    摘要： A machine tool has a work table which defines a working surface and has a cutting tool which is attached to and movable with respect to the work table. The position of the cutting tool with respect to the working surface is controlled by a mechanism which elevates the cutting tool with respect to the working surface and angulates the cutting tool with respect to the working surface. The cutting tool is mounted to a support plate which is pivotably attached to the work table. The elevating mechanism includes a threaded rod and a nut which engages a pivoting link. The pivoting link also engages the cutting tool. Rotation of the threaded rod pivots the link which in turn raises and lowers the cutting tool. A spring biases the cutting tool towards its lower position to remove play between the components. The angulating mechanism includes a lever, two cams and a locking rod. Rotation of the lever moves the locking rod longitudinally due to the action between the two cams. The longitudinal movement of the rod compresses the support plate between the work table and a bracket to maintain the position of the support plate with respect to the work table. Also included is an integral arbor wrench which is accessible when the throat plate is removed to lock the arbor to facilitate tool changing. The wrench is designed to not allow reassembling of the throat plate when the wrench is in engagement with the arbor shaft.

    摘要翻译： 机床具有定义工作表面的工作台，并具有连接到工作台并可相对于工作台移动的切削工具。 切割工具相对于工作表面的位置由一个使切割工具相对于工作表面升高并使切割工具相对于工作表面成角度的机构来控制。 切割工具安装到可枢转地附接到工作台的支撑板上。 升降机构包括螺杆和与枢转连杆啮合的螺母。 枢转连杆还与切割工具接合。 螺纹杆的旋转使连杆枢转，该连杆又升高并降低切削工具。 弹簧将切割工具偏压到其下部位置以去除部件之间的间隙。 成角机构包括一个杠杆，两个凸轮和一个锁定杆。 杠杆的旋转由于两个凸轮之间的作用而纵向移动锁定杆。 杆的纵向移动将支撑板压在工作台和支架之间，以保持支撑板相对于工作台的位置。 还包括一个整体的心轴扳手，当拆除喉板以锁定心轴以便于更换刀具时可以进入。 扳手被设计成当扳手与心轴轴接合时不允许重新组装喉板。
