Abstract
An abrasive device may include first ring-shaped container filled with a liquid abrasive medium. A second container may be arranged next to the first container and filled with a second liquid abrasive medium. A pivoting arm may be arranged between and above the containers and can be pivoted along a pivoting direction. A drag device may be arranged on the pivoting arm. The drag device may lead a gas turbine blade on a carrier arm through the abrasive medium.
Claims13
An abrasive device for smoothing a surface of a gas turbine blade, the abrasive device comprising:
- a drag device to drag the gas turbine blade through an abrasive medium in a drag direction around a first axis;
- and
- a carrier arm provided on the drag device, the carrier arm to support the gas turbine blade for
- pivot action around a second axis that is perpendicular to the first axis, and
- rotation around a third axis that is perpendicular to the drag direction.
An abrasive device comprising:
- drag means for dragging the gas turbine blade through a dragging medium in a drag direction on an arcuate path around a first axis;
- and
- carrier means for pivoting the gas turbine blade around a second axis that is perpendicular to the first axis, and for simultaneously rotating the gas turbine blade around a third axis that is perpendicular to the drag direction.
An apparatus comprising:
- a drag device to move a work piece along a path around a first axis;
- and
- a carrier arm connected to the drag device, the carrier arm to support the work piece for
- pivot action around a second axis that is perpendicular to the first axis, and
- rotation around a third axis that is perpendicular to the path.
