ABSTRACT:
A telescopic spindle for a machine tool. The spindle has a sleeve at its rear end and the end of the spindle can slide inside the sleeve over a "compensation" stroke C1, the sleeve being capable of entering inside the body of the machine to travel over a stroke C2, so that the total stroke of the spindle is equal to C1+C2. This serves to reduce the total amount of space taken up by the machine tool.
