Abstract: An apparatus for pointing twist drill bits includes a processing unit which has a rotary index plate on which are mounted a plurality, e.g., five, of drill bit holders which are circumferentially spaced apart at equal, e.g., 72-degree intervals, and a loading unit which has located adjacent to the index plate a rotary pedestal on which are mounted an equal number of transfer arms. Located around the periphery of the processing unit and loading unit are a plurality of processing stations and loading unit operation stations, respectively.
Abstract: A machine tool for processing workpieces of various shapes comprises three processing units each mounted on a carriage to move in three axes of coordinates and each being rotatable about a horizontal axis. Each processing unit carries a tool holder having tools and being turnable in two opposite directions. A workpiece is clamped in a workpiece holder so that it is immovable during operation and can be treated at least at three sides thereof simultaneously.
Abstract: A work turret is rotated by steps around a central axis with a first group of a multiplicity of clamping devices formed to clamp one side of a workpiece each facing a charging device for feeding in workpieces, and a second group of clamping devices on the side of the work turret averted from the charging device formed to clamp the machined end of a workpiece each. A gripper can be moved to and fro between the two sides of the work turret by which partially machined workpieces are removed from the clamping device of the first group and turned to be clamped in the clamping devices of the second group.
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: Manufacture of tapered thread nipples of cylindrical graphite sections in a production line with a rotary-cycle machine with stations and a turntable rotated at a predetermined period to move from one station to another. Prismatic guides radially connected to turntable to receive sections. A boring mill above the second station for drilling blind holes into the sections. Filing nozzles above the third station for filling the blind holes with binder. A tie-rod to remove the section from the fourth station. A turning machine for cutting free the binder filled holes.
Abstract: In an automatic transfer machine tool with circular supply movement for workpieces to be sequentially worked on in respectively separate working stations (I-V), a stepwise indexable workpiece holder (10) is journalled on a center post (8), the workpiece holder (10) having clamping devices (11) arranged thereon for the workpieces.

Abstract: Methods and apparatus are provided for handling and threading tubular products, including tubing, pipe, and casing for the petroleum production industry. In one embodiment of the present invention, an improved pipe handling system is utilized to transfer segments of pipe sequentially to a press, a threading machine, and quality control stations. The pipe handling system may include a plurality of plates driven by a common motor for raising and positioning the pipe, V-rollers for supporting and pre-positioning the pipe, a powered cart for transporting the pipe to the threading machine, and a plurality of steady rest assemblies for supporting a joint of rotating pipe during the threading operation.

Abstract: This invention relates to an automatic precision apparatus which includes an elongated rotatable central shaft concentric with and encased by a fixed outer cylinder. A rotary workpiece table is fixed to the central shaft adjacent one end of the central shaft, and a round tool holder table is fixed to the cylinder adjacent one end of the cylinder and disposed in spaced relationship with the rotary table and in parallel arrangement with the rotary table. A plurality of spaced tool holders are disposed around the round table, and a plurality of equally spaced workpiece holders are disposed on one surface of the rotary table facing the round table. Each tool holder is precisely aligned with a respective one of the workpiece holders and is alignable with every other one of the workpiece holders.
