Abstract
A boring machine including a rotatable boring bar carrying a tool holder that is movable radially of the boring bar, wherein a sensor is provided on the tool holder to sense the proximity thereof to a work piece having a variable radius of curvature in a plane perpendicular to the boring bar.
Claims11
A boring machine, comprising:
- a rotatable boring bar carrying a tool holder that is movable radially of the boring bar, wherein a sensor is provided on the tool holder to sense the proximity thereof to a work piece having a variable radius of curvature in a plane perpendicular to the boring bar, and the tool holder exchangeably holds a rotatable disc having an abrasive and/or cutting periphery.
A boring machine, comprising:
- a rotatable boring bar carrying a tool holder that is movable radially of the boring bar, wherein a sensor is provided on the tool holder to sense the proximity thereof to a work piece having a variable radius of curvature in a plane perpendicular to the boring bar, and the tool holder is carried by a carriage that is movable axially along the boring bar.
A boring machine, comprising:
- a rotatable boring bar carrying a tool holder that is movable radially of the boring bar, wherein a sensor is provided on the tool holder to sense the proximity thereof to a work piece having a variable radius of curvature in a plane perpendicular to the boring bar, and the boring bar is rotatable between supports adapted to removably mount in a turbine half-casing.
