standard air system pressure, very high horsepower, a low polar amount of inertial and a low torque.
摘要翻译：提供了便携式气体旋转工具（10），用于铣削圆柱形工件（11）的端部上的表面。该工具具有由加压气体（例如压缩空气）供电的马达（20）。马达直接驱动旋转铣头（60），其与马达的旋转轴线轴向对准。电动机具有容纳具有径向槽（42）的转子（35）的定子室（25）。叶片（43）被轴颈安装在所述槽内，用于在槽内径向移动并且限定逐渐扩大的空腔。铣头（60）具有用于安装在马达的心轴（55）上的中心孔（62）。铣头包括用于铣削工件上的截头圆锥形表面的刀片（68,69,70）和用于将工具与工件的纵向轴线对准的非锁定先导管（64）。还公开了一种新颖的空气马达设计，其使用标准空气系统压力，非常高的马力，低极性的惯性和低扭矩提供非常高的旋转速度。
