Abstract: A vertical machining center includes a machining table on which a first pallet is placed and which moves in an X axis direction. A spindle head includes a spindle and moves in a Z axis direction. A rotary pallet exchanger exchanges the first pallet with a second pallet in a setup area. In a pallet rotational movement area, the first and second pallets are rotated. An oil pan is below the second pallet in the setup area, accommodates a part of the pallet rotational movement area, and includes a cutout portion. Space exposed to the cutout portion forms a cutout area. A door partitions a machining area from the setup area. An amount of offset in the X axis direction from the axial center of the spindle to the rotational center of the pallet exchanger is equal to or less than a width of the first pallet.

Abstract: A machining unit, typically for wood panels, features a work table afforded by a body of prismatic geometry having at least two faces and rotatable about an axis which is also its instantaneous center, in such a way as to establish at least two movable and tiltable work surfaces; the prismatic body is carried within a frame encompassing the tool and combining with the two faces to create respective independent work areas, one in which panels are fed to and from the unit, the other coinciding with a station at which machining takes place, and where the waste and chips generated by machining are cleared from the table and the work. The prismatic body also functions as the main barrier separating two work environments, the one an open external space occupied by the operator, the other an enclosure disallowing access to the operator while machining is in progress.

Abstract: In an automatic bar and wire pointing machine, workpiece-feeding means comprises a carrier having two feeding wheels (38,40) mounted on a driving shaft (20). Each wheel comprises a circular pitch plate (42) providing four sets of six notches (N1, N2, N3, N4) spaced uniformly around its periphery; the notches form semi-circular recesses (R1, R2, R3, R4) of different diameters to accommodate different sizes of workpiece, and the recesses are all centered on a common pitch circle (P) of the pitch plate. The wheel comprises also a picker plate (44) comprising six lobes (66) which are spaced uniformly about the axis of the wheel and form radially-projecting edges (68) positioned adjacent to the notches of any selected one of the four sets of notches.

Abstract: A machine has an intermittently rotating table for holding parts to be worked on or assembled. Operating units (20, 21, 25) are actuable either simultaneously for all units or groups of units, or independently of one another. The operating units can be mounted vertically over or under the table and also laterally and can receive the rotary movement of a central wheel or independent motors. According to a preferred embodiment, the control of the feed is effected by the central shaft (4). During a work cycle, this shaft makes a vertical movement and transmits that movement to the operating units (20, 21) by radial linear cams (16, 17, etc.), i.e., feed and return occur during a single movement of the shaft (4), for example, downward. During idle time, i.e.

Abstract: A table (1) revolving intermittently and carrying on its periphery piece-holder grips, has central openings (11), which make possible the discharge of working shavings and wastes at the center of the table itself (arrow 12) and not at the periphery (arrows 7, 7') as now is done. This makes possible direct discharge of the working shavings and wastes in the collection container underneath and avoids clogging and stopping of the machine for cleaning which requires the presence of additional labor and limits production. Nozzles (13, 13') direct fluid radially inwardly to assist in this central discharge of shavings and wastes.

Abstract: A handle-cutting device comprises a conveyor in the form of a horizontal table arranged to be rotated step-by-step to bring handle holders in turn to a handle-cutting station where the handle is lightly clamped. While the holder is stationary at the handle-cutting station, a rapidly rotating cutter (for example, rotating at 3,000 r.p.m.) having a contoured blade representing the profile of the wall of a cup bowl to which the handle is to be attached is progressively advanced towards the holder to remove surplus clay in thin slices from the handle. The blade is unconfined along those parts of its length which effect the cutting, being mounted on spaced apart supporting portions of a carrier, so that the small pieces of clay sliced away by the blade can escape from the cutter. The device ensures a high degree of conformity of the attaching surface of the handle to its intended configuration.

Abstract: A method and apparatus for smoothing local unevenness from the surface of bar material, such as anode bars, consisting of clamping the bar rigidly against a supporting frame and moving a smoothing device along the bar, said smoothing device maintained in continued contact with the bar by means of rollers pushing against opposed parallel faces of the bar. The rollers allow the smoothing device to move according to the general contour of the bar, so that only local unevenness is removed, and excessive smoothing due to curvature in the overall bar length is eliminated.

Abstract: A transfer machine of the type in which workpieces are successively transferred through a series of work stations on either side of the line of movement of the workpieces with work heads located at each station to perform various operations on the workpieces. The disclosed transfer machine consists of one or more transfer machine module units, each module including a prismatic base having upwardly directed sides upon which are mounted a series of oppositely directed heads and the workpiece transfer system mounted to the base and extending between the work heads to convey the workpieces up and down the base sides. The resulting vertical spacing of the work heads from one another enables closer spacing of the work heads by enabling access to the tooling through the space through which the workpieces are transferred, while reducing the floor space required for the machine. Also, chips formed during machining operations fall away so as not to accumulate at the machining station.
