An apparatus for surface finishing a flange surface of a flange of a pipe includes a frame assembly, a drive assembly coupled to the frame assembly, and a bracket assembly coupled to the frame assembly. The flange is clamped between the frame assembly and the drive assembly. The drive assembly circumferentially translates the apparatus around the pipe. A power tool is coupled to the bracket assembly to perform the surface finishing operation on the flange surface of the flange.

A gearhead for a handheld power tool for machining workpieces, having a housing in which an output that can be connected to a drive of a handheld power tool is accommodated, and also having a tool shaft to which a tool can be coupled, wherein a braking device that can be moved between a braking position and a release position and that acts upon the tool shaft is provided for braking of the tool shaft. A switching device is provided that can be moved between a first switching position, in which the tool shaft is connected to the output in a power transmitting manner and in which the braking device is transferred into the release position, and a second switching position, in which the tool shaft is decoupled from the output and in which the braking device is transferred into the braking position.

A grinding machine, manually displaceable on a track in a longitudinal direction of the track, for grinding rails of the track. The grinding machine includes a support frame which is designed for rolling on the rails via guide rollers and which carries an energy module and a work module. The work module has a pivotable grinding unit. The grinding unit includes an electric motor and a grinding tool powered by the same. The grinding unit is supported in a motor frame for pivoting about a longitudinal axis, and the motor frame is adjustably mounted relative to the support frame.

According to one example, an assembly for a repair of a compressor casing of a gas turbine engine is disclosed. The assembly can comprise: an arcuate track configured to be mounted to the casing, wherein when mounted to the casing the track is configured to be spaced in a substantially concentric arrangement from an inner surface of the casing; a carrier coupled to the track and movable therealong; and a machining device mounted to the carrier, the carrier configured to adjust at least an axial position of the machining device relative to the track for machining the inner surface of the casing.

A device is adapted to be coupled to a conveyor system and recondition at least one chain of the conveyor system. The device includes a base and at least one attachment element coupled to the base. The attachment element is adapted to detachably couple the device to the conveyor system. At least one reconditioning element is coupled to the base, and the reconditioning element is adapted to engage and recondition the chain as the chain moves relative to the reconditioning element. At least one biasing element is coupled to the reconditioning element, and the biasing element urges the reconditioning element away from the base and into engagement with the chain.
