Provided is a machine tool configured for machining by removing material from an object defining a machining surface and including a removal tool of material from the object and driving means configured to be placed directly in contact with the machining surface and to move said machine tool and, thus, the removal tool, with respect to the object.

A portable device to drill holes has a platform. A plurality of wheel sets is coupled to the platform. A drive system is used for driving the plurality of wheels. An attachment mechanism is positioned on an underside of the platform for securing the device to a surface. A control board is used for controlling the operation of the device. A drill spindle assembly is coupled to the platform. A drill feed assembly is coupled to the drill spindle assembly for raising and lowering the drill spindle assembly. A plurality of sensors are operable to sense one or more magnets disposed below the surface. A drive table is used for positioning the drill spindle assembly in an XY plane based on an output of said plurality of sensors.

A modular two-part welding and processing platform is described. A cart section is capable of rotating around objects such as pipes and cylinders, or of linear travel along plates or the like. This cart section reversibly couples to a processing section supplied for instance with welding apparatus, painting apparatus, cleaning means, analysis means or the like. By means of this two-part device, work pieces can be cleaned, welded, and inspected quickly and accurately. Special marks may be provided on the work piece which in conjunction with sensors and motoring means on the cart, allow for precise positioning of the process head with respect to the work.

A method and apparatus for installing a fastener in a surface of a structure. A crawler robot may comprise a first movement system and a second movement system. The first movement system may be configured to move the crawler robot and a track system along the surface. The second movement system may be configured to move the crawler robot along the track system on the surface.

A magnetic base for supporting a tool having a work piece engagement component relative to a ferromagnetic body, comprising: at least two magnet units having a working face, each unit adapted to be magnetically attached to the ferromagnetic body; and a support structure coupled to the at least two magnet units and including a mounting structure adapted to secure the tool to the support structure, the support structure having a window in or a cut-out extending into an about centric location of the support structure such that the work piece engagement component of the tool may extend from a first side of the support structure to engage the ferromagnetic body located proximate a second side of the support structure, the second side being opposite the first side, the at least two magnet units being positionable so that they can fit onto a flat surface or a curved surface.

An apparatus for precision shaving is provided. In one embodiment, the apparatus includes an endmill cutter, a base frame, and a motor adjacent to the base frame and having a shaft on one end. A coupler is positioned between the shaft and the endmill cutter. A positioning slide is housed within the base frame and a coupler frame and a first gear are fastened to the positioning slide. A second gear is adjacent to the first gear, the second gear having a set of first teeth and a set of second teeth positioned opposite the set of first teeth. The set of first teeth and the set of second teeth are separated by a gap.

According to one implementation, a drilling machine includes at least one drilling structure, a travelling machine, a reader and a controlling device such as a controlling circuit. The at least one drilling structure drills an object to be drilled. The travelling machine positions the at least one drilling structure in a travelling direction of the travelling machine by travelling in a direction different from a drilling direction. The reader reads information recorded on at least one integrated circuit tag attached to at least one drilling plate attached to the object to be drilled. The controlling device controls the travelling machine based on the information read by the reader.

The invention relates to a device (22) for calibrating an underfloor wheelset lathe (3) without a calibration wheelset, comprising; a motor (23) with a rotational axis (D), a friction roller (24), and a measuring bridge (18), wherein the friction roller (24) is connected p a driveshaft of the motor (23). The aim of the invention is to allow a simpler calibration without a calibration wheelset. This is achieved in that the friction roller (24) has an approximately cylindrical frictional surface with a defined nominal diameter. The invention additionally relates to an underfloor wheelset lathe (3) comprising such a device (22) and to a method for calibrating an underfloor wheelset lathe (3).
