Abstract

The method and machine are for preparing an annular workpiece from tube stock, using a part-off rolling tool. The tool is advanced radially of the tube stock to a depth approx. equal to the desired bore dia. of the workpiece so as to partially sever a length from the tube stock. The inside of the length is then machined to the desired bore dia. The machining either causes the length to be fully severed from the rest of the tube stock or leaves it connected to it by a thin annular band. In the latter case the rolling tool is then advanced further to fully sever the length from the rest of the tube stock.
