Abstract
An in situ machine is provided for refurbishing a bore in a workpiece. The achine includes a shaft which is adapted to be fixed to the workpiece in axial alignment therewith. A tubular boring element is concentrically mounted for rotation about the fixed shaft and is adapted to extend into the workpiece bore. A cutting head is slidably mounted on the boring element for reciprocable movement therealong. A device is provided for rotating the boring element and cutting means, and another device, which is responsive to the rotating device, is provided for advancing the cutting head along the boring element.
Claims11
An in situ machine for refurbishing a bore in a workpiece comprising:
- a shaft which is adapted to be fixed to the workpiece in axial alignment therewith;
- a tubular boring element concentrically mounted about the fixed shaft for rotation therearound and adapted to extend into the workpiece bore;
- cutting means;
- and
- means interconnecting the cutting means to the boring element for rotating the cutting means about the fixed shaft and automatically advancing the cutting means along the boring element an incremental amount for each revolution of the cutting means about the fixed shaft.
