    • In a turret mill of the kind in which a doughnut 20 moves with the tool head along a threaded vertical rod 1, a tube 4 is slidably mounted on the rod 1 between end plates 5 and 6 which support a turret 7. The turret 7 can be rotated to bring a series of axially adjustable stop elements 9 into position for contact with the doughnut 20, allowing downward movement of the tool head to be stopped in various quickly selectable positions. Such contact with a stop 9 causes the lower plate 6 to act on a head 3 secured to rod 1, which in turn operates a cutout 17 via a lever 16 to stop vertical feed of the tool head. Upward movement of the doughnut 20 engages the upper plate 5, which acts on the rod 1 via a plunger 25 and lever 26, causing the rod to move downwards. This again operates the cutout 17 to stop the tool head.
    • 在圆环20沿着螺纹垂直杆1与工具头一起移动的转塔铣刀中,管4可滑动地安装在支撑转塔7的端板5和6之间的杆1上。转塔7可以 旋转以将一系列可轴向调节的止动元件9置于与环形圈20接触的位置,允许待停止的工具头向下移动到各种快速可选位置。 与止动件9的这种接触使得下板6作用在固定到杆1上的头部3上,杆头1又经由杆16操作切口17,以停止工具头的垂直进给。 圆环20的向上运动接合上板5,上板5通过柱塞25和杆26作用在杆1上,导致杆向下移动。 这再次操作切口17以停止工具头。
