A measuring device is provided which, in order to measure measured variables of an object being measured, can be placed on a surface of the object being measured. The surface supports the measuring device. The measuring device comprises at least three projecting contact surfaces, the center points of which are distributed substantially uniformly along a circle. The projecting contact surfaces, when the measuring device is placed on the surface of an object being measured, lie against the surface and are supported by the surface. A first of the contact surfaces comprises a temperature sensor for measuring the surface temperature of the object being measured, while a second and a third of the contact surfaces are provided to measure respective other measured variables.

Pipe machining apparatuses and bearing assemblies are provided. In one aspect, a pipe machining apparatus includes a frame, a tool carrier, a first roller bearing and a second roller bearing. The tool carrier is coupled to and movable relative to the frame and defines a race therein. The first roller bearing includes a first shaft and a first roller rotatably coupled to the first shaft. The first roller is at least partially positioned in the race and is rotatable about a first roller bearing axis adapted to remain substantially fixed relative to the frame. The second roller bearing includes a second shaft and a second roller rotatably coupled to the second shaft. The second roller is at least partially positioned in the race and is rotatable about a second roller bearing axis. The second roller bearing is adjustable to move the second roller bearing axis relative to the frame.

Embodiments of the present disclosure include portable milling tools and methods for milling components. In an embodiment, a portable milling tool can be provided for a component including a plurality of dovetail slots therein, each of the plurality of dovetail slots being oriented substantially axially relative to a rotation axis of the component. The portable milling tool can include: a mounting plate configured to engage the component; a tool-aligning member slidably coupled to the mounting plate and extending along a chordal axis relative to the rotation axis of the component; and a milling head extending axially from the tool-aligning member to a selected one of the plurality of dovetail slots, such that sliding movement of the tool-aligning member relative to the mounting plate moves the milling head along the chordal axis to contact a selected one of the plurality of dovetail slots.

A fixturing device for attaching attached to a work piece and methods of attaching the fixturing device to the work piece. The device may include a body, a base, and an extension. The extension may extend outward from the body and is sized to initially be positioned within an opening in the work piece. The extension may be expandable in size to engage with a backside of the work piece at the opening to secure the device to the work piece. The device further includes an interface for receiving to a tool that performs an operation on the work piece.

A milling device is provided, having a milling tool that rotates about a tool rotation axis, wherein the milling device has a slide, and in that the milling tool is held on a pivot axis that extends transversely, in particular perpendicular, to the tool rotation axis and through the slide, wherein the slide is designed and the position of the milling tool is selected such that, during milling, a traversing movement is effected by manually moving the slide and advance is effected by pivoting the milling tool about the pivot axis. Also provided is a method for milling within a slot of a component, in particular within a blade root receiving slot of a turbomachine, using a milling device.

An automated cross slide system having a cross slide with a back plate, a front plate and a saddle. The back plate can have a pair of end caps, a pair of linear guides, a first ball screw, a first gear box, a first servo motor, a first drive, and a first manual feed knob and the front plate can have a pair of end caps, a pair of linear guides, a second ball screw, a second gear box, a second servo motor, a second drive, and a second manual feed knob. The system can have a power supply, a communications hub with a processor and data storage connected to a network. The system can have a library of specification profiles and a human machine interface for accessing the library and controlling the first and second drives to cut a target piece in accordance with a selected specification profile.
