    Abstract: A multi-cartridge cutting tool includes a body with a plurality of cartridge-receiving pockets, and a plurality of insert-receiving cartridges mounted to a respective pocket. A round cutting insert is mounted to each cartridge. The pockets are formed at predetermined distances from a central, longitudinal axis of the body to form a first group and a second group of cutting inserts such that the cutting edges of the first group of cutting inserts and the cutting edges of the second group of cutting inserts are located at different axial and radial distances from the central, longitudinal axis of the body to perform different machining operations. The cutting tool may be used as part of a railway wheel boring assembly.

    Abstract: There are provided a printed board drilling method and a printed board machining apparatus that are capable of improving machining quality, such positional accuracy of holes and true roundness of machined holes, and work efficiency by minimizing a runout of the tip of a drill. An extension of the drill extending out a spindle when the drill is held by the spindle is defined in advance per type or mode of use of each drill. One drill is selected among a plurality of drills corresponding to a shape of holes to be drilled in the printed board and the spindle is caused to hold the drill so that the selected drill extends out of the spindle by the extension corresponding to the selected drill. Then, the move of the spindle with respect to the printed board is controlled and the selected drill is rotationally driven by the spindle to drill the printed board.

    Abstract: An automatic tool changing apparatus incorporated in a drilling machine or the like comprises a plurality of collets, each for supporting and selectively grasping a tool holder mechanism. Each of the collets is slotted in its upper and central portions to divide the collet into a plurality of arcuate sections. The central portion of each collet is of generally truncated cone-shaped configuration, and rests in a generally truncated cone-shaped bore in a collet support block. A pneumatic piston arrangement is connected to the collets for selectively pulling the collets downwardly in their respective collet support blocks to move the generally arcuate sections of each collet radially inwardly to grasp a tool holder mechanism. Spring return means are provided for moving the collets into their normal positions wherein they will support, but will not grasp the tool holder mechanisms.

    Abstract translation: 结合在钻机等中的自动换刀装置包括多个夹头，每个夹头用于支撑和选择性地抓握工具夹持机构。 每个夹头在其上部和中部开槽，以将夹头分成多个弧形部分。 每个夹头的中心部分具有大致截头圆锥形构造，并且位于夹头支撑块中的大致截头圆锥形的孔中。 气动活塞装置连接到夹头，用于在它们各自的夹头支撑块中向下选择性地拉动夹头，以使每个夹头的大致弓形部分径向向内移动以抓住工具夹具机构。 提供弹簧复位装置用于将夹头移动到其正常位置，在这些位置它们将支撑，但不会抓住工具架机构。

    Abstract: A portal-type milling-boring machine has two columns disposed on opposite sides of a bed over which a workpiece-supporting table moves, a beam extending between the two columns over said bed. Working heads are carried by the columns and the beam for effecting different machining operations on a workpiece, and the columns are movable on respective transverse guides parallel to the axis of the beam to vary the effective width of the portal. This enables boring operations to be effected on the sides of the workpiece by the working heads carried by the columns. Suspensions are provided for transmitting the weight of the beam and the heads carried thereby to fixed auxiliary columns.
