PURPOSE:To perform squeeze spinning work without breaking a work by measuring a gap between a mandrel and the work by a measuring sensor, and then moving a tool by an NC driver through a discriminating arithmetic part. CONSTITUTION:When a gap measuring sensor 5 detects a gap, the tracking data of a working tool 4 is discriminated, operated, and corrected by a discriminating arithmetic part 8 so that the gap disappears. The resulting data is inputted to an NC driver 9 and on the basis of the data, roller 4 is put close to or away from a mandrel 1, and in an excellent work state where the work 2 is brought into contact with the mandrel 1, a die is applied. |
